SUMMARY:How green hydrogen is made
DESCRIPTION:ChE Seminar Series Presents: \nMarc T.M. Koper \nLeiden Institute of Chemistry \nLeiden University\, Leiden\, The Netherlands \nAbstract:  \nThe electrocatalytic production of hydrogen through water splitting is a necessary approach for storing (excess) renewable electricity as chemical energy in fuels\, and for making green hydrogen as a building block for the chemical industry. Here\, I will discuss recent advances and challenges in the mechanistic understanding of electrochemical H2 formation. Specifically\, I will show that H2O activation is influenced by an intricate interplay between surface structure (both on the nano- and on the mesoscale)\, electrolyte effects (pH\, ion effects) and mass transport conditions. This complex interplay is currently still far from being completely understood. \nBio: \nMarc Koper is Professor of Surface Chemistry and Catalysis at Leiden University\, The Netherlands. He received his PhD degree (1994) from Utrecht University (The Netherlands) with a thesis on nonlinear dynamics and oscillations in electrochemistry. He was an EU Marie Curie postdoctoral fellow at the University of Ulm (Germany) and a Fellow of Royal Netherlands Academy of Arts and Sciences (KNAW) at Eindhoven University of Technology\, before moving to Leiden University in 2005. His research in Leiden focuses on fundamental aspects of electrocatalysis\, theoretical and computational electrochemistry\, and electrochemical surface science\, in relation to renewable energy and chemistry. He has received various national and international awards\, among which the Spinoza Prize of the Netherlands Organization for Scientific Research (2021)\, Allen J. Bard Award for Electrochemical Science of The Electrochemical Society (2020)\, the Netherlands Catalysis and Chemistry Award (2019)\, and the Faraday Medal (2017) from the Royal Society of Chemistry. He is currently President of the International Society of Electrochemistry.

SUMMARY:Leveraging the Natural Cellular and Biomolecular Interactions in Blood for the Design of Targeted\, Anti-Inflammatory Particle Therapeutics
DESCRIPTION:ChE Seminar Series Presents:  \nDr. Omolola (Lola) Eniola-Adefeso \nAssociate Dean for Graduate and Professional Education in the College of Engineering at the University of Michigan-Ann Arbor \nAbstract:  \nVascular-targeted particle therapeutics offer the possibility of increased drug effectiveness while minimizing side effects often associated with systemic drug administration. Factors that influence the likelihood of targeted particle therapeutics to reach the vascular wall are the ability to identify: 1) a disease-specific target\, 2) the appropriate drug carrier type and geometry for efficient interaction with the vascular wall\, and 3) a drug-carrier combination that allows for the desired release of the targeted therapeutics. Our work focuses on probing the role of particle geometry\, material chemistry\, and blood rheology/dynamics on the ability of vascular-targeted drug carriers to interact with the blood vessel wall – an important consideration that will control the effectiveness of drug targeting regardless of the targeted disease or delivered therapeutically. This presentation will highlight the carrier-blood cell interactions that affect drug carrier binding to the vascular wall and alter critical neutrophil functions in disease. The talk will present the material design parameters for optimal drug carriers’ design for active and passive use in treating acute lung injury and other inflammatory diseases. \nBio: \nDr. Omolola (Lola) Eniola-Adefeso is the University Diversity and Social Transformation Professor of Chemical Engineering and Biomedical Engineering and the Associate Dean for Graduate and Professional Education in the College of Engineering at the University of Michigan-Ann Arbor.  She received a doctoral degree (2004) in Chemical and Biomolecular Engineering at the University of Pennsylvania. She was a postdoctoral associate in the Pediatrics/Leukocyte Biology at Baylor College of Medicine. Dr. Eniola-Adefeso joined the faculty of Chemical Engineering at the University of Michigan in 2006\, where she runs the Cell Adhesion and Drug Delivery Laboratory.   Since she arrived at Michigan\, Dr. Eniola-Adefeso has received several honors and awards\, including the NSF CAREER Award\, American Heart Association Innovator Award\, and most recently\, the BMES MIDCAREER Award. She is a fellow of the American Institute for Medical and Biological Engineering (AIMBE) and the Biomedical Engineering Society and serves as Deputy Editor for Science Advances. Her research is currently funded by multiple grants from the NIH NHLBI\, American Heart Association\, and the National Science Foundation. \n

SUMMARY:Engineered cellular models to explore human disease heterogeneity
DESCRIPTION:ChE Seminar Series Presents:  \nAlison McGuigan\, PhD \nProfessor\, Chemical Engineering & Applied Chemistry\, University of Toronto \nAbstract: \nEx vivo culture models provide powerful tools to interrogate the role of tumour heterogeneity in human cancers. Patient-derived organoids (PDOs) are emerging as powerful models to capture the genetic heterogeneity of human tumors. However\, extrinsic factors present in the tumor microenvironment (TME) of a tumour\, such as the presence of stromal cells and gradients of small molecules such as oxygen\, also affect cancer phenotype and response to therapy. This talk will describe tissue-engineered platforms we have developed 1) to enable controlled assembly and disassembly of organoid structures to study the impact of both genetic and microenvironmental heterogeneity on tumor cell behavior and 2) to explore tumour microenvironment remodelling\, heterogeneity in response to therapy\, and potential to re-grow after therapy. \nBio: \nDr. Alison McGuigan is a Professor in Chemical Engineering and Applied Chemistry and the Institute for Biomedical Engineering at University of Toronto. She obtained her undergraduate degree from University of Oxford\, her PhD from University of Toronto working\, and completed Post Doctoral Fellowships at Harvard University and Stanford School of Medicine. Dr. McGuigan research group is focused on the engineering of tissue models to explore mechanisms of disease and regeneration. Dr. McGuigan has established strategies to generate multi-component tissue systems with specified organization. Furthermore\, she has pioneered the design of tissue platforms for smart data acquisition\, with a focus on stratifying heterogeneous bulk data by cell population\, by spatial location\, or by time. In recognition of Dr. McGuigan’s work she has received numerous awards including the 2013 TERMIS-AM Young Investigator Award\, and the Canadian Society for Chemical Engineering Hatch Innovation Award. In 2018 was elected to the Royal Society of Canada-College of New Scholars\, Artists and Scientists and in 2022 she was elected a Fellow of TERM by the Tissue Engineering and Regenerative Medicine International Society. She serves on the executive leadership team of CFREF Medicine by Design program and on the Centre for Commercialization of Regenerative Medicine (CCRM) incubation and outreach committee.

SUMMARY:Modular and Composite Approaches to Engineering Challenging Tissues with Polysaccharide Materials
DESCRIPTION:ChE Seminar Series Presents: \nHoward W.T. Matthew\, PhD \nProfessor\, Chemical Engineering\, Wayne State University \nAbstract: \nPolysaccharides have long been recognized as polymeric materials with an array of properties that have made them indispensable for applications ranging from adhesives to property-enhancing nanomaterials.  As a result\, they have found wide acceptance as food and drug additives.  Over the past thirty years\, a growing body of work has served to raise their profile as effectors and modulators of receptor-based phenomena including immune recognition as well as cell-matrix\, cell-pathogen\, and cell-growth factor interactions.  However\, these materials remained underutilized as components of implantable systems.  Within the last decade\, the explosion of research in tissue engineering and regenerative medicine has increased demand for biologically active materials\, and polysaccharides are receiving greater attention for their ability to facilitate tissue assembly and organization in vitro and in vivo.  While many polysaccharides possess potentially useful biological activities\, their mode of application has mainly been in bulk hydrogel form.  The Matthew group has been working with polyelectrolyte ionic complexes formed between oppositely charged polysaccharides.  These ionic complex membranes can be rendered as hollow microcapsules of controllable size.  This presentation will describe our ongoing studies focused on deploying these capsules as a versatile tool for generating tissue organoids and as a platform for assembling vascularized tissues with a range of physical and biological properties. \nBio: \nHoward Matthew is a Professor of Chemical Engineering and Materials Science at Wayne State University (WSU) in Detroit\, Michigan.  He received a B.Sc. degree in Chemical Engineering (1984) from the University of the West Indies\, Trinidad.  After two years in the food processing industry\, he joined Wayne State University for graduate studies\, receiving an M.S. degree in 1988 and a Ph.D. in 1992.  He conducted two years of postdoctoral research at Harvard Medical School and the Massachusetts General Hospital.  He then joined the WSU faculty as an Assistant Professor in 1994.  He is a recipient of the National Science Foundation’s Early Faculty CAREER Award (1996)\, and was elected as a Fellow of the American Institute of Medical and Biological Engineering (AIMBE\, 2012).  His research spans the fields of biomaterials and tissue engineering\, focusing on the use of polysaccharide materials in tissue design and assembly.  His work has two broad themes: modulating the mechanics and biological activity of polysaccharide materials; and developing methods to apply these materials in cell and tissue-based therapies.  Target applications include: heart valves for pediatric applications\, designing transplantable liver tissue\, and regeneration of musculoskeletal structures after surgical or traumatic loss.  To date\, Prof. Matthew has been research supervisor for over 40 graduate students 55 undergraduates and 43 high school students. \n

SUMMARY:Figuring it out: Student Engagement towards Conceptual Understanding and Disciplinary Practice
DESCRIPTION:ChE Seminar Series Presents: Milo Korestky\nMcDonnell Family Bridge Professor\nCo-Director\, Institute for Learning on Research and Instruction (IRLI)\nDepartment of Chemical and Biological Engineering\nDepartment of Education\nTufts University \nAbstract: \nThere has been considerable emphasis recently in transitioning chemical engineering classroom instruction from transmission-based lectures to active learning. Active learning has been defined broadly as “anything that you have your students do in class that gets them to actively engage with the material you’re trying to teach.”  This talk focuses on student engagement – that is\, how students take up the challenging and complex work that we ask them to do as they form into professional engineers. I explore fundamental questions about student engagement in the active learning classroom: Engagement in what? Are there different kinds of engagement? I contrast two forms of engagement. The first looks at engagement for conceptual understanding using the Concept Warehouse\, a tool developed around concept-based active learning. The second addresses engagement in disciplinary practices. When engaged in disciplinary practices\, students use the concepts and discourses of engineering to “get somewhere” on an engineering task (develop a product\, gain a better understanding). Neither way is inherently more correct or better\, rather they are representations of learning that might provide useful ways to think about design choices within a certain context. \nBiography: \nMilo Koretsky is the McDonnell Family Bridge Professor and co-Director of the Institute for Research on Learning and Instruction (IRLI) at Tufts University. He holds a joint appointment in Chemical and Biological Engineering and in Education. He received his B.S. and M.S. degrees from UC San Diego and his Ph.D. from UC Berkeley\, all in Chemical Engineering. He currently has research activity in areas related to engineering education. His group works on integrating technology into effective educational practices that promote the use of higher-level cognitive and social skills in engineering problem-solving and in promoting change towards motivating faculty to use evidence-based instructional practices. A particular focus is on what prevents students from being able to integrate and extend the knowledge developed in specific courses in the core curriculum to the more complex\, authentic problems and projects they face in professional practice. Dr. Koretsky has received recognition through university and international awards and is a Fellow of the American Society of Engineering Education and a Fellow of the Center for Lifelong STEM Education Research.

SUMMARY:Catalytic treatment of water contaminated with halogenated hydrocarbons
DESCRIPTION:ChE Seminar Series Presents: \nUmit Ozkan\, Chair & University Distinguished Professor \nDepartment of Chemical and Biomolecular Engineering\, Ohio State University \nAbstract:  \nGroundwater contamination by halogenated compounds such as trichloroethylene (TCE) is an environmental concern due to their high level of toxicity and their potential impact on drinking water. Hydrogenation of chlorinated compounds offers an efficient and cost-effective way of decontaminating groundwater since it eliminates the chlorinated compounds by catalytically converting them to hydrocarbons and hydrogen chloride. Although promising conversions have been obtained with the palladium-based state-the-art catalysts\, slow kinetics at low temperatures and low concentrations as well as deactivation due to reduced sulfur and chlorine species (SO42-\, HS–\, Cl–) are still recurring problems. To overcome these issues\, we are using a newly-developed material\, a swellable organically modified silica (SOMS) as a catalyst scaffold. SOMS is a very hydrophobic material\, but it has a very high affinity for organics.  These characteristics allow the organic contaminants to concentrate inside the pores\, near the active sites\, hence helping the kinetics. Hydrophobicity serves as a deterrent to deactivation by keeping the water-dissolved poisons away from the active sites.  Activity measurements performed in liquid and gas phases as well as catalyst characterization results will be presented. \nBiography: \nUmit S. Ozkan is a Distinguished University Professor and a College of Engineering Distinguished Professor at The Ohio State University.  She received her Ph.D from Iowa State University in 1984 and joined the faculty of The Ohio State University in 1985. Between 2000 and 2005\, she also served as the Associate Dean for Research in the College of Engineering. She held Visiting Scientist and Visiting Professor positions at the French IRCE-LYON and  Université Claude Bernard\, respectively.   Currently\, she is the Chair of the Chemical and Biomolecular Engineering Department. \nHer current research interests are focused on heterogeneous catalysis and electro-catalysis. Professor Ozkan has held and continues to hold many leadership positions in several professional organizations\, including ACS\, AIChE\, and North American Catalysis Society.   She is on the Editorial Boards of Catalysis Today\, Journal of Molecular Catalysis\, Catalysis Letters\, Topics in Catalysis\, The Royal Society of Chemistry Catalysis Book Series\, Applied Catalysis B\, ACS Applied Energy Materials\, Catalysis Reviews in Science and Engineering\, ACS Catalysis\, Journal of Catalysis\, and Nature Sustainability.   Dr. Ozkan is a Professional Engineer registered in Ohio.  She is a fellow of the American Association for the Advancement of Science (AAS)\, American Institute of Chemical Engineers (AICHE)\, and American Chemical Society (ACS). \nProfessor Ozkan is the recipient of many honors and awards among which are ACS Henry H. Storch Award (2017)\, ACS Energy and Fuels Distinguished Researcher Award (2012)\, John van Geuns Lectureship Award at the Van’t Hoff Institute at the University of Amsterdam (2010)\, Iowa State University\, Professional Achievement Citation in Engineering (2010)\, AIChE Mentorship Excellence Award (2009)\, Fulbright Senior Scholar Award (2007)\, the Society of Women Engineers Achievement Award (2002. In 2013\, she was honored by a special volume of Topics in Catalysis. The volume included contributions from 35 different research groups from 12 different countries. In 2019\, she was again honored\, this time by a special volume of Catalysis Today. \nIn her research group\, Dr. Ozkan has advised and mentored over 100 graduate students\, post-doctoral researchers and honors students.

SUMMARY:Deep Learning Guided Electrified Interfacial Chemical Processes
DESCRIPTION:ChE Seminar Series Presents: \nDr. Fanglin Che\, Assistant Professor \nDepartment of Chemical Engineering\, University of Massachusetts Lowell \nAbstract:  \nThe usability and costly storage issues of renewable electricity from solar or wind energy become major challenges on a global scale due to the daily and seasonal variability of sunlight or wind and the geographic inequality of energy needs. A promising solution to address the above challenges lies in electrified modular chemical processes\, which provide a sustainable approach to store the solar and wind electrical energy chemically. Theoretically determining and quantifying the roles of electrified interfacial structure and field-dipole interactions on controlling the activity and selectivity of chemical processes and then integrating these roles to establish deep collaborations between machine learning and electrified interfacial chemical processes is crucial for rationally designing these electrified modular systems for energy storage and sustainable chemical production. This talk will focus on two examples\, one is organic-inorganic interface and its impact on electrocatalysis of carbon dioxide and the other one is field-dipole interaction effects on sustainable ammonia synthesis. \nBiography: \nDr. Fanglin Che joined in Chemical Engineering department at UMass Lowell as an Assistant Professor in September\, 2019. Dr. Che earned her Ph.D. in Chemical Engineering at Washington State University in December\, 2016\, under the advisement of Prof. Jean-Sabin McEwen. From 2017 to 2018\, she worked on electrocatalysis with Prof. Edward Sargent at University of Toronto as a Postdoctoral Researcher. From 2018 to 2019\, she worked on microwave heating as a Postdoctoral Researcher in the Department of Chemical and Biomolecular Engineering at University of Delaware in Prof. Dionisios G. Vlachos’s laboratory. The overarching goal of Dr. Che’s research at UMass Lowell is to advance the knowledge of electrified interfacial phenomena via building data-driven multi-scale and multi-physics computational models. A special focus is placed on electric field-induced chemistry\, electrocatalysis\, plasma catalysis\, and microwave catalysis. Her group is currently funded by NSF\, Navy\, and Army.

SUMMARY:Design of Polymer Electrolytes with Superionic Ion Transport
DESCRIPTION:ChE Seminar Series Presents: \nRachel A. Segalman\, PhD. \nDepartment Chair\, Chemical Engineering\, University of California\, Santa Barbara \nAbstract: \nProgress toward durable\, high-energy density lithium-ion batteries has been hindered by instabilities at electrolyte-electrode interfaces leading to poor cycling stability\, and by safety concerns associated with energy-dense lithium metal anodes. Solid polymeric electrolytes (SPEs) can help mitigate these issues\, however SPE conductivity is limited by sluggish polymer segmental dynamics. Transport through the free volume of ordered\, superionically conductive domains results in decoupling of ion motion and polymer segmental dynamics. Although crystalline domains are conventionally detrimental to ion conduction in SPEs\, we demonstrate that semicrystalline polymer electrolytes with labile ion-ion interactions and tailored ion sizes exhibit excellent lithium conductivity (1.6 mS/cm) and selectivity (t+~0.6-0.8). This allows for simultaneous optimization of typically orthogonal properties including conductivity\, Li-selectivity\, mechanics\, and processability. \nBio: \nRachel A. Segalman received her B.S. from the University of Texas at Austin and Ph.D from the University of California\, Santa Barbara. She was a postdoctoral fellow at the Université Louis Pasteur before joining the faculty of UC Berkeley and Lawrence Berkeley National Laboratories from 2004-2014.  During a portion of this time she also served as the Materials Science Division Director at Lawrence Berkeley National Laboratories. In 2014\, she moved to UC Santa Barbara to be the Kramer Professor of Chemical Engineering and Materials and became Department Chair of Chemical Engineering in 2015. In 2018 she also became the Schlinger Distinguished Chair of Chemical Engineering and the Associate Director of the UT/UCSB/LBL EFRC: Center for Materials for Water and Energy Systems.  She is the co-editor of the Annual Reviews of Chemical and Biomolecular Engineering and an associate editor of ACS Macro Letters.  Segalman’s group works on controlling the structure and thermodynamics of functional polymers for energy applications including polymeric ionic liquids and semiconducting and bioinspired polymers.  Among other awards\, Segalman received the Journal of Polymer Science Innovation Award\, the Dillon Medal from the American Physical Society\, the Presidential Early Career Award in Science and Engineering\, is an Alfred P. Sloan Fellow and a Camille Dreyfus Teacher Scholar. She is also a Fellow of the American Physical Society and was elected to the American Academy of Arts and Sciences and the National Academy of Engineering. \n  \nPlease contact a.ramsey@northeastern.edu for the remote link.

SUMMARY:Open-Shell Molecules: A Radical Design for Organic Optoelectronic Materials
DESCRIPTION:ChE Seminar Series Presents: \nDr. Mark S. Chen \nAssistant Professor \nDepartment of Chemistry\, Lehigh University \nAbstract: \nOpen-shell molecules possess unpaired electron density (radical character)\, which makes them intriguing candidate materials for many optoelectronic applications. Air-stable structures have been reported\, but most require lengthy synthetic sequences with limited generality. Our lab has developed a concise strategy for rapidly accessing a variety of bisphenalenyls from commercial starting materials. We used this method to synthesize a neutral biradicaloid\, Ph2–s-IDPL\, and several novel heteroatom-substituted\, π-radical cations. One such molecule is O-substituted (Ph2-PCPL)(OTf)\, which displays electrostatically-enhanced\, intermolecular covalent-bonding interactions that impart remarkable charge transport properties. Specifically\, we have discovered that mixing soluble PCPL derivatives with polystyrenesulfonate (PSS) enables the formation of water-processable\, n-type conductive organic films that demonstrate high optical transparency (>94% transmission)\, electrical conductivity (σrt < 117 S/cm)\, and electron mobility (μe < 322 cm2 V-1 s-1). In these composites\, PSS not only serves as a counterion\, but also promotes n-doping and solution-phase aggregation\, which leads to molecular ordering in solid-state. We have also discovered a N-substituted\, red emissive\, π-radical cation [(Ph2-PQPL)(OTf)] that is structurally distinct from all other luminescent radicals\, and achieves rare antiambipolar charge transport in field-effect transistors. N-substituted bisphenalenyls also display self-sensitized and reversible reactivity with dioxygen that shows potential for use in colorimetric oxygen sensors and for on-demand singlet oxygen release. \nBio: \nMark Chen is an Assistant Professor in the Department of Chemistry at Lehigh University. He received his B.A. and Ph.D. in Chemistry from Harvard University with M.-Christina White developing catalytic C-H bond oxidation methodologies. As a Dreyfus postdoctoral fellow in the lab of Jean Fréchet at U. C. Berkeley\, he led a team developing polymeric and molecular materials for organic electronic devices. Since coming to Lehigh University\, the Chen Lab has investigated the synthesis of open-shell organic molecules and their application to optoelectronic materials and devices. Mark is the recipient of several awards\, including a Kaufman Foundation New Investigator Award (2015) and NSF CAREER Award (2021). \nPlease contact a.ramsey@northeastern.edu for the zoom link to attend remotely.

SUMMARY:Development of micro-magnets for bio-medical applications
DESCRIPTION:ChE Seminar Series Presents: \nNora M. Dempsey \nUniv. Grenoble Alpes\, CNRS\, Grenoble INP\, Institut NEEL\, 38000 Grenoble\, France \nAbstract: \nMagnetic flux sources are used to manipulate biological entities (cells\, embryos\, DNA\, proteins…). The magnetic field gradients produced by a flux source scales up as its size is decreased\, resulting in increased force per unit volume. Hard magnetic flux sources are particularly interesting for compact and / or portable applications while the force produced by soft magnetic flux sources on a target object are easily varied.  There is thus great potential for using both hard and soft micro-magnets as flux sources in biology and medicine. \nIn this talk I will briefly review our work on the development and micro-patterning of magnetic films\, in particular Rare Earth – Transition Metal hard magnetic films\, and the low-cost fabrication of micro-magnet arrays based on powder-polymer composites. I will then give examples of bio-medical applications of the micro-magnets we have developed. To wrap up I will discuss potential uses of high intensity pulsed magnetic field sources in bio-medical applications. \nBiography: \nNora Dempsey received her PhD from Trinity College Dublin\, Ireland\, in 1998. Since then she has been based at Institut Néel\, CNRS Grenoble in France. She works on functional magnetic materials\, with an emphasis on hard magnetic materials in film form. These films are used as model systems to guide the development of bulk magnets\, and also to develop micro-magnets for applications in biology\, medicine\, telecommunications and energy management. \nPlease contact a.ramsey@northeastern.edu for the remote seminar link.

SUMMARY:Accelerating the Transition to Carbon Neutrality
DESCRIPTION:ChE Seminar Series Presents: \nMadga Barecka\, Ph.D. \nPost-Doc at University of Cambridge\, Research Centre in Singapore \nAbstract \nTransition to Net Zero 2050 requires immediate and drastic changes in the current manufacturing methods. This transformation is difficult to realize without disrupting the existing industries and putting at risk the delivery of the products that our society relies on. To address this challenge\, I proposed an alternative approach: use of novel\, carbon-neutral technologies such as CO2 electrolysis as a retrofit\, which operates in parallel to an existing chemical plant\, can be installed with a minimum disruption to the ongoing manufacturing activities and leads to a meaningful reduction of the carbon footprint. This technology\, Carbon Capture On-site Recycling\, will be illustrated with examples of several chemical manufacturing processes\, where\, if fully deployed\, it could allow to save annually up to 10 Gt of CO2 emissions by 2050. \nThis work is a part of my broader vision on disrupting the global carbon cycle through both discovery and scaling of circular production methods for chemical\, pharmaceutical and environmental sectors. How to encourage the industry to change and adopt innovative technologies? How to functionally reproduce photosynthesis to deliver carbon neutral chemicals? How to improve the access to medicines for those most exposed to distribution injustice? In my talk\, I will discuss my current and future research that will significantly contribute to answering these questions. \nBio \nDr. Magda H. Barecka is a Post-Doc at University of Cambridge\, Research Centre in Singapore. She is interested in accelerating the adoption of CO2 conversion\, powered by renewable energy\, and the development of economically viable and scalable carbon neutral production methods. Dr. Barecka holds a PhD degree from TU Dortmund University (Germany) and was the first PhD candidate to be awarded the title as a Double Diploma certificated together with Lodz University Technology (Poland). She is a chemical engineer with expertise in process intensification\, retrofitting and design\, developed in academia and private sector. As a part of her PhD thesis\, she developed a methodology supporting implementation of intensified technologies in the chemical manufacturing\, which was transferred to Industry (Processium company\, France/Brazil). After the completion of her PhD\, she joined pharmaceutical/fine chemicals sector in Switzerland and worked on the design of manufacturing lines\, as well as established collaborations with Academia towards the development of algorithms accelerating process development. After this\, she came back to the research sector to deploy her process design experience in the field of carbon capture and utilization. Dr. Barecka is currently working in the intersection of CO2 electrolysis process design\, reaction optimization\, integration with renewable energy sources\, and techno-economic analysis for CO2-based manufacturing methods that can disrupt the carbon cycle. \nPlease contact a.ramsey@northeastern.edu for the remote seminar link.

SUMMARY:Capture and Conversion of CO2 – Towards CO2 Recycling
DESCRIPTION:ChE Seminar Series Presents: \nJuliana Carnerio\, Ph.D \nPostdoctoral Research Fellow \nSchool of Chemical Engineering & Biomolecular Engineering\, Georgia Institute of Technology \nAbstract: \nOur current global fossil-based economy produces significant environmental\, economic\, and social challenges. Such complex challenges are the defining issues of our time\, pushing society toward stepwise decarbonization of our energy and consumption economy. Ideally\, the aim is a more just and reliable economy\, with minimal social and environmental burdens and the redistribution of economic and environmental benefits. To this end\, a circular carbon economy – which integrates energy\, chemical\, and waste management sectors – offers an opportunity to rethink our linear model. With the CO2 recycling system playing a central role in this proposed model\, the scientific community responds with efforts in R&D to create a suite of CO2 mining and utilization technologies. \nIn the first part of my talk\, I will tackle the electrochemical conversion of CO2 at an elevated temperature regime\, using Reversible Solid Oxide Electrochemical Cells (RSOECs). The optimization of the performance of the oxygen and fuel electrodes in these cells has been hindered by the limited understanding of the factors that govern the O2 and CO2 chemistries. As such\, I will discuss our efforts toward developing design principles for the identification of optimal electrocatalysts for these electrode reactions. We used a combination of theoretical calculations\, controlled synthesis\, advanced characterization\, and testing to show that the binding energy of atomic oxygen can be used as an activity descriptor for these processes. It was found that a compromise in the oxophilicity of the electrocatalyst was required to achieve optimal activity and stability. Our theory-guided design principles successfully identified: (i) Cobalt-doped La2NiO4 as a highly active material for O2 electrocatalysis\, and (ii) Fe\, the most oxophilic metal tested\, as a highly active metal for CO2 electrochemical reduction. However\, Fe exhibited unstable electrochemical behaviors induced by the oxidation of the metal under electrochemical CO2 reduction conditions in SOECs. This phenomenon ratifies the importance of the strength of oxygen binding on the electrocatalyst surface as a descriptor of activity and stability for CO2 electrolysis in SOECs. \nIn the second part of my talk\, I will highlight our work on adsorptive materials for the direct air capture (DAC) of atmospheric CO2. We explore the role of atmospheric humidity as an essential stability parameter for DAC processes employing solid amine adsorbents. We demonstrate this by using prototypical class 1 aminopolymer-type solid sorbents that allow for flexibility in the support use. Sorbent deactivation was investigated by means of several complementary factors\, including (i) the relative loss in amine efficiency determined via time-course CO2 sorption\, (ii) elemental analysis\, and (iii) in situ IR spectroscopy to obtain an understanding of the role of water on the sorbent degradation process. Our findings provide important insights into the relevant parameters that impact the effective design of DAC sorbents and processes for different climatic environments\, allowing tailoring of sorbent formulations to overcome the challenges associated with highly varied conditions in which a DAC process must operate. \nBio: \nDr. Juliana Carneiro is a postdoctoral research fellow in the School of Chemical Engineering & Biomolecular Engineering at the Georgia Institute of Technology with Professor Christopher W Jones. She received her Ph.D. in Chemical Engineering from Wayne State University in 2019 under the supervision of Prof. Eranda Nikolla. Her research interests lie in developing active\, selective\, and stable electrocatalysis for electrochemical conversion and separation processes\, including the electrochemical recycling/upcycling of post-consumer plastics\, the capture and storage of CO2 from oceans\, and the capture and conversion of atmospheric CO2. She is the recipient of several awards\, including\, but not limited to the 2017-2018 Ralph H. Kummler Award for Distinguished Achievement in Graduate Student Research\, 2018 Women’s Initiatives Committee’s (WIC) AIChE Travel Award\, and the prestigious Student Presentation Awards at the (i) Gordon Research Conference on Catalysis\, (ii) the Michigan Catalysis Society.

SUMMARY:Platinum: Not as Noble as We Thought
DESCRIPTION:ChE Seminar Series Presents: \nArthur Shih\, Ph.D. \nLeiden Institute of Chemistry\, Leiden University\, The Netherlands \nAbstract \nUnderstanding of catalysis at a fundamental level has historically lagged behind its commercial counterpart with the Haber-Bosch ammonia synthesis process and catalytic converters as pertinent examples [1]. This historical paradigm\, however\, is shifting with the advancement of computing prowess and collaboration. We will discuss how experiments and density functional theory (DFT) computations led us to discover that platinum\, a noble metal that is frequently utilized as a catalyst in the cathode of fuel cells\, restructures when the voltage is held constant between fuel-cell relevant voltages of 0.6 and 1.0 V on a reversible hydrogen electrode scale (VRHE) [2]. \nAn anomalous reduction feature at ~0.53 VRHE was observed on a Pt(111) single crystal in Ar-saturated HClO4 after holding at the fuel-cell relevant voltage of 0.8 VRHE (Figure 1). Decades of research has established that Pt(111) in HClO4 oxidizes H2O to adsorbed *OH between 0.6 and 1.0 VRHE [3-5] and this current model is unable to explain the anomalous feature. Using a combination of computational\, electrochemical\, spectroscopic\, and imaging probes\, we find that holding the voltage between 0.6 and 1.0 VRHE results in a mildly-roughened Pt(111) surface [6]\, presumably due to an *OH-induced release of surface stress. The catalytic performance of this mildly roughened Pt(111) was tested for the oxygen reduction reaction (ORR) and carbon monoxide oxidation (CO Oxidation) where it was found that the ORR rate is seemingly structure insensitive and CO Oxidation rate is surprisingly structure sensitive [7]. Overall\, this discovery demonstrates the importance of understanding how dynamic and steady operating conditions influence the electrode-electrolyte interface – critical for predicting\, designing\, and improving current commercial technologies and opening doors for the development of future technologies. \nBio \nArthur Shih’s research interests are in catalysis for the sustainable production of chemicals and energy\, with emphasis on utilizing reaction kinetics and spectroscopy to understand catalytic mechanisms. He obtained his bachelor’s in Chemical Engineering from the University of Michigan during which he developed computer-based resources with H. Scott Fogler for his textbook “Elements of Chemical Reaction Engineering” and explored several research areas ranging from cancer detection to polymers to CO2 capture. He then earned his Ph.D.\, also in Chemical Engineering\, from Purdue University with Fabio H. Ribeiro where he investigated the thermal-catalytic reduction of toxic nitrogen oxides in catalytic converters. Inspired by the growth and prowess of computational chemistry coupled with a desire to capitalize on cheap renewable electricity for the environment\, he then moved to Leiden University and completed a postdoc in Chemistry with Marc Koper on the electrocatalysis of water splitting to H2 and O2 over well-defined single crystal electrodes. During that time he collaborated with several computational chemists around the world. He is currently a postdoctoral scholar in Materials Science and Engineering at Northwestern University with Sossina Haile working on nitride catalysts for high temperature electrochemical ammonia synthesis. \nIf unable to attend in person\, please contact a.ramsey@northeastern.edu for the link.

SUMMARY:Materials Exhibiting Biomimetic Carbon Fixation: Kinetic Analysis\, Mechanistic Insights\, and Material Design
DESCRIPTION:ChE Seminar Series Presents: \nDorsa Parviz\, Ph.D. \nDepartment of Chemical Engineering\, Massachusetts Institute of Technology \n Abstract: \nPopulation growth and climate change necessitate a paradigm shift from current chemical and materials production methods to more sustainable approaches with a negative carbon footprint. In view of this\, I will introduce carbon fixing materials (CFM) as a new synthetic platform that\, like plants\, utilize sunlight to photocatalytically reduce ambient CO2 and add to an ever-extending carbon backbone. First\, I will describe a mathematical framework enveloping the main functions of carbon fixing materials to answer basic questions about the kinetics regimes of operation\, photocatalytic requirements\, and limits of functional materials in CFMs. I will also present mechanistic insights on the photocatalytic reduction of CO2 to C1 intermediates as desired intermediates for producing value-added products from CO2. In the second part of my talk\, I will focus on state-of-the-art 2D nanomaterials and strategies for surface engineering these materials in the colloidal state\, addressing challenges in their characterization for applications in photocatalysis. \nBio: \nDorsa Parviz is a postdoctoral researcher at the Massachusetts Institute of Technology\, working with Prof. Michael Strano in the Department of Chemical Engineering. She earned her Ph.D. in 2016 from Texas A&M University under the guidance of Prof. Micah Green\, where she pioneered techniques for high-yield production of 2D nanomaterials\, investigated their colloidal interactions and assembly\, and designed tailored nanosheet-based polymer composites and 3D networks for structural and electrode applications. During her postdoc\, she developed carbon fixing materials at MIT\, establishing a high-throughput photocatalytic reaction screening system to accomplish this vision. In addition\, she has led the research on the preparation and characterization of biocompatible engineered 2D nanomaterials with tailored structure and properties for nanotoxicity studies at NIEHS Nanosafety Center. \nIf unable to attend in person\, please contact a.ramsey@northeastern.edu for the seminar link.

SUMMARY:ChE Seminar Series: Catalytic Oxidation of Methane\, the “Other” Greenhouse Gas
DESCRIPTION:ChE Seminar Series Presents: \nDr. Michael Harold \nDepartment of Chemical & Biomolecular Engineering\, University of Houston \nAbstract: \nThe abundant domestic natural gas resources has motivated the accelerated development of natural gas powered vehicles and stationary engines.  With the primary constituent of abundant NG being methane (CH4)\, NG has a higher H:C ratio than gasoline or diesel and therefore its combustion produces less CO2.   However\, CH4 is itself a more potent greenhouse gas (GHG) than CO2 with a GHG potential about 85 times that of CO2. Uncombusted CH4 must be eliminated in order to clear the way for the growth in the NG engine market. Current state-of-the-art Platinum Group Metal (PGM) catalysts are ineffective in eliminating methane. Our research is focused on the study and development of a new class of cost effective structured catalysts with reduced PGM loadings for both stoichiometric and lean methane oxidation. For stoichiometric oxidation we show that the combination of spinel mixed metal oxide (AB2O4) addition and lean-rich feed modulation results in significant enhancement in the catalyst performance. Detailed study of feed modulation parameters (frequency\, amplitude)\, catalyst design (composition\, architecture) and spatiotemporal reactor features provide insight into and optimization of the underlying mechanism. The enhancement is attributed to the transient oxidation of methane conversion inhibitors CO and H2 by the spinel. Up to a 30% reduction in PGM loading is possible with negligible loss in performance. For lean oxidation we study and develop an in situ method to regenerate methane oxidation catalysts. Periodic reductant (H2\, CO) pulsing mitigates the detrimental water poisoning of Pd-Pt catalyst. The pulsing is able to regenerate the catalyst deactivated by water by removal of OH-groups from the catalysts surface\, but also promoted its activity after repeated application of pulsing for several hours. This state of high activity is stable for several hours under the tested lean conditions. \nBio: \nMike Harold is the Cullen Engineering Professor in the Department of Chemical and Biomolecular Engineering at the University of Houston.  With expertise in catalysis and reaction engineering\, Harold is the author of more than 180 peer-reviewed papers and book chapters and has given over 350 presentations and invited lectures.  Harold received his BS at Penn State and PhD from the University of Houston (UH).  He joined the faculty at University of Massachusetts at Amherst in 1985 where he became Associate Professor.  In 1993 Harold joined DuPont Company\, where he held technical and managerial positions.  In 2000 Harold became the Dow Chair Professor and Department Chair at UH\, a position he held for 16 years. Mike was appointed Editor-in-Chief of the AIChE Journal in 2012 and will soon end his 10 year term. His honors include the Excellence in Applied Catalysis from the Southwest Catalysis Society in 2019\, the Ester Farfel Award at UH in 2013\, and AIChE Fellow in 2014. \nPlease contact a.ramsey@northeastern.edu for the seminar link.

SUMMARY:ChE Seminar Series: Orchestrating Cellular Regeneration at Organ Scale
DESCRIPTION:ChE Seminar Series Presents: \nYvon Woappi\, Ph.D. \nK99/R00 MOSAIC Fellow at Harvard Medical School\, Brigham and Women’s Hospital \nAbstract \nLarge scale tissue damage\, such as organ failure and burn injury\, is a leading cause of morbidity and death. However\, the mechanisms underlying full regeneration of organs remain poorly understood. As the largest organ system in the body\, the integumentary system is a composite tissue evolutionarily adapted for healing. Consequently\, its complex physiology requires multifaceted cooperation between several distinct cell populations and cell lineages of embryologically distinct origins. Equally integrated within this dynamic process is local immune response that produces mitogenic and inhibitory signals throughout the restoration procedure. There remains a significant gap in understanding how these processes are orchestrated\, and how various skin cell populations from distinct developmental lineages functionally cooperate to regenerate tissue at organ scale. My research seeks to characterize the molecular language of tissue healing and to harness this malleable dialect for the regeneration of mammalian tissues. Through the development of organoid models of wound regeneration\, and the coupling of these systems with novel gene-editing approaches\, my work is enabling the functional understanding of the multifaceted cellular events executed throughout restorative healing. This seminar will describe these high throughput technologies and will illustrate their utility in identifying novel regulators of tissue healing. \nBio \nDr. Yvon Woappi’s passion for life sciences ignited during his childhood in Douala\, Cameroon and was magnified after his family immigrated to Hanover\, Pennsylvania during his middle school years. He went on to receive his B.S in Biology at the University of Pittsburgh\, and his Ph.D. in Biomedical Sciences as a Grace Jordan McFadden Fellow under Lucia Pirisi at the University of South Carolina. There\, he developed a 3D skin organoid system to study the relationship between epithelial regeneration and virus-induced neoplasia. He subsequently completed postdoctoral training in the Harvard Dermatology Research Training Program at Brigham and Women’s Hospital where he established novel in vivo gene editing systems to understand the contribution of distinct cell lineages in tissue regeneration and cancer. He was recipient of the 2019 Engineering the Genome Award\, and was later selected as a Rising Star in biomedical sciences and engineering by MIT\, Cornell\, BU and Columbia University. Most recently\, Dr. Woappi was awarded the NIH K99/R00 MOSAIC award to launch his independent research career. Away from the bench\, he is an ardent proponent of inclusive excellence and currently sits on the advisory committee for the NIH Continued Umbrella Research Experiences Program at Harvard Medical School.

SUMMARY:ChE Seminar Series: Unwinding Anxiety: An App Based Mindfulness Program
DESCRIPTION:ChE Seminar Series Presents: \nDr. Nancy Lasson\, DO\, FACP\, DipACLM \nPrimary care provider and medical director of the primary care group at the Women’s Medicine Collaborative of LifeSpan Physician Group in Providence\, Rhode Island \nAbstract:  \nAnxiety can be managed by understanding reward-based learning and using mindfulness to interrupt unwanted behavior. Habits form to promote survival. The underlying mechanism is based on reward-based learning. There are areas of the brain where habits run on autopilot. The neo-cortex\, or new brain\, is where mindfulness can help break the cycle of unwanted habits of anxiety. Anxiety as an emotion has associated behaviors\, including worry\, rumination\, stress eating\, and smoking. The goal of unwinding anxiety is to offer an alternative to autopilot habits by employing mindfulness techniques. Multiple studies have demonstrated significant efficacy in this tool. Mindfulness is the awareness that occurs when paying attention in the present moment intentionally\, without judgment. The felt experience of mindfulness replaces autopilot habits like worry and stress. \nBio: \nDr Nancy Lasson is a primary care provider and medical director of the primary care group at the Women’s Medicine Collaborative of LifeSpan Physician Group in Providence\, Rhode Island. She is also a clinical assistant professor of medicine\, Warren Alpert Medical School at Brown University. Dr. Lasson received her B.A. at the University of Pennsylvania in religious studies and cultural anthropology. She studied medicine at the Philadelphia College of Osteopathic Medicine. She is board certified in both internal medicine and lifestyle medicine. She was a primary care physician in Limestone Medicine and Pediatrics of Christiana Care in Wilmington\, Delaware where she achieved a “Top Doctor in Delaware” award in internal medicine. She is a Fellow of the American College of Physicians and Diplomat of the American College of Lifestyle Medicine. Recently she became certified as a behavior change facilitator.  Dr. Lasson’s clinical interests include women’s medical issues and care; preventive medicine\, especially cholesterol management; coronary artery disease and cancer screening; end-of-life care for patients and their families; and mindfulness practices. She is passionate about struggles of the human soul.

SUMMARY:ChE Seminar Series: Game-Inspired Approaches to Engineering Education Across the Curriculum
DESCRIPTION:ChE Seminar Series Presents: \nDr. Daniel Burkey \nAssociate Dean of Undergraduate Education and Diversity\, Professor-in-Residence in Chemical and Biomolecular Engineering\, and a University Teaching Fellow at University of Connecticut \nAbstract: \nGame-based educational techniques can be an interesting and novel approach to active learning in engineering courses. Because games often exist within their own rule sets\, they can allow students to explore scenarios and make choices that they wouldn’t otherwise make because they are appropriate within the context and the rules of the game. In this talk\, we discuss two different projects involving game-based learning. In the first\, we explore multiple game-based approaches to teaching engineering ethics to freshmen engineering students in a multidisciplinary setting. At the beginning of the semester\, students are given a baseline survey to quantify the sophistication of their ethical reasoning. Over the course of the semester\, different game-based interventions are given to the students\, and the survey instrument again is used to determine any changes in their ethical reasoning. The game-based interventions by their nature allow students to explore ethical reasoning in the context of behavioral ethics. In the second project\, we discuss the development and use of a digital video game to teach process safety to senior chemical engineering students. Our research team developed a survey instrument to gauge the sophistication of student thinking about process safety. Students completing the survey instrument and then completing similar scenarios in the game show statistically significant differences in the types of responses they make\, indicating that different reasoning modes may be activated by the game due to its more authentic and realistic portrayal of the material. \nBio: \nDaniel D. Burkey is the Associate Dean of Undergraduate Education and Diversity\, Professor-in-Residence in Chemical and Biomolecular Engineering\, and a University Teaching Fellow at the University of Connecticut. Dr. Burkey holds his B.S. in Chemical Engineering from Lehigh University in Bethlehem\, PA\, and his M.S.C.E.P. and Ph.D. in Chemical Engineering from the Massachusetts Institute of Technology. Prior to UConn\, he held positions at Northeastern University and at GVD Corporation in Cambridge\, MA. Since joining UConn in 2010\, Dr. Burkey’s area of research has focused broadly on engineering education\, and specifically on moral and ethical development of engineering students\, process safety education\, and game-inspired educational techniques. Dr. Burkey currently serves as a Director of the Education Division of AIChE\, where he runs the Future Faculty Mentoring Program. He is a past program chair of the ASEE Chemical Engineering Division and serves on the publications board of Chemical Engineering Education. In 2020\, he was inducted into the Connecticut Academy of Science and Engineering (CASE) for his contributions to engineering education in the state. In addition to his many teaching awards\, Dr. Burkey is also the recipient of the 2020 AICHE Education Division Innovation Award for his contributions to new pedagogies in chemical engineering education\, as was recently awarded the 2021 ASEE Corcoran Award for the best paper in Chemical Engineering Education in the previous year.

SUMMARY:ChE Seminar Series: Designing Optically Active Semiconductor Nanoparticles for Biomedical Applications
DESCRIPTION:ChE Seminar Series Presents: \nDr. Allison Dennis \nAssistant Professor\, Biomedical Engineering and Materials Science and Engineering \nBoston University \nAbstract: \nAlthough the unique optoelectronic properties of semiconductor nanoparticle quantum dots (QDs) enable a variety of commercial products including display technology\, solid state lighting\, and photovoltaics\, different design criteria need to be considered to use these nanoparticles in biomedical devices. Here\, I will discuss how we tailor the composition and optical properties of QDs for a variety of biosensing and bioimaging applications. For example\, I’ll describe how we use bright red and green emitting QDs in a rapid\, instrument-free assay to detect small molecules such as antibiotics in complex water samples and use near infrared and shortwave infrared emitters to improve the clarity and resolution of in vivo imaging in mice. Finally\, I’ll describe how biodegradable and biocompatible plasmonic semiconductor nanoparticles could be used to overcome barriers to clinical translation for photoaccoustic imaging and photothermal therapy applications. Notably\, the efforts to remove heavy metals from the nanoparticles compositions also reduces the environmental impact of QDs developed for energy applications. By carefully considering material properties and engineering design choices\, we develop semiconductor nanoparticles for a wide variety of applications. \nBio: \nAllison Dennis is an assistant professor in Biomedical Engineering and Materials Science and Engineering at Boston University. After graduating with a B.S. in Bioengineering and B.A. in German from Rice University\, Prof. Dennis pursued nanobiotechnology research with Prof. Achim Göpferich in the Department of Pharmaceutical Technology at the University of Regensburg in Germany as a Fulbright Scholar. This research direction was continued during her Ph.D. work with Prof. Gang Bao at the Georgia Institute of Technology and post-doctoral research with Dr. Jennifer Hollingsworth at the Center for Integrated Nanotechnologies at Los Alamos National Laboratory. At Boston University\, the Dennis Lab engages the fundamental material properties of heterostructured semiconductor nanoparticles to optimize them for sensing\, imaging\, fundamental photophysical investigations\, and energy applications. The Dennis Lab appreciates past and current support from intramural and extramural sources including the NIH\, NSF\, and the BU Clinical and Translational Science Institute.

SUMMARY:ChE Seminar Series: Detection\, Prediction\, and Visualization of Monolayer Phase Separation on Metallic Nanoparticles
DESCRIPTION:ChE Seminar Series Presents: \nDr. David L. Green \nMaterials Science\, Chemical Engineering\, and Mechanical Engineering Departments \nUniversity of Virginia \nAbstract: The goal is to gain fundamental insights into the factors that dictate the synthesis of monolayer-protected nanoparticles and translate them into rational design strategies for novel functional soft materials. He is interested in monolayer self-assembly\, polymer grafting\, and nanoparticle dispersion. He studies how to exert control over the interface of nanoparticles\, which dictates their degree of compatibility with and assembly in soft materials\, provides reactive sites for attachment of molecules\, such as drug payloads\, and tunes detectable properties\, such as the surface plasmon to a wavelength of interest. David Green is particularly interested in the development of nanoparticles coated with monolayers from mixtures of organic molecules that may also self-assemble into advantageous patterns. As pattern formation in self-assembled monolayers is inextricably linked to their intermolecular interactions\, a key research challenge is the integration of experimental and theoretical techniques to enable de novo design of patterned nanoparticles. \nBio: David Green is an Associate Professor in the Departments of Materials Science and Chemical Engineering at the University of Virginia. He and his team collaborate with chemists\, physicists\, pharmacists\, and oncologists to develop design principles for monolayer-protected nanoparticles.

SUMMARY:ChE Seminar Series: Engineering directed Transport and Collective Dynamics of Charged Colloids under Electric Fields
DESCRIPTION:ChE Seminar Series Presents: \nDr. Carlos A. Silvera Batista \nDepartment of Chemical & Biomolecular Engineering \nVanderbilt University \nEngineering directed Transport and Collective Dynamics of Charged Colloids under Electric Fields \nAbstract: \nGradients in electrical potential (electric fields)\, along with gradients in concentration of ionic species\, are a principal way to control the motion of colloids. The surface and body forces that electric fields exert on anisotropic colloids have opened new applications in self-propulsion\, transport of cargo\, dynamic assembly\, and directed assembly. This talk focuses on the long-range transport of charged colloids\, as well as on the dynamic assembly of anisotropic and active colloids. In the first part\, we present a study of the dynamics of charged colloids under direct currents and gradients of chemical species (electrodiffusiophoresis). In our approach\, we developed a method to simultaneously visualize the progression of concentration polarization and the ensuing dynamics of charged colloids near electrodes. With the aid of confocal microscopy\, we show that the passage of current through water induce the focusing and aggregation of charged colloids away from both electrodes. Preliminary experiments show that this phenomenon can potentially be useful to perform focusing\, trapping and separation operations in lab-on-a-chip devices. In the second part\, we discuss strategies to tailor the propulsion and collective dynamics of Janus particles (JPs) under electric fields. We engineer the relaxation time of JPs by controlling the properties of the medium and the particles. The insights from this study provide helpful quantitative information for the design of colloidal machines with targeted propulsion\, interparticle interactions and collective dynamics. In addition\, our results provide the experimental basis for the design of non-equilibrium strategies for materials fabrication. \nBio: \nDr. Carlos A. Silvera Batista initiated undergraduate studies in chemical engineering at the Universidad de San Buenaventura (Cartagena\, Colombia) and subsequently obtained a bachelor’s degree from the City College of New York (CCNY). Dr. Silvera began his research trajectory as an LSAMP scholar under the guidance of Prof. Ilona Kretzschmar (CCNY). After earning a PhD in chemical engineering from the University of Florida\, Dr. Silvera held postdoctoral positions at the National Institute of Standards and Technology and at the University of Michigan\, where he received the President’s Postdoctoral Fellowship. Currently\, as an assistant professor at Vanderbilt University\, his research interest is on the electrokinetics and directed assembly of colloidal systems.  His research work has resulted in over 20 peer-reviewed publications in high-impact scientific journals\, such as JACS\, ACS Nano\, Langmuir and Science. \n

SUMMARY:ChE Seminar Series: Towards Sustainable Energy and Materials: Carbon Capture\, Utilization and Storage
DESCRIPTION:ChE Seminar Series Presents: \nDr. A.-H. Alissa Park\, Ph.D \nLenfest Earth Institute Professor of Climate Change\nDepartment of Earth and Environmental Engineering & Department of Chemical Engineering\nDirector of the Lenfest Center for Sustainable Energy\,\nColumbia University \nTowards Sustainable Energy and Materials: Carbon Capture\, Utilization and Storage  \nAbstract: \nIn order to meet the ever-increasing global energy demands while stabilizing the atmospheric CO2 level\, the development of carbon capture\, utilization and storage (CCUS) technologies is one of the critical needs. In particular\, there has been significant efforts to develop CO2 capture solvents and some (e.g.\, amine-based aqueous solvents) have shown very promising results. Unfortunately\, the energy requirement for the current aqueous solvent systems is still considered to be too high. Thus\, efforts have been focused on the development of second and third-generation CO2 capture solvents which are often water-free. Nanoparticle Organic Hybrid Materials (NOHMs) are a new class of organic-inorganic hybrids that consist of a hard nanoparticle core functionalized with a molecular organic corona that possesses a high degree of chemical and physical tunability. It has recently been discovered that NOHMs have interesting electrolyte properties which may allow the CO2 capture to be pulled by the in-situ CO2 conversion reactions. The development of these unique nanoscale hybrid materials will not only advance CO2 capture materials design but also introduce unique research opportunities in various energy and environmental fields. This seminar will discuss the challenges and opportunities of different CO2 capture and conversion pathways including Negative Emission Technologies (e.g.\, Direct Air Capture) that can allow the development of circular carbon and hydrogen economy using renewable energy. \nBio: \nAh-Hyung (Alissa) Park is the Lenfest Earth Institute Professor of Climate Change in the Departments of Earth and Environmental Engineering & Chemical Engineering at Columbia University. She is also the Director of the Lenfest Center for Sustainable Energy. Her research focuses on sustainable energy and materials conversion pathways with emphasis on integrated Carbon Capture\, Utilization and Storage (CCUS) technologies addressing climate change. Park group is also working on Direct Air Capture of CO2 and Negative Emission Technologies including BioEnergy with Carbon Capture and Storage (BECCS) and sustainable construction materials with low carbon intensity. Park received a number of professional awards and honors including the U.S. C3E Research Award (2018)\, PSRI Lectureship Award in Fluidization at AIChE (2018)\, ACS Energy and Fuels Division – Emerging Researcher Award (2018)\, ACS WCC Rising Star Award (2017)\, and the National Science Foundation CAREER Award (2009). Park also led a number of global and national discussions on CCUS including the Mission Innovation Workshop on Carbon Capture\, Utilization and Storage in 2017 and the National Petroleum Council CCUS Report in 2019. She is an elected Fellow of AIChE\, AAAS\, ACS\, and RSC. \n  \nPlease contact a.ramsey@northeastern.edu for the remote seminar link.

SUMMARY:ChE Seminar Series: Chemo-mechanics and solid-state batteries
DESCRIPTION:ChE Seminar Series Presents: \nDr. Kelsey Hatzell\, Ph.D \nAssistant Professor in the Andlinger Center for Energy and Environment \nAssistant Professor of Mechanical and Aerospace Engineering \nPrinceton University \nChemo-mechanic and solid-state batteries \nAbstract: Transportation accounts for 23% of energy-related carbon dioxide emissions and electrification is a pathway toward ameliorating these growing challenges.  All solid-state batteries could potentially address the safety and driving range requirements necessary for widespread adoption of electric vehicles. However\, the power densities of all-solid-state batteries are limited because of ineffective ion transport at solid|solid interfaces. New insight into the governing physics that occur at intrinsic and extrinsic interfaces are critical for developing engineering strategies for the next generation of energy-dense batteries. However\, buried solid|solid interfaces are notoriously difficult to observe with traditional bench-top and lab-scale experiments. In this talk\, I discuss opportunities for tracking phenomena and mechanisms in all solid-state batteries in-situ using advanced synchrotron techniques. Synchrotron techniques that combine reciprocal and real space techniques are capable of tracking multi-scale structural phenomena from the nano- to meso-scale. This talk will discuss the role microstructure plays on transport and interfacial properties that govern adhesion. Quantification of salient descriptors of structure in solid-state batteries is critical for understanding the mechanochemical nature of all solid-state batteries. \nBiography: Dr. Hatzell is an assistant professor at Princeton university in the Andlinger Center for Energy and Environment and department of Mechanical and aerospace engineering. Hatzell’s group primarily work on energy storage and is particularly interested at using non-equilibrium x-ray techniques to probe batteries during operando experimentation. \nDr. Hatzell earned her Ph.D. in Material Science and Engineering at Drexel University\, her M.S. in Mechanical Engineering from Pennsylvania State University\, and her B.S./B.A. in Engineering/Economics from Swarthmore College. Hatzell’s research group works on understanding phenomena at solid|liquid and solid|solid interfaces and works broadly i9n energy storage and conversion. Hatzell is the recipient of several awards including the ORAU Powe Junior Faculty Award (2017)\, NSF CAREER Award (2019)\, ECS Toyota Young Investigator Award (2019)\, finalist for the BASF/Volkswagen Science in Electrochemistry Award (2019)\, the Ralph “Buck” Robinson award from MRS (2019)\, Sloan Fellowship in Chemistry (2020)\, and POLiS Award of Excellence for Female Researchers (2021). \nPlease contact a.ramsey@northeastern.edu for the seminar link. \n  \n

SUMMARY:ChE Seminar Series: Learning about Biological Interactions\, Recognition\, and Targeted Delivery Through Surface Forces
DESCRIPTION:ChE Seminar Series Presents: \nDr. Tonya Kuhl \nProfessor and Chair\, Department of Chemical Engineering\, UC Davis \nLearning about biological interactions\, recognition\, and targeted delivery through surface forces \nAbstract: \nThe promoters of cell adhesion are ligands\, which are often attached to semi-flexible tethers that bind to surface receptors on adjacent cells. Drug delivery systems\, such as Stealth Liposomes\, have also attempted to use biological specificity to target therapeutic payloads. Using a combination of Monte Carlo simulations\, diffusion reaction theory\, and direct experiments (surface force measurements)\, we have quantified how polymer tethers alter the interaction and binding/capture based on biospecificity (ligand-receptor binding). Experimental and theoretical results as a function of molecular weight and bi-modal distributions will be discussed to enable rational design. \nBiography: \nTonya Kuhl\, is Professor and Chair of Chemical Engineering\, the co-Director of the UC Davis Coffee Center (and co-instructor and developer of ECH 1 “The Design of Coffee”)\, and a faculty member of the Biophysics and Biomedical Engineering Graduate Groups. Her Bachelors was from the University of Arizona and Ph.D. from UCSB\, both in chemical engineering. Her research interests are in the general area of colloidal science\, self-assembly\, and complex fluids.  In particular\, the Kuhl group studies a wide range of systems from surfactants\, lipids and proteins to polymer coatings\, nanoparticles and confined fluids. The common theme is that “interfaces are where stuff happens”.  Her group studies interfaces by directly measuring the normal interactions (attractive and repulsive) between surfaces and their lateral friction using specialized high resolution force spectroscopy. Complementary x-ray and neutron scattering measurements are used to measure the exact film structure on a molecular level\, enabling a fundamental understanding of how surface film structure and experimental conditions yield the measured properties.  Rather than more empirical\, “guess and test”\, approaches for improvement in properties or functionality – the Kuhl group uses direct measurements and theory to enable predictive modeling and rational design.

SUMMARY:ChE Seminar Series: Materials Innovation in Nanotechnologies
DESCRIPTION:ChE Seminar Series Presents: \nDr. Paulette Clancy\, Ph.D\nHead of the Department of Chemical and Biomolecular Engineering at Johns Hopkins University \nMaterials Innovation in Nanotechnologies \nAbstract\nThere are many problems at the forefront of materials chemistry whose solution is stymied by its inherent complexity. Such problems are characterized by a rich landscape of parameters and processing variables that is combinatorially too large for either an experimental or a computational approach to solve through an exhaustive search. In such cases\, the usual approach is an Edisonian trial-and-error approach\, which inevitably leaves areas of parameter space unexplored. The problems that we have explored are also characterized by a scarcity of data\, since the data are expensive to acquire\, both experimentally and computationally. This makes it an ideal candidate to solve using a Bayesian optimization (BayesOpt) approach.\nWe have used a Bayesian approach to study several problems in self-assembly processes involving materials chemistry. This talk will discuss two mature test cases in which we used BayesOpt extensively to study (1) how to optimize the choice of solvent and halides to produce high quality thin films of lead-based hybrid organic-inorganic perovskites and (2) identify stable and metastable polymorphs of an organic semiconducting material. I will end with some ideas of where the BayesOpt field can expand its use in the chemical sciences and share some “lessons learned” in implementing BayesOpt and machine learning\, which may be helpful to others who decide to start adding machine learning to their research repertoire. \nBiography\nPaulette Clancy is a Professor and the inaugural Head of the Department of Chemical and Biomolecular Engineering at Johns Hopkins University. She is also the Samuel and Diane Bodman Professor Emerita of Chemical Engineering at Cornell. She is the Associate Director of the Hopkins Center for Integrated Structure-Materials Modeling and Simulation. She was the inaugural Director of the Cornell Institute for Computational Science and Engineering for almost 10 years and is reprising a similar role at Hopkins\, chairing our petascale research computing resources\, ARCH.\nHer research group is recognized as one of the country’s leading computational groups in atomic- scale modeling of materials and algorithm development. Her current thrust is to develop machine learning algorithms to accelerate the search for optimal materials processing protocols. Her group has always been focused on electronic materials\, but it also includes more esoteric projects include xenobiology (Life on Titan) and a screening of therapeutic oligomers to maximize antibacterial ability. She has won numerous awards for mentoring\, service learning and civic engagement\, and promoting those from under- represented groups.

SUMMARY:ChE Seminar Series: Biomaterials to unlock the regenerative capacity of tissues
DESCRIPTION:ChE Seminar Series Presets: Dr. Tatiana Segura \nTatiana Segura\, PhD \nProfessor of Biomedical Engineering\, Duke University \nBiomaterials to unlock the regenerative capacity of tissues \nAbstract: Injectable materials that can conform to the shape of a desired space are used in a variety of fields including medicine. The ability to fill a tissue defect with an injectable material can be used for example to deliver drugs\, augment tissue volume\, or promote repair of an injury. This talk will explore the development of injectable materials that are based on assembled particle building blocks\, for tissue repair. We find that using microparticle building blocks to build the scaffold generates a porous network by the space left behind between adjacent building blocks. Due to the injectability of this microporous material we have explored its wide applicability to tissue repair applications ranging from skin to brain wounds. In this talk\, I will describe how MAP scaffolds can modulate the wound healing immune response and lead to regenerative wound healing. \nBiography: Professor Tatiana Segura received her BS degree in Bioengineering from the University of California Berkeley and her doctorate in Chemical Engineering from Northwestern University. Her graduate work in designing and understanding non-viral gene delivery from hydrogel scaffolds was supervised by Prof. Lonnie Shea. She pursued post-doctoral training at the Swiss Federal Institute of Technology\, Lausanne under the guidance of Prof. Jeffrey Hubbell\, where her focus was self-assembled polymer systems for gene and drug delivery. Professor Segura’s Laboratory studies the use of materials for minimally invasive in situ tissue repair. On this topic\, she has published 113 peered reviewed publications to date. She has been recognized with the Outstanding Young Investigator Award from the American Society of Gene and Cell Therapy\, the American Heart Association National Scientist Development Grant\, and the CAREER award from National Science Foundation. She was Elected to the College of Fellows at the American Institute for Medical and Biological Engineers (AIMBE) in 2017. She spent the first 11 years of her career at UCLA department of Chemical and Biomolecular Engineering and has recently relocated to Duke University\, where she holds appointments in Biomedical Engineering\, Neurology and Dermatology.
