SUMMARY:Chemical Engineering Spring Seminar Series: Adam Caparco
DESCRIPTION:Protein-based materials for sustainable bioprocesses \nProtein materials\, whose function can be programmed by their amino acid sequence\, possess the potential to address many societal challenges by providing a sustainable and biocompatible alternative to many traditional materials. As an example\, the enhancement of enzymes for biocatalysis serves as a gateway for more sustainable chemical manufacturing. I will demonstrate that by designing an enzyme to fuse to a solid support material\, we can vastly improve its stability and recover the material between reactions for multiple uses. Protein materials also serve as a platform for targeted delivery in medicine and agriculture. I will show that by transforming inactivated plant viruses into spherical nanoparticles for encapsulation\, hydrophobic agrochemicals can be delivered through the soil and paralyze roundworms for pest management with high efficacy. \n\nAdam Caparco\, Ph.D. is a postdoctoral scholar at the University of California\, San Diego in the Department of NanoEngineering. His research under Prof. Nicole Steinmetz is funded by a USDA NIFA fellowship and is focused on using plant virus nanoparticles as agricultural delivery systems for pest management and genetic engineering of plants. Prior to this position\, Dr. Caparco completed his doctoral work in Biomolecular Engineering at Georgia Institute of Technology under Profs. Julie Champion and Andreas Bommarius\, where he focused on using self-assembled protein materials for sustainable biocatalysis. During his doctoral studies\, he was awarded a STEM Chateaubriand fellowship and worked with bioinformaticians and biochemists at Genoscope in France. As an undergraduate\, Dr. Caparco studied Chemical and Biomolecular Engineering at the University of California\, Los Angeles.

SUMMARY:Chemical Engineering Spring Seminar Series: Angela Chen
DESCRIPTION:Engineering Microbial Communication for Sustainable Agriculture \nAgriculture and the global food system accounts for ~30% of greenhouse gas emissions. Therefore\, developing sustainable agricultural technologies is essential for combating and mitigating the effects of climate change. Microbes like bacteria and fungi play pivotal roles in agriculture and food security through complex interactions with plant hosts\, other microorganisms\, and their surroundings. Consequently\, my research aims to investigate how these inter-species and cross-kingdom relationships could be ideal engineering targets for addressing current agricultural challenges. In this seminar\, I will present my work showcasing the power of RNA and nanotechnology in manipulating microbial interactions with the environment and plant hosts. In the first part of my talk\, I will examine how microbes respond to environmental stresses and the use of regulatory RNAs as a genetic platform to manipulate bacterial metal reduction capabilities for the biosynthesis of nanoparticles with unique and enhanced functionality. Following this\, I will then discuss host-microbe interactions and how exploiting RNA-based communication between fungal pathogens and plant hosts can inform next-generation\, nanoparticle-based strategies for plant disease control. Together\, these studies illustrate how understanding and controlling microbial communication will pave the way for new sustainable strategies for reducing agricultural chemical dependence\, improving plant health\, and enabling bioremediation technologies. \n\nAngela Chen is a USDA-NIFA AFRI Postdoctoral Fellow in the Department of Microbiology and Plant Pathology at UC Riverside. Under Prof. Hailing Jin\, she investigates the mechanisms of cross-kingdom RNA trafficking between plants and fungal pathogens to develop nanomaterials for RNAi-based disease control. Prior to UC Riverside\, she received her B.S. in chemical engineering from the Ohio State University and her M.S. and Ph.D. in chemical engineering from the University of Texas at Austin. As an NSF Graduate Research Fellow with Profs. Lydia Contreras and Benjamin Keitz\, she focused on engineering regulatory RNAs in extremophilic bacteria to control bacterial stress response for materials science applications. Outside of research\, Angela is passionate about educating and empowering the next generation of engineers\, having earned a Graduate Certification in Engineering Education. She is also the President of the Riverside Postdoctoral Association\, where she leads initiatives focused on supporting postdocs and broadening STEM access through the creation of diverse and inclusive academic environments.

SUMMARY:Chemical Engineering Spring Seminar Series: Leslie Shor
DESCRIPTION:The “Root” of the Nexus: Soil-Based Biotechnology for a Sustainable Future \nThe function of any biological system depends on local environmental conditions. For bacterial systems\, micro-scale structures including the chemical properties and physical topography of surfaces\, micro-scale chemical gradients\, and patterns of biological distribution impact the diversity\, abundance\, and activity of microbial communities. However\, conventional microbial culture systems do not faithfully emulate microbial habitats; thus\, also cannot reflect realistic functionality of microbial systems. The Shor lab designs\, builds\, and operates emulated microbial habitats to better understand microbial system function. Recent applications include soil-emulating micromodels to accelerate the development of agriculture biotechnology. Emulated soil micromodels (ESMs) systematically replicate physical\, chemical\, and biological features while at the same time enabling direct\, real-time observation of biological responses. ESMs enable systematic hypothesis-driven research of rhizosphere processes and make the development of agriculture biotechnology less time-consuming\, expensive\, and difficult. Our work has shown that the microbe-extracellular matrix system in porous media can double evaporative resistance and dramatically improve system resiliency\, but this functionality is only realized in realistic pore-scale geometries. We have also used ESMs to screen microbes for sustainable agriculture applications and shown viable performance in subsequent full-scale testing. With the loom of climate change and its increasing demands on our water and food systems\, there will be rapidly-increasing demand for more productive and cost-effective sustainable agriculture technology\, including food production technology that also provides reliable and safe terrestrial carbon sequestration. This talk will illustrate how fundamental chemical engineering concepts and methods applied to soils can make important contributions towards a more sustainable future. \n\nLeslie Shor mentors an interdisciplinary team working at the intersection of chemical engineering\, microbiology\, and advanced manufacturing. The focus of her research work is developing biotechnology based on soil microbes to enhance sustainable food production.\nShe is the PI of an EFRI project on separation and elimination of microplastics from treated wastewater effluent. She is active in education\, mentoring\, and outreach initiatives aimed at increasing diversity in STEM and enhancing human welfare through high-tech innovation. Shor earned her BA in Environmental Sciences and Chemistry (double-major) from the University of Virginia\, and her PhD in Chemical and Biochemical Engineering from Rutgers University. Prior to coming to UConn\, she was a research assistant professor at Vanderbilt University. In 2018 she spent six months at the University of Adelaide in South Australia as a visiting faculty member in the School of Chemical Engineering.

SUMMARY:Chemical Engineering Spring Seminar Series: Benjamin Decardi-Nelson
DESCRIPTION:Optimal Control as a Catalyst for Smart and Sustainable Systems \nSustainability is crucial in modern engineering\, particularly in chemical and biological systems. It involves the use of sustainable resources and the development of environmentally friendly\, smart\, and efficient systems that minimize waste and optimize resource use. Central to engineering smart\, sustainable systems is optimal control. However\, integrating optimal control technologies into these systems is challenging due to the complexity of managing large-scale\, constrained\, nonlinear\, and interconnected subsystems\, particularly under uncertain conditions. In this talk\, I will introduce a series of optimal control technologies that contribute to smarter and more efficient systems\, enhancing their sustainability. Specifically\, I will discuss the development and application of (1) model predictive control and (2) reinforcement learning\, which are instrumental in engineering systems that use minimal resources and generate less waste. I will also demonstrate how optimal control is pivotal in advancing sustainable food production in urban areas through the integration of renewable energy and efficient resource management. These advances in optimal control are critical in developing smart\, sustainable systems and are essential for a sustainable future. \n\nBenjamin Decardi-Nelson is an Eric and Wendy Schmidt AI in Science Postdoctoral Fellow in Systems Engineering at Cornell University. Benjamin’s research interest in Process Systems Engineering centers around developing novel computational tools to improve the analysis\, design and control of complex processes and systems\, with the overarching goal of sustainability. Prior to joining Cornell\, he earned his PhD in Process Control from the University of Alberta\, where he developed efficient algorithms and large-scale optimization models for integrated real-time economic optimization and advanced process control of nonlinear process systems. At Cornell\, Benjamin integrates biology-informed AI with optimization to decarbonize future food systems through implicit learning of plant-environment interactions\, and renewable energy integration. His work has been recognized by the Schmidt AI in Science postdoctoral fellowship\, Natural Sciences and Engineering Research Council of Canada (NSERC) postdoctoral fellowship\, among others.

SUMMARY:Chemical Engineering Spring Seminar Series: Professor Bryan James
DESCRIPTION:Design strategies to minimize the environmental impacts of plastic products \nCombatting the existential threats of climate change and pollution requires circularizing and decarbonizing material lifecycles\, reducing persistence\, and eliminating the toxicity of products and processes. Plastics\, the combination of polymer and chemical additives\, contribute significantly to both threats. Despite these harms\, plastics are crucial materials for modern society. In their recent report\, the U.S. National Academies of Sciences\, Engineering\, and Medicine identified material and product design as one of six key interventions to tackle plastic pollution. With this charge\, I will demonstrate how combining concepts learned from the last decade of plastic pollution research with established material selection practices resulted in a quantitative\, multi-dimensional framework for use during product design to minimize the environmental impacts of plastic. By taking this approach\, a sustainability metric was developed for the design of plastic products with low environmental persistence and uncompromised performance. Applying this methodology to commonly littered plastic products (drinking straws and coffee cup lids) demonstrated that accounting for persistence in product design could reduce the societal impacts of plastic pollution by hundreds of millions of dollars for a single product. My findings identify the materials and their properties that deserve development\, adoption\, and investment to create functional and less environmentally impactful plastic products. \n\nDr. Bryan D. James is a Postdoctoral Investigator at the Woods Hole Oceanographic Institution (WHOI). As part of an interdisciplinary team of scientists and engineers within WHOI’s Microplastics Initiative\, his postdoctoral research focuses on understanding the fate\, persistence\, and toxicity of plastic in the ocean to inform the rational design of next-generation materials that are safe for people and the planet. Through this work\, Bryan has collaborated globally with academic colleagues\, NGOs\, and industrial partners and regularly engages with K-12 educators\, mentors community college students\, and advises policymakers. Bryan received his B.A.Sc. in materials engineering from the University of Toronto and his Ph.D. in materials science and engineering from the University of Florida (UF). At UF\, as an NIH F31 Predoctoral Fellow under the mentorship of Prof. Josephine Allen\, Bryan pioneered the use of nucleic acid-collagen complexes for hard and soft tissue engineering and championed investigating sex as a biological variable in biomaterials research\, identifying mechanobiological sex differences in vascular cells. Bryan has been recognized with multiple early career honors and awards\, including being named a Rising Star in Engineering in Health\, a CAS Future Leader\, a DYSS speaker\, and an ACS PMSE Future Faculty Scholar.

SUMMARY:CHE PhD Dissertation Defense: Shicheng Yang
DESCRIPTION:PhD Dissertation Defense: Drug Delivery Systems in Oncology: From Polymeric Implants to Nanomedicine Approaches \nShicheng Yang \nLocation: Hastings Hall 107 & Zoom \nAbstract: Molecular inhibitors\, including PARP inhibitor talazoparib\, CDK inhibitor dinaciclib\, and docetaxel\, are critical in precision cancer therapy\, offering novel therapeutic options for a range of cancers. While demonstrating potent activity as monotherapy or in combination in both preclinical and clinical settings\, challenges such as drug resistance and off-target toxicity persist with these small molecule drugs. To mitigate these issues\, innovative formulation strategies using implants or nanoparticles have been explored. These formulations are designed to alter drug uptake pathways\, resist the emergence of drug resistance\, and minimize direct contact with healthy tissues\, thereby reducing toxicity. This thesis encompasses several nanotechnology approaches in formulating chemotherapy agents and their application across various cancers\, including breast\, ovarian\, pancreatic\, lung\, and prostate. \nIn the context of ovarian cancer\, known for its high mortality rate within the realm of female reproductive system cancers\, more than 15% of cases involve defective BRCA-mediated homologous recombination repair pathways. Talazoparib\, a PARP inhibitor\, has been hindered in its clinical application due to severe systemic side effects. The development of a novel TLZ-loaded PLGA implant (InCeT-TLZ) is reported\, designed for sustained release over 25 days directly into the peritoneal cavity\, targeting BRCA-mutated metastatic ovarian cancer. Results from in vivo experiments indicated a doubling of survival in the InCeT-TLZ treated group compared to controls\, with no significant toxicity observed in surrounding peritoneal organs. This suggests that localized and sustained delivery of Talazoparib can enhance therapeutic efficacy without significant toxicity. Additionally\, the potential of combining CKD inhibitor and PI3K inhibitor with InCeT-TLZ to counteract acquired PARPi resistance was demonstrated in vitro\, indicating a promising approach for enhanced ovarian cancer treatment. \nWhile the biodegradable PLGA implants showed potency\, the conventional solvent-based fabrication methods used to synthesize these implants\, however\, the use of toxic organic solvent and its safety issue pose difficulties for translation to clinical use. To address these challenges\, a scalable\, solvent-free hot-melt extrusion process was introduced for producing PLGA implants iii with docetaxel. This process ensures uniform dispersion of clinically relevant concentrations of the drug without requiring organic solvents. Results showed the bioactivity of incapsulated docetaxel was maintained during fabrication and controlled degradation\, enhancing tumor growth inhibition capabilities both in vitro and in vivo. The implants\, when used intratumorally\, act as both radiosensitizers and continuous chemotherapy sources\, suitable for scale-up in compliance with Good Manufacturing Practices (GMP). \nFurthermore\, the combination of talazoparib and dinaciclib has been studied to overcome PARPi resistance in tumors. The short blood circulation time of dinaciclib and the high toxicity of combination therapies pose significant challenges. Nanomedicine formulations have been developed to address these issues\, creating a nano-cocktail of talazoparib (nTLZ) and dinaciclib (nDCB) to enhance therapeutic efficacy at lower doses. The study showed that these nanoformulations effectively infiltrate tumor cells\, with synergistic effects observed in both BRCAmutant and BRCA wild-type cancer strains\, particularly sensitizing BRCA wild-type cells to PARPi therapy. This approach demonstrates the potential of nanoformulations in broadening the applicability and enhancing the efficacy of combination cancer therapies.

SUMMARY:CHE PhD Dissertation Defense: Jiaming Xu
DESCRIPTION:PhD Dissertation Defense: Molecular simulations of confined deep eutectic solvents for gas separations and liposomes for drug delivery \nLocation: ISEC 332 & Microsoft Teams \nAbstract: This dissertation leverages molecular dynamics simulations to explore the properties of nanoscale materials and interfaces involving gases\, liquids and solids\, traversing the realms of environmental and biological science. This work not only demonstrates the expansive applicability of MD simulations across various scientific disciplines but also highlights their capability to provide profound insights into diverse scientific phenomena. In the segment dedicated to deep eutectic solvents\, our study investigates the behavior of ethaline (mixtures of choline chloride with ethylene glycol at different molar ratios) confined in graphite and titania (rutile) slit pores\, measuring 2 nm and 5 nm in width. This research aims to address the high viscosity issue prevalent in these solvents when saturated with CO2. The results reveal that modifications in the ethylene glycol ratio\, variations in pore sizes\, and the choice of pore wall materials significantly affect the efficiency of CO2/CH4 separation. These findings offer a deeper understanding of how molecular interactions and structural changes in confined spaces can influence the physical properties of DES. \nThe dissertation also delves into the domain of liposomes (nanoparticles formed by a lipid bilayer encapsulating an aqueous core)\, examining the influence of lipid composition and the integration of two distinct small-molecule hydrophobic drugs on their mechanical\, spatial\, and fluid properties. The study encompasses an analysis of the effects of acyl chain saturation and length\, diverse lipid headgroups\, and drug incorporation. Experimental validations\, conducted in collaboration with Prof. Auguste’s laboratory\, support our simulation findings. We discovered that lipids with short-saturated acyl chains and varied headgroups alter the lipid bilayer packing\, resulting in decreased liposome stiffness\, which has been shown promoted drug delivery efficiency. Additionally\, specific drug substances were observed to lower interaction energies within the lipid matrix\, which consequently reduces stiffness and enhances lipid molecule diffusion. This segment of the dissertation provides crucial insights into the design of liposomal formulations\, particularly for drug delivery purposes\, by demonstrating how lipid structure and drug interactions can be manipulated to optimize liposome properties. Overall\, this dissertation underscores the versatility of molecular dynamics simulations in elucidating complex material behaviors and offers valuable contributions to the various engineering fields.

In this seminar\, I will showcase our groundbreaking biphasic tandem catalytic processes\, achieving exceptional carbon-atom efficiencies in converting renewable biomass into biofuels. Additionally\, our innovative sequential catalytic process enables highly selective deconstruction of mixed waste plastics into valuable monomers and fuels. The presentation will also delve into the synergy of integrating direct air capture of CO2 for its utilization in producing value-added carbon-neutral products. Ultimately\, our research aims to implement a holistic approach\, decarbonizing the energy system\, and establishing a sustainable supply of low-carbon intensity chemicals\, materials\, and fuels from renewable and waste carbon resources. \n\nDr. Hongfei Lin is a Professor at the Voiland School of Chemical Engineering and Bioengineering at Washington State University and Chief Scientist in the Energy and Environment Directorate at Pacific Northwest National Laboratory.

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.

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.
