SUMMARY:Chemical Engineering Fall Seminar Series: Chaochao Dun
DESCRIPTION:Seminar Title: Fast-Track Materials Discovery Beyond Equilibrium for Energy and Sustainability \nLocation: Egan Center 306 \nAbstract: The development of stable multicomponent materials remains a central challenge in inorganic chemistry and chemical engineering. In systems containing multiple elements\, positive mixing enthalpy\, size and valence mismatch\, and structural incompatibility tend to drive phase separation\, especially under equilibrium conditions. Traditional doping strategies for tuning electronic structure and defect chemistry have had some success but are fundamentally constrained by narrow solid-solution windows. To address these limitations\, we developed a non-equilibrium flame synthesis technique capable of producing multicomponent solid solutions across alloys\, ceramics\, and metal-organic frameworks. This method enables rapid evaporation\, nucleation\, and growth within milliseconds\, establishing a well-defined thermodynamic and kinetic pathway for kinetically trapping metastable phases. When combined with entropy-driven stabilization\, this approach yields two types of material outcomes\, depending on the configurational entropy of the system: high-entropy systems with five or more elements tend to form stable single-phase solid solutions\, while systems with two to four components undergo controlled in situ exsolution in response to mild enthalpic stimuli. This unified strategy is broadly applicable to thermocatalysis\, electrocatalysis\, and critical mineral recovery\, and offers a robust framework for materials design beyond the limits of equilibrium-based methods. \n\n Dr. Chaochao Dun joined Lawrence Berkeley National Laboratory in June 2019 and currently serves as a project staff scientist at the Molecular Foundry. He earned his Ph.D. from the Center for Nanotechnology and Molecular Materials in the Physics Department at Wake Forest University in 2017. At Berkeley Lab\, Chaochao is leading three main research thrusts: (I) synthesizing multicomponent materials via non-equilibrium flame-aerosol method for energy conversion and storage; (II) designing sorbents and redox-active clusters for recovering critical minerals; and (III) mechanism-oriented studies that link defect chemistry and kinetics/thermodynamics to performance\, supported by multi-scale characterization.

SUMMARY:Chemical Engineering Fall Seminar Series: Vincent G. Harris
DESCRIPTION:Seminar Title: Academic Scholarship vs. Entrepreneurship: Research choices in pursuing a career in academia at Northeastern \nLocation: 108 Snell Engineering Center \nAbstract: Success as a faculty member at a Tier 1 research university—fair or unfair—still depends heavily on securing research funding and producing independent\, high-quality scholarship with those resources. Yet\, over the past two decades\, there has been a profound shift in how faculty contributions are evaluated\, with increasing recognition of entrepreneurship as an important dimension of academic impact. \nThis raises an important question: can one pursue academic research that satisfies both the rigorous standards of scholarship and the entrepreneurial expectations of a tenure and promotion (T&P) committee? \nIn this talk\, I reflect on choices made over my three-decade career\, including two decades at Northeastern\, where my research evolved from pure scholarship to one deeply focused on market transition—ultimately leading to a successful spin-out company founded 17 years ago. I will discuss the challenges of bootstrapping a start-up versus pursuing venture capital funding\, and the unique satisfaction that comes from building a company from the ground up. \nMuch of this work was—and continues to be—performed at Northeastern\, with many of the start-up’s employees being former students. The science and engineering behind it sit at the intersection of physics\, chemistry\, materials science\, and RF engineering. \nI will attempt to satisfy the audience’s appetite in S&T by reviewing some of the meaningful contributions made by my students that have been commercialized and impacted society. \n\nVince Harris has built a distinguished career spanning more than 35 years at the intersection of science\, technology\, leadership\, and national security. He has served in diverse roles\, including engineer and physicist; innovator and inventor; mentor and educator; entrepreneur and CEO; Department of Defense branch chief; Department of State policy expert; and global defense teaming lead. \nHis expertise lies in advanced multifunctional materials and RF electronics\, with pioneering contributions to magnetism\, magnetoceramics\, RF device physics\, and novel RF systems. His work has shaped technologies ranging from handheld communication devices to advanced radar platforms\, as well as permanent magnet materials critical to defense and national security. \nIn 2025\, Harris was recognized as the world’s leading researcher in the modern history of ferrites\, ranked first among more than 28\,500 scientists worldwide. His scholarly impact has earned him Fellow status in numerous professional societies\, including AAAS\, APS\, IEEE\, NAI\, the UK Institute of Physics\, and AIIA\, and he has been honored as both a Fulbright Fellow and a Jefferson Science Fellow. His contributions have further been recognized with some of the field’s most prestigious awards\, including the W. David Kingery Award and Edward C. Henry Award from the American Ceramics Society\, the Distinguished Scientist Award from The Minerals\, Metals and Materials Society\, the Lee Hsun Scholar Award and Lectureship from the Chinese Academy of Sciences\, and designation as an IEEE Distinguished Lecturer in RF Applications of Magnetoceramics.

SUMMARY:Chemical Engineering Fall Seminar Series: William Doherty
DESCRIPTION:Seminar Title: Stimulating Excitable Cells with Optosomes: Development of a Non-viral Cell Derived Vesicle Capable of Stimulating Excitable Cells in Response to Light Stimulus \nLocation: 108 Snell Engineering Center \nAbstract: For years\, researchers have studied and developed neuromodulation techniques meant to stimulate and/or inhibit excitable cells both in research and clinical settings. A method to excite cells with light\, termed Optogenetics\, has been researched extensively since its discovery in the early 2000’s. A major constraint of Optogenetics is the expression of the necessary light-gated ion channels most often achieved using a viral vector. While this is not overly concerning in research settings\, clinical applications of optogenetics have been slow to develop as the use of viral vectors in humans presents challenges regarding safety. Additionally\, foreign opsin genes are believed to be a permanent addition to the transfected cells. \nThis dissertation aimed to develop Optosomes; a cell-derived vesicle containing excitatory opsin that couples with excitable cells via Gap-Junctions that conduct the stimulus current from the opsin into the cell. Initial production of Optosomes followed established protocols for producing Giant Plasma Membrane Vesicles (GPMVs) in which small volumes of cytoplasm are encapsulated in a piece of the cell’s plasma membrane. The number of GPMVs produced varied with pH\, cell confluency\, and base medium having a noticeable impact on the number of GPMVs generated. Optosome production required the creation of a stable cell line expressing Channelrhodopsin-2 (ChR2) and connexin-43 (Cx43) proteins required to form Gap-Junctions. Two separate transfections in the series generated a ChR2-Cx43 Hek293 cell line capable of producing Optosomes at a high concentration. Finally\, a mathematical model was built to simulate Optosome stimulation of excitable cells and how changes in the size of Optosomes and cells affect the strength of stimulus generated. The result of these simulations and attempts to stimulate neonatal Cardiomyocytes (CM) in vitro confirmed that the majority of Optosomes produced were too small to generate a stimulus capable of exciting CMs. Production of Optosomes with larger diameters or the use of a different strand of ChR2 is needed to increase the number of Optosomes able to stimulate CMs will be needed moving forward. \nThe results of this dissertation provide the foundation for developing Optosomes as an alternative approach to stimulating excitable cells with light. \n\nAfter spending nearly two years working on the development of a new automated Biomanufacturing system in the Love Lab\, Bill was accepted and enrolled in the PhD program for Chemical Engineering. After finding his home for the next 7 years in the Koppes Lab\, he got to work both on forming his thesis and integrating into the community at Northeastern. In pursuing his Ph. D\, he had started to appreciate how applying mathematical modeling techniques to biological systems offers a whole new perspective when trying to understand the complex innerworkings of the human body. It offered a nice juxtaposition to the time spent in lab running hands on experiments that are less about math and academic prowess and more about technique\, adaptability\, and problem solving in real time. Bill has sed the better part of his twenties working in Research and its why he was so eager to pursue a Ph D as he hopes to work his way into scientist positions overseeing research and development projects. Still residing in Boston\, he hopes to find a position in the New England Area after submitting his Dissertation; staying close to family and friends in the area.

SUMMARY:Chemical Engineering Fall Seminar Series: Zhiyong Gu
DESCRIPTION:Seminar Title: Developing Soldering Nanomaterials for Advanced Materials Joining and Bonding \nLocation: 108 Snell Engineering Center \nAbstract: Joining and bonding methods are not only necessary\, but also quite often critical in materials forming and electronic device manufacturing processes. Among various joining methods\, soldering is one of the most widely used ones\, due to its electrical conductivity and mechanical reliability\, which makes it widely used in a variety of applications such as electronics\, sensors\, transportation vehicles\, and biomedical devices. In this presentation\, I will show the synthesis and development of soldering-driven nanomaterials\, including both nanoparticles and nanowires\, for a variety of micro/nanoscale bonding and joining applications: (1) low-temperature lead-free nanosolders have been synthesized and applied for Cu-Cu joining and bonding; (2) site-selective core/shell and multi-segment nanowires have been synthesized by a combined electrodeposition and chemical reduction method\, which can be aligned and assembled by external force field such as magnetic field or electrical field\, before subsequent soldering. These nanoparticles and nanowires\, and the associated nano-soldering techniques\, have shown great promise in the assembly and construction of functional nanoelectronics and nanodevices. \n\n Dr. Zhiyong Gu is currently a Professor and Chair of the Department of Chemical Engineering at the University of Massachusetts Lowell.
