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: 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.
