MEAM Ph.D. Thesis Defense: “Photophoretic Light-flyers for Mesospheric Applications”

Lynch Lecture Hall, Cret Wing, CHEM 231 S. 34th Street, Philadelphia, PA, United States

The Earth’s mesosphere plays a crucial role in weather forecasting, environmental conservation, and planetary exploration. However, traditional unmanned aerial vehicles (UAVs) such as balloons or spacecraft face significant challenges when attempting to access this layer. Balloons and airplanes struggle due to the low pressure, while satellites encounter high aerodynamic drag. To overcome these limitations, we […]

BE Seminar: “Mapping and engineering gene expression with chemical and spatial lenses” (Hailing Shi, Broad Institute & MIT)

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Precise RNA expression, tailored to specific brain regions, cell types, and subcellular compartments, is pivotal for orchestrating complex brain functions. In the first part of my talk, I will introduce a confocal imaging-based spatial transcriptomics platform, STARmap, that seamlessly combines in situ hybridization, hydrogel tissue chemistry, and in situ sequencing technologies. Leveraging scalable experimental and computational pipelines, […]

BE Seminar: “Using Computers to Derive Protein Structure from Sparse Data – A Case Study for Mass Spectrometry” (Steffen Lindert, Ohio State)

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Mass spectrometry-based methods such as covalent labeling, surface induced dissociation (SID) or ion mobility (IM) are increasingly used to obtain information about protein structure. However, in contrast to other high-resolution structure determination methods, this information is not sufficient to deduce all atom coordinates and can only inform on certain elements of structure, such as solvent […]

CBE & VIEST Joint Seminar: “Lignin Conversion to Performance-advantaged Fuels, Chemicals, and Polymers” (Gregg Beckham, NREL)

Vagelos Institute for Energy Science and Technology, Room 121 231 S 34th Street, Philadelphia, PA, United States

Abstract: Terrestrial plants harbor renewable carbon resources in their cell walls that can directly contribute to decarbonization of the transportation and materials sectors, but the heterogeneous, aromatic lignin polymer found in plants has long obstructed both natural- and humankind-driven endeavors to deconstruct plant biomass to valuable products. However, viable methods to valorize lignin are essential […]
