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 […]

CBE & BE Seminar: “Targeting the Brain and Behavior to Probe the Dynamics of Aging” (Claire Bedbrook, Stanford University)

Wu & Chen Auditorium

Bio & Abstract: Claire Bedbrook is an engineer and neuroscientist working to extend lifespan by modulating the brain. Claire was trained in chemical engineering at the University of California, Berkeley. She completed her Ph.D. in Bioengineering at the California Institute of Technology with Professor Frances Arnold and Professor Viviana Gradinaru, where she engineered molecular tools […]

CBE Seminar: “Prioritization of Research, Development, and Deployment Pathways for a Circular Bioeconomy” (Jeremy Guest, UIUC)

Wu & Chen Auditorium

Abstract: Societies have prospered using a linear “take-make-use-dispose” approach, extracting natural resources to make products, using them, and ultimately discarding them or their residues. This unsustainable approach has exploited natural resources at a rate that has caused excessive pollution and loss of biodiversity, and is leading to a global climate crisis. In response to this […]

CBE Seminar: “Multifunctionality of MXenes for Sensor Technologies” (Lia Stanciu, Purdue University)

Wu & Chen Auditorium

Abstract: MXenes, a versatile family of 2D materials, have garnered interest for applications in sensing technologies due to their unique combination of conductivity, hydrophilicity, and surface tunability. This talk explores the integration of MXenes into sensor platforms, and discusses their potential in electrochemical, optical, and environmental sensing. Their surface functional groups can be leveraged for […]

Celebration of Community

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

The Cora Ingrum Center for Community and Outreach is planning its annual Celebration of Community gala to showcase Penn Engineering students, staff, and faculty in their multi-talented richness. The event will consist of guest speakers, performances, presentations from student groups, and a variety of cuisines. Do not hesitate to contact Dr. Ocek Eke (ocek@seas.upenn.edu) and […]

CBE Doctoral Dissertation Defense: “Tailoring MXene Chemistry through Composition and Undercoordination for Applications in Hydrogen Chemistries” (Yamilée Morency)

Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

Abstract: Global transition to clean energy relies on the development of efficient hydrogen storage materials and hydrogen evolution reaction (HER) catalysts—two primary chemistries investigated in this thesis. MXenes, a family of two-dimensional transition metal carbides and nitrides, have emerged as promising candidates for hydrogen technologies due to their high electrical conductivity, chemical tunability, and structural […]

CBE Seminar: “Metabolic Engineering and Synthetic Biology for a Sustainable Future” (Hal Alper, UT Austin)

Wu & Chen Auditorium

Abstract: Recent technical advances are leading to a rapid transformation of the chemical palette available in cells, thus making it conceivable to produce nearly any organic molecule of interest—from biofuels to biopolymers to pharmaceuticals. However, these feats require the ability to “hijack” native cellular machinery and metabolism and navigate the complexity inherent in cellular regulation. […]

CBE Doctoral Dissertation Defense: “Understanding and Modulating Interactions between Polymers and Nanoparticles for Effective Catalyst Design in Polymer Upcycling” (Anirban Majumder)

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

Abstract: Despite recent advances in catalytic conversion of plastic waste into high-value chemicals, the interactions between the polymers and catalysts, which are highly porous nanomaterials, are not well understood. Fundamental understanding of these interactions and the ability to modulate them would allow us to design effective catalysts for polymer upcycling reactions. To study the interactions […]

CBE Seminar: “Value-added Transformations in Electrocatalysis and Graduate Education” (Maureen Tang, Drexel University)

Wu & Chen Auditorium

Abstract: Electrifying the chemical industry has been much touted as a path to a low-carbon future, but nearly all pathways of interest are electrochemical reductions. If we want water-to-hydrogen, CO2-to-chemicals, or nitrogen-to-ammonia, from where will we get the electrons? Water-to-oxygen is thermodynamically expensive, kinetically slow, and generates a zero-value product. This talk will discuss two […]

MEAM Seminar: “Microscopic Mayhem: Cancer in Three-Dimensions”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Critical to advancing immunotherapy and cell therapy in cancer is developing a deeper understanding pf the dynamics of immune cell-mediated cytotoxicity. The results from the multidisciplinary effort reported here include numerous measurements and movies of immune cell-mediated cytotoxicity with striking examples of serial killing, foraging, path-tracking, cytokine gradients at tumor margins, and killing dynamics, in […]
