CBE Seminar: “Dynamics and Reactivity of Supported Catalysts in the Subnanometer Regime” (Ayman Karim, Virginia Tech)

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

Abstract Supported noble metal catalysts are extensively used in industry and their catalytic performance is strongly affected by particle size and shape. In the last decade, supported single atoms and subnanometer clusters have attracted a lot of interest since they maximize the metal utilization and have shown extraordinary catalytic properties for many reactions. In this […]

CBE Seminar: “Role of Water in Underwater Adhesion” (Ali Dhinojwala, University of Akron)

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

Abstract Roughness and wetness can disrupt interfacial bonding and reduce adhesion, and this phenomenon is of relevance for many biological and engineering applications. I will discuss how roughness affects both dry and wet adhesion as well as provide an overview of our current theoretical understanding in this area. My specific interest is in underwater adhesion, […]

PICS Colloquium: “Modeling Lone Pair Dynamics in Materials”

PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

Materials properties are governed by the structure and dynamics of the bonds between their constituent atoms. In addition to covalent, metallic, and ionic interactions that we typically think about, lone pair electrons can result in non-trivial directional interactions in materials. I will discuss molecular interactions involving lone pairs in materials, focusing on results from molecular […]

Career Steps Before Graduation Seminar

Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United States

On Friday, April 12,2024, the Department of Materials Science and Engineering is hosting an information session dedicated to equipping you with insights on the essential steps to secure a career after graduation, with staff from UPenn Career Services and ISSS (International Student and Scholar Services) lending their expertise on prevailing job trends and providing guidance […]

CBE Doctoral Dissertation Defense: “A Multifaceted Approach to CO2 Emissions Reductions and Removals” (Maxwell Pisciotta)

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

Abstract: The scientific consensus is that climate change is not only actively occurring, but that it is irrevocably due to human activities associated with greenhouse gas emissions. Greenhouse gas emissions have been accumulating in the atmosphere since the beginning of the industrial revolution. This thesis specifically focuses on one greenhouse gas in particular, CO 2 […]

CBE Seminar: “Creating Real Steak Without the Cow: Using Insights from Wine and Biopharmaceutical Production to Commercialize Cultivated Meat”

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

Abstract Between a growing global population and increased consumption of meat from developing countries, it is projected that meat production will have to increase by at least 60% by 2050 to meet demand. It is unlikely that expanded conventional animal agriculture alone will be able to meet this need. Therefore, alternatives to conventional meat will […]

CBE Doctoral Dissertation Defense: “Identifying Material Fingerprints of Relevance to Understand Adsorbate-Surface Interactions Using First Principles Modeling and Machine Learning” (Genesis Quiles-Galarza)

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

Abstract: Adsorption of chemical species on surfaces of materials is one of the critical phenomenon governing the reactivity and activity of the material for surface and interface driven chemical reactions. At the core of the analytical $d$-band adsorption model is the correlation between the adsorption energy of a chemical species (molecule or reaction intermediate) on […]

John A. Quinn Distinguished Lecture in Chemical Engineering: “Exploring the Physics, Materials Science, and Biological Implications of Polyelectrolyte Complexation” (Matthew Tirrell, University of Chicago)

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

Abstract The richness of liquid-liquid phase separation behavior in mixtures of oppositely-charged polyelectrolyte has been greatly illuminated recently in the polymer physics literature. Precise determinations of phase diagrams, measurements of interfacial tension, scattering measurements of chain configurations, and increasingly insightful theory are all producing a clearer understanding of these phenomena. In parallel, physics is also […]
