MEAM Ph.D. Thesis Defense: “Enhancing Photophoretic Levitation using Three-dimensional Structures for Flight in the Mesosphere and on Mars”

Towne 319 220 S. 33rd Street, Philadelphia, United States

Current propulsion and flight mechanisms limit atmospheric observations. The mesosphere is too dense for satellites and too thin for typical planes and balloons, with similar conditions found in the Martian atmosphere, especially at Olympus Mons. Photophoresis, the movement of gas molecules due to light, has been studied for microscale objects like aerosols and operates optimally […]

BE Doctoral Dissertation Defense: “Right ventricular remodeling in tetralogy of Fallot” (Beth Thompson)

Class of 62 Auditorium, John Morgan Building 3620 Hamilton Walk, Philadelphia, PA

The Department of Bioengineering at the University of Pennsylvania and Dr. Walter Witschey proudly announce the Doctoral Dissertation Defense of Beth Thompson. Title: Right ventricular remodeling in tetralogy of Fallot Advisor: Walter Witschey Date: Thursday, August 22, 2024 Time: 10:00AM EST Location: Class of '62 Auditorium, John Morgan Building Zoom: https://upenn.zoom.us/j/99590672633?pwd=0kNQLS3kz65nZgab4WJrAWAyOB0UEN.1 Meeting ID: 995 9067 […]

CBE Doctoral Dissertation Defense: “High-Pressure Reactions on Metals and Metal Oxides in Mesoporous Silica” (Ching-Yu Wang)

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

Abstract: SBA-15, a type of mesoporous silica, is an attractive support for heterogeneous catalysts due to its high surface area, one-dimensional uniform pore structure, and high thermal stability. However, modifying SBA-15 with metal and metal oxide using conventional wetness incipient impregnation is challenging. In this thesis, Atomic Layer Deposition (ALD) was used to prepare catalysts […]

CBE Seminar: “Self-assembly Models for Crystal Growth and Phase Transitions” (Julia Dshemuchadse, Cornell University)

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

Abstract: How can we make new materials and better understand how their underlying structures form? The direct observation of crystal growth and transitions remains supremely challenging, but gaining insight into these fundamental processes is central to our quest of creating materials in a rational and targeted way, connecting structure to functionality. We build self-assembly models, […]

MEAM Seminar: “CRISPR-Programmed Microfluidic Devices for DNA Detection, Computing and Digital Display”

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

CRISPR is a gene editing technique that allows researchers to quickly and precisely edit genome sequences. Beyond gene editing, CRISPR-Cas systems can be repurposed as a programmable platform for other various applications. In this talk, I will introduce how we use CRISPR technology to program microfluidic devices for DNA detection, DNA computing and digital display. […]

ASSET Seminar: “Bridging the Gap Between Learning and Programming”

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

Abstract:  For decades, we have built software by writing code, but in recent years machine learning has emerged as a new approach to create software with features that would be impossible to code by hand. However, the use of learning to build software risks ignoring some of the lessons we have learned for how to […]

CBE Seminar: “Pressure-induced Nanoparticle Assembly” (Hongyou Fan, Sandia National Laboratories)

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

Abstract: Precise control of structural parameters through nanoscale engineering to improve optical and electronic properties of functional nanomaterials continuously remains an outstanding challenge. Previous work on nanoparticle synthesis and assembly has been conducted largely through solution chemistry at ambient pressure and relies on specific chemical or physical interactions such as van der Waals interactions, dipole-dipole […]

MEAM Ph.D. Thesis Defense: “Controlling Contact Transitions for Dynamic Robots”

Towne 311 220 S. 33rd Street, Philadelphia, United States

Legged robots, robotic manipulators, and their combined embodiment as humanoid robots have received considerable attention across both academia and industry. However, with few notable exceptions, state-of-the-art demonstrations are significantly less dynamic than their biological counterparts. A considerable challenge towards achieving more dynamic robots lies within controlling contact interactions with their environment. Legged robots undergoing impacts […]

MSE Seminar: “Working Safely in the Lab: Navigating Common Laboratory Hazards in MSE Research”

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

EHRS staff will discuss how to work safely in the lab while navigating the changing landscape of materials science and engineering research. The talk will also cover; - Standard orientation topics (physical/bio/chem safety, waste disposal, Workday training, etc.) - The new methylene chloride regulations and how they will affect EHRS and Penn operations. - Safe use of […]
