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 […]

Materials and chemicals impact daily life, as they enable modern healthcare, preservation of food, and delivering performance and efficiency of transportation and infrastructure. The talk will focus on Dow’s vision and path for carbon neutrality. An overview of Dow Chemical’s portfolio and the breadth of chemistries being practiced will be discussed. Dow has a vision […]

My group is developing a roadmap for soft actuating materials to replace bulky electric motors in miniature robots requiring large mechanical work output. First, I will describe the materials microstructure and mechanics of polymeric coiled muscles made by twisting nylon fishing lines, and how these actuators use internal strain energy to achieve a “record breaking” performance. Then I […]

Light-matter interactions form the fundamental basis for numerous phenomena and processes in optical devices. This talk will cover ultra-high-quality (Q) whispering-gallery-mode (WGM) optical microresonators which have an unprecedented capability to trap light in a highly confined volume smaller than a strand of human hair. Light-matter interactions are significantly enhanced in high-quality WGM resonators, creating the […]
