Things to know: E-scooters and safety
Penn’s Gene Janda and Joe Romm and Andrew Baldwin of the Philadelphia Fire Department discuss lithium-ion battery fire risks.
As large language models become increasingly adept at synthesizing information and producing human-like responses, many are concerned that malicious actors may use this technology in dangerous ways. Alex Robey, a Ph.D. candidate in the School of Engineering and Applied Science, is developing a first-of-its-kind defense, SmoothLLM.

The Singh Center for Nanotechnology turns 10
Since its founding, the Center’s multidisciplinary approach has been a strength, where researchers from Penn Engineering, Arts & Sciences, and more come together in one space.
Alyssa Hwang, a Ph.D. candidate in the School of Engineering and Applied Science, developed a new framework for evaluating the performance of large language models’ ability to analyze images. Hwang utilized the tool to run a battery of tests on the new ChatGPT-Vision to assess its ability at describing scientific images ahead of its release.

A peek into the future of visual data interpretation
Researchers from Penn have developed a framework for assessing generative AI’s efficacy at deciphering images.
A collaborative team of researchers led by Bo Zhen of the School of Arts & Sciences have created new materials by artificially twisting and stacking two-dimensional atomic “sheets.” New materials control light-matter interaction differently from constituent 2D atomic sheets, paving the way for next-generation laser, imaging, and quantum technologies.

Carbon capture and common misconceptions: A Q&A with Joe Romm
In a conversation with Penn Today, Joe Romm casts a sobering light on “solutions” to curb
climate change.
A collaborative team of researchers led by PIK Professor Christopher B. Murray has observed for the first time composite superstructure growth from nanocrystals in real time. The discovery could enable engineers to more reliably manufacture next-generation materials by combining different nanocrystals. Shown here is an artist's impression of spherical binary nanocrystal superlattices featuring semiconductor (emissive) and magnetic/plasmonic (non-emissive) nanocrystals.
