The Asian American Pioneer Medal Symposium and Ceremony returns in July 2025. We join together to celebrate the transformative contributions made by Asian American pioneers and provide a platform for intellectual exchange and inspiration.
Three PhD defenses and one student award: Congratulations to Yubi Chen, Runqing Yang, and Yujie Quan for successfully defending their PhD theses this month on three wide-ranging topics (charge density waves, Li-ion battery monitoring, and coupled electron-phonon transport). Yujie…
In JACS, we report a high-throughput computational search for materials with strong intrinsic photostriction, non-thermal strain induced by light illumination. While direct calculation of photostriction is difficult, we apply a simple thermodynamic Maxwell equation to convert…
On 1 December 2024, I'll give a talk at a symposium in honor of Professor Gang Chen on the occasion of his 60th birthday. The title of my talk is Conversations with Gang Chen on the Basic Algorithm of Thermodynamics (BAT) I sent him an abbreviated title: BAT Gang Chen 😀
Thanks @ucsantabarbara for covering our recent work!
Researchers at @TeaLab_UCSB have created the first-ever "movie" of electric charges moving between two semiconductor materials. This development offers new insights into semiconductor technology, which powers computers, electric vehicles, and more. 🔋 ow.ly/aPyS50TLcwN
In @PNASNews, we report direct time-resolved electron imaging of photoexcited hot carriers transfer across a semiconductor heterojunction using our scanning ultrafast electron microscope (SUEM). With SUEM, we took movies (with picosecond time resolution) of photocarriers…
We asked ChatGPT to read 8000 paper abstracts and establish a database for magnetocaloric materials, which we then used to train a machine learning model to predict new magnetocaloric materials. With this approach we discovered 11 new materials, including one with the best…
