12.14.2016 - New paper this week from the Korgel Group! In the Journal of Physical Chemistry C, Xiaotang Liu et al. discuss pore formation during germanium lithiation/delithiation. Check out our paper here.
12.08.2016 - We are saddened to hear of the loss of our group alumna Cindy Stowell, Ph.D. 2005. While a Ph.D. student Cindy studied aspects of colloidal nanocrystals. Cindy stayed in Austin following her graduation, working as a science content developer for Sapling Learning. Recently, Cindy achieved her dream of appearing as a contestant on Jeopardy
11.28.2016 - New paper from the Korgel Group. In JPCC, Yixuan and co-workers investigate gold nanocrystal superlattices and investigate their inverse cooling behavior.
11.28.2016 - Congratulations to the newest graduate of the Korgel Group, Dr. Doug Pernik! Doug successfully defended his thesis this morning, "Micro Solar Cells, Raman Spectroscopy, and Flow Synthesis of Copper Indium Selenide Nanocrystals".
11.09.2016 - New paper from the Korgel Group. Yixuan, Adrien, and other group members write in Nano Letters about silicon nanocrystal superlattices, in collaboration with the Arbiol and Truskett groups. Check out the paper here
Role of Halides in the Ordered Structure Transitions of Heated Gold Nanocrystal Superlattices
It is known that Dodecanethiol-capped gold (Au) nanocrystal superlattices can undergo a surprisingly diverse series of ordered structure transitions when heated. In this paper Yixuan Yu, Brian Goodfellow, Michael R. Rasch and Christian Bosoy showed that in the presence of halide-containing surfactants the nanocrystals ripen at much lower temperature and superlattices undergo various ordered structure transitions upon heating. This work was done in collaboration with Dr. Smilgies at Cornell High Energy Synchrotron Source (CHESS) and was recently published in Langmuir and selected as an ACS Editors' Choice article.
