Author(s)
Cherno Jaye, Daniel A. Fischer, Mokwon Kim, Hyunpyo Lee, Hyuk Jae Kwon, Seong-Min Bak, Gabin Lee, Jung O. Park, Dong-Hwa Seo, Song Bok Ma, Dongmin Im
The development of a cathode for solid-state lithium-oxygen batteries has been hindered in practice by a low capacity and limited cycle life despite their potential for high energy density. Here, a previously unexplored strategy is proposed wherein the

The Structure of Lipids and Keratin in Adhesive Gecko Setae Determined by NEXAFS Imaging

March 1, 2022
Author(s)
Daniel A. Fischer, Cherno Jaye, Katinka R. Holler, Mette H. Rasmussen, Joe E. Baio, Stanislav N. Gorb, Tobias Weidner
Geckos have the astonishing ability to climb on vertical surfaces due to the adhesive properties of fibrous setae at the tips of their toe pads. While the adhesion mechanism principle, based on van-der-Waals interactions of myriads of spatula located at

Elucidating Cathode Degradation Mechanisms in NMC811/Graphite Cells Under Fast Charge Rates Using Operando Synchrotron Characterization
