Electrochemical potential window of battery electrolytes: the HOMO-LUMO misconception

Hubert Girault, Pekka Eero Peljo

A widespread misconception in the lithium ion battery literature is the equality of the energy difference of HOMO and LUMO of the solvent with the electrochemical stability window. HOMO and LUMO are concepts derived from approximated electronic structure t ...

Structured light enables biomimetic swimming and versatile locomotion of photoresponsive soft microrobots

Peer Fischer, Tian Qiu, Hao Zeng

Microorganisms move in challenging environments by periodic changes in body shape. In contrast, current artificial microrobots cannot actively deform, exhibiting at best passive bending under external fields. Here, by taking advantage of the wireless, scal ...
