Abstract Herein, the ferrocene redox indicator-based surface film characteristics of spinel lithium manganese oxide (LMO) were evaluated. The pre-cycling of spinel LMO generated a film on the LMO surface. The surface film deposited on LMO surface sup

A thermal ground plane (TGP) device spreads concentrated heat effectively into a relatively large area. The TGP selected for this study utilizes bubble pumping, instead of wicking, to effectively circulate fluid inside its chamber and keep the hot ar
