Facile modification using organic acid molecules to neutralize residual alkaline compounds for stabilizing LiNi0.95Co0.04Mn0.01O2 cathode material

Energy Materials and Devices
The presence of residual alkaline compounds in the ultrahigh-nickel layered oxide cathodes (LiNixCoyMn1−x−yO2, x ≥ 0.9) aggravates structural degradation, increases surface reactivity, and promotes slurry gelation, leading to the capacity decay of ...

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.
