Haoshen Zhou takes a moment to outline the challenges for researchers trying to interface electrodes with solid electrolytes.

Weiguang Xie and Jianbin Xu explain the problems caused by grain boundary defects in perovskite materials used to create solar cells.

Protonic ceramic fuel cells operate in an intermediate temperature range (300–600 °C), avoiding the problems faced by other fuel cell types. Enhanced peak power densities have now been generated using a microstructured anode and a very thin electrolyte.

A new porous nanotube structure is created from pure metallic molybdenum disulfide, which is useful for fundamental electrochemical studies as well as showing good performance as a lithium-ion battery anode.
