TL;DR: This communication presents a synthesis process to grow MoS2 and MoSe2 thin films with vertically aligned layers, thereby maximally exposing the edges on the film surface, and confirmed their catalytic activity in a hydrogen evolution reaction (HER), in which the exchange current density correlates directly with the density of the exposed edge sites.

TL;DR: It is shown that coating the lithium metal anode with a monolayer of interconnected amorphous hollow carbon nanospheres helps isolate the lithiumMetal depositions and facilitates the formation of a stable solid electrolyte interphase, indicating that nanoscale interfacial engineering could be a promising strategy to tackle the intrinsic problems of lithiumMetal anode cycling.

TL;DR: A composite lithium metal anode is reported that exhibits low dimension variation (∼20%) during cycling and good mechanical flexibility and a full-cell battery with a LiCoO2 cathode shows good rate capability and flat voltage profiles.

TL;DR: A two-step reaction for preparing three-dimensional electrodes composed of CoSe2 nanoparticles grown on carbon fiber paper shows excellent catalytic activity for a hydrogen evolution reaction in an acidic electrolyte, and offers an attractive catalyst material for large-scale water-splitting technology.

TL;DR: In this paper, an oxide selection method was proposed to balance the optimization between sulfide-adsorption and diffusion on the oxides, which showed that better surface diffusion leads to higher sulfide species on electrodes.
