When an LNO catalyst with a nickel-rich surface carries out a water-splitting reaction, its surface atoms rearrange from a cubic to a hexagonal pattern and its efficiency doubles. Deliberately engineering the surface to take advantage of this phenomenon offers a way to design better catalysts.

First glimpse of polarons forming in a promising next-gen energy material
Polarons affect a material’s behavior, and may even be the reason that solar cells made with lead hybrid perovskites achieve extraordinarily high efficiencies in the lab. Now scientists have directly seen and measured their formation for the first time.
