Heteroatom-Doped Graphene-Based Materials for Energy-Relevant Electrocatalytic Processes
TL;DR: In this paper, the authors provide a concise appraisal on graphene doping methods, possible doping configurations and their unique electrochemical properties, including single and double doping with N, B, S, and P. In addition, three-dimensional heteroatom-doped graphene structures have been discussed, and those especially can be directly utilized as catalyst electrodes without extra binders and s.

Crystal structure of oxygen-evolving photosystem II at a resolution of 1.9 Å.
TL;DR: The crystal structure of photosystem II is reported, finding that five oxygen atoms served as oxo bridges linking the five metal atoms, and that four water molecules were bound to the Mn4CaO5 cluster; some of them may therefore serve as substrates for dioxygen formation.
