TL;DR: Nitrogen-doped graphene/graphene-tube nanocomposites are prepared by a hightemperature approach using a newly designed cage-containing metal-organic framework (MOF) to template nitrogen/carbon and iron precursors that universally exhibit high oxygen-reduction activity in acidic, alkaline, and non-aqueous electrolytes and superior cathode performance in Li-O2 batteries.

TL;DR: Mechanisms consistent with these observations are presented for the cobalt-catalyzed hydrogenation of olefins and ketones and the acceptorless dehydrogenation of alcohols.

TL;DR: The synthesized 20% Pt/N-GT composite catalysts demonstrate significantly enhanced ORR activity and H(2) -air fuel cell performance relative to those of 20%, which is mainly attributed to the intrinsically active N-GT matrix along with possible synergistic effects between the non-precious metal active sites and the Pt nanoparticles.

TL;DR: A cobalt catalyst has been developed for the acceptorless dehydrogenation of alcohols and applied to synthesize imines from Alcohols and amines, and deuterium labeling studies suggest that the reaction proceeds by an initial reversible alcohol dehydration step involving a cobalt hydride intermediate.
