Identifying carbon as the source of visible single-photon emission from hexagonal boron nitride

by Noah Mendelson

Nature Materials, Published online: 02 November 2020; doi:10.1038/s41563-020-00850-y

The role of adsorbed hydroxide in hydrogen evolution reaction kinetics on modified platinum

by Ian T. McCrum

Nature Energy, Published online: 19 October 2020; doi:10.1038/s41560-020-00710-8

The appropriate descriptors for a catalyst’s hydrogen evolution activity in alkaline electrolyte are debated. Combining simulations and single-crystal studies of metal-decorated Pt surfaces, McCrum and Koper show that activity exhibits a volcano-type relationship with the hydroxide binding strength of the catalyst, providing a target for catalyst design.

Long-range ordered and atomic-scale control of graphene hybridization by photocycloaddition

by Miao Yu

Nature Chemistry, Published online: 19 October 2020; doi:10.1038/s41557-020-0540-2

The controllable functionalization of graphene at the molecular level may prove useful for graphene-based electronics, but is difficult to do in a precise fashion. Now it has been shown that a photocycloaddition reaction between a hydrogen-bonded network of maleimide-derived molecules and single-layer graphene can produce a functionalized array with long-range order.

Nature Physics, Published online: 05 October 2020; doi:10.1038/s41567-020-1028-0

Scale-invariant magnetic anisotropy in RuCl3 has been revealed through measurements of its magnetotropic coefficient, providing evidence for a high degree of exchange frustration that favours the formation of a spin liquid state.
