| Open AccessN-formyl-stabilizing quasi-catalytic species afford rapid and selective solvent-free amination of biomass-derived feedstocks
Processes for efficient production of primary, secondary or ternary aminated compounds are constant challenges for chemical and pharmaceutical industries. Here, the authors develop selective and sustainable amination chemistry widely applicable to chemical substrates via formic acid.

| Open AccessEdge-terminated molybdenum disulfide with a 9.4-Å interlayer spacing for electrochemical hydrogen production
Layered molybdenum disulfide is a promising hydrogen evolution catalyst. Here, the authors report a strategy for synthesizing molybdenum disulfide nanosheets with edge-terminated structure and a significantly expanded interlayer spacing and demonstrate their enhanced catalytic activity.

| Open AccessCoupling artificial molecular spin states by photon-assisted tunnelling
Tunnelling transitions triggered by microwave irradiation between coupled quantum dots have generally been assumed to be spin-conserving. This study shows that this condition is violated in the presence of spin–orbit coupling, thus opening new possibilities for manipulating a two–spin qubit system by microwave irradiation.
