Molecular Electrocatalysis Coupled With a Palladium Membrane Reactor Affords Selective Nitrogen Reduction

Advanced Science, EarlyView.
A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially

Multidimensionally Programming Photoswitching via Orthogonal Covalent‐Noncovalent Chemistry for Dual‐Track Time‐Resolved Optical Encryption

Advanced Science, EarlyView.
A dual‐track time‐resolved encryption strategy with independent information display during photo‐bleaching and thermal‐recovery stages has been realized through multiple temporal encoding units derived from orthogonal covalent‐noncovalent programming of donor–acceptor Stenhouse adduct photoswitching.
