Under DAPHNE4NFDI, the X-ray absorption spectroscopy (XAS) reference database, RefXAS, has been set up. For this purpose, we developed a method to enable users to submit a raw dataset, with its associated metadata, via a dedicated website for inclusi

Low activity and a short lifetime are the main weaknesses of photocatalysts. The photoactivity of copper oxide, which is known as one of the most promising materials for H2 evolution and CO2 reduction, can be improved by coupling with other semicondu

Contrary to other semiconductor alloys, incorporation of Ag into CuGaSe2 increases the bandgap, even though the lattice expands, and the Ga–Se bond length is theoretically predicted to decrease rather than increase. Herein, we experimentally confir

Abstract Polyanion‐type phosphate materials, such as M3V2(PO4)3 (M = Li/Na/K), are promising as insertion‐type negative electrodes for monovalent‐ion batteries including Li/Na/K‐ion batteries (lithium‐ion batteries (LIBs), sodium‐ion batt
