Lead institution for the study; designed the precursor molecules and ran the characterization
Chemists at the University of Warwick and the University of Birmingham found that materials which briefly form during heating can have useful properties of their own. The team captured a new form of bismuth vanadate, a compound studied for solar hydrogen production, with a different atomic structure and a larger band gap than any known version.
