title: Tracking of photochemical Ostwald ripening of nanoparticles through voltammetric atom counting.
abstract: We report the tracking of atom count in individual nanoparticles during photochemical Ostwald ripening. The nano-impact technique, in conjunction with UV-Vis and TEM analysis, is used to follow the photochemical formation of silver nano-prisms from spherical seed particles. A mechanism of photochemical Ostwald ripening is deduced and key growth stages are identified.
