摘要

Abstract

Metal sublimation plays a crucial role in understanding natural phenomena

purification and advanced manufacturing. Herein

we report anomalous sublimation passivation of nanotwinned silver particles under e-beam irradiation through

in situ

transmission electron microscopy

wherein the sublimation velocity is reduced by three-quarters due to the formation of five-fold twins. Theoretical calculations reveal that this sublimation passivation mechanism is mainly related to the increment in sublimation energy by the presence of twin boundaries.
