Abstract

Silica (SiO2) glass, an essential material in human civilization, possesses excellent formability near its glass-transition temperature (T-g > 1100 degrees C). However, bulk SiO2 glass is very brittle at room temperature. Here we show a surprising brittle-to-ductile transition of SiO2 glass nanofibers at room temperature as its diameter reduces below
