In-situ nano-compression of a SiO2 glass nanoparticle - A 500 nm amorphous SiO2 glass particle (top of the image) is plastically deformed into a pancake geometry in a compression test of Hysitron Picoindenter (PI95). The loading rate of 15 nm/s was generated by driving a flat diamond punch (lower left corner). Gatan ORIUS® 830 camera. Movie was captured by Gatan in-situ software.
