In situ etching of AAC silica monitored by liquid cell (S)TEM. (A) Time evolution of the size of AAC spheres in pure water under different electron dose rates. The size evolution of the same experiments as a function of the cumulative electron dose is shown in (B). (C) Time evolution of the size of AAC spheres in a 100 mM NaOH aqueous solution under different electron dose rates. The size evolution of the same experiments as a function of the cumulative dose is shown in (D). Every electron dose rate for each panel contains data of 4 to 5 different nanoparticles. The flow rate was 5 μL.min–1 in all experiments.
