Fig. 2: Necking and particle detachment during spHm mesocrystal dissolution.

From: Crystal dissolution by particle detachment

Fig. 2

a, b Selected time-lapse TEM images showing the necking process (yellow arrows) and eventual particle detachment (dashed red circles), extracted from Supplementary Movie 5 and 6, respectively. c Schematic of necking and particle detachment process. d The dissolution kinetics for the necks (solid symbol) and particle bodies close to the necks (open symbol) showing the abrupt drop to zero at a neck size ≈ 1 nm. The colors represent five necking events from Supplementary Movies 5 and 6. e Distribution of neck diameters from ex-situ TEM images (top) and minimum neck diameter preceding particle detachment from in-situ TEM experiments. f Dose rate dependent dissolution kinetics of spHm. The colors represent three dose rates.
