[MIS10-04] Investigation of liquid cell transmission electron microscopy combined with antisolvent crystallization
Keywords:liquid cell transmission electron microscopy, crystal growth, solution growth, anti-solvent crystallization
We used the TEM holder (Poseidon 300, Protochips Inc.) and the liquid cells of silicon chips equipped with thin silicon nitride windows. Aqueous solution of sodium chlorate under equilibrium at room temperature was enclosed in the liquid cell. The TEM holder has two injection ports of liquid, and one of the ports was filled by acetone as the anti-solvent of sodium chlorate. After starting the observation of the sample solution, acetone was injected by syringe pump for mixing the aqueous solution in the liquid cell.
Using the methods, we succeeded in observing the nucleation events of crystals. In this presentation, we will report the detailed analysis of crystals and the nucleation processes.
