Tuning Electrodeposition Parameters for Tailored Nanoparticle Size, Shape, and Morphology: An In Situ ec-STEM Investigation
Advances in vacuum-tight in situ liquid cell TEM systems have attracted significant attention because of the ability to directly interpret chemical and electrochemical reactions within their native liquid environments [1]. Conducting quantitative in situ electrochemistry experiments within the S/TEM is feasible using the relatively new platform of in situ electrochemical S/TEM (ec-S/TEM). In th...
متن کاملIn-situ Electrochemical Liquid Cell TEM Visualization of Electrode-Electrolyte Interfaces
We have developed electrochemical liquid cells for transmission electron microscopy (TEM), which allows imaging of electrochemical processes in liquid electrolytes with high spatial resolution in situ (Fig. 1). Using this set up, we study electrochemical deposition and dissolution of lead dendrites on gold electrodes immersed in an aqueous solution of lead nitrate. Observation reveals lead dend...
متن کاملDirect in situ observation of ZnO nucleation and growth via transmission X-ray microscopy.
The nucleation and growth of a nanostructure controls its size and morphology, and ultimately its functional properties. Hence it is crucial to investigate growth mechanisms under relevant growth conditions at the nanometer length scale. Here we image the nucleation and growth of electrodeposited ZnO nanostructures in situ, using a transmission X-ray microscope and specially designed electroche...
متن کاملInvestigating processes of nanocrystal formation and transformation via liquid cell TEM.
Recent ex situ observations of crystallization in both natural and synthetic systems indicate that the classical models of nucleation and growth are inaccurate. However, in situ observations that can provide direct evidence for alternative models have been lacking due to the limited temporal and spatial resolution of experimental techniques that can observe dynamic processes in a bulk solution....
متن کاملIn situ UHV-TEM investigation of the kinetics of initial stages of oxidation on the roughened Cu(1 1 0) surface
The initial stages of oxidation on roughened Cu(1 1 0) surface were explored by an in situ ultra-high vacuum transmission electron microscope (UHV-TEM). The dynamic observation of the nucleation and growth of Cu oxide islands shows a highly enhanced nucleation rate on the roughened Cu(1 1 0) surface. The kinetic data obtained from the initial stages of the oxidation indicate that oxygen surface...
