In situ
TEM utilizing specialized holders and
MEMS chips allows the investigation of the interaction, evolution,
property, and function of nanostructures and devices responding to
designed environments and/or stimuli. This mini-review summarizes
the recent progress of
in situ
TEM with a liquid
cell and a flow channel for the investigation of interactions among
aqueous nanoparticles, electrolytes, and electrodes under the influence
of electric bias and electron beam. A focus is made on nanoparticle
growth by electrodeposition, particle nucleation induced by electric
biasing or electron beam, self-assembly, and electrolyte breakdown.
We also outline some future opportunities of
in situ
TEM with aqueous cells and flow.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
