In Situ Liquid Cell TEM Holder for Characterizing Dynamic Behavior of Materials in Liquid Environments
Abstract
This proposal is for the acquisition of an in situ liquid cell specimen holder to enable transmissionelectron microscopy (TEM) in liquid or gaseous environments. TEM is the primary method forobserving structure and chemistry of materials at the atomic scale, but conventional TEM requiresa vacuum environment. The in situ liquid cell holder proposed for purchase (the Poseidon Selectmodel manufactured by Protochips, Inc.) features a liquid layer encapsulated by electrontransparentwindows, and it allows for the observation of materials behavior in liquids that can becontrollably flowed through the chamber. It also features electrical biasing and heatingcapabilities, which enable the investigation of electrochemical phenomena and materials synthesisin the liquid phase. This in situ holder is the final piece that is needed to complete Georgia Tech’sin situ TEM suite, which features multiple novel imaging and data processing modalities inconjunction with other in situ holders that allow for electrical biasing, heating, and mechanicaldeformation in vacuum environments.
