Replicating bulk electrochemistry experiments in-situ in the TEM

Hummingbird Scientific’s newest Generation V Bulk in-situ liquid-electrochemistry holder allows researchers for the first time to fully replicate bulk-level electrochemical details inside the transmission electron microscope. A newly developed hardware system allows quantitative measurements of electrochemical processes with details showing the complete cycle of the bulk.

As  an illustration, a cyclic voltammetry (CV) study of a model compound CuSO4  solution showing plating and stripping of copper from the active electrode has been presented here. The copper plating and stripping occurs at the  working electrode, replicating actual bulk behavior.

The new Hummingbird Scientific’s liquid-cell hardware and cells allows, for the first time, for replication of bulk-level data in TEM.
