Electrocatalysts require a hydrated environment along with electrochemical signals to observe their true behavior at the nanoscale. With Protochips’ machine-vision powered suite of in-situ TEM tools you can utilize the electron microscope as a real-time laboratory to study electrocatalysts at a resolution of a few nanometers. In situ TEM enables the study of the oxygen evolution reaction (OER), carbon dioxide reduction reaction (CO2RR), hydrogen evolution reaction (HER), and other conditions at the nanoscale.

In this application note, written by Protochips, we summarize how in situ electron microscopy using liquid phase is challenged by radiolysis side effects and how to minimize these effects.
In this paper, we take a look at how AXON Dose tracks the electron flux and cumulative dose, and why this might be useful for all experiments.
In this summarized paper, Dr. David Muller’s research group used the Poseidon system to image in situ the degradation mechanisms to understand how to increase the lifetime of fuel cells.
In this paper, written by Protochips, nanometer resolution elemental mapping of nanostructures in solution has been demonstrated using the Poseidon system.
This paper, written by Protochips, summarizes different publications on how to best do EELS and EDS in liquid environments.
In this paper, researchers in Muller’s group showed how to perform EELS during in situ electron microscopy using a Poseidon system.
In this summarized paper, L. Mehdi and N. Browning at the Joint Center for Energy Storage Research at Pacific Northwest National Lab in Richland used the Poseidon system to observe the charging and discharging process of lithium-ion batteries.
