Operando Electrochemical TEM, ex-situ SEM and Atomistic Modeling Studies of MnS dissolution and its role in Triggering Pitting Corrosion in 304L Stainless Steel

By

Researchers at University of Virginia used operando TEM to study pitting corrosion in stainless steel. Using a Protochips #PoseidonSelect they performed liquid-TEM studies during applied potentiodynamic polarization and observed the dissolution of MnS in inclusions in a lamella of 304L stainless steel. Read their paper published in Corrosion Science here: https://lnkd.in/g5yUxGwv. Danyil Kovalov Christopher Taylor … Read More

New E-chip: FIB-optimized E-chip for Poseidon Electrochemistry

By

In research areas where portions of bulk material are the desired sample for in situ TEM analysis, our new FIB-optimized Poseidon Electrochemistry E-chip is the perfect sample support for these types of experiments. FIB lamella preparation on its own, without considering in situ TEM, is challenging to say the least. We want to ensure that … Read More

3 Reasons to Use In Situ Liquid Cell TEM Holders

By

Studying liquid samples under a transmission electron microscope (TEM) has historically been a challenge for researchers. While TEMs are highly useful for capturing fine details in dry, isolated conditions, the high-vacuum conditions in the microscope prohibit liquid environments. This presents a problem for researchers, since studying samples in their native liquid environments holds countless benefits; … Read More

Improved Electrochemistry E-chips

By

Better Electrical Stability To maximize electrical performance, the environment surrounding the reference electrode should be static and free from gaseous byproducts often created during electrochemical sweeping. By isolating the reference electrode away from the most active area surrounding the working and counter electrodes, this design greatly improves electrical stability. Conduct sequential cyclic voltammetry experiments again … Read More
