Direct in-situ imaging of electrochemical corrosion of Pd-Pt core-shell electrocatalysts

August 6, 2024

Tuesday publication update! This new publication in #NatureCommunications from @Jianbo Wu, @Xiaoqing Pan and @Wenpei Gao looks at the corrosion of electrocatalysts during electrochemical operations using the #PoseidonAX. Using electrochemical liquid cell transmission electron microscopy the authors have captured the intricate electrochemical corrosion of Pd@Pt core-shell octahedral nanoparticles, observing their transformation into Pt nanoframes. ⚡ … Read More

Goethite mineral dissolution to probe the chemistry of radiolytic water in liquid-phase transmission electron microscopy

September 19, 2023

By Nynke Krans

In this recent publication, the authors have used liquid phase electron microscopy to observe the dynamic behavior of geothite during dissolution under the irradiation of the electron beam. Kinetic simulations of the different radiolysis species provides insight into the redox and acidity of the liquid during the exposure to the beam. These interactions are very … Read More

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

June 13, 2022

By Kong Lor

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.
