Impact of palladium/palladium hydride conversion on electrochemical CO2 reduction via in-situ transmission electron microscopy and diffraction

An additional Friday publication update! Congratulations on a great #NatureCommunications from authors @Ahmed Abdellah of the group of @Leyla Soleymani and @Drew Higgins! In this newest publication, they showed how to remarkably do #diffraction at operando level during in situ electrochemistry. They used the #PoseidonAX system to look at Pd-based catalysts for the CO2 conversion … Read More

Degratation Mechanisms of Supported Pt Nanocatalysts in Proton Exchange Membrane Fuel Cells: An Operando Study through Liquid Cell Transmission Electron Microscopy

In this publication, the authors have researched a typical platinum fuel cell at nanometer scale, using the #PoseidonAX system with electrochemistry. The 3 nm platinum on carbon particles were observed after a large amount of CV cycles in which the particles grew over time. The growth was followed using in situ liquid phase electron microscopy. … Read More

Metal Monolayers on Command: Underpotential Deposition at Nanocrystal Surfaces: A Quantitative Operando Electrochemical Transmission Electron Microscopy Study

Are you interested in combing #LiquidEM and #Xrayspectroscopy? Authors from #UniversityofBerkley have recently published some beautiful results in #JACS on Cu nanocatalysts for CO2 electroreduction. Using a #PoseidonSelect in their beamline set-up for small-angle x-ray scattering, the researchers were able to investigate the chemical environment and interparticle information on nanocatalysts.
