Carbon nanofiber growth rates on NiCu catalysts: quantitative coupling of macroscopic and nanoscale in situ studies

Tuesday publication update! In this newest research written by @TomWelling, the #AtmosphereAX system was used to track carbon nanofiber growth from NiCu-catalyzed methane decomposition under true working conditions. By directly comparing real-time overall carbon growth rates in a reactor (measured gravimetrically) with nanometer-scale carbon growth observations (by electron microscopy), the ex-situ and in-situ results can … 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

Attachment of iron oxide nanoparticles to carbon nanofibers studies by in situ liquid phase transmission electron microscopy

In this publication from the #UniversityUtrecht and #UniversitéeParisCité the authors have looked at the fabrication of Fischer-Tropsch catalysts using the #PoseidonAX system. Iron oxide nanoparticles were flown through the tubings of the liquid cell holder and then subsequently attached to carbon nanofibers. The differences between oxidized and pristine carbon nanofibers was investigated, and it was … Read More
