The chemical reactions occurring at the surface of nanoscale catalysts can drastically alter the performance and reliability of those catalysts. With in situ microscopy, you can change environmental conditions of these reactions and directly observe the chemical, structural, and morphological changes underpinning the catalysis reaction with atom-by-atom precision.

This real-time video shows two gold nanoparticles that are on the surface of larger iron oxide particles at 900° C. At this temperature the gold is very mobile, and the two particles coalesce into one larger nanoparticle. This demonstrates the stability of the Protochips Fusion system at high temperatures. This video was taken on a JEOL ARM200F (200 kV, Cs aberration correction) at JEOL in Akishima, Japan. For more information on Fusion, visit www.protochips.com/fusion
