In situ TEM studies of relaxation dynamics and crystal nucleation in thin film nanoglasses

December 19, 2023

Tuesday publication update! In this recent publication, the #FusionAX system was used to directly observe crystallization processes at glass-glass interfaces in sputtered CuZr thin film nanoglasses. The authors utilizing in situ heating experiments combined with other interesting techniques such as nanobeam diffraction patterns (NBDP) and electron correlation microscopy (ECM). This powerful combination allowed them to … Read More

Asymmetric nanoparticle oxidation observed in-situ by the evolution of diffraction contrast

December 12, 2023

By Nynke Krans

Tuesday publication update! Are you interested in structural compositional changes during dynamic behaviors? The following article has researched just this! In this latest work in-situ TEM experiments using the #FusionAX system have uncovered the oxidation from wüstite-magnetite (FeO@Fe3O4) core-shell nanoparticles to single crystalline magnetite, Fe3O4 nanoparticles. Using the ‘Ashby-Brown contrast,’ the structural changes of these … Read More
