Tuesday publication post! 📖 In this recent publication from the Université Paris Cité, authors Syrine Krouna, Anissa Acheche, Guillaume Wang, Nathaly Ortiz Pena, Riccardo Gatti, Christian Ricolleau, Hakim Amara, Jaysen Nelayah and Damien Alloyeau used in situ aberration-corrected STEM with the #AtmosphereAX to directly observe atomic-scale evolution during heating!
What did they find?
🔥 Real-time observation of AuCoCuNiPt nanoparticle transformations from 298 to 973 K.
💠 Unexpected phase separation: Formation and melting of an AuCu-rich surface layer at high temperatures.
⚛️ Surprising atomic diffusion: More active in these high-entropy alloys than in monometallic or bimetallic systems.
Using in situ microscopy, the authors were able to observe real time, nanoscale reactions with high-entropy nanoalloys, gaining relevant knowledge on nanomaterials behavior at elevated temperatures!
