Direct Visualization of Temperature‐Induced Phase Separation of Completely Miscible Au─Pd Alloy by In Situ TEM (Small 19/2025)
Source abstract
Abstract
Au@Pd Nanostructures In article number 2408109, Abhijit Roy, Simon Hettler, and Raul Arenal investigated the behavior of Au@Pd nanostructures under in-situ TEM heating, revealing the remarkable and unexpected phase separation of Au and Pd. These elements are considered fully miscible across all temperatures and compositions. However, this direct observation of their phase separation - previously only theorized - challenges conventional alloy stability concepts at the nanoscale.
