Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

Advanced Science, Volume 13, Issue 11, 23 February 2026.
Synthesis of compositionally‐complex materials is limited by immiscibility of elements. Nonequilibrium synthesis methods reviewed here use ultrafast heating and cooling to overcome this limitation, creating metastable solid solutions and high‐entropy nanomaterials.
