| Abstract Scope |
The high configurational entropy concept has seen significant inroads in applications areas such as strengthening structural materials such as alloys and ceramics. However, the concept poses a grand challenge in realizing equimolar composition in many emerging materials systems as the thermodynamics of the low-temperature phase does not favor composition homogeneity. In this talk, I will specifically talk about how to overcome the aforementioned challenge and demonstrate that it is possible to use single-atom anchor sites as structural units to assemble concentration-complex single-atom catalyst materials with up to 12 different elements. I will also talk about how to utilize the “high entropy” concept correctly in ceramic battery electrode materials to enable breakthrough electrochemical performances.
