| Outline of Annual Research Achievements |
The concept of ultra-severe plastic deformation was employed in this project to produce high-entropy materials with advanced functional properties. The highlighted achievements of this study can be summarized as follows. (i) We produce a high-entropy alloy with excellent biocompatibility and higher strength compared to conventional Ti-based biomaterials [Mater. Sci. Eng. C, 2020]. (ii) We produced high-entropy hydrides that could reversibly store hydrogen at room temperature with fast kinetics and without need to activation [Scr. Mater., 2020 & Int. J. Hydrogen Energy, 2020]. (iii) We produced the first high-entropy oxide photocatalyst for photocatalytic hydrogen production from water splitting. Our studies confirm the high potential of high-entropy materials for functional applications.
