| Abstract Scope |
Significant advancements in ceramic science are required to address emerging societal challenges such as climate change and the need for better energy storage technologies. The necessary breakthroughs will require the reevaluation of existing ceramic design strategies. In this presentation, I will discuss how leveraging the complex chemistry in entropy stabilized oxides (ESOs) allows for unique phase transformations that can be tuned to precisely and reversibly control phase distribution, microstructure, properties, and behavior. I will discuss how chemistry, processing, and microstructure can be used to control the phase transformation and design the microstructure in ESOs. Then I will present examples of how the resulting phase heterogeneity can be used to tune mechanical and functional behavior, with a particular emphasis on applications relating to electronics and energy storage. These examples demonstrate that transformative results can be achieved through strategic use of complex ceramic chemistries and innovative materials processing methods. |
