CT08 Mechanochemical Coupling in Chemical Treatment and Materials Degradation—Modeling and Experimentation
This symposium aims at the fundamental and cross-disciplinary understanding of mechano-chemical coupling (MCC) in chemical or electrochemical processes. This coupling is of great importance to everyday life and modern industry. For example, it affects the cyclability of rechargeable batteries, the impact resistance of screen cover glass, and the durability of materials in high-temperature and corrosive environments. Analytical, computational, and experimental tools have been developed discretely for each situation to comprehend, mitigate, or make use of these coupling effects, but rarely is this expertise leveraged between research areas. New cross-disciplinary interactions could therefore bring about a broad impact on MCC research. The symposium also aims to foster the synergy between theoretical and experimental investigations. Theoretical and computational models lay the groundwork for comprehending and predicting MCC in materials processing or degradation. Experimental studies complement modeling with quantitative unveiling of the coupling phenomena, such as the in-situ observations of oxidation or lithiation, and the atomic-resolution imaging of diffusion/reaction processes. Discussions of materials synthesis and fabrication methods based on MCC and discussions that advance understanding of fundamental material science issues are also welcomed. To promote cross-disciplinary discussion under the theme of MCC, we call for abstracts in, but not limited to, the following areas: mechano-chemical modeling of diffusion and reaction in multi-component systems, the degradation of bulk or thin-film materials at high temperatures and/or corrosive environments, new battery concepts that mitigate the MCC effect (e.g., Zero-Strain cathode materials), ion-exchange process in glass and polymers, and advanced energy materials.
