NSRRC Activity Report 2022

C hemistry is an integral part of our daily lives, occurring everywhere and not just in laboratories. Understanding the nature of chemical reactions is essential for achieving sustainable development and improving our quality of life. This year, the Chemical Science section features five highlighted works covering the development of new materials, insights into reaction mechanisms, and proof of concept for both fundamental and applied chemistry. Ru-Shi Liu investigated the formation mechanism of Li 2 CO 3 in Li–CO 2 batteries using in situ small-angle X-ray scattering. Han-Yi Chen reported a promising cathode material and anodic protection layer for Zinc-ion capacitors with high capacity and excellent stability. Yen-Ju Cheng and U-Ser Jeng used water to align amphiphilic liquid crystals effectively. Chien-Lung Wang and his collaborators developed stable metal halide perovskites with up to 55% reduced lead content using high-entropy alloying. Finally, a novel non- volatile additive via supramolecular interactions improved the efficiency and thermal stability of organic solar cells. In summary, this section highlights significant works that showcase the breadth of chemistry's impact, including Li–CO 2 batteries, Zinc-ion capacitors, amphiphilic liquid crystals, metal halide perovskites, and organic solar cells.
