Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

Advanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

Deep Sea Mining for Unique Biocatalysts

Chemistry & Biology, 2005
In this issue of Chemistry and Biology, Ferrer and coworkers describe the discovery of five esterases from a distinct deep sea hypersaline biotope. Interestingly, one enzyme has two unique features-it contains three active centers mediating distinct esterolytic activities, and its tertiary/quaternary structure can be modulated by environmental changes.
