TL;DR: A comprehensive review of recent advances in the field of oxygen reduction electrocatalysis utilizing nonprecious metal catalysts is presented and suggestions and direction for future research to develop and understand NPM catalysts with enhanced ORR activity are provided.

TL;DR: It is revealed that protected sites adjacent to iron nanoparticles are responsible for the observed activity and stability of the catalyst, which may allow for the design and synthesis of enhanced non-precious metal oxygen reduction catalysts with a higher density of active sites.

TL;DR: This work demonstrates the generation of water-in-water (w/w) jets and emulsions by combining droplet microfluidics and aqueous two-phase systems (ATPS) and characterize the encapsulation ability of w/w emulsion and demonstrates that their encapsulation efficiency can be significantly enhanced by inducing formation of precipitates and gels at the w/W interfaces.

TL;DR: In this paper, the authors conducted a kinetic isotope effect (KIE) study in an effort to identify the rate-determining step (RDS) of these intricate electrocatalytic reactions involving multiple protoncoupled electron transfer (PCET) processes.

TL;DR: A kinetic isotope effect (KIE) study is conducted to identify the rate-determining step (RDS) of this intricate electrocatalytic reaction involving multiple proton-coupled electron transfer processes and suggests that the design of future NPM catalysts must include careful consideration of the role of protons during ORR.
