Here, we report a zinc-O 2 /zinc peroxide (ZnO 2) chemistry that proceeds through a 2e − /O 2 process in nonalkaline aqueous electrolytes, which enables highly reversible redox reactions in zinc-air batteries. This ZnO 2 chemistry was made possible by a water-poor and zinc ion (Zn 2+)–rich inner Helmholtz layer on the air cathode caused by ...
Because nitrate reduction is rate-limiting, aryldiazoniums are produced as fleeting intermediates, which results in a safer and often more efficient deaminative halogenation in a single step from anilines. The science of loneliness, making one of organic chemistry’s oldest reactions safer, and a new book series. BY.

Tip-induced selective single-molecule reactions increase our understanding of redox chemistry and could lead to novel molecular machines. A Swiss Army knife for surface chemistry. By Igor Alabugin, Chaowei Hu • Science • 15 Jul 2022. Controlling selectivity in reactions is a central goal in chemistry.
Breaking down microdroplet chemistry. Charged microdroplets are commonly observed in clouds, sea spray, and other natural aerosols. The chemistry that occurs at the air-water interface of these droplets is often distinct from that observed in bulk solution, which is of considerable interest because chemical reactions can be accelerated at this ...
Hartrampf et al. used an automated chemistry platform to optimize fast-flow peptide synthesis and were able to produce fully synthetic single-domain proteins (see the Perspective by Proulx). The targets included proinsulin and enzymes such as barnase and a version of HIV-1 protease containing multiple noncanonical amino acids.

The eponymous acids and bases were codified by Gilbert Lewis in 1923 (1), and in 1952, Robert Mulliken posited that Lewis acids and bases associate through “inner” and “outer” forms (2). Yet, the molecular structures of these two forms of the Lewis adduct have been elusive. On page 1184 of this issue, Liu and Gabbaï (3) report the ...
