Back Cover: Proton Traffic Jam: Effect of Nanoconfinement and Acid Concentration on Proton Hopping Mechanism (Angew. Chem. Int. Ed. 48/2021)

Protons confined within nonionic reverse micelles experience a “traffic jam” in which forward proton hopping, or the Grotthuss mechanism, is restricted. This effect is size- and concentration-dependent: Protons in small micelles or at lower concentrations diffuse freely via forward hopping. For larger sizes or higher concentrations, ions accumulate at the interfacial region of the micelle, causing a gridlock that decreases available pathways for...
