In this issue, Wenchuan Lai et al. review the role of water in electrocatalysis. Sofiia Zuieva and Xin Chen discuss synthetic approaches to connect molecules and 2D transition metal dichalcogenide in heterostructures in a Minireview.

In the original research section, Qingyu Yan et al. show how to enable an unconventional alternating distal N₂ reduction pathway for the efficient electrosynthesis of ammonia. Jana Roithová et al. mapped the catalytic cycle of Ru-catalyzed ammonia oxidation. Rosalie K. Hocking et al. directly observed the electron donation onto the reactants and a transient poisoning mechanism during CO₂ electroreduction on Ni single-atom catalysts. Bernardo de Souza presents a global optimization algorithm for molecules and atomic clusters. Wei Zhang et al. describe the chiral communication between enantiomeric sergeants and achiral soldiers in racemic triblock copolymers with heterochiral cores for triggering multiple helicity inversions (see picture).
