In this issue, J. P. Barham et al. review the status of synthetic molecular photoelectrochemistry. What new synthetic applications and mechanical insights are there? C. Yu et al. discuss dendritic mesoporous nanoparticles in a further Review. The Minireview deals with the electrochemical synthesis of nitric acid from nitrogen oxidation (B. Zhang).

In the original research section, A. Studer et al. describe a radical 1-fluorosulfonyl-2-alkynylation of unactivated alkenes (see picture). H. Mayr et al. point out an overlooked pathway in 1,3-dipolar cycloadditions of diazoalkanes with enamines. J. Zhou et al. provide structural insights into the catalytic mechanism of the endoperoxide synthase FtmOx1. A. Krȩżel et al. report on structures of silver fingers and a pathway to their genotoxicity.
