In this issue, R. Martin et al. review transition-metal-catalyzed carboxylation reactions with carbon dioxide. Does CO₂ as C₁ feedstock mean a new era for C–C bond formation? In a Minireview, M. Antonietti et al. discuss photoredox catalytic organic transformations with heterogeneous carbon nitrides.

In the Communications section, S.-J. Hwang et al. describe how to use α-MnO₂ nanowire-anchored highly oxidized clusters as catalysts for Li–O₂ batteries (see picture). A. Mirjafari et al. succeeded in the autocatalytic synthesis of bifluoride ionic liquids by SuFEx click chemistry. J. V. Barth et al. explored interfacial porphine coupling schemes and hybrid systems by bond-resolved scanning probe microscopy, and N. Steunou et al. encapsulated enzymes in mesoporous metal-organic frameworks for selective biodegradation of harmful dye molecules.
