In this issue, C. Hu and L. Dai review carbon-based metal-free catalysts for electrocatalysis. How can they be designed and used in metal–air batteries and for water splitting? In a Minireview, T. Billard et al. discuss synthetic approaches to trifluoromethoxy-substituted compounds. The Highlight deals with the structural basis of bacterial membrane protein inhibition (S. Koppermann and C. Ducho).

In the Communications section, C. Müller et al. click the arsenic–carbon triple bond to enter an new class of arsenic heterocycles (see picture). S. K. Meena and M. Sulpizi report on the microscopic origin of anistropic growth from gold nanoseeds to nanorods. M. T. Reetz et al. show how
