In this issue, P. R. Unwin et al. review the electrochemistry of nanoparticles. How did recent advances in experimental approaches enhance the fundamental understanding of electrocatalysis and nanoscale electrochemistry? J. Paradies discusses metal-free hydrogenation of unsaturated hydrocarbons in a Minireview. The Highlight deals with divalent lanthanides and uranium (G. Meyer).
In the Communications section, P. Zelany et al. show how ozonated graphene oxide films can act as proton-exchange membranes (see picture). A. K. M. A. Islam et al. present a superconducting double perovskite bismuth oxide prepared by a hydrothermal reaction at low temperature. S. M. Rummelt and A. Fürstner succeeded in the ruthenium-catalyzed trans-selective hydrostannation of alkynes, and A. M. Rijs et al. revealed gas-phase peptide structures by far-IR spectroscopy combining ion-dip experiments with molecular dynamics simulations.
