In this issue, P. Fratzl et al. review the mechanical role of metal ions in biogenic protein-based materials. How do protein–metal interactions influence properties such as hardness, toughness, adhesion, and self-healing? The Highlights deal with the characterization of nanoporous solids by three complementary techniques (J. M. Thomas and R. K. Leary) and the conversion of CO2 to methane on copper surfaces (M. Behrens).
In the Communications section, M. Sprik et al. describe how to align electronic and protonic energy levels of proton-coupled electron transfer in water oxidation on aqueous titania (see picture). D. P. Fairlie et al. succeeded in making a cyclic heptapeptide orally bioavailable. W.-J. Xiao et al. reveal the photocatalytic generation of N-centered hydrazonyl radicals, and G. R. Newkome et al. report on the fractal design and chemical reality of a self-assembled terpyridine-CdII Sierpinski triangle.
