  Spatial separation of photogenerated electrons and holes among {010} and {110} crystal facets of BiVO₄

  Charge separation determines the efficiency of semiconductor-based photocatalysts. Here Li et al. show that, in BiVO4, photogenerated electrons and holes accumulate on different crystal facets and the targeted deposition of cocatalysts increases the efficiency of photocatalytic water oxidation.

  Spectroscopic observation of iodosylarene metalloporphyrin adducts and manganese(V)-oxo porphyrin species in a cytochrome P450 analogue

  Metalloporphyrin compounds are studied as models of cytochrome P450, which is capable of catalysing oxidative reactions. Here, reaction conditions are varied to allow spectroscopic observation of oxidant-metalloporphyrin adducts and metal-oxo intermediates, which may elucidate reaction mechanisms.

  Quasiparticles and Fermi liquid behaviour in an organic metal

  The physical properties of organic metals have generally been described in terms of a highly correlated Luttinger liquid. Using angle-resolved photoelectron spectroscopy, Kisset al. measure the Fermi surface of (BEDT-TTF)₃Br(pBIB), and find that, in contrast to other systems, it can be described as a Fermi liquid.

  A non-syn-gas catalytic route to methanol production

  Methanol is an important industrial chemical and liquid fuel, and is usually produced by the syn-gas route from natural gas. Wuet al. develop a new catalytic process that directly converts ethylene glycol, derived from biomass or fossil fuels, to methanol in hydrogen using a Pd/Fe₂O₃co-precipitated catalyst.

  Dynamic Jahn–Teller effect in the parent insulating state of the molecular superconductor Cs₃C₆₀

  Expanded alkali fullerides are molecular superconductors with a Mott parent insulating state. Kluppet al.use infrared spectroscopy to detect the molecular Jahn–Teller distortion of fulleride ions and establish its relevance to strongly correlated superconductivity.

  Unsupported boron–carbon σ-coordination to platinum as an isolable snapshot of σ-bond activation

  σ-Complexes of transition metals are key intermediates in metal-mediated bond activation, but have traditionally been isolable only when chelating or when one of the participating atoms is hydrogen. Here, a complex is isolated with an unsupported borirene ligand bound not through the unsaturated C=C bond, but exclusively via a B–C single bond.

  Tandem synthesis of alternating polyesters from renewable resources

  Biomass-derived monomers are a renewable resource for the production of polymers. Robertet al. develop an auto-tandem catalytic transformation for the synthesis of aliphatic polyesters—'activated' monomers are prepared from dicarboxylic acids, which can be copolymerized with epoxides.

  Direct stereoselective α-arylation of unmodified enals using an organocatalytic cross-coupling-like reaction

  Cross-coupling reactions are widely used for creating new carbon–carbon bonds in chemical syntheses. Using the cross-coupling concept, Wang and colleagues present an organocatalytic strategy for the direct and stereoselective α-arylation of enals that occurs under mild conditions.

  Structure and compatibility of a magnesium electrolyte with a sulphur cathode

  Magnesium is an ideal rechargeable battery anode material, but coupling it with a low-cost sulphur cathode, requires a non-nucleophilic electrolyte. Kimet al. prepare a non-nucleophilic electrolyte from hexamethyldisilazide magnesium chloride and aluminium trichloride, and show its compatibility with a sulphur cathode.

  Iron-based cathode catalyst with enhanced power density in polymer electrolyte membrane fuel cells

  Replacing platinum in polymer-electrolyte-membrane fuel cells with iron-based catalysts could provide low-cost power generators, but often leads to low power densities. Here, a new iron-based cathode catalyst is developed with enhanced power density, volumetric activity and mass-transport properties.

  A flow-microreactor approach to protecting-group-free synthesis using organolithium compounds

  Protecting-group-free synthesis has received significant attention, but organolithium species react rapidly with ketones necessitating protection of the ketone carbonyl. Here, a flow-microreactor approach is described that allows protecting-group-free organolithium reactions in the presence of ketones.
