ChemPlusChem 5/2015: Potpourri
Crystallin protein nanofibrils obtained from fish eye lenses served as platforms for immobilizing enzymes. Luigi Sasso and Juliet Gerrard also designed the picture on the back cover of this issue based on this research.
Ramon Martinez-Manez has developed a new chalcone-based probe for the chromo-fluorogenic sensing of trications over mono- and divalent cations. The subtle interplay at the phase interface of CuO deposited on copper-doped CeO2 nanospheres provided Hongxiao Yang with an excellent catalyst for CO oxidation at ambient temperature. In the research featured on the front cover Takeo Ito and Kasuhito Tanabe describe the surface modification of silica nanoparticles with phospholipids inside living cells (cover profile).

- Enhancing the Efficiency of Water Oxidation by Boron-Doped BiVO4 under Visible Light: Hole Trapping by BO4 Tetrahedra

Essential impurities: The visible-light photocatalytic activity of BiVO4 towards oxygen generation from water is enhanced by boron doping (see figure). Doping creates an occupied defect level per boron, which is localized and made up of the O 2 p levels of the BO4 tetrahedron. Thus, the BO4 tetrahedra that result from boron doping act as hole traps, and therefore, suppress the recombination of photogenerated electrons and holes.

Unraveling reduction: The mechanism of graphite oxide reduction is resolved by analyzing complex deuterides and hydrides. Reduction leads to the formation of hydroxy groups with simultaneous hydrogenation of reduced carbon atoms (see figure).

Quick cleanup! When a melamine sponge was coated with polyaniline and then immersed in n-dodecylthiol, it became superhydrophobic and suitable for oil absorption (see picture). The modified sponge absorbs a broad spectrum of oil and organics efficiently with high absorption capacity, and exhibits thermal stability and excellent mechanical stability.

Energy storage and conversion: Carbon nanofibers (CNFs) have been used as a support for Pd nanoparticles and were applied as air electrodes for alkaline metal–air batteries. Their performance toward the oxygen reduction reaction and the oxygen evolution reaction were investigated. CNFs prove to be promising materials for these applications given their highly graphitic structure, which is responsible for the better stability of these materials compared with commercial supports.

Ultrafine Cu2NiSnS4 nanotubes with an average diameter of 4 nm have been synthesized through a simple strategy using a nanoconfined solvothermal solution within anodic aluminum oxide pores. The as-prepared nanotubes have a preferential growth direction of <100> (see figure).
