    Glucose is a promising feedstock for hydrogen production but the existing microbial reactors are expensive and suffer from low efficiencies. Here, the authors show an improved self-powered liquid catalyst fuel cell with a polymer-exchange membrane and polyoxometalate to catalyse glucose to hydrogen.

    Liquid organic hydrogen carriers such as N-heterocyclic compounds are interesting hydrogen vectors which could exploit existing infrastructure. Here, the authors report a mesoporous palladium-alumina catalyst system capable of dehydrogenating four different N-heterocycles with negligible activity loss over five runs.

    Trifluoromethyl diazomethane is a versatile reagent with a variety of applications. Here its 1,3-dipolar cycloaddition across internal and terminal alkynes is shown to provide an efficient route to trifluoromethyl-substituted pyrazoles, including derivatives of marketed drugs, natural products, and bioactive heterocycles.

    Capacity fading and electrochemical polarization pose barriers to the commercial use of lithium-sulfur batteries. Here the authors show improved charge polarization and electrochemical performance in a surface oxidized quantum-dot-size titanium nitride embedded within a highly ordered mesoporous carbon matrix.

    Bipyridine derivatives have been shown to control the self-assembly of amyloid-derived dipeptides. Here the authors show that 4,4'-bipyridine inhibits the formation of amyloid-like beta-sheet assembly by Fmoc-protected diphenylalanine, prompting a reorganisation to helical structure, and characterise the transition pathway.

    Designing systems to drive endergonic reactions using light as an energy source is a major challenge. Here a photoswitchable ligand is used to generate unstable cyclic tetravanadate species in solution.

    The photomagnetic switching of metal-free liquid-crystalline materials can be important in material design but achieving reversibility is a challenge. Here the authors show phase transition directly from a chiral smectic phase to an isotropic liquid phase triggered by three different external stimuli.

    Photoluminescent quantum dots are an important technology but can exhibit undesirable intermittent quenching of the photoluminescence. Here, a combination of NMR techniques with XPS and simulations are used to describe the surface coverage of ligands on CdSe nanoparticles and to relate the blinking dynamics to the local dielectric environment.

    Functional multilayer coatings are typically obtained by layer-by-layer deposition of desired molecules. Here spin-coating a solution of chitosan-surfactant vesicles onto silica provides a one-step method to obtain stable multilayer surface coatings with tunable thickness.
