Amplifying enantioselective interactions to the macroscopic scale remains a challenging goal. Here, visible gel pieces assemble enantioselectively as a result of chiral recognition between tryptophan and cyclodextrin monomers.
Tungstate accumulates in bone and can be resistant to chelation therapies typically used to remove heavy metals in vivo. Here, tungstate is shown to accumulate in mouse bone tissue in a persistent, insoluble form proposed to be condensed polytungstate.
Transition state energy correlations are key to the computational search for new catalysts, but are computationally expensive. Here the authors generalize a recent approach based on bond-order conservation arguments and apply it to dehydrogenation reactions on low index metal surfaces
Graphene oxide membranes are promising materials for the separation of low molecular weight gases. Here, composite membranes comprising metal organic frameworks and graphene oxide show improved selectivity for the separation of hydrogen and carbon dioxide over graphene oxide alone.
Imparting both high strength and stretchability in polymers is challenging as it requires changing the crosslinking density of the polymer network. Here, Miwa et al. use an ionic elastomer with dynamic crosslinks to achieve high strength under rapid deformation but high stretchability under slow deformation in a single material.
Metal-organic frameworks are candidates for future energy storage materials, but are limited by poor conductivity and random crystal orientation on current collectors. Here, fabrication of electrodes containing uniformly oriented crystals supported by carbon nanowalls leads to improved electrochemical performance.
