    Despite the rapid progress on perovskite light emitting diodes (PeLEDs), the efficiency of blue PeLEDs is lagging behind. Here Wang et al. employ yttrium (III) chloride additive to yield enhanced photoluminescence in the perovskite materials and thus record high device efficiencies for sky-blue and blue PeLEDs.

    Though electret materials are attractive for realizing flexible mechanoelectrical devices, these materials are typically solid films. Here, the authors report stretchable ‘liquid-electret’ devices consisting solvent-free liquid porphyrins that show piezoelectric and electroacoustic functionality.

    The vanadium redox flow battery is promising for commercial applications, but is hampered by high-cost electrolytes that are typically prepared via electrolysis. Here the authors demonstrate cost-effective chemical production of a high-quality vanadium electrolyte using platinum nanoparticles as a catalyst.

    Figures of merit are used to evaluate output performance of triboelectric nanogenerators, but do not account for the breakdown effect that inhibits maximum output. Here the authors propose a standardized assessment method for output capability of nanogenerators that takes breakdown limits into consideration.

    Porous coordination polymers that possess structural flexibility show great promise for gas adsorption and catalysis. Here the authors synthesize a dynamic porous coordination polymer with rotating ligands that permit effective CO2 trapping, and demonstrate subsequent CO2 cycloaddition to epoxides.
