    Laser patterning of liquid-crystal elastomers

    Lack of local phase patterning in liquid-crystal elastomers has hindered their broad implementation. The authors report a laser-induced dynamic crosslinking approach with allyl sulfide groups to achieve reconfigurable high-resolution patterning of multiple liquid crystalline phases in a single film.

    Strain-induced electrocaloric

    Electrocaloric effects are large in a limited set of materials that display hysteretic first-order phase transitions. Here epitaxial SrTiO3 thin films are strain engineered to achieve anhysteretic second-order phase transitions, with electrocaloric effects enhanced by one order of magnitude over bulk.

    Deep-blue OLEDs shine

    Suppressed Dexter transfer is needed to achieve efficient and stable hyperfluorescence, but complex matrices must be involved. A molecular design strategy has been proposed where Dexter transfer can be substantially reduced by an encapsulated terminal emitter, leading to ‘matrix-free’ hyperfluorescence.

    Growing tunable moirés

    Two-dimensional structures with tunable moiré patterns, which display tunable interlayer excitons and moiré intralayer excitons, are achieved by epitaxial bottom-up growth.

    Precise control of gas transport in metal–organic framework glasses

    Porosity of zeolitic imidazolate frameworks can be preserved beyond the glass transition and melt processing. Here centimetre-scale porous glasses are demonstrated, while liquid processing enables fine-tuning of the size of the gas-transporting channels for molecular sieving.

    Magnetoelectric metamaterials for neurostimulation

    Self-rectifying magnetoelectric metamaterials with nonlinear responses generate electrical pulse sequences that enable precisely timed remote neural stimulation and restoration of sensory motor responses in vivo.
