    Iodide-related defects pose serious challenges to the irradiation, thermal, light or reverse-bias stabilities of perovskite solar cells. Here, the authors find that by using the iodide/polyiodide capture and confine effects of perfluorodecyl iodide interfacing with perovskites, inverted perovskite solar cells achieve much improved stabilities.

    The turn-off time is generally faster than the turn-on time in accumulation mode organic electrochemical transistors (OECTs), but the mechanism is less understood. Here the authors find different transient behaviours of turn-on and turn-off in accumulation mode OECTs, and ion transport is the limiting factor of device kinetics.

    Soft pressure sensors drift under prolonged high stress because of the creep of soft materials, which causes inaccurate measurements. Now, through molecular-level design, a leakage-free and creep-free polyelectrolyte elastomer is synthesized, and an iontronic sensor using the polyelectrolyte elastomer shows very low signal drift under a high static pressure.

    Better control over the quality of materials dissipates doubts about charge order in infinite-layer nickelates and indicates that a previously observed superstructure is probably a spurious effect related to other crystalline phases. This finding strengthens the similarities between nickelates and cuprates.

    Electrocaloric effects have not hitherto been experimentally studied at a phase transition created by strain. It is now shown that the continuous transition created by epitaxial strain in strontium titanate films greatly enhances electrocaloric effects over a wide range of temperatures, including room temperature.

    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.

    Pre-intercalation with alkali-metal ions is attractive for accessing higher reversible capacity and improved rate performance in Li-ion batteries. Topochemical single-crystal transformations in a tunnel-structured positive electrode are used to clarify the effect of pre-intercalation in modifying the host lattice and altering diffusion pathways.
