  • 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.

  • 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.

  • Conventional iontronic pressure sensors suffer from signal drift and inaccuracy owing to creep of soft materials and ion leakage. Here the authors report a leakage-free and creep-free polyelectrolyte-elastomer-based iontronic sensor that achieves a drift rate two to three orders of magnitude lower than those of conventional iontronic sensors.

  • 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.

  • Cu2Se is of interest for thermoelectrics as it is environmentally sustainable and has a high figure of merit ZT; however, copper ion migration impacts device stability. Here a co-doping strategy that combines steric and electrostatic effects is shown to improve device stability as well as improving ZT to 3.

  • Oxygen redox cathodes deliver higher energy densities than those based on transition metal redox but commonly exhibit voltage fade on extended cycling. The loss of O-redox capacity and voltage fade is shown to arise from a reduction in O2−/O2 redox process reversibility and O2 loss.

  • Solvation dynamics at picosecond timescales critically affect charge transport in aqueous systems, but conflicting values have been reported for organic electrolytes. Lifetimes on the order of 1 ns for mixtures of organic polymer and lithium salt exhibiting ultraslow dynamics of solvation shell break-up are now reported.
