  • Self-healing behaviour in a nanotwinned diamond composite, at room temperature, has been quantitatively evaluated through tensile testing. The phenomenon is shown to arise from a transition of atomic interactions from repulsion to attraction and the formation of nanoscale diamond ‘osteoblasts’, in analogy to the process of bone healing in living organisms.

  • Polyethylene terephthalate (PET) tape is widely used for lithium-ion batteries but its chemical stability has been largely overlooked. Reversible self-discharge is now shown to be virtually eliminated in LiFePO4–graphite cells by replacing PET with polypropylene jellyroll tape.

  • The room-temperature self-healing behaviour of a nanotwinned diamond composite is quantitatively evaluated and found to stem from both the formation of nanoscale diamond osteoblasts and the atomic interaction transition from repulsion to attraction.

  • Unit-cell-thick films of metal–organic frameworks with ordered porosity would be attractive for membrane applications as these thin systems combine large molecular flux with high selectivity. Here crystalline ZIF films are grown on a crystalline substrate with high H2/N2 gas separation performance.

  • Trapped films of air known as plastrons are promising for underwater engineering but typically have short lifetimes. Here, aerophilic titanium alloy surfaces are developed with thermodynamically stabilized plastrons for antifouling applications.

  • Dynamic disorder reduces the carrier mobility in organic semiconductors (OSs) to an extent that depends on their specific electronic band structure. Here the authors study the temperature-dependent hole mobility of two structurally similar OSs and find that thermal access to transiently delocalized states enhances hole mobility in C8-DNTT-C8 compared to DNTT.

  • The rational design of out-of-equilibrium demixing transitions remains challenging. Active fluids are used to control the liquid–liquid phase separation of passive DNA nanostars and establish the activity-based control of the phase diagram.

  • Organic luminophores emit a bright near-infrared afterglow after X-ray irradiation and outperform commercially available radio sensitizers by producing higher levels of singlet oxygen, having potential applications in precision cancer theranostics.

  • Inspired by valley pseudospins in two-dimensional materials, high-quality-factor (high-Q) spin–valley states were created through the photonic Rashba-type spin splitting of a bound state in the continuum. This approach enabled the construction of a coherent and controllable spin-optical laser using monolayer-integrated spin–valley microcavities without requiring magnetic fields or cryogenic temperatures.

  • By optimizing the molecular organization of blue-emitting organic semiconductors, the vulnerability of the materials to extrinsic impurities that cause charge trapping, such as oxygen and water, is strongly reduced. Steric shielding of the electron-transporting core is shown to increase the electron transport by several orders of magnitude.

  • Peer review has long been established as the gold standard for scientific publishing, but changes in the publishing ecosystem should not influence author response to the views of their peers.

  • Amorphization can be an additional mechanism to assist plastic deformation in crystalline materials, providing a strategy to improve the load-bearing ability of brittle materials.
