An Fe^III/V redox mechanism in Li₄FeSbO₆ on delithiation without Fe^IV or oxygen formation with resistance to aging, high operating potential and low voltage hysteresis is demonstrated, with implications for Fe-based high-voltage applications.

Spontaneous scrolling in two-dimensional polar van der Waals materials, driven by intrinsic out-of-plane electric polarization, enables the scalable production of nanoscrolls and their heterostructures.

Time-resolved surface X-ray scattering is used to probe how light manipulates orbital order at the surface of a manganite. Femtosecond light is found to generate incoherent atomic disorder on an ultrafast timescale, consistent with the localization of polarons.

This Review discusses recent advances in afterglow materials for biomedical applications, the distinct imaging modalities that these agents enable and strategies to optimize their properties for improved disease diagnosis and therapies.

Stability issues hinder the commercialization of perovskite solar cells. An evaporated, highly oriented wide-bandgap perovskite film is reported, enabled through an intermediate phase evolution, resulting in enhanced stability and efficiency.

The coexistence of frustrated magnetism and bond order is demonstrated in a family of antiferromagnets. Layers of dual frustrated orders are interleaved in the same crystal lattice, which presents an exciting possibility for engineering new responses.

Determining the feasibility of intergrowths between zeolites is investigated using high-throughput atomistic simulations and experimental verification. Interfacial energy is an effective descriptor for identifying the feasibility of zeolite intergrowths and a zincosilicate zeolite intergrowth with three and nine rings is realized by hydrothermal syntheses.

A domain-folding strategy is developed to assemble graphene into carbon fibres at room temperature, achieving ultrahigh strength and stiffness as well as greatly reducing energy consumption.

Viscoplastic surface effects in polymeric elastomers drive the development of sealing platforms with high hermeticity and large stretchability to safeguard stretchable electronics from degradation.

Garnet-type LLZO electrolytes are considered among the most promising solid-state electrolytes for all-solid-state batteries; however, numerous challenges need to be addressed before they are integrated into a cell. By precipitating amorphous zirconium oxide onto grain boundaries, increased ionic conductivity is observed and dendrite growth is suppressed.

The emergence of lipid nanoparticles as nucleic acid delivery vehicles has revolutionized medicine, with polyethylene glycol (PEG)-lipids playing a crucial role in particle formation and in vivo fate. However, PEG has been linked to immune responses that can provoke side effects and may prevent repeat dosing, and so PEG alternatives are now being developed. Here we argue that, rather than concentrating on PEG replacement, the field should prioritize designing around pre-existing immune memory.

Our knowledge of deformation behaviour in functional materials is pushing the frontiers of mechanics, informing design strategies and enabling scalable manufacturing.

Pioneer of high-pressure physics and superconductivity.

In this issue we present three papers on the topological properties or structure of ferroelectrics, which are interlinked.

Seven years on from updates to our data sharing policies, we reflect on data-deposition-related changes to our published papers and continue to strongly encourage authors to make source data openly available.

The Hall effect has been a powerful probe of the physics of materials for more than a century.
