The slow turn-on speed in accumulation-mode organic electrochemical transistors is explained by asymmetric ion transport in switching kinetics.

A wide range of zero-dimensional powders can be converted into versatile, high-performance one-dimensional micro-/nanofibres by using two-dimensional cellulose sheets as a mediator, preserving the particles’ nanostructural features and acting as building blocks for complex geometric shapes to satisfy application requirements.

‘Two colour’ pump–probe experiments on yttrium iron garnet discs demonstrate how to harness dissipation of magnetic oscillations. This may have important implications for the use of magnetic materials for information processing.

A synthesis method for large-scale conjugated polymers as well as studies under operational conditions show that research on organic mixed ionic–electronic conductors continues to progress.

Physical vapour deposition of small-molecule glass formers onto soft substrates enhances the local dynamics at the top free surface, leading to the formation of denser glasses and providing access to states deeper in the potential energy landscape.

Strong bulk van der Waals materials can be created from water-mediated densification of two-dimensional nanosheets by near-room-temperature moulding, establishing a pathway for the energy-efficient fabrication of a wide range of bulk van der Waals materials and even composites for various applications.

Modified Suzuki–Miyaura polymerization procedures provide a scalable and reproducible route to regioregular conjugated polymers.

Degradation is one of the most common causes of capacity deterioration in high-energy-density cathodes. Rotational stacking faults in layered lithium transition-metal oxides are shown to play a critical role in determining their structural and electrochemical stabilities.

Efficient phononic nonlinear processes are demonstrated in an acoustoelectric heterostructure combining a high-mobility semiconductor indium gallium arsenide film heterogeneously integrated onto a lithium niobate thin film.

The emergence of chiral morphologies from achiral building blocks is not well understood. Deep learning-based interpretation provides representative models for the process of symmetry breaking and chiral development during the growth of gold nanoparticles.

The thermalization of acoustic phonons after photoexcitation is traced by electron pulses in TiSe₂, and the excitonic contribution to the structural order parameter of the material’s charge density wave phase is quantified.

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.

Adding homogeneously dispersed oxide nanoparticles to aluminium pushes its high-temperature strength up to 500 °C.

Liquid bioelectronics based on a permanent fluidic magnet made from three-dimensional assembled magnetic colloidal particles can be injected into the surface of the heart for cardiovascular monitoring and subsequently retrieved after use.

In a multi-principal-element VCoNi alloy, premature necking during Lüders banding has been harnessed to produce rapid dislocation multiplication, leading to both forest hardening and hardening induced by regions of local chemical order. The result is ductility of 20% and a yield strength of 2 GPa, during room-temperature and cryogenic deformation.

The magnetism-mediated assembly of non-Brownian magnetic colloidal particles into a three-dimensional oriented and ramified magnetic network yields permanent fluidic magnets that are used in a self-powered, liquid-based wireless cardiovascular sensor.

The molten structure of plutonium oxide—a component of mixed oxide nuclear fuels—is measured, showing some degree of covalent bonding. Its atomic structure is similar to that of cerium oxide, which could be a non-radioactive structural surrogate.

Electrode arrays for neurological diagnosis and treatment carry a risk of nerve injury. Nerve cuffs with tiny voltage-controlled shape-reconfigurable electrode arrays have been reported, allowing active wrapping around delicate nerves.

An interface modification strategy has been developed to uniformly distribute high-density sub-10 nm coherent MgO particles in an Al matrix, resulting in high strength and creep resistance at temperatures up to 500 °C.
