The electric field created at an electrode–electrolyte interface can polarize the electrode’s surface and nearby molecules. Although its effect can be countered by an applied potential, quantifying the value of this potential is difficult. An optical method for determining the potential of zero charge at an electrochemical interface is now presented.
This work reports on the synthesis and proximity-induced superconductivity in a topological insulator-based, thin-film heterostructure towards the development of a scalable material platform that could potentially support robust quantum computing.
The authors report spin current generation in a metallic layer adjacent to a non-magnetic chiral hybrid organic–inorganic perovskite when subjected to a thermal gradient, and attribute this to chiral phonons possessing angular momentum.

Molecular graphene nanoribbons hold promise for quantum experiments in single-electron transistors but require improvements in their debundling. Here, the authors demonstrate ultra-clean transport devices by enhancing nanoribbon solubility via bulky groups on the nanoribbon edges.
A nanoparticle-based adjuvant incorporating a Toll-like receptor 7 agonist elicits cross-reactive antibodies for both dominant and subdominant epitopes and enhances immune responses against multiple variants of influenza and SARS-CoV-2.
The study of the inherent charge transport behaviour of 3D lead halide perovskite is challenging, owing to entanglement with ionic migration effects and dipolar disorder instabilities. Here, the authors circumvented both challenges and found that ion migration is much suppressed in mixed metal perovskite compositions relative to pure-Pb counterparts.
The high energy densities of Li-rich cathodes are promising for Li-ion batteries, but voltage hysteresis limits their practical implementation. Voltage hysteresis is shown to be related to collective migration of metal ions, and isolating migration leads to high-capacity reversible cathodes.
On-demand electron wavefront shaping is desirable for applications from nanolithography to imaging. Here, the authors present tunable photon-induced spatial modulation of electrons through their interaction with externally controlled surface plasmon polaritons.
High-Ni-content layered cathodes are promising for lithium-ion batteries, but investigating their delithiation-induced phase boundaries is challenging. Intralayer transition motifs at complex phase boundaries in these high-Ni electrodes are now resolved using deep-learning-aided super-resolution electron microscopy.
The authors study the electronic structure of the intercalated transition metal dichalcogenide V1/3NbS2, showing that its bulk magnetism can lead to a strong tunability of spin–valley locked states at its surface.
The authors present evidence suggesting that amorphous Bi2Se3 displays topological properties, signalling a new regime for the pursuit of topological matter.
The authors study ultrafast spatiotemporal dynamics of polaritons formed by mixing surface-bound optical waves with excitons observing a mobility transition from diffusive to ballistic transport flow at two-thirds the speed of light.
Silicon-based complementary metal-oxide semiconductors or negative differential resistance device circuits can emulate neural features, yet are complicated to fabricate and not biocompatible. Here, the authors report an ion-modulated antiambipolarity in mixed ion–electron conducting polymers demonstrating capability of sensing, spiking, emulating the most critical biological neural features, and stimulating biological nerves in vivo.
The realization of strongly correlated bosons in a solid-state lattice is challenging. Here, the authors trap interlayer excitons in an angle-aligned WS2/bilayer WSe2/WS2 multilayer moiré lattice and observe correlated insulating states.
