A new memory device in which the electric dipole, rather than the magnetic dipole, stores information at the single-molecule level is demonstrated.

This Review provides an overview of the current understanding of the physics of organic–inorganic two-dimensional halide perovskites.

The internal surface of an optical fibre can be covered by uniform two-dimensional-material layers for highly nonlinear and low-loss light propagation.

Function implementation and optimization in nanoscale and quantum-electronic devices become increasingly challenging with the growing complexity of the devices. Training a deep neural network with the physical device response and searching for the functionality in the digital device can ease this challenge.

Epitaxial quantum dot charge spin qubits offer efficient quantum light links, but their coherence is limited by interactions with the nanoscale ensemble of atomic nuclear spins. Employing nuclear spins instead as its hardware, strain-free GaAs/AlGaAs quantum dots can constitute a fully functional two-qubit quantum register.

Holography of incoherent emission from SERS probes allows multiplexed single-particle localization in three dimensions in one shot using a wide-field microscope.

Surface emission from a topological mid-gap cavity shows large free spectral range and arbitrary mode degeneracy.

A Gd@C₈₂ molecule shows electric polarization switching behaviour under a gate bias voltage, thus demonstrating a single-molecule electret device.

A hexagonal boron nitride nanocoating grown directly on a stainless-steel mesh enables ultrahigh power input intensity in an electrothermal membrane distillation system to desalinate hypersaline solutions with exceptionally high water flux, single-pass water recovery and heat utilization efficiency.

Foliar application of different forms of nanoscale copper to plant seedlings induces material-specific biochemical and molecular changes in root tissue that stimulate plant defence against soybean sudden death syndrome.

A fluoropolymer-based cancer nanovaccine that delivers antigens directly to the cytosol of dendritic cells and elicits strong antitumour immune responses inhibiting tumour growth in animal models can be used to produce personalized treatment for post-surgical immunotherapy.

A shape-changing pH-responsive cancer vaccine delivers antigenic peptides directly to the cytoplasm and boosts the cellular immune response upon activation of the inflammasome pathway, efficiently inhibiting tumour growth and extending survival in animal tumour models.
