An optical analogue of magic-angle twisted graphene bilayer gives rise to rigorously stopped light, which coupled with gain allows for a new type of a nanolaser with remarkable figures of merit.

This Perspective relates seemingly diverse examples of chemically driven non-equilibrium systems (dissipative assembly, self-replicators, molecular motors, oscillators) using a common conceptual framework, and discusses how catalytic cycles can be coupled to dynamic processes.

Measuring the gate capacitance serves as a probe of the correlated states in MoSe₂/WS₂ moiré superlattices, which can be further controlled via sample–gate coupling.

Optical spectroscopy can identify chiral indices of individual carbon nanotubes, but has so far been unable to determine their handedness because of the weak chiroptical signal. Rayleigh scattering circular dichroism now enables the identification of both chiral indices and handedness of individual nanotubes.

Continuous-time data representation and frequency multiplexing enable the implementation of a scalable massively parallel computing scheme in a nanoscale crossbar array for applications in intelligent edge devices.

Non-trivial topological magnetic textures, such as skyrmions, merons or vortices, possess topological charges Q with absolute values smaller or equal to one. Now, skyrmion bundles, multi-Q three-dimensional skyrmionic textures, are observed and their current-driven dynamics are studied.

Kinetics-controlled van der Waals epitaxy in the near-equilibrium limit by metal–organic chemical vapour deposition enables precise layer-by-layer stacking of dissimilar transition metal dichalcogenides.

Twisted photonic graphene superlattices enable the realization of high-performance room-temperature magic-angle lasers.

A droplet falling on a non-wetting plane is expected to randomly roll. Tang et al. uncover that by interfacing piezoelectric crystal plane, droplets self-propel in a furcated direction, a motility fuelled by cross-scale thermo-piezoelectric coupling.

A correlated structural and chemical evolution of silicon and the solid–electrolyte interphase was unveiled in three dimensions by integrating sensitive elemental tomography, an advanced algorithm and cryogenic scanning transmission electron microscopy.

Small semiconductor nanocrystals control the assembly of larger plasmonic nanostructures through interfacial self-limiting aggregation, leading to permeable and colloidally stable photoactive hybrids for photocatalysis and tracking of light-induced electron transfer.

Despite its great potential, immune checkpoint blockade has shown efficacy in only a restricted number of patients. In this Article, the authors present a nano-based platform for the co-delivery of chemo- and immunotherapeutics that shows efficient synergic antitumour activity in large, hard-to-treat tumour models.

Synergizing metal–support interactions and spatial confinement through atomic copper grippers boost the dynamics of highly loaded atomic nickel for high activity, high thermal/chemical stability and unprecedented coke inhibition in hydrogenation reactions.

Understanding the fundamental nano–bio interactions of nanomaterials intended for biomedical use might unlock potential alternative applications. Here the authors reveal a tumoricidal mechanism of black phosphorus nanomaterials where these nanomaterials directly affect the mitotic centrosome machinery by suppressing polo-like kinase 1, suggesting that nanomaterials can be applied in targeted cancer therapy with their intrinsic nano–bio properties.
