An outlook on the potential of lead-halide perovskites as a playground for exciton-polariton studies and for the development of polaritonic devices operating at room temperature is provided.
A non-affine to affine transition in elasticity occurs with the change of system topology in a packing-derived network, which enables the tuning of elastic moduli and Poisson’s ratio.
The area confined between grains in polycrystalline materials can undergo phase transformations under external stimuli, providing prospects for materials design based on grain boundary phase engineering.
Four-dimensional scanning transmission electron microscopy is demonstrated to be a powerful technique for interrogating local strain of twisted graphene bilayers, revealing a two-regime lattice reconstruction process below the ‘magic’ angle.
The combination of multicomponent magnetic nanoparticles and a mechanosensitive ion channel has been shown to achieve fast magnetomechanical stimulation of neurons within the brain.
A computational platform describing the spatial and temporal interactions of monomers during the formation of network polymers provides structure–property relationships that are used to synthesize 3D network polymers with tailored functionalities.
Direct experimental observations reveal that grain boundaries in aluminium oxide migrate by a chain of structural phase transformations within the boundary core.
Nanoarchitected materials have predominantly been studied in the quasi-static regime. Here, the supersonic microparticle impact regime for three-dimensional nanomaterials is uncovered, showcasing extreme energy dissipation and a predictive framework for damage.
Metal nanolattices are fabricated at an unprecedented scale by using a crack-free self-assembly method. The dense nanostructures enable tensile strengths that approach the theoretical limit.
A kirigami-inspired stent-based system has been developed for extended local drug delivery to the gastrointestinal and respiratory tracts as well as the vascular system.

An unconventional chiral charge order is observed in a kagome superconductor by scanning tunnelling microscopy. This charge order has unusual magnetic tunability and intertwines with electronic topology.
Replacing platinum with metal–nitrogen–carbon catalysts for the oxygen reduction reaction in proton exchange membrane fuel cells has been impeded by low activity. These limitations have now been overcome by the trans-metalation of Zn–N4 sites into Fe–N4 sites.
Silica beads encapsulating DNA information and functionalized with DNA labels create an alternative DNA data storage system, where direct random access and data retrieval are enabled by complementary fluorescent strands that identify beads for separation in fluorescence-activated sorting.
Metal-halide and oxide perovskites are a rich playground for fundamental studies and applications. This Review focuses on the opportunities opened by reducing the dimensionality of these materials to two-dimensional monolayers.
Changes in dielectric constant due to intimate mixing of thiophene molecules with different gaps between ionization energy and electron affinity induce gap variations at the single-particle level, finely tunable by controlling the mixture ratio.
