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.
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.
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.
Polaritonic losses, a root impediment to the many bounties of nanophotonics, may be evaded by resorting to the mathematics of synthetic frequencies offering ‘virtual’ gain.
Highly efficient matrix-free hyperfluorescent organic light-emitting diodes are constructed with remarkably supressed Dexter transfer utilizing narrowband blue emitters encapsulated with hopped alkyl chains.
Pentagonal polyhedral oligomeric silsesquioxane (POSS)-based giant atoms self-assemble into Frank–Kasper phases that have not been previously observed in soft-matter systems.
Better control over the quality of materials dissipates doubts about charge order in infinite-layer nickelates and indicates that a previously observed superstructure is probably a spurious effect related to other crystalline phases. This finding strengthens the similarities between nickelates and cuprates.
Noble gas atoms sandwiched in bilayer graphene are directly visualized with scanning transmission electron microscopy, revealing solid and liquid-like dynamics of two-dimensional cluster structures at room temperature under encapsulation.
Restricting the directional segregation of mobile ions via strategic local ion confinement allows remarkable thermoelectric performance with better stability.
The atomic reconstruction and stacking arrangement in twisted trilayer graphene with a range of varying twist angles are elucidated by four-dimensional scanning transmission electron microscopy, revealing the hierarchical moiré of moiré superstructures that govern the structural symmetry at different length scales.
