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.
Cancer cells adjust the composition of their glycocalyx to increase its thickness and create a physical barrier that shields them from immune recognition and engagement.
Considering responsive materials as transient collective assemblies rather than individual shape-changing objects allows for emergent functionalities that cannot be derived from the properties of single objects but are driven by interactions between them.
Early detection of electrical degradation can be identified by colour change due to the chromogenic response of blended molecules in dielectric polymers.
The antiferromagnetic material haematite, named for its blood-red colour, hosts swirling spin vortices termed merons. The rotation sense of such antiferromagnetic vortices has now been imaged in real space.
