Soft pressure sensors drift under prolonged high stress because of the creep of soft materials, which causes inaccurate measurements. Now, through molecular-level design, a leakage-free and creep-free polyelectrolyte elastomer is synthesized, and an iontronic sensor using the polyelectrolyte elastomer shows very low signal drift under a high static pressure.
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.
Non-layered transition metal carbides (TMCs) and layered transition metal dichalcogenides (TMDs) can form various heterostructure configurations through chemical conversion. This Review highlights the progress in the fabrication and control of TMC/TMD heterostructures and the exotic properties arising from these interfaces.
Molecular materials for computing progress intensively but the performance and reliability still lag behind. Here the authors assess the current state of computing with molecular-based materials and describe two issues as the basis of a new computing technology: continued exploration of molecular electronic properties and process development for on-chip integration.
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.
Electrocaloric effects have not hitherto been experimentally studied at a phase transition created by strain. It is now shown that the continuous transition created by epitaxial strain in strontium titanate films greatly enhances electrocaloric effects over a wide range of temperatures, including room temperature.
Single-crystal black phosphorus nanoribbons have been grown through chemical vapour transport, using black phosphorus nanoparticles as seeds. The nanoribbons orient exclusively along the zigzag direction and have good semiconductor properties that render them suitable for use as channel material in field-effect transistors.
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.
Two-dimensional (2D) materials, despite their small thickness, can display chirality that enables prominent asymmetric optical, electrical transport, and magnetic properties. This Perspective discusses the intriguing physics enabled by the structural chirality and the possible ways to create and control chirality in 2D materials.
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.
