The authors investigate the origins of chirality transfer across length scales, quantitatively demonstrating how chirality propagates from the molecular to liquid crystal level in filamentous virus systems.
Here, the authors observe that in thin films of antiferroelectric PbZrO3, substrate clamping enhances the electromechanical response, with expansion purely in the out-of-plane direction, achieving 1.7% strain for 100-nm-thick films.
The authors demonstrate a programmable topological photonic chip with large-scale integration of silicon photonic nanocircuits and microresonators that can be rapidly reprogrammed to implement diverse multifunctionalities.
Understanding the origin of photoinduced water splitting on TiO2 is crucial to control photocatalytic surface reactions. A photoexcited-hole-transfer-driven mechanism now shows that water dissociation is strongly coupled with dynamic lattice distortion (photoexcited phonons) on TiO2 surfaces.
Although structurally ordered intermetallic nanocrystals are promising electrocatalysts for fuel cells, their high-temperature large-scale preparation has proved challenging. A low-melting-point-metal-induced bond strength weakening strategy to promote alloy catalyst ordering is now proposed.
Quantum coherent control of single-photon-emitting defect spins have been reported in hexagonal boron nitride, revealing that spin coherence is mainly governed by coupling to a few proximal nuclei and can be prolonged by decoupling protocols.
Integrating electrochemically actuated soft robotics with ultra-flexible microelectrodes enables reversible and gentle wrapping around nerves for high-quality recordings.
The authors report the sweet-spot operation of germanium hole spin qubits, exploring the optimization of the external magnetic field orientation, the g-tensor and its electric tunability, and hyperfine interactions.
The detailed interplay between electronic and lattice dynamics in two-dimensional perovskite materials remains elusive. Here the authors establish the room-temperature polaronic nature of the excitons in two-dimensional Dion–Jacobson-type perovskites.
Lithium-rich oxygen-redox cathodes demonstrate high capacities, but lose energy density when cycled, showing cation disordering and formation of nanovoids and bulk molecular O2. These structural changes are shown to be a consequence of a kinetically viable and thermodynamically favoured local phase segregation mechanism.
An approach combining machine learning and combinatorial chemistry enables the creation and evaluation of ionizable lipid libraries for lipid nanoparticle formulation to effectively deliver messenger RNA to several cells and tissues.
Ultrathin and flat crystals of bismuth are grown between the atomically flat layers of a van der Waals material. These crystals exhibit outstanding electronic properties, including gate-tunable quantum oscillations of the magnetoresistance.
Control over topological antiferromagnetic entities is achieved at room temperature in multiferroic nanodevices using an electric field that induces magnetoelectric coupling to ferroelectric centre states.
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.
A synthesis method for large-scale conjugated polymers as well as studies under operational conditions show that research on organic mixed ionic–electronic conductors continues to progress.
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.
