Neutron scattering, electron spin resonance, muon spectroscopy and magnetization measurements are applied to evidence a quantum spin liquid phase in NdTa7O19.
In anisotropically shaped photocatalyst particles different constituent facets may form inter-facet junctions at their adjoining edges. Using multimodal functional imaging, inter-facet junction effects on anisotropically shaped bismuth vanadate particles are revealed.
Zinc oxide-based two-dimensional electron systems are demonstrated to be high-mobility systems that enable the study of low-temperature phases of strongly interacting electrons.
A moiré-trapped charge density wave is observed at room temperature in a twisted transition metal dichalcogenide system and attributed to local strain variation due to atomic reconstruction.
Josephson coupling over micrometres and at tens of kelvins is demonstrated across the half-metallic manganite La0.7Sr0.3MnO3 combined with the superconducting cuprate YBa2Cu3O7.
Lignocellulosic waste is transformed into fungal–bacterial biocomposites that can be processed into recyclable, human-scale structural objects with biosynthetic and sensing–reporting functionalities.
Organic blends based on cationic photoredox catalyst dopants in neutral donor hosts show p-type charge transport behaviour. This favours reduced reactivity to oxygen in organic long-persistent luminescence materials responsive to visible light.
This allows versatile non-volatile tuning of the mutual synchronization of chains of up to four oscillators and provides a path toward individual oscillator control in large oscillatory arrays.
Non-classical crystallization may proceed through formation of intermediate phases, but it is not known whether these are linked to the final crystallization. Here, using an atomic force microscope at 90 bar, brucite carbonation is directly observed, with an amorphous intermediate acting as the seed for crystalline nesquehonite.
A full kinetic pathway of a non-classical nucleation-induced phase transformation through metastable states is elucidated at sub-ångström resolution in a technologically important titanium alloy.
Designing electrode architectures for Li-ion batteries that can be reversibly accessible for ion storage can be challenging. Using operando techniques the mechanistic origin of lithiation-induced phase transformations in a V2O5 model cathode is now clarified.
Glass-like supramolecular polymer networks with high compressibility and fast self-recovery are fabricated using host–guest crosslinkers with slow dissociation kinetics.
The anomalous Nernst effect (ANE) in topological materials with large Berry curvature shows great potential for transverse thermoelectrics, but antiferromagnets typically show small ANEs. The antiferromagnet YbMnBi2 has an ANE thermopower of 3 μV K−1, similar to ferromagnets, and a larger ANE conductivity.
Colour centres are a promising quantum information platform, but coherence degradation after integration in nanostructures has hindered scalability. Here, the authors show that waveguide-integrated VSi centres in SiC maintain spin-optical coherences, enabling nuclear high-fidelity spin qubit operations.
The tunability of covalently bound cationic and anionic moieties of zwitterionic materials makes them attractive for potential applications. A family of zwitterions exhibiting molecular disorder and plasticity allows their use as a solid-state conductive matrix.
Controlled synthesis of heterostructured III-V–II-VI nanocrystals shows that dipole moments formed at the core–shell interface can tune the optoelectronic properties of these nanomaterials and their performance in light-emitting devices.
The influence of stress relaxation of the extracellular matrix on the formation of intestinal organoids was investigated. It was shown that a stress-relaxing synthetic matrix promotes crypt budding through increased symmetry breaking and niche cell formation.
The authors use scalar magnetic X-ray tomography under applied magnetic fields to directly visualize the three-dimensional shape of individual skyrmion strings.
Triplet exciton harvesting through thermally activated delayed fluorescence is shown to be effective also under X-ray excitation, increasing the efficiency and imaging quality of X-ray detectors based on organic scintillation.
