Despite its tiny magnetization, the non-collinear antiferromagnet YbMnBi2 is shown to possess exceptional transverse thermoelectric performance owing to its anisotropic transport properties.
Previous demonstrations of long-range supercurrents through magnetic materials were achieved only at liquid helium temperatures. Now, using specially tailored samples, long-distance supercurrents have been realized at temperatures as high as 40 K.
Epitaxial growth followed by topotactic reduction yields superconducting nickelate phases with the same hole-doping level as that obtained by chemical substitution, without causing structural disorder.
Glass-forming ability in metallic systems is related to the diversity of atomic packing schemes quenched into the glassy state, which manifests itself in the width of the first broad X-ray diffraction peak. This provides a swift way for screening libraries of deposited alloy films and searching for good glass formers.
Proposed new regulations for the European battery industry could end up making the electrification of transport harder — and reveal the complexity of creating sustainable markets.
The liquid nature of hard glasses is demonstrated by broadband stress relaxation experiments. The rheology and dynamic transition of various glass systems can be unified by a universal scaling law in the time–stress–temperature–volume domain.
Parallel-plate capacitors of the two-dimensional materials hBN and NbSe2 are integrated with aluminium Josephson junctions to realize transmon qubits with coherence times reaching 25 μs.
The real-space magnetic configurations of a zero-dimensional skyrmionic vortex structure is uncovered using electron holography and micromagnetic simulations.
Metal oxide–zeolite bifunctional catalysts allow coupling of reactions and so enhance catalytic processes, but structure and reactivity control is difficult. Here, a general synthesis is presented for metal oxide–zeolite double-shelled hollow spheres, which outperform other catalysts for petroleum production.
High-quality wafer-scale single-crystal monolayer graphene is achieved on sapphire substrate, by epitaxially growing graphene at the Cu(111)/sapphire interface and then detaching Cu film via immersion in liquid nitrogen and rapid heating.
Stable solid–electrolyte interphases on Li anodes are crucial for reliable Li metal batteries. A suspension electrolyte design that modifies the Li+ solvation environment in liquid electrolytes and creates inorganic-rich interphases on Li is now reported.
Although using proton (H+) conductors is attractive for energy applications, practical conductivity at intermediate temperatures (200–400 °C) remains a challenge. A K2NiF4-type Ba–Li oxyhydride is shown to exhibit a temperature-independent hydrogen conductivity of more than 0.01 S cm–1 above 315 °C.
Grain boundary conductivity limitations are ubiquitous in material science. Illumination with above-bandgap light is now shown to decrease grain boundary resistance in a model gadolinium-doped ceria solid ionic conductor.
Symmetry breaking in colloidal crystals is achieved with DNA-grafted programmable atom equivalents and complementary electron equivalents, whose interactions are tuned to create anisotropic crystalline precursors with well-defined coordination geometries that assemble into distinct low-symmetry crystals.
The separation of multicomponent mixtures is performed by distillation, as multiple-membrane cascades are too complex. Here, a porous organic cage composite undergoes solid-state transformation in solvent; this alters pore size, enabling graded separation of three dyes with a single membrane.
