Long-range lateral Josephson supercurrents are observed in a chiral non-collinear antiferromagnet, indicating topologically generated triplet pairing states.
A kirigami-inspired stent-based system has been developed for extended local drug delivery to the gastrointestinal and respiratory tracts as well as the vascular system.
An unconventional chiral charge order is observed in a kagome superconductor by scanning tunnelling microscopy. This charge order has unusual magnetic tunability and intertwines with electronic topology.
Solid electrolytes are promising for enabling the use of Li metal anodes but Li infiltration along grain boundaries can lead to battery failure. Li infiltration in a model solid oxide electrolyte is now found to be strongly associated with local electronic band structure.
An intermediate cube phase with a medium-range order structure is identified in Pd-Ni-P metallic glass, which links the amorphous and crystalline phases.
Nanomaterials may present interesting catalytic properties, but well-defined model systems are rare. Here, a Au–Pd core–shell catalyst is investigated for selective hydrogenation of butadiene, with shell-thickness-dependent catalytic activity, high selectivity and activity 50 times greater than that of alloyed counterparts.
Optical anisotropy and electronic compressibility measurements are used to uncover stripe phases, where the rotational symmetry of charge density is spontaneously broken, in a two-dimensional semiconductor moiré superlattice.
Non-thermal lattice control of exchange interactions allows for picosecond coherent switching between competing antiferromagnetic and weakly ferromagnetic order.
Scanning tunnelling spectroscopy and ab initio simulations reveal buckling reconstruction and in-plane strain redistribution in WSe2/WS2 moiré heterostructures.
A percolation theory of alloy passivation is developed accounting for selective dissolution and the quantity of metal dissolved during the primary passivation process, which provides a quantitative way for designing corrosion-resistant alloy compositions.
Transverse thermeoelectrics can simplify devices as the electric field and heat gradient are perpendicular, but the power output is much less than in standard devices. Here, by forming a closed circuit of thermoelectric and magnetic materials, a much larger transverse thermopower is generated.
A wide range of highly crystalline, two-dimensional layered metal oxides can be formed by controlled oxidation of the metals at the metal–gas interface.
Reversible strains are widely used in high-technology systems, with piezoelectrics showing fast response but low strain. Here, ferroelectric C6H5N(CH3)3CdCl3 is shown to produce a strain of 21.5%, two orders of magnitude larger than other piezoelectrics, due to organic molecules preventing 180° polarization switching.
Diffuse X-ray scattering with femtosecond resolution shows the formation and relaxation of polaronic distortions in halide perovskites. These structural changes are also quantified and correlated to transient changes in carrier effective mass.
A carbazole isomer, typically present as an impurity in commercially produced carbazole batches, is shown to be responsible for the ultralong phosphorescence observed in these compounds and their derivatives.
