Crystal Chemistry of a Nickelate Superconductor: La/Pr Distribution, Oxygen Stoichiometry, and High-Pressure Structural Evolution in La2PrNi2O7

Abstract We report a comprehensive structural characterization of La2PrNi2O7, a bilayer Ruddlesden–Popper nickelate that has been described to exhibit high-temperature superconductivity under hydrostatic pressure. Synchrotron X-ray diffraction (SXRD) data and high-resolution neut...

Enzyme-Mimetic Tri-Site Catalyst Enables High-Performance Electrochemical Urea Synthesis

Abstract Electrochemical urea synthesis from CO2 and NO3– offers a low-energy, green alternative to the traditional Bosch–Meiser route. However, mismatched adsorption of C/N intermediates, complex proton-coupled electron transfer, and high C–N coupling barrier on conventional sin...

2D theoretically twistable material database

The study of twisted two-dimensional (2D) materials, in which twisting layers create moiré superlattices, has created opportunities for investigating topological phases and strongly correlated physics. The broader potential of a seemingly infinite set of twistable 2D materials re...

ZrCo 3 B 2 and HfCo 3 B 2 Electrodes Go on Stage for Oxygen Evolution Reaction

ABSTRACT The water electrolysis is one of the key processes for producing hydrogen—a clean and sustainable energy carrier. However, its wide application onto the industrial scale still lack of the long‐lasting and highly efficient electrocatalysts for the kinetically sluggish oxy...

Superconducting Weak Links at Substrate Steps in Bilayer Nickelate Films

Abstract Ambient-pressure superconductivity above 40 K has been realized in bilayer nickelate thin films on SrLaAlO4 (001), yet resistive measurements often exhibit incomplete zero-resistance states and/or two-step superconducting transitions of unresolved origin. We show that th...

Data for "A Fourier-Space Approach to Physics-Informed Magnetization Reconstruction from Nitrogen-Vacancy Measurements"

Measured NV field maps, synthetic ground truth and all 159 reconstructions shown in the main text and the Supplemental Material of the paper (Phys. Rev. Lett., DOI 10.1103/nc5g-3yw9). Each reconstruction directory holds config.json, result.json, m_star.npy, h_proj.npy, h_dem.npy...

Steering Cu Interatomic Distances and Local Steric Environment of Nonporous Coordination Polymers Boosts CO 2 Electroreduction to C 2 Products

ABSTRACT Metal–organic frameworks (MOFs) and porous coordination polymers (CPs) are promising electrocatalysts for CO 2 reduction, but suffer from poor stability and mass transfer limitations at high current densities. While nonporous CPs show efficient CO 2 ‐to‐C 1 conversion wi...

Electronic Conductivity as a Rate‑Limiting Factor for Calcium‑Ion Storage in Layered Vanadium Oxides

ABSTRACT Rechargeable calcium batteries are promising for sustainable energy storage but lack cathode materials that reversibly intercalate Ca 2+ at practical rates. While considerable efforts have focused on improving ionic conductivity, this work investigates how electronic con...

Spontaneous emergence of skyrmions beyond room temperature in boron-doped CrTe

Abstract Magnetic skyrmions are vortex-like spin textures that exhibit remarkable emergent phenomena and hold great promise for applications in spintronics, magnonic devices, and neuromorphic computing. Typically, these spin textures are formed in magnetic samples through the app...
