The Key Steps and Distinct Performance Trends of Pyrrolic vs. Pyridinic M-N-C Catalysts in Electrocatalytic Nitrate Reduction

Through combined theoretical modeling and experimental validation, this study elucidates the distinct performance trends and rate-determining mechanisms of pyrrolic versus pyridinic M-N-C catalysts in electrochemical nitrate reduction, revealing that adsorption and protonation of nitrate govern the reaction while demonstrating the limitations of classical thermodynamic models in accurately predicting catalytic performance.

Tunable electrocaloric effect in lead scandium tantalate through calcium doping

This study demonstrates that calcium doping in highly ordered lead scandium tantalate (PST) enables precise tuning of its phase transitions to induce both conventional and inverse electrocaloric effects, thereby expanding the material's effective cooling range from 263 K to 353 K for use in cascaded electrocaloric devices.

High-Pressure Tuning of Electrical Transport in Freestanding Oxide Films

This paper introduces a novel experimental platform for high-pressure transport measurements in freestanding oxide films, which reveals a complex, dimensionality-dependent pressure-driven phase diagram in SrIrO3 featuring distinct semimetal-insulator and insulator-metal transitions in 3D films compared to the pressure-robust insulating state of 2D monolayers.

Impact of Absorption due to Zero-Field Splitting on Loss in Dielectrics: A Case Study in Sapphire

This paper proposes that transitions between zero-field-split states of paramagnetic impurities (such as Cr, Fe, and V) in sapphire generate magnetic absorption that contributes a loss tangent of 10−910^{-9}–10−810^{-8} at 4.5 GHz, suggesting this mechanism is a significant limiting factor for the coherence times of superconducting qubits.

Revealing domain wall stability during ultrafast demagnetization

Using ultrafast sub-wavelength extreme ultraviolet imaging, researchers demonstrated that magnetic domain walls in ferro- and ferrimagnetic thin films remain remarkably stable in position, shape, and width even during up to 50% ultrafast demagnetization, revealing the localized nature of photoinduced demagnetization and offering new insights for all-optical magnetic control.

Photoengineering the Magnon Spectrum in an Insulating Antiferromagnet

This study demonstrates that resonant above-bandgap optical excitation in the insulating antiferromagnet DyFeO3 induces a near-total collapse of the THz magnon gap by transiently reducing the exchange interaction by nearly 90%, thereby establishing a pathway for ultrafast, light-driven control of antiferromagnetic spin dynamics.

Approximate Excited-State Potential Energy Surfaces for Defects in Solids

This paper introduces and benchmarks an efficient approximation technique that quantifies electron-phonon coupling for solid-state defects using only excited-state forces at the ground-state geometry, demonstrating that key optical properties can be accurately predicted with minimal atomic displacements while establishing the one-dimensional accepting-mode Huang-Rhys factor as a strict upper bound.

Pairing-induced Momentum-space Magnetism and Its Implication In Optical Anomalous Hall Effect In Chiral Superconductors

This paper generalizes Onsager's relation for a single-orbital spinful Hamiltonian to identify two distinct mechanisms of pairing-induced momentum-space magnetism—arising from Cooper pair angular momentum and spin-orbit coupling, respectively—that drive the optical anomalous Hall effect in chiral superconductors, thereby highlighting the essential role of spin degrees of freedom.
