A laser‐driven strategy enables precise microstructural modulation of Mo₂C, achieving nanoscale grain control (15.6 ± 5 nm) and an ultrahigh grain boundary density (130 µm−1). Moreover, high‐angle grain boundaries enhance active sites, facilitate electron transport, and optimize hydrogen adsorption kinetics, significantly reducing overpotential.

Near‐Field Phonon Nanoscopy and Imaging of Structural Variants in Mixed Phase BiFeO3
Nano‐Fourier transform infrared spectroscopy and scattering scanning near‐field optical microscopy imaging reveal the phonon response of nanoscale phase variants in mixed‐phase BiFeO3 (BFO). Direct mid‐infrared imaging of associated distinct vibrational signatures is used as a non‐invasive optical detection method for electrical switching of ...

Control of Ferromagnetism of Vanadium Oxide Thin Films by Oxidation States
The nonstoichiometric VOx exhibits a distinct ferromagnetic hysteresis loop and demonstrates a high magnetic susceptibility (χ=dMdH$ = \frac{{dM}}{{dH}}\;$∼10). Micromagnetic simulations show the results of the “partial volume fraction ferromagnetic phase model” for VOx/Co/Pt structure.

Scaling‐Up of Structural Superlubricity: Challenges and Opportunities
At increasing length‐scales, structural superlubricity (SSL) faces challenges from physical and chemical energy dissipation pathways. This study reviews recent experimental and theoretical progress on these challenges facing the scaling‐up of SSL, as well as perspectives on future directions for realizing and manipulating macroscale superlubricity ...

Near‐Infrared Circularly Polarized Electroluminescence with Switchable Handedness in Organic LEDs
The first fully‐organic circularly polarized near‐infrared OLED, using a co‐assembled active layer of ITIC and a chiral inducer, exhibits dissymmetry values up to 0.074 and 1.65 Wsr−1m−2 radiance. The circular polarization sign can be switched by manipulating the position of the recombination zone, resulting in enhanced device performance and stability.
