A double‐sided mechanical interlocking strategy is developed to create robust electrical contact between polymer electrode and metal interconnect. The fibrous structure enables formation of thread–hole adhesion, which only breaks under bulk failure and achieves a record high interfacial energy exceeding 730 J·m−2. This adhesion secures the integrity of

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum
Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

A general, versatile laser‐shock synthesis process is reported to produce various bimetallic CuNi, CuFe, CuCo, and medium‐entropy CuFeCoNi heterostructures, in which crystalline metal nanoparticles are anchored to amorphous hydroxide supports. During nitrate reduction reaction, the heterostructures undergo dynamic amorphous/crystalline reconstruction ...

Layer orientation dictates charge transport in 2D conjugated metal–organic frameworks, yet controllable methods remain scarce. We report surfactant monolayer‐assisted on‐water synthesis of cm2‐scale Ni‐HHTP films with programmable face‐on and edge‐on orientations.

In this work, a synergistic strategy introduces interfacial acid sites, oxygen vacancies, and built‐in electric field into ZnSe/ZnO heterojunction to optimize its electronic structure and electrode micro‐environment. This overcomes sluggish oxygen reduction reaction kinetics and low H2O2 selectivity, achieving record H2O2 productivity (754.4 M gcat−1 ...
