Ru single atoms and RuP nanoclusters are co‐anchored in N, P, and B co‐doped porous carbon nanospheres via in situ carbonization/phosphidation of a boronate polymer precursor. RuP activates water, while nearby Ru single atoms accelerate H2 formation through H* transfer. The catalyst delivers low overpotential and high durability in alkaline HER and AEM

Spin Defects in Hexagonal Boron Nitride as 2D Strain Sensors
We demonstrate that boron‐vacancy (VB${\rm V}_{\rm B}$) centers in hexagonal boron nitride (hBN) enable quantitative strain sensing with sub‐micrometer resolution. Using this approach under continuously tunable in‐plane stress, we precisely quantify strain‐induced shifts of the E2g${\rm E}_{2{\rm g}}$ Raman mode in multilayer hBN, establishing VB${\rm ...

Clean Up Behind You ‐ Novel Patterning Approach for Solid Immersion Lenses
A focused ion beam (FIB) milling strategy enables rapid fabrication of solid immersion lenses (SILs) with smooth, debris‐free surfaces eliminating the need for post‐processing. The optimized pattern improves efficiency and surface quality. SILs containing NV centers are also investigated, confirming the technique's suitability for quantum and photonic ...

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...
