Green hydrogen production through seawater electrolysis is a promising strategy, although challenges such as sluggish oxygen evolution reaction (OER) kinetics and chlorine (Cl⁻) corrosion hinder its practical applicability. A novel fluorine (F)-doped cobalt (Co) and iron (Fe) layered metal hydroxide (F-CoFe LMH-8) is developed as a robust bifunctional catalyst achieving 81.23 and 265.5 mV at 10 mA cm⁻² for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), respectively. Theoretical and experimental studies demonstrate that the F-doping modulates the electronic structure, effectively tuning Fe sites toward a high-spin configuration that optimizes binding energies and induces a chlorophobic effect that repel corrosive (Cl⁻) ions. Notably, the F-CoFe LMH-8( +|| −) bifunctional catalyst integrated anion exchange membrane water electrolyzer (AEMWE) exhibited outstanding performance for continuous H₂ production, achieves a current density of 1.2 A cm⁻² in 1 M KOH, 1.02 A cm⁻² in 1 M KOH + 0.5 M NaCl, and 1 A cm⁻² in 1 M KOH in seawater at 2.3 V. Furthermore, a long short-term memory-based machine learning model was employed to forecast and predict the stability of F-CoFe LMH-8. This approach provides a comprehensive pathway for heuristic design of durable, chlorophobic, and advanced electrocatalyst for seawater-based AEMWE and large-scale hydrogen production.

A newly developed laser Speckle-based Curvature Optical Metrology (SCOM) system is enabling high-precision, two-dimensional curvature mapping of strongly curved and freeform X-ray mirrors—expanding the boundaries of optical fabrication and beamline performance.

Chronic neuropathic pain often brings a cruel companion: debilitating anxiety. These two conditions fuel each other, making treatment notoriously difficult.

Scientists in China have proposed a generalized Doppler effect framework by constructing vector-polarized dual-vortex light fields via spin–orbit coupling. A single reflection generates four independent frequency-shift signals, with mixed signals offering an order-of-magnitude improvement in measurement accuracy and unambiguous motion direction discrimination. This technique unifies linear, rotational, and vector Doppler methods for precision velocimetry and medical imaging.

A novel interfacial engineering strategy for 3D-printed metal-cermet composites is provided, effectively suppressing sintering-induced cracking, and opens a promising pathway for manufacturing robust components for extreme environments.

A landmark review published in Targetome establishes targetome as a unifying concept for systematic, synergistic multi‑target intervention, breaks through the limitations of the “one gene, one target, one drug” paradigm, and proposes a three‑stage innovation roadmap to accelerate rational discovery of next‑generation combination drugs for chronic diseases including cancer, cardiovascular, metabolic, and neurodegenerative disorders.
