Metabolism of hydrogen sulfide (H2S) and Production of Reactive Sulfur Species (RSS) by superoxide dismutase

Redox Biology, 2018
Reactive sulfur species (RSS) such as H2S, HS•, H2Sn, (n = 2–7) and HS2•- are chemically similar to H2O and the reactive oxygen species (ROS) HO•, H2O2, O2•- and act on common biological effectors.

Self‐Nitriding Nanostructured Transition Metal Nitrides in Architected‐Carbon Matrices: Unveiling Mechanisms and Advancing Performance in Lithium‐Sulfur Pouch Cells

Advanced Science, EarlyView.
Imidazolium PIL nanoparticles, as an N‐rich template and morphology director, enable a colloidal self‐nitriding route to TMNs (VN, Mo2N) within controlled solid/hollow carbon architectures. As sulfur hosts/additives, TMNs accelerate Li–S redox kinetics and support high‐loading cathodes.

Precise Tailoring 3D Printed In Situ Toughening Low‐k Microwave Transparent Structure via Thiol‐acrylate Chain Transfer Behavior

Advanced Science, EarlyView.
An in situ thiol–acrylate chain transfer‐mediated toughening strategy is introduced for Digital Light Processing (DLP) printing. Benefiting from its excellent printability, a printed gyroid lattice‐filled plate (100 µm wall thickness) achieves 92% transmittance at 10 GHz under a 50° incidence angle following structural optimization. ABSTRACT The unique

Rigid‐Flexible Coupling Units Enable Robust Large Birefringence

Advanced Science, EarlyView.
A rigid–flexible coupling strategy, combining flexible (S3)2− linear units with rigid (VO4)3− tetrahedra, yields Sr4(VO4)2S3—a robust crystal exhibiting large birefringence (Δn = 0.52@550 nm) and remarkable thermal, air, and water stability. ABSTRACT Birefringent crystals are central to polarization control in laser technologies (e.g., wave plates and ...
