Bi-doped ruthenium oxide nanocrystal for water oxidation in acidic media.

There is an urgent need to develop a cost-effective and highly efficient acidic OER catalyst to support the progress of proton exchange membrane water electrolysis technology. Ruthenium-based catalysts, which possess high activity and significantly lower cost compared to iridium-based catalysts, emerge as competitive candidates. However, their suboptimal stability constrains the wide application of RuO.

Single atomic Ru in TiO boost efficient electrocatalytic water oxidation to hydrogen peroxide.

Electrocatalytic two-electron water oxidation affords a promising approach for distributed production of HO using electricity. However, it suffers from the trade-off between the selectivity and high production rate of HO due to the lack of suitable electrocatalysts. In this study, single atoms of Ru were controllably introduced into titanium dioxide to produce HO through an electrocatalytic two-electron water oxidation reaction.

Melatonin Attenuates Vascular Smooth Muscle Contraction Through the γ-Secretase/Notch Intracellular Domain/Myocardin Pathway.

Inositol 1, 4, 5-trisphosphate (IP3) signaling-mediated calcium release drives the contraction of vascular smooth muscles and hence regulates blood vessel volume and blood pressure. Melatonin supplementation has been suggested to be beneficial for hypertension. To determine whether the blood pressure-lowering effect of melatonin was accounted for by IP3 signaling, we evaluated the vasoconstriction response and IP3 signaling in isolated mouse thoracic aortic rings during melatonin incubation.

Construction of a crystalline 14-metal Zn-Nd rectangular nanocluster with a dual-emissive response towards metal ions.

A crystalline 14-metal Zn-Nd cluster [ZnNdL(OAc)(O)(NO)(OCH)] (1) was constructed using a flexible Schiff base ligand with long-chain (CH)O(CH)O(CH) backbone. 1 exhibits a nanoscale rectangular structure (10 × 14 × 18 Å). Besides the visible ligand-centered emission, 1 displays typical NIR luminescence of Nd.

Anion Dependent Self-Assembly of Polynuclear Cd-Ln Schiff Base Nanoclusters: NIR Luminescent Sensing of Nitro Explosives.

Two types of polynuclear Cd-Ln complexes [CdLnL(NO)Cl(DMF)] [Ln = La () and Nd ()] and [LnCdL(NO)(DMF)](OH) [Ln = La () and Nd ()] were constructed using a new Schiff base ligand which has a long backbone with two phenyl groups. The Schiff base ligands show a "twist" configuration in -. The crystal structures show that the molecular dimensions of and are about 6 × 10 × 15 Å.
