Engineering the Local Electronic Configuration of Diatomic Iron-Nickel Site for Enhanced Nitrate and Ammonia Co-Electrolysis Activity.

Anthropogenic activities have caused a significant rise in nitrate and ammonia nitrogen levels in natural water bodies, disrupting the balance of the nitrogen cycle. The electrocatalytic reduction of nitrate and the oxidation of ammonia are promising strategies for converting polyvalent nitrogen into nontoxic and harmless N. Herein, a bifunctional electrode loaded with diatomic iron-nickel site on porous N-doped carbon (FeNi-NC) is designed and successfully applied for the co-electrolysis of nitrate and ammonia.

Accelerated Dynamic Reconstruction in Metal-Organic Frameworks with Ligand Defects for Selective Electrooxidation of Amines to Azos Coupling with Hydrogen Production.

Electrosynthesis coupled hydrogen production (ESHP) mostly involves catalyst reconstruction in aqueous phase, but accurately identifying and controlling the process is still a challenge. Herein, we modulated the electronic structure and exposed unsaturated sites of metal-organic frameworks (MOFs) via ligand defect to promote the reconstruction of catalyst for azo electrosynthesis (ESA) coupled with hydrogen production overall reaction. The monolayer Ni-MOFs achieved 89.

Advances in Biomimetic Photoelectrocatalytic Reduction of Carbon Dioxide.

Emerging photoelectrocatalysis (PEC) systems synergize the advantages of electrocatalysis (EC) and photocatalysis (PC) and are considered a green and efficient approach to CO conversion. However, improving the selectivity and conversion rate remains a major challenge. Strategies mimicking natural photosynthesis provide a prospective way to convert CO with high efficiency.

CagA orchestrates eEF1A1 and PKCδ to induce interleukin-6 expression in -infected gastric epithelial cells.

Background: colonises the stomach of approximately 50% of the global population. Cytotoxin-associated gene A protein (CagA) is one of the important virulent factors responsible for the increased inflammation and increases the risk of developing peptic ulcers and gastric carcinoma. The cytokine interleukin-6 (IL-6) has particularly important roles in the malignant transformation of gastric and intestinal epithelial cells as it is upregulated in -infected gastric mucosa.

A Novel Europium Chelate Coated Nanosphere for Time-Resolved Fluorescence Immunoassay.

A novel europium ligand 2,2',2'',2'''-(4,7-diphenyl-1,10-phenanthroline-2,9-diyl) bis (methylene) bis (azanetriyl) tetra acetic acid (BC-EDTA) was synthesized and characterized. It shows an emission spectrum peak at 610 nm when it is excited at 360 nm, with a large Stock shift (250 nm). It is covalently coated on the surface of a bare silica nanosphere containi free amino groups, using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride and N-Hydroxysuccinimide.
