We report the highly efficient and chemoselective oxidation of benzylic alcohols catalyzed by sodium copper chlorophyllin in water, producing corresponding arylcarbonyl compounds. Importantly, the catalytic system exhibits a wide substrate scope and high functional group tolerance. Moreover, secondary alcohols and even diarylmethanes were smoothly oxidized to the desired aryl ketones with excellent yields.

This study investigates the nutritional and anti-nutrient profiles of extrudates produced from seven formulations of pearl millet and Bambara groundnut flour in seven different ratios: 20:80, 30:70, 40:60, 50:50, 60:40, 70:30, and 80:20, with 100% pearl millet and 100% Bambara groundnut extrudates used as controls. The extrudates were processed using a twin screw extruder and analyzed for their nutritional and anti-nutritional properties. The findings revealed a rising pattern in the content of fiber, moisture, protein, ash and fat as the substitution of Bambara groundnut increased in the extrudate.

Article Synopsis
- Solid-state polymer electrolytes (SPEs) are gaining attention for sodium metal batteries (SMBs) due to their flexibility and lower interfacial resistance, but they struggle with sodium ion conductivity and unstable interfaces.
- A novel composite electrolyte called PPNM is created by integrating a 3D copper metal organic framework (Cu-MOF) with polyacrylonitrile (PAN) fibers and polyethylene oxide (PEO), enhancing ionic conductivity and sodium ion movement.
- The improved stability and performance of the PPNM electrolyte lead to strong cycling results for Na3V2(PO4)3@C/PPNM/Na full cells, making it a promising strategy for advancing solid-state SMB technology.

Aims: This study aimed to assess the effectiveness of a novel antimicrobial gel, containing copper and silver nanoparticles, for use in root canal disinfection.
Methods: Copper and silver-based gels were created in-house, using a support network of biocompatible polymers, including polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP), and polyethylene glycol (PEG). Six experimental groups were created, three containing silver ions and three copper ions, where the PVA, PVP and PEG ratios were also adjusted in each group to test the gel's physical state.
