Self‐powered H2O2 production using a Zn–air electrochemical cell employing a polymer blend membrane

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Hydrogen peroxide (H2O2) is a strong oxidant and a carbon‐free fuel which is synthesized by the costly anthraquinone method, prompting research into highly efficient electrocatalytic processes. RESULTS This study introduces a self‐sustaining Zn–air electrochemical cell with a carbon black cathode and an efficient polymer‐blend ion ...

Liquid Chromatography Coupled With High‐Resolution Mass Spectrometry Profiling of Metabolites in Cassia alata Flower Extracts and Their DPPH Free Radical Scavenging Activity [PDF]

Anal Sci Adv
ABSTRACT Cassia alata flowers remain phytochemically under‐characterized relative to the leaves. However, floral tissues can harbour distinct and, in some species, more abundant phenolic and flavonoid profiles, representing an unexploited source of antioxidant phytochemicals with potential functional‐food and nutraceutical relevance. Also, Cassia alata

Sensory and chemical profiles of bread derived from the novel semi‐ and wholegrain flour enrichment of Triticum aestivum L. old genotypes with organic stinging nettle

JSFA reports, Volume 5, Issue 3, Page 104-112, March 2025.
Abstract Background Bread made from refined Triticum aestivum L. flour, a staple food in large parts of the world, is considered a nutrient security risk. Strategies used to enhance the nutritional and functional properties of wheat‐derived food products include the use of semi‐ or wholegrain flour, old genotypes, and enrichment through fortification ...
