Synthesis and evaluation of water-soluble antioxidants derived from l-carnosine and syringaldehyde (or vanillin).

Polyphenols are well known for their health-related benefits, including antioxidant activities, but most of them are hydrophobic, decreasing their bioavailability. This study reports water-soluble trimeric antioxidants synthesized with l-carnosine and the hydrophobic ortho-methoxy-substituted phenolic unit, syringaldehyde or vanillin. In the DPPH assay, carnosine-syringaldehyde (7.

Effects of Per- and Polyfluoroalkylated Substances on Female Reproduction.

Per- and poly-fluoroalkylated substances (PFAS) are a large group of chemicals that persist both in the environment and in the body. Legacy PFAS, e.g.

Development of Pd-based catalysts for hydrogenation of nitrite and nitrate in water: A review.

Pd-based catalytic hydrogenation for nitrate decontamination has been the subject of extensive research over the past 30 years. Advances in computational simulation, nanomaterial synthesis, and experimental characterization in the past decade have generated new understandings of the reaction mechanisms, guided the development of various catalysts with enhanced performance, and brought revolutionary upgrades to conventional nitrate treatment technologies. However, technical and economic challenges are still limiting its large-scale implementation.
