Summary: The oxidation and reduction mechanisms of substituted 4,7-di(pyrrolidin-1-yl)-1,10-phenanthrolines were investigated in non-aqueous environment. The presence of pyrrolidine-1-yl moiety significantly facilitates the reduction of the 1,10phenanthroline structure, while oxidation leads to the formation of hydroxylated compounds. This study paves the way for novel chelating agents and electrochemical technologies for environmental protection.

Summary: The study found a relationship between total flavonoids intake, flavonoid subclasses, and metabolic syndrome. Q2 and Q3 intake of total flavonoids were associated with a 20% and 19% lower risk of incident metabolic syndrome. Flavanones and anthocyanidins intake in Q2 and Q3 also significantly reduced the risk compared to Q1. The most effective doses of total flavonoids, flavanones, and anthocyanidins for preventing metabolic syndrome were 237.67, 34.37, and 23.13 mg/day, respectively.

Summary: The study proposes that water oxidation on hematite can proceed via mixed reaction paths, contrary to the traditional assumption of a single reaction path. By isolating absorption signals of surface states responsible for water oxidation, the research highlights the significant contribution of direct hole transfer, especially for highly doped hematite. This finding challenges existing experimental techniques that rely on oversimplified models and theories.

Summary: This study evaluated the effects of various flavonoids and their condensation product with toxic carbonyl compounds on the oxidative burst process of neutrophils. The results showed that these compounds inhibited the production of reactive oxygen species (ROS), with flavonoids reducing both intracellular and extracellular ROS production, while the condensation product only inhibited extracellular ROS production. These findings contribute to a better understanding of the effects of polyphenols on human health and may have implications for the development of new therapeutic agents against oxidative stress-related diseases.

Summary: Single-atom catalysts (SACs) on hematite photo-anodes act as true catalysts by trapping holes from hematite and providing active sites for water oxidation. Spectroscopic experiments and computer simulations demonstrate reduced hole number and shortened hole lifetime in the presence of SACs. Density functional theory calculations reveal that SACs display a lower onset potential and introduce a mid-gap of 4d state for fast hole transfer and depletion. These findings provide new insights into solar water oxidation and the role of SACs in enhancing semiconductor catalytic performance in photo-assisted reactions.

Summary: Hydrous iridium oxides (IrOx) have been proven to be the best oxygen evolution electrocatalysts for operation in acidic environments. This study utilizes time-resolved operando spectroelectrochemistry to investigate the redox-state kinetics of IrOx electrocatalyst films for both water and hydrogen peroxide oxidation, identifying different redox species and quantifying their concentrations as a function of applied potential. The generation of Ir4.y+ states is found to be the potential-determining step for catalytic water oxidation, while H2O2 oxidation is observed to be driven by the generation of Ir4+ states.
