The development of Pd-based bimetallic nanoalloys (NAs) with abundant active sites for achieving highly efficient electrocatalysis in alcohol oxidation deserves continuous attention. Herein, we utilized a facile visible-light-assisted liquid-phase method involving adjusting reaction time to generate active sites, successfully synthesizing one-dimensional (1D) PdAg NAs rich in defects. The optimized 1D PdAg NA exhibits remarkable electrochemical activity, stability, and antipoisonous properties in glycerol oxidation reaction (GOR) and ethanol oxidation reaction (EOR), far exceeding pure Pd and commercial Pd/C catalysts. Notably, compared to glycerol oxidation (1496 mA mg and 4.13 mA cm), the optimized PdAg NA demonstrated higher mass activity (2990 mA mg ) and specific activity (7.86 mA cm) in ethanol oxidation. In summary, this work may provide a strategy for designing low-cost electrocatalysts enriched with defects, thereby promoting the development of high-performance alcohol oxidation reactions.

Although performance enhancements due to trace Fe incorporation into Ni catalysts for the oxygen evolution reaction (OER) have been well documented, the effects of trace versus bulk Fe incorporation into Ni catalysts for the ethanol oxidation reaction (EOR)─a promising anodic alternative to OER─are unclear. Herein, we perform extensive cyclic voltammetry experiments on Ni-based thin films to show that trace Fe incorporation from electrolyte impurities has a minimal impact on EOR performance, while codeposited Fe significantly suppresses catalytic current (by half at 1.5 V).

Background: Alcoholic liver disease (ALD) is a significant global health concern, primarily resulting from chronic alcohol consumption, with oxidative stress as a key driver. The ethyl acetate extract of (CGE) exhibits antioxidant and hepatoprotective properties, but its detailed mechanism of action against ALD remains unclear. This study investigates the effects and mechanisms of CGE in alleviating alcohol-induced oxidative stress and liver injury.

Background/objectives: Hyperlipidemia is a serious risk factor for cardiovascular diseases and liver steatosis. In this work, we explored the effect of an herbal formula (CBF) containing immature pods and extracts on lipid metabolism disorders and lipoprotein-rich plasma (LRP) oxidation in mice.
Methods: The phenolic composition was determined using HPLC-DAD analysis.

The large-scale implementation of 2D material-based membranes is hindered by mechanical stability and mass transport control challenges. This work describes the fabrication, characterisation, and testing of self-standing graphene oxide (GO) membranes cross-linked with oxides such as FeO, AlO, CaSO, NbO, and a carbide, SiC. These cross-linking agents enhance the mechanical stability of the membranes and modulate their mass transport properties.

This study investigated the protective effect of Dai Bai Jie (DBJ) extract against acute alcoholic liver injury (AALI) and elucidated its potential mechanism. The total saponin level in the DBJ extracts was measured using vanillin-chloroform acid colorimetry. To observe the preventive and protective effects of DBJ on AML-12 cells in an ethanol environment, the effective components of DBJ were identified.
