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.

Background: Currently, protein-polyphenol complexes have garnered increasing attention as surface-active substances in high internal phase Pickering emulsions (HIPPEs). However, the effects of the oil type and flavonoid structure on the HIPPE-stabilizing ability of protein-polyphenol complexes remain unclear. Notably, very few studies have investigated the impacts and mechanisms of different oils (olive, flaxseed, and coconut oils) and the effects of the addition of flavonoids (catechin and quercetin) on the interfacial behavior of walnut protein hydrolysates (WPHs) and the co-oxidation of protein-lipid in the resulting emulsion during storage.

Mangrove fungi in action: Novel bioremediation strategy for high-chloride wastewater.

Bioresour Technol

December 2024

Agricultural Products Processing Research Institute, Chinese Academy of Tropical Agricultural Sciences, Zhanjiang, China. Electronic address:

Bioremediation of extremely high-chloride wastewater poses significant challenges due to the adverse effects of elevated salt concentrations on most microorganisms, where chloride levels can be as high as 7% (w/v). Mangrove wetlands derived fungus, Aspergillus aculeatus, emerged as a promising candidate, capable of removing approximately 40% of chloride ions in environments with concentration of 15% (w/v), representative of industrial wastewater conditions. Transcriptomics and biochemical assays conducted under increasing salt conditions revealed that elevated chloride concentrations induce the expression and activity of S-adenosyl methionine-dependent methyltransferase, which facilitates the conversion of chloride into chloromethane.
