Article Abstract
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.

Background: Oral squamous cell carcinoma (OSCC) is one of the most frequent head and neck cancers. The 4-nitroquinoline 1-oxide (4NQO) mouse model of oral carcinogenesis is a well-established model to investigate the mechanism behind OSCC development, including epigenetic alterations. Studies have shown that histone acetylation is a key regulator of gene expression and may play a role in such a tumor.
