According to α -amylase enzyme inhibition results, all except 6c (IC50: 2299 μg/mL) found have a higher IC50 value than drug...

Abstract Azo dyes are known to cause environmental pollution and freshwater contamination, posing carcinogenic risks human health. Consequently, researchers have directed their attention towards studying effective methods for removing these from textile effluent. Amorphous alloys emerged as a promising candidate enhancing degradation efficiency on azo dyes, with various metallic undergoing extensive investigation. Notably, the novel catalytic materials exhibit significantly higher...
