In this study, we introduce an synthesis technique for incorporating gold nanoparticles (AuNPs) into a magnetic nanocomposite made of glucosamine and alginate (GluN/Alg) ionotropic gelation. GluN acted as a reducing agent for gold ions, leading to the formation of AuNPs which embedded in the nanocomposite FeO@GluN/Alg. Analytical techniques confirmed the crystallite structure of the nanocomposite AuNPs/FeO@GluN/Alg, which had an average size of 30-40 nm.

We aimed to compare current anxiety or depression rates to those before and during the first year of the pandemic and to evaluate demographic differences.
Methods: We analyzed Household Pulse Survey data prospectively collected from a representative U.
Context: Lighting conditions significantly influence visual acuity (VA), visual function, and quality of life. Previous research highlighted a correlation between luminance and VA but left a gap in understanding the impact of surrounding luminance. This study focused on investigating the effects of both central and peripheral luminance on VA.
