Biomass Assisted Synthesis Of Antibacterial Gold Nanoparticles And Commentary On Its Future Potential And Applications In Medicine, Chad Willis
Mahurin Honors College Capstone Experience/Thesis Projects
Xylose is a natural monosaccharide found in biomass such as straw, pecan shells, cottonseed hulls, and corncobs. Using this monosaccharide, we report the green synthesis and characterization of biocompatible, biodegradable xylose encapsulated gold nanoparticles (Xyl-GNPs) with potential antibacterial activity. GNPs were synthesized using the bioreduction property of xylose on the chloroaurate anions in an aqueous solution at room temperature and at atmospheric pressure. The characterization of synthesized GNPs was examined by UV-vis spectroscopy; transmission electron microscopy (TEM), energy-dispersive x-ray spectroscopy (EDS) and fourier transform infrared spectroscopy (FTIR). Results indicate that the particles were stable; near spherical in shape with an …
Streaming Fish Sampling: Abundance Versus Biomass Measurements And Determining A Minimum Number Of Years To Sample, Sarah B. Vied
Streaming Fish Sampling: Abundance Versus Biomass Measurements And Determining A Minimum Number Of Years To Sample, Sarah B. Vied
Mahurin Honors College Capstone Experience/Thesis Projects
Abundance and biomass are commonly used for estimating stream fish assemblage and community structure, yet questions arise whether one measurement contains more information about an assemblage and how long sampling should be. Principal component loadings derived from fish biomass measurements taken from Buck Creek in Allen County Kentucky were statistically compared to corresponding measures of abundance to test for significant differences in the two data sets. A sliding window analysis based on abundance was used to determine the minimum number of years a stream should be sampled. Abundance and biomass were not found to be significantly different; correlations of the …
