It is demonstrated that Cu nanostructures fashioned by oblique angle deposition (OAD) of gaseous Cu atoms onto CaF2 substrates have SEIRA enhancement factors that are close to par with Ag or Au nanostructures formed using vapor deposition at a normal deposition angle. Cu nanostructures grown at normal angle show about 5× in SEIRA enhancement of a p-nitrobenzoic acid (PNBA) monolayer and have a range...
Wastewater from swine confined-housing operations contains elevated levels of copper and zinc due to their abundance in feed. These metals may accumulate to phytotoxic levels in some agricultural soils of North Carolina due to land application of treated swine effluent. We evaluated fungi for their ability to remove these metals from wastewater and found Aspergillus niger best suited for this purpose...
