Decontamination of metal surfaces contaminated with low levels of radionuclides is a major concern at Department of Energy facilities. The development of an environmentally friendly and cost-effective decontamination process requires an understanding of their association with the corroding surfaces. We investigated the association of uranium with the(More)
Speciation of uranium in cultures of Clostridium sp. by X-ray absorption near-edge spectroscopy (XANES) at the National Synchrotron Light Source and by X-ray photoelectron spectroscopy (XPS) showed that U(V1) was reduced to U(1V). In addition to U(IV), a lower oxidation state of uranium, most probably U(III), was detected by XANES in the bacterial cultures.(More)
Using a simple chemical process, phosphorylcholine has been deposited covalently on the surface of a variety of hydroxylated polymers as a stable, monomolecular coating. Our goal was to obtain new biomaterials which, due to the chemical similarity of the modified interfaces to the phospholipid head groups present on the extracellular surfaces of blood cell(More)
Ion implantation is emerging as a powerful and unique approach to corrosion protection. Several studies have demonstrated that the corrosion resistance of a number of ferrous and nonferrous commercial grade engineering alloys can be improved by ion implantation with suitable elements. This paper will review recent studies carried out in this laboratory and(More)
Novel methods were developed to generate and characterize surface structures formed from polymer segregation within a powder coating system. A blend of unique acrylic polyol resins and low concentrations of matting agent afforded a durable coating exhibiting consistent low reflectance. An enhanced synergistic effect was observed from the phase separation(More)
