The Anodic Oxidation of Vanadium in Phosphoric Acid Solution

The purpose of this thesis was to analyze the possibility of recovering the vanadium in the phosphoric acid by anodic oxidation in an electrolytic cell. This problem allowed not only the possibility of improving a commercial operation, but a study of the functioning of an interesting and very important phenomena.

A Rapid Determination of Small Amounts of Lead in Zinc

This investigation, carried on in the metallur­gical laboratories at the Montana School of Mines, was undertaken with the desire to work out a rapid method for the estimation, or the determination, of the amount of lead in zinc.

Colloidal Nano-apatite Particles with Active Luminescent and Magentic Properties for Biotechnology Applications

Colloidal Nano-apatite Particles with Active Luminescent and Magentic Properties for Biotechnology Applications. The synthesis of functional nano-materials is a burgeoning field that has produced remarkable and consistent breakthroughs over the last two decades. Individual particles have become smaller and shown potential for well defined functionality. However, there are still unresolved problems, a primary one being the loss of functionality and novelty due to uncontrolled aggregation driven by surface energy considerations. As such the first design criteria to harness the true potential of nanoparticles is to prevent unwanted agglomeration by: (1) improving, and, if possible, (2) controlling aggregation behavior. This requires specific knowledge of the chemistry of the immediate locale of the intended application; especially for biologically relevant applications. The latter criterion is also application driven but should be considered, generally, to diversify the range of functional properties that can be achieved. We have now reason to believe that such a novel system with multifunctional capabilities can be synthesized rather conveniently and have far reaching impact in biotechnology and other applications in the near future. We are presently experimenting with the syntheses of spheroidal, metal-doped, colloidal apatite nano-particles (~10 nm) for several potential biomedical applications.
