Chris Woan, USA (East) finalist

Chris Woan spent most of his life in Florida and graduated from the University of Florida with a BS in Materials Science and Engineering. In 2004, Woan worked at Los Alamos National Laboratory on the thermodynamic modeling of nuclear fuels.

This cemented his desire to continue with graduate studies. He is currently working on doctoral research to develop novel metal oxide antioxidants. Woan is also heavily involved in a program to enhance the learning of junior high school students through inquiry-based science laboratory experiments.

The Materials Science of Metal Oxide Nanoparticle Antioxidants

We are coming upon an era where permanent toxin-mediating treatments are being developed. One such system results from the interdisciplinary research into therapeutic nanoparticles which address medical maladies with high potency.

Cerium-based metal oxide nanoparticles exhibit antioxidative properties neutralising the presence of harmful reactive oxidative species in biological systems. These reactive oxidative species play a major role in the progression of diseases, from breast cancer and macular degeneration to diabetes, and even general aging. The use of simple materials science concepts of catalysis and solid solutioning can help develop enhanced high-potency free radical reducing nanoparticles.

This lecture examines the basis of the research for enhanced metal oxide treatments, discussing what has been completed, and presents the current challenges this research is addressing.
