Abstract (300 words maximum)

Cerium Oxide nanoparticles have been of interest for many years due to its possible applications as an antioxidant that give it properties to scavenge toxic radicals found in neurodegenerative diseases, Cancer, Alzheimer’s, and inflammatory conditions. What gives Cerium Oxide nanoparticles their antioxidant property is the coexistence and Ce3+ and Ce4+. Cerium has two partially filled subshells that allow for several excited states. Our research group has created a soluble sodium borate glass composition doped with varying amounts of Cerium(IV) Oxide and melted to extract Cerium Oxide nanoparticles with different ratios of Ce3+/Ce4+. A previous TEM investigation confirmed the presence of the multivalent cerium oxide nanocrystals on the extracted nanoceria. This current study investigates the FTIR spectrum of the glass and extracted nanoceria using different extraction mechanisms. Nanoceria is acquired from the glassy substrate and the results show a clear O-Ce-O along with Ce-O-Ce stretching vibration bonds in the extracted nanoceria in comparison to the nanoceria-containing glass. EDX analysis has been conducted to confirm the presence of any residual compounds still left after washing.
