Seven cerium organometallic systems are studied using both density functional theory and multiconfigurational techniques in order to better understand the oxidation state of the metal in each of these systems. These calculations show that in formally Ce(IV) organometallic systems with electron-rich, carbon-based ligands the total number of Ce 4f electrons is closer to the formal value of a Ce(I...

Understanding and manipulating micelle morphology are key to exploiting surfactants in various applications. Recent studies have shown surfactant self-assembly a variety of Deep Eutectic Solvents (DESs) where both the nature interaction molecule with solvent components influence size, shape, micelles formed. So far, formation has only been reported type III DESs, consisting solely organic speci...

The potential toxicity and accumulation of engineered nanomaterials (ENMs) in agricultural crops has become an area of great concern and intense investigation. Interestingly, although below-ground vegetables are most likely to accumulate the highest concentrations of ENMs, little work has been done investigating the potential uptake and accumulation of ENMs for this plant group. The overall obj...

Nanoceria is used as a catalyst in diesel fuel, as an abrasive in printed circuit manufacture, and is being pursued as an antioxidant therapeutic. Our objective is to extend previous findings showing that there were no reductions of cerium in organs of the mononuclear phagocyte (reticuloendothelial) system up to 30 days after a single nanoscale ceria administration. An ~5% aqueous dispersion of...
