Electrosprayed Cerium Oxide Nanoparticles
Journal of Electronic Materials, 2018Cerium oxide nanoparticles were fabricated via the calcination of electrosprayed polyvinyl alcohol (PVA)/cerium nitrate nanoparticles. The effect of material variables of PVA/cerium nitrate electrospraying solution, i.e. viscosity, surface tension and electrical conductivity, as well as important process variables like voltage, nozzle–collector ...

Thermodynamic Properties of Cerium Oxalate and Cerium Oxide
Journal of the American Ceramic Society, 1985Differential scanning calorimetry and thermogravimetry were used to determine the thermodynamic properties of cerium oxalate. Hydrated cerium oxalate was found to contain 13 molecules of water and decomposed producing three thermal events corresponding to the loss of adsorbed water, water of hydration, and decomposition of anhydrous cerium oxalate to ...

Cerium Oxide Nanotubes Prepared from Cerium Hydroxide Nanotubes
Advanced Materials, 2005The production of Ce(OH)3 nanotubes, and the formation of CeO2 nanotubes via controlled annealing of the as-formed Ce(OH) 3 nanotubes were discussed. Cerium hydroxide nanotubes was synthesized by hydrothermal treatment of CeCl3 with a 12 M NaOH solution at temperatures ranging from 100 to 150 °C.

Ophthalmic Applications of Cerium Oxide Nanoparticles
Journal of Ocular Pharmacology and Therapeutics, 2020Cerium oxide nanoparticles (CeO2-NPs; or nanoceria) have been largely studied for biomedical applications due to their peculiar auto-regenerative antioxidant activity. This review focuses on ophthalmic applications of nanoceria. Many in vivo data indicate that nanoceria protect the retina from neurodegeneration.

Cerium oxide nanoparticles (nanoceria) are reported to exhibit nanozyme activities, such as biological catalase, oxidase, superoxide dismutase, and peroxidase-mimetic activities. Nanoceria nanozymes own several advantages over natural enzymes, such as controlled synthesis at low cost, tunable catalytic activities, as well as high stability against ...

Cerium oxide nanoparticles scavenge nitric oxide radical (˙NO)
Chemical Communications, 2012In this study we have obtained evidence that cerium oxide nanoparticles (CeO(2) NPs) are able to scavenge nitric oxide radical. Surprisingly, this activity is present in CeO(2) NPs with a lower level of cerium in the 3+ state (CeO(2) NPs with low 3+/4+ ratio and therefore a reduced number of oxygen vacancies), in contrast to the superoxide scavenging ...

Reduction and Sulfidation Kinetics of Cerium Oxide and Cu-Modified Cerium Oxide
Industrial & Engineering Chemistry Research, 2002The reducibility and H2S absorption capacity of cerium oxide and Cu-containing cerium oxide were examined in this work in the temperature range 623−923 K. The sorbents, prepared in bulk oxide form by the urea coprecipitation/gelation method, were composed of a cerium oxide backbone with a small amount of copper (5−40 atom %).

Pharmacological potential of cerium oxide nanoparticles
Nanoscale, 2011Nanotechnology promises a revolution in pharmacology to improve or create ex novo therapies. Cerium oxide nanoparticles (nanoceria), well-known as catalysts, possess an astonishing pharmacological potential due to their antioxidant properties, deriving from a fraction of Ce(3+) ions present in CeO(2). These defects, compensated by oxygen vacancies, are

Nanostructured Cerium Oxide “Ecocatalysts”
MRS Bulletin, 2001Catalysts based on cerium oxide are now used as effective oxidation systems in numerous environmental applications. Cerium oxide was introduced into the catalysis field relatively recently, in 1976, and not as a catalyst initially. Rather, it was chosen as the key oxygen-storage component of the three-way catalyst (TWC) used in automotive exhausts ...
