Electrosprayed Cerium Oxide Nanoparticles

Journal of Electronic Materials, 2018
Cerium 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 ...

Cerium oxide nanoparticles scavenge nitric oxide radical (˙NO)

Chemical Communications, 2012
In 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 ...

Fast Synthesis of Cerium Oxide Nanoparticles and Nanorods

Journal of Nanoscience and Nanotechnology, 2006
The microwave-hydrothermal method has been investigated for the fast synthesis of rare earth cerium oxide (CeO2) nanoparticles and nanorods. This approach combines the advantages of both hydrothermal and microwave heating techniques. It is facile, rapid, energy-saving, and environmentally-benign and leads to high-yields.

Anti‐inflammatory Properties of Cerium Oxide Nanoparticles

Small, 2009
AbstractThe valence and oxygen defect properties of cerium oxide nanoparticles (nanoceria) suggest that they may act as auto‐regenerative free radical scavengers. Overproduction of the free radical nitric oxide (NO) by the enzyme inducible nitric oxide synthase (iNOS) has been implicated as a critical mediator of inflammation.

Synthesis and Characterization of Luminescent Cerium Oxide Nanoparticles

Nanomedicine, 2010
Fluorescent cerium oxide (ceria) nanoparticles were developed through incorporation of erbium into the lattice. Catalytic properties and luminescent behavior are examined.Cerium-erbium mixed oxide nanoparticles were synthesized by the reverse micelles route. Purity, size, and composition were characterized.

Cerium Oxide Nanoparticles: Applications and Prospects in Nanomedicine

Nanomedicine, 2013
Promising results have been obtained using cerium (Ce) oxide nanoparticles (CNPs) as antioxidants in biological systems. CNPs have unique regenerative properties owing to their low reduction potential and the coexistence of both Ce(3+)/Ce(4+) on their surfaces.

Uptake and effects of cerium(III) and cerium oxide nanoparticles to Chlamydomonas reinhardtii

Aquatic Toxicology, 2018
Cerium (Ce) and cerium oxide nanoparticles (CeO2 NP) are increasingly used in different applications. Upon their release into the aquatic environment, the exposure of aquatic organisms becomes likely. In this study, the uptake of CeO2 NP and Ce3+ into the wild type and cell wall free mutant of Chlamydomonas reinhardtii was examined upon short term ...

Synthesis and conductivity of cerium oxide nanoparticles

Materials Letters, 2010
Abstract Cerium oxide (CeO2) nanoparticles have been synthesized through composite-hydroxide-mediated approach. The X-ray powder diffraction (XRD) measurement proved that the pure cubic CeO2 could be obtained at a low temperature region (170–220 °C).

Synthesis and Properties of Cerium Oxide Nanoparticles

Advanced Materials Research, 2011
Cerium oxide(CeO2)nanoparticles were synthesized via a precipitation method using cerous sulfate, ammonia water and cetyl three methyl brominated ammoniu(CTAB) as raw materials. The effect of thermal treatment temperature and dispersing agent on the crystal structure and morphology were discussed.

Cerium Oxide Nanoparticles are More Toxic than Equimolar Bulk Cerium Oxide in Caenorhabditis elegans

Archives of Environmental Contamination and Toxicology, 2013
Engineered cerium oxide nanoparticles (CeO2 NPs) are widely used in biomedical and engineering manufacturing industries. Previous research has shown the ability of CeO2 NPs to act as a redox catalyst, suggesting potential to both induce and alleviate oxidative stress in organisms.
