Mechanical properties of ceria nanorods and nanochains; The effect of dislocations, grain-boundaries and oriented attachment [PDF]

, 2011
We predict that the presence of extended defects can reduce the mechanical strength of a ceria nanorod by 70%. Conversely, the pristine material can deform near its theoretical strength limit.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

Advanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Nickel-doped ceria nanoparticles : the effect of annealing on room temperature ferromagnetism [PDF]

, 2015
Nickel-doped cerium dioxide nanoparticles exhibit room temperature ferromagnetism due to high oxygen mobility within the doped CeO2 lattice. CeO2 is an excellent doping matrix as it can lose oxygen whilst retaining its structure.

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

A flexible one-pot route to metal/metal oxide nanocomposites [PDF]

, 2010
We report a one-pot route to Au/CeO2 nanocomposites. A readily-available biopolymer, sodium alginate, is exploited for controlled formation and stabilisation of gold nanoparticles followed by in situ growth of a sponge-like network of CeO2 nanoparticles.

Unlocking the Full Potential of Zinc Oxide/Cerium Oxide Composite Nanoparticles for Removal of Mixed Pharmaceutical and Dye Pollutants in Water

Advanced Materials Interfaces, EarlyView.
ZnO/CeO2 composite nanoparticles synthesized via a facile hydrothermal method simultaneously degrade ciprofloxacin, tetracycline, methylene blue, and methyl orange in a four‐component mixture under UV irradiation. The Ce3+/Ce4+ redox cycling and oxygen vacancies at the ZnO/CeO2 interface suppress charge recombination and enhance reactive species ...

Antibacterial Activity of Polymer Coated Cerium Oxide Nanoparticles

PLoS ONE, 2012
Cerium oxide nanoparticles have found numerous applications in the biomedical industry due to their strong antioxidant properties. In the current study, we report the influence of nine different physical and chemical parameters: pH, aeration and, concentrations of MgSO(4), CaCl(2), KCl, natural organic matter, fructose, nanoparticles and Escherichia ...
