Nanoceria (cerium dioxide nanoparticles, CeO2) has a broad range of biological properties including antiviral activity. The hypothesis was that nanoceria can efficacy against coronavirus (coronavirus porcine transmissible gastroenteritis) and potentially target SARS-CoV-2. Transmissible gastroenteritis (TGEV) is the etiologic agent (PTG), highly contagious pig intestinal disease. aim study to d...

La2Zr2O7 (LZO) films were grown on different buffer architectures by radio frequency magnetron sputtering for the large-scale application of YBa2Cu3O7-x (YBCO)-coated conductors. The three different buffer architectures were cerium oxide (CeO2), yttria-stabilized zirconia (YSZ)/CeO2, and CeO2/YSZ/CeO2. The microstructure and surface morphology of the LZO film were studied by X-ray diffraction, ...

ZnO nanoparticles (NPs) have previously been shown to exhibit selective cytotoxicity against certain types of cancerous cells suggesting their potential use in biomedical applications. In this study, we investigate the effect of surface modification of ZnO NPs on their cytotoxicity to both cancerous and primary T cells. Our results show that polyacrylic acid capping produces negatively charged ...

There is a pressing need for information on the mobility of nanoparticles in the complex aqueous matrices found in realistic environmental conditions. We dispersed three different metal oxide nanoparticles (TiO2, ZnO and CeO2) in samples taken from eight different aqueous media associated with seawater, lagoon,river,andgroundwater,andmeasuredtheirelectrophoretic mobility, state of aggregation, ...

Micron-size Ni-base alloy (NBA) powders were mixed with both 1.5 wt.% (hereinafter %) micron-size CeO2 (m-CeO2) and also 1.5% and 3.0% nano-size CeO2 (n- CeO2) powders. These mixtures were coated on low-carbon steel (Q235) by 2.0 kW CO2 laser cladding. The effects on the microstructures, phases and electrochemical corrosion of the coatings upon the addition of m- and n- CeO2 powders to NBA (m- ...

In this study, Pt1Sn1 intermetallic nanoparticles (NPs) on SiO2/CeO2@SiO2 composites were located either SiO2 or CeO2@SiO2, thereby varying the average distance (intimacy) between metal sites and CeOx from “closest” to “nanoscale”. The catalytic performance of these catalysts was compared dual-bed mixtures Pt1Sn1@SiO2 CeO2@SiO2 powders, which provided a “milliscale” sites. Several beneficial ef...

The degradation of a high concentration organic pollutants has long been challenge to water restoration, and the development electro-Fenton catalysis offers practical approach solving this problem. In study, novel catalyst, activated fullerene soot-loaded NiO-doped CeO2 (0.4(0.4NiO-CeO2)-AFS) nanoparticles, was prepared through impregnation 0.4NiO-CeO2 particles soot (AFS). When applied for 200...

DFT+U calculations of CO oxidation by Au13 nanoclusters (NCs) supported on either CeO2 or doped (X-Ce)O2 (X = Au, Pt, Pd, Ti, Ru, Zr) show that doping the CeO2 support accelerates CO oxidation by the Mars-van Krevelen mechanism at the Au-(X-Ce)O2 interface. We find that Au, Pd, Pt, and Ti dopants significantly lower the vacancy formation energy of the CeO2 support and that electron donation fro...

Nanocomposite systems of ceria nanoparticles and Double Walled Carbon Nanotubes (DWNTs) coated with nano-ceria (n-CeO2) were elaborated using a classical sol gel method. Three samples noted as [n-CeO2 + xDWNTs] with variable weight fractions x=0, 5 and 15wt.% of DWNTs were obtained. The samples were characterized by X-ray diffraction and electron microscopy. The electrical conductivity of [n-Ce...
