Literature data about semi-volatile organic compounds in plants and the effect of cerium oxide nanoparticles on them are scarce. Surface modification may change nanoparticle-environment interaction, therefore affects plants. In this research, uncoated glucose-, levan-, pullulan-coated were used for wheat pea treatment during growth. The aim was screening from plants’ shoots using comprehensive ...

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. This leads to increased oxygen mobility within the fluorite CeO2 lattice, leading to the formation of Ce3+ and Ce4+ species and hence doped ceria shows a high propensi...

Nanomaterials are central to nanotechnology and have many useful properties. Cerium(IV) oxide nanoparticles (nCeO) catalytic antioxidant activity, hold promise in industrial medical products. However, the potential biological hazards of nCeO not been addressed. We therefore investigated vivo effects drug interactions nCeO. Tail vein administration did induce liver kidney injury mice but induced...

In this work, the feasibility of employing Cyanex 923 as an extractant into the non-cerium REE (rare earth elements) impurity analysis of high-purity cerium oxide was investigated. Through investigations on the choice of the extraction medium, the optimium extraction acidity, matrix Ce4+ effect on the non-cerium REE ion extraction, the optimium extractant concentration and suitable extracting t...

We present a simple method to gradually tune the size and to induce the shape change of CeO(2) nanoparticles via increasing the content of Yb(3+) doping.

40 Å thick cerium oxide films have been grown on Si 100 substrates via physical vapor deposition of cerium metal in an oxygen background. The films have been characterized for their composition and thermal properties upon deposition and under different annealing conditions via x-ray photoelectron spectroscopy and medium energy ion scattering MEIS and their morphology using atomic force microsco...

This paper presents an investigation on the potential tribological properties of the waterbased cerium dioxide nanofluids. The nanofluids with different nanoparticle concentrations were prepared in a materials laboratory. A stable dispersion of nanoparticles in the fluids was achieved with an appropriate percentage of surfactant sorbitan monostearate. The stability of particle dispersion was st...

In this study, the phytotoxicity of seven metal oxide nanoparticles(NPs)-titanium dioxide (nTiO₂), silicon dioxide (nSiO₂), cerium dioxide (nCeO₂), magnetite (nFe₃O₄), aluminum oxide (nAl₂O₃), zinc oxide (nZnO) and copper oxide (nCuO)-was assessed on two agriculturally significant crop plants (maize and rice). The results showed that seed germination was not affected by any of the seven metal o...
