Cerium, neodymium and gadolinium contain double beta active isotopes. The most interesting are Nd and Gd (promising for 02 search), Ce (2 candidate with one of the highest Q2). The main problem of compounds containing lanthanide elements is their high radioactive contamination by uranium, radium, actinium and thorium. The new generation 2 experiments require development of methods for a de...

Cerium nanopowders doped by a small amount of silver exhibit interesting catalytic properties towards the low temperature oxidation of CO. It is generally believed that a metal support interaction plays an important role in a catalytic process. Therefore in our study we examined electronic and adsorption properties of cerium deposited onto a polycrystalline silver substrate. Layers of approxima...

The life threatening disease of sepsis is associated with high mortality. Septic patient survivability with currently available treatments has failed to improve. The purpose of this study was to evaluate whether lipopolysaccharide (LPS) induced sepsis mortality and associated hepatic dysfunction can be prevented by cerium oxide nanoparticles (CeO2NPs) treatment in male Sprague Dawley rats. Here...

Ce2[MoO5][MoO4] crystallizes monoclinically in space group P21/c (a = 2241.98(9), b = 712.95(3), c = 2044.19(8) pm, β = 116.936(2)◦ , Z = 16). Besides eight crystallographically different Ce3+ cations with coordination numbers ranging from seven plus one to ten, its structure contains two isolated oxomolybdate(VI) species, namely [MoO4]2− tetrahedra and [MoO5]4− trigonal bipyramids and square p...

Boron- and cerium-codoped TiO2 photocatalysts were synthesized using modified sol-gel reaction process and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), particle size distribution (PSD), diffuse reflectance spectra (DRS), and Brunauer-Emmett-Teller (BET). The photocatalytic activities were evaluated by monitoring the degradation of dye Acid Red B (ARB). The r...

The promotion of Ag–ZSM-5 by cerium for the selective catalytic reduction (SCR) of NO with methane in the presence of an excess of oxygen was studied in this work. Ce–Ag–ZSM-5 catalyzes the CH4-SCR of NOx over the temperature range of 450–600◦C. Rate measurements of NO reduction to N2 under SCR conditions and of the competing CH4 oxidation by O2 (CH4 combustion) show that incorporation of a sma...

In this paper, the adsorption of cerium on modified Mesoporous aluminosilicate (with Si/Al mole ratio of 10) was studied. The effects of pH, contact time, initial concentration of cerium on adsorption of cerium were investigated. The adsorption capacity was high in the pH range of 4-8 and decreases with decreasing of the pH value. The Langmuir and Freundlich isotherms were applied to represent ...

The ultra-precision diamond cutting process exhibits strong size effects due to the ultra-small depth of cut that is comparable with the cutting edge radius. In the present work, we elucidate the underlying machining mechanisms of single crystal cerium under diamond cutting by means of molecular dynamics simulations, with an emphasis on the evaluation of the effect of depth of cut on the cuttin...

Nanoparticles of palladium-doped cerium oxide (Pd–CeO2) have been prepared by aqueous co-precipitation resulting in a single phase cubic structure after calcination according to X-ray diffraction (XRD). Inhomogeneous strain, calculated using the Williamson–Hall method, was found to increase with palladium content, and the lattice contracts slightly, relative to nano-cerium oxide, as palladium c...
