RF sputtering method was used for deposition 70wt% CeO2/TCP thin film on stainless steel 316L surface. The selection of ceria and tricalcium phosphate is according to the fact importance these materials in biomedical media. produced coating characterized by XRD, FESEM/EDS AFM analysis, result revealed that obtained peaks from XRD refer deposited materials. When substitution Ce done, distorting ...

Ceria, zirconia and mixed cerium-zirconium mesoporous oxides were synthesized and 12 used as supports for sulfur and gold species. The materials were characterised using selected 13 advanced techniques (ICP-OES, elemental analysis, XPS, XRD, N2 adsorption and desorption 14 isotherms, UV-vis, ATR-FTIR, TPR-H2, TG-DTA) which allowed monitoring of the oxidation state 15 of metals (cerium and gold)...

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...

Cerium oxide nanoparticles (nanoceria; CNPs) have been found to have both pro-oxidant and anti-oxidant effects on different cell systems or organisms. In order to untangle the mechanisms which underlie the biological activity of nanoceria, we have studied the effect of five different CNPs on a model relevant aquatic microorganism. Neither shape, concentration, synthesis method, surface charge (...
