The aims of our experiment were to evaluate the uptake and translocation of cerium and titanium oxide nanoparticles and to verify their effects on the growth cycle of barley (Hordeum vulgare L.). Barley plants were grown to physiological maturity in soil enriched with either 0, 500 or 1000 mg · kg(-1) cerium oxide nanoparticles (nCeO₂) or titanium oxide nanoparticles (nTiO₂) and their combinati...

To prevent Cr poisoning of the cathode and to retain high conductivity during solid oxide fuel cell (SOFC) operation, Cu or La doped Co-Mn coatings on a metallic interconnect is deposited and followed by oxidation at 750 ◦C. Microstructure and composition of coatings after preparation and oxidation is analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). High energy micro ...

Hot reformate gas produced by reforming of heavy fuels, such as JP-8, must be desulfurized prior to its use in a solid oxide fuel cell (SOFC). This requires development of sorbent materials with high sulfur absorption efficiency and capacity at the SOFC operating temperature (650-800 C) to avoid heat exchanger penalties. Sorbent performance stability in cyclic operation of sulfidation and regen...

The microstructure and chemical composition of iron phosphate conversion coatings were investigated by surface/cross-sectional observation using FE-SEM/STEM state analysis XPS. As a result, it was suggested that the reaction progressed while surface oxide on base material remained, fine particles components deposited agglomerated to cover surface. upper layer mainly composed phosphate, interfac...

Abstract Cerium oxide nanoparticles have unique catalytic and oxygen storage capacity properties. In this work, the morphology size of cerium were experimentally theoretically investigated. For synthesis nanoparticles, laser ablation method was used. The analysis morphological characteristics performed using transmission electron microscopy. Using molecular dynamics, we reveal limiting dimensio...

In this study, a non-selenized CuInGaSe2 (CIGS) solar device with textured zinc oxide (ZnO) antireflection coatings was studied. The ZnO nanostructure was fabricated by a low-temperature aqueous solution deposition method. With controlling the morphology of the solution-grown tapered ZnO nanorod coatings, the average reflectance of the CIGS solar device decreased from 8.6% to 2.1%, and the ener...

The effect of nanomaterials on biota under realistic environmental conditions is an important question. However, there is still a lack of knowledge on how different illumination conditions alter the toxicity of some photocatalytic nanomaterials. We have investigated how environmentally relevant UV-A exposure (intensity 8.50 ± 0.61 W/m(2), exposure dose 9.0J/cm(2)) affected the toxicity of ceriu...

For the first time, we considered Mn oxide/C60 composites as water-oxidizing catalysts. The composites were synthesized by easy and simple procedures, and characterized by some methods. The water-oxidizing activities of these composites were also measured in the presence of cerium(iv) ammonium nitrate. We found that the nanolayered Mn oxide/C60 composites show promising activity toward water ox...
