In recent years, nanostructured Au catalysts have attracted a lot of attention as potential candidates for the removal of poisonous carbon monoxide from synthesis gas streams, thus upgrading hydrogen gas to be used as fuel at the anode of lowtemperature fuel cells. The interest in Au nanoparticles has been motivated by the pioneering work of Haruta et al., who demonstrated the extremely high ac...
Solar-driven thermochemical routes enable storage of solar energy in chemical form for off-sun use by means synthetic fuel production. Here, we explore vanadium-doped ceria materials partial oxidation methane, followed an efficient splitting CO2 and H2O into syngas. The primary role the dopant is to enhance optimize cycle capacity at low isothermal temperatures. intake lattice reached its satur...
Engineered nanoscale ceria is used as a diesel fuel catalyst. Little is known about its mammalian central nervous system effects. The objective of this paper is to characterize the biodistribution of a 5-nm citrate-stabilized ceria dispersion from blood into brain and its pro- or antioxidant effects. An approximately 4% aqueous ceria dispersion was iv infused into rats (0, 100, and up to 250 mg...
Mo, Cu-doped CeO2 (CMCuO) nanopowders were synthesized by the nitrate-fuel combustion method aiming to improve electrical and electrochemical properties of its Mo-doped (CMO) parent addition copper. An conductivity ca. 1.22·10â2 S cmâ1 was measured in air at 800°C for CMCuO, which is nearly 10 times higher than that reported CMO. This increase associated with inclusion copper into crystal...
PURPOSE Ceria engineered nanomaterials (ENMs) have current commercial applications and both neuroprotective and toxic effects. Our hypothesis is that ceria ENMs can associate with brain capillary cells and/or cross the blood-brain barrier. METHODS An aqueous dispersion of ∼5 nm ceria ENM was synthesized and characterized in house. Its uptake space in the Sprague Dawley rat brain was determine...
