Roles of niobium pentoxide, vanadium pentoxide and titanium dioxide in the grain growth and sintering of uranium dioxide
Pure uo2 sinters readily at temperatures below 1600°c when non-stoichiometric oxygen introduced during the presintering treatment is available for diffusion and subsequent densification. In the absence of excess oxygen sintering occurs at temperatures above 1600°C by self-diffusion of stoichiometric oxygen in uo2 • Grain growth occurs when open porosity has been eliminated and is controlled by ...
متن کاملSynthesis and electrochemical properties of niobium pentoxide deposited on layered carbide-derived carbon
Nb2O5 nanoparticles were hydrothermally deposited on carbidederived carbon (CDC). Addition of phenylphosphonic acid affects the particle size and
متن کاملInfluence of niobium pentoxide addition on the properties of glass ionomer cements
Objective: To determine the influence of niobium pentoxide (Nb2O5) addition on the physical and chemical properties of glass ionomer cements (GICs). Materials and methods: Five, 10 or 20 wt.% of Nb2O5 were incorporated into commercial GICs (Maxxion R, Vitro Molar, Vitro Fil R) and one group of each GIC remained without Nb2O5 (control groups). The GICs were evaluated by Knoop hardness, compressi...
متن کاملNiobium pentoxide: a promising surface-enhanced Raman scattering active semiconductor substrate
Surface-enhanced Raman scattering technique, as a powerful tool to identify the molecular species, has been severely restricted to the noble metals. The surface-enhanced Raman scattering substrates based on semiconductors would overcome the shortcomings of metal substrates and promote development of surface-enhanced Raman scattering technique in surface science, spectroscopy, and biomedicine st...
متن کاملSolar-microbial hybrid device based on oxygen-deficient niobium pentoxide anodes for sustainable hydrogen production.
Hydrogen gas is emerging as an attractive fuel with high energy density for the direction of energy resources in the future. Designing integrated devices based on a photoelectrochemical (PEC) cell and a microbial fuel cell (MFC) represents a promising strategy to produce hydrogen fuel at a low price. In this work, we demonstrate a new solar-microbial (PEC-MFC) hybrid device based on the oxygen-...
