Nano-sized titanium dioxide TiO2 powder was prepared by new wet chemical route from its precursor Titanium (IV) chloride (TiCl4) as precursor with isopropoxy alcohol in presence of nitric acid under ambient condition. Their morphologies, phase compositions and components of the TiO2 nanoparticles were characterized by transmission electron ...

Cerium oxide (ceria, CeO 2-x where x is 0 to 0.5) has been one of the most widely used heterogeneous catalysts particularly in three way catalytic converters. Most of the catalytic traits can be attributed to two properties of ceria: first, the high mobility and storage capacity of oxygen within the lattice; second, the ease with which cerium changes between Ce 3+ and Ce 4+ states. These proper...

Calcined coke is a competitive material for making carbon anodes for smelting of alumina to aluminum. Calcining is an energy intensive industry and a significant amount of heat is exhausted in the calcining process. Efficiently managing this energy resource is tied to the profit margin and survivability of a calcining plant. To help improve the energy efficiency and reduce natural gas consumpti...

One-dimensional (1D) nanostructures of ternary complex oxides have drawn intensive interest because of their novel size-dependent properties, such as ferroelectric,1a multiferroic,1b and superconductivity.1c Various synthetic approaches, such as aqueous route by employing hydrothermal reaction2 or templates,3 molten-salt synthesis,4 and composite-hydroxide-mediated synthesis5 have been develope...

Gas-phase photocatalysis using titanium dioxide (TiO2) has been regarded as an attractive technology for the control of VOC emissions. However, TiO2 requires ultraviolet irradiation exceeding the bandgap energy of 3.0 eV (wavelength < 400 nm), hence effectively eliminating the utilization of solar and interior lighting as a source of photo-activation energy. Recently, a number of studies have d...

High-pressure resistivity and X-ray diffraction measurements were conducted on La0.85MnO3 d at 6 and 7 GPa, respectively. At low pressures the metal–insulator transition temperature (TMI) increases linearly up to a critical pressure, P 3.4 GPa, followed by reduction in TMI at higher pressure. Analysis of the bond distances and bond angles reveals that a bandwidth increase drives the increase in...

Many agrowastes are being used for energy production by combustion in thermal power plants. This process generates huge amounts of ashes, which have a potential pozzolanic activity for blending with Portland cement or hydrated lime. Elephant grass (Pennisetum purpureum) and corn straw (Zea mays) are two types of biomass whose ashes could be valorized in construction materials. The aim of the pr...

Anodes for solid oxide fuel cells (SOFCs) have been prepared by electrodeposition of either Co or Ni into a layer of porous yttria-stabilized zirconia (YSZ), 60 μm thick. The YSZ, having 65% porosity, was prepared by tape casting with graphite pore formers and was attached to the dense YSZ electrolyte. After adding 10 vol % CeO2 by impregnation of aqueous solutions of CeNO3)3, followed by calci...
