Gold nanoparticles were prepared by sol immobilization (AuSI) or deposition precipitation (AuDP), then deposited on NiO and commercial TiO₂ (P25). The Au/NiO catalysts showed higher activity and yield to the secondary amine, compared to Au/TiO₂ catalysts, when tested for the reductive amination of benzyl alcohol with isopropylamine. We attribute this result to a synergistic effect between Au an...

Nickel oxide nanostructures with different lengths have been easily synthesized by calcining nickel foil after soaking in LiOH solution of different concentrations. The measurements of electrochemical properties of these NiO nanostructures show that different lengths of NiO nanostructures would have different electrochemical properties and the NiO nanowires with the longest length have the larg...

MFI type zeolite membranes were synthesized on two types of supporting materials, alumina (α-alumina) and yttria-stabilized zirconia (YSZ) coated alumina. Membranes were prepared by template-free secondary growth method with multiple growth steps in order to minimize intercrystalline gaps. Gas permeation characteristics, thermal and hydrothermal stability for MFI type zeolite membranes were exa...

The change in conductivity of Fe and Ti implanted if-sputtered layers of yttria-stabilized zirconia (YSZ) was studied as a function of the temperature (400-800 °C) and oxygen partial pressure. In an oxidized state and in the temperature range of 400600 ° C, the conductivity of the Fe implanted YSZ film ( 15 keV, 8 × 10 '6 at.cm 2) was dominated by the n-type electronic conductivity of a thin Fe...

A Gram-stain-positive bacterium, designated strain NIO-1109(T), was isolated from a marine sediment sample from Chorao Island, Goa, India. Phenotypic and chemotaxonomic characteristics and data from phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NIO-1109(T) was related to the genus Exiguobacterium . Strain NIO-1109(T) exhibited >98.0% 16S rRNA gene sequence similar...

Alloying nickel oxide (NiO) with lithium oxide (Li2O) at high Li concentrations may reduce NiO's band gap and expand its use as a light absorber in photocatalytic and tandem dye-sensitized solar cell technologies. In this work, we evaluate the viability of this alloy as a p-type hole transport material. We use embedded cluster models, along with unrestricted Hartree-Fock and complete active spa...

NiO nanoparticles were administered to rat lungs via intratracheal instillation or inhalation. During pulmonary toxicity caused by NiO nanoparticles, the induction of oxidative stress is a major factor. Both intratracheal instillation and inhalation of NiO nanoparticles induced pulmonary oxidative stress. The oxidative stress response protein, heme oxygenase-1 (HO-1), was induced by the adminis...
