Titanium Sheet Fabricated from Powder for Industrial Applications
In collaboration with Ametek and Commonwealth Scientific and Industrial Research Organization (CSIRO), Oak Ridge National Laboratory has evaluated three different methods for converting titanium hydride-dehydride (HDH) powder into thin gauge titanium sheet from a roll-compacted preform. Methodologies include: sintering, followed by cold rolling and annealing; direct hot rolling of the rollcompa...
متن کاملPhotocatalytic Removal of Pseudomonas Aeruginosa from Water Using Titanium Dioxide Nanoparticles and UV Irradiation
Background: Titanium dioxide (TiO2)-mediated photocatalysis has been found to be an efficient method of water treatment and is capable of degrading a wide range of organic pollutants and microbial agents with high efficiency. The microorganism Pseudomonas aeruginosa is resistant to chemicals and UV irradiation. Bacteria which are resistant to UV-induced oxidative damage of the cell membrane are...
متن کاملVisible-light Photocatalyst - Nitrogen-doped Titanium Dioxide -
A new photocatalyst, known as nitrogen-doped TiO2 (TiO2-xNx), yielding high reactivity under visible light irradiation, together with high potential for mass-productivity, has been developed by using a highly time-efficient development technique that combines computational materials design with experimental syntheses. Under visible light irradiation, TiO2-xNx films and powders exhibit significa...
متن کاملPhotohydrogenation of Acetophenone Using Coumarin Dye-Sensitized Titanium Dioxide under Visible Light Irradiation
The use of coumarin dyes adsorbed on titanium dioxide (TiO2, P25) successfully extended the photocatalytic UV response of TiO2 toward visible light region. The hydrogenation of acetophenone (AP) using TiO2 modified with coumarin dyes proceeded with good chemical efficiencies under visible light irradiation. The role of sacrificial reagents on this dye-sensitized system is also reported.
متن کاملPhotolytic and photocatalytic decolorization of Lauth's violet using nano-titanium dioxide: A kinetics study
Photolysis and photocatalysis of Lauth's violet using nano-titanium dioxide at various aqueous buffer and non-buffer pHs. The effects of some various operating parameters such as initial dye concentration, medium pH, illumination time and catalyst amount have been investigated in a photoreactor equipped with high pressure mercury lamp. Spectrophotometric methods supported that the dye is al...
