Binary and ternary separations of heavy metals, e.g. Zn–Bi, Mn–Pb, Cd–Pb, Mn–Bi–Mo, and Cr–Pb–Bi on columns of titanium(IV) tungstosilicate and Zn–Ni, Mo–Pb, Hg–Pb, Zn–Cr–Bi, and Zn–Ni–Bi on titanium(IV) tungstophosphate, have been demonstrated. The adsorption and elution of important metal ions such as Mo, Al, and As on titanium(IV) tungstosilicate and Hg, Fe, and Cr on titanium(IV) tungstopho...

Titanium salts are widely used in pharmacy and industry as intensely white permanent pigment with good covering power in paints , paper , toothpaste , plastics and food dye s. This ion is a redox-active transition metal and may cause oxidative damages to lipids, proteins and DNA molecules. In spite of abundant literature, questions about the side effects of titanium ions...

Long titanium aneurysm clips have recently been released. In the present study, comparative study of long titanium and cobalt alloy clips was performed. Two kinds of Sugita long clips (straight clips of 25- and 35-mm blade length) made of titanium and cobalt alloys were tested by measuring the closing force, the anti-scissoring torque, and the maximum opening width. There were some differences ...

OBJECTIVE Mechanical techniques, including scaling with metal, plastic, or ultrasonic instruments, rubber cup polishing, air-powder abrasive system and brushing with a conventional or a rotating brush, have been used for the debridement of dental implants. Recently, rotating brushes with titanium bristles (titanium brush) have been introduced for the debridement of implant surface when peri-imp...

In this paper, AISI 441 stainless steel was investigated as a casting using the investment process (ICP). The microstructure and mechanical properties of as-cast normalizing treatment samples were analyzed. results show that tensile strength prepared by ICP is 458 MPa, elongation 22.7%. Normalizing can improve performance ICP, but have slightly decreasing trend with increasing temperature time....

Ag-implanted titanium with a nanostructured surface was prepared by hydrothermal treatment with H(2)O(2) followed by Ag plasma immersion ion implantation. Streptococcus mutans, Porphyromonas gingivalis and Candida albicans were chosen for antimicrobial tests. Genes related to microbial structure or adhesion, namely glucan-binding proteins B (GbpB), fimbria protein A (FimA), and agglutinin-like ...

Biomedical implants made of titanium-based materials are expected to have certain essential features including high bone-to-implant contact and optimum osteointegration, which are often influenced by the surface topography and physicochemical properties of titanium surfaces. The surface structure in the nanoscale regime is presumed to alter/facilitate the protein binding, cell adhesion and prol...

A series of titanium trichloride complexes , ligated with claw-type tetradentate aminophenolate ligands were synthesized from the direct reaction of TiCl4(THF)2 with 1 equiv. of the corresponding aminophenol in the presence of triethylamine. For comparison purposes, titanium isopropoxide complexes were also synthesized via the reaction of Ti(O(i)Pr)4 and 1 equiv. of the proligand. Similar react...

Molecular dynamics simulations of titanium dioxide nanoparticles in the three commonly occurring phases (anatase, brookite, and rutile) are reported. The structural properties inferred by simulated X-ray diffraction patterns of the nanoparticles were investigated. The titanium-oxygen bond length as a function of size, phase, and temperature was determined and was found to be dependent on the co...
