This study was conducted to evaluate the effect of titanium dioxide and titanium oxide foliar application during two growing stage on growth and forage production of maize during 2012 growing season in the research farm of Islamic Azad University of Varamin-Pishva Branch. The experimental design was randomized complete blocks arranged in factorial with four replications. The factors were includ...

Ultrasonic force microscopy has been applied to the characterization of titanium nitride coatings deposited by physical vapor deposition dc magnetron sputtering on stainless steel substrates. The titanium nitride layers exhibit a rich variety of elastic contrast in the ultrasonic force microscopy images. Nanoscale inhomogeneities in stiffness on the titanium nitride films have been attributed t...

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...

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...
