The aim of this study was to compare the shear bond strengths (SBS) of cast, machined, and laser-sintered titanium to dental porcelain. Two kinds of dental porcelains (Titankeramik and Triceram) were applied on cast (Tritan), machined (DC-Titan), and laser-sintered (EOSINT) titanium specimens (n=10). SBS test was conducted, and fracture surface analysis was also performed to determine the failu...

The disadvantages of allografts to restore femoral bone defects during revision hip surgery have led to the search for alternative materials. We investigated the feasibility of using porous titanium particles and posed the following questions: (1) Is it possible to create a high-quality femoral graft of porous titanium particles in terms of graft thickness, cement thickness, and cement penetrat...

Titanium-silicon alloys have been electrochemically extracted from the multi-component titanium compounds in molten calcium chloride electrolyte. Sintered pressed pellets of titanium-bearing compounds served as the cathode, and the electrochemical experiments were systematically carried out at 900 °C, 3.1 V and 1000 °C, 3.8 V using a graphite-based anode and an improved inert-oxygen-ion-conduct...

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 ...
