In this article the effects of carburizing heat treatment on girth weld with containing titanium oxide and titanium carbide nanoparticles (X-65 grade of gas pipeline) is evaluated. The charpy results show that in the carburized sample containing titanium oxide and titanium carbide nanoparticles compared to the no heat treatment sample (containing titanium carbide and titanium carbide nanopartic...

In recent years, research into materials with high dielectric constants, including doped titanium oxide, has increased because of the potential for modern microelectronics applications and high-density energy storage. The aim of this study was to investigate the effects of zinc oxide as an acceptor additive on the dielectric properties and microstructure of titanium oxide ceramics. The amount o...
Introduction: Occupational exposure to sevoflurane as an anesthetic gases in hospitals, dental clinics and veterinary clinics has been reported in various studies. Considering the harmful effects of sevoflurane anesthetic gas on the health of exposed personnel such as reproductive, preterm delivery and fetal abnormalities and increased spontaneous abortion, it is necessary to remove them from t...
The consequences of zinc oxide (ZnO), Aluminum oxide ( 3 2O Al ) and Titanium oxide (TiO2) on tree growth have been comprehensively investigated in this paper. Zinc oxide (ZnO), II-VI compound semiconductor, is used in varistors in power insulation life. Due to its excellent electrical properties such as nonlinearity of current-voltage (I-V) characteristics, high fast-transient response and hig...
The liquid-phase photocatalytic oxidation of l-octanol in oxygenated acetoniaile on highly dispersed titanium oxide catalysts anchored onto transparent Vycor glass was compared with that obtained on the standard TiO2 powder. The isolated titanium oxide species anchored onto transparent Vycor glass are responsible for its high photocatalytic activity both in the present liquid-phase oxidation of...
Titanium and titanium alloys are currently accepted as the gold standard in dental applications. Their excellent biocompatibility has been attributed to the inert titanium surface through the formation of a thin native oxide which has been correlated to the excellent corrosion resistance of this material in body fluids. Whether this titanium oxide layer is essential to the outstanding biocompat...
In this study, titanium oxide nanotubes anodized on threedifferent surface morphologies of titanium foils, were investigated. AFM imagesis used to show different surface roughness of these foils. Nanotubes wereanodized on titanium foils with 1) no polishing process (A sample), 2)electropolishing process (B sample) and 3) electropolishing process in ethanolicelectrolyte (C sample). To study the ...
True n-type doping of titanium oxide without formation of midgap states would expand the use of metal oxides for charge-based devices. We demonstrate that plasma-assisted fluorine insertion passivates defect states and that fluorine acts as an n-type donor in titanium oxide. This enabled us to modify the Fermi level and transport properties of titanium oxide outside the limits of O vacancy dopi...
Titanium dioxide-nickel oxide porous coatings were synthesized by Plasma Electrolytic Oxidation (PEO)/ ElectroPhoretic Deposition (EPD) in one step and within a short time. The main purpose of this research was to increase photocatalytic activity of titanium oxide by increasing surface area and coupling of titanium oxide with nickel oxide. Applied voltage effects on phase structure, surface mor...
