Functionally graded metal-ceramic composite was fabricated by pressure-less sintering. The pure metallic component (Ti) and the pure ceramic component (HA) were located at the ends of a cylindrical specimen. Titanium and-Hydroxyapatite were utilized as a metallic and ceramic layer. The target sample thickness was 6 mm with radius cylindrical 20 mm. The sample was made from the cylindrical type ...

A rough surface texture was found on laser sintered titanium substrate, which was responsible for instability of the calcium phosphate layer from the point of view of obtaining good adhesivity to the substrate at given preparation conditions. After the mechanical treatment and following soaking of Ti substrate in 3 M NaOH solution, the surface texture was much smoother than in the original samp...

The coordination chemistry of oxotitanium(IV) or titanyl(IV), TiO2+, has been studied in solution by X-ray methods. The titanyl(IV) ion hydrolyzes easily in aqueous systems to solid titanium dioxide as long as it is not stabilized through complexation. In this study the structures of the hydrated bissulfatotitanyl(IV) complex and the dimethylsulfoxide (DMSO) solvated titanyl(IV) ions have been ...

The use of metals and their alloys in restorative and implant dentistry dates back to centuries. Titanium (Ti) is one of the most widely used biomaterial for medical implants because of its excellent mechanical properties and exceptional biocompatibility. The good biocompatibility of Ti is related to the thin oxide layer formed on Ti surface. TiO2 is inactive with the surrounding biological env...

Understanding the dynamical nature of the catalytic active site embedded in complex systems at the atomic level is critical to developing efficient photocatalytic materials. Here, we report, using 4D ultrafast electron microscopy, the spatiotemporal behaviors of titanium and oxygen in a titanosilicate catalytic material. The observed changes in Bragg diffraction intensity with time at the speci...

In this study, catalyst of rutile titanium dioxide nanoparticles (rTiO2-NP) has been investigated for the removal and reduction of unburned hydrocarbons as benzopyran. To evaluate and calculate the thermodynamic properties of this aim, pollutants are closed to the nanoparticles and converted them into other products and the carbon dioxide molecules are simulated in the 12th steps. The geometric...

ABSTRACT The coordination polymer [Ti(OiPr)3(OOCCH2CH2CH2C3N2H3)] n was prepared from 4-(imidazol-1-yl)butyric acid and titanium isopropoxide. The structure of the compound is remarkable, as the carboxylate group is coordinated in a chelating manner and no dimerization of the Ti(OiPr)3 groups through OR bridges was observed. GRAPHICAL ABSTRACT

The title complex, dichlorido[N,N-di-methyl-2-(η(5)-tetra-methyl-cyclo-penta-dien-yl)acetamidinido-κN']titanium(IV), [Ti(C(13)H(20)N(2))Cl(2)], exhibits an unusual ansa-bridged conformation. The cyclo-penta-dienyl ring and the mean plane of the Ti-N=C-C-C fragment form a dihedral angle of 88.08 (11)°.

In a recent study, nanocrystalline Ti-based alloys were synthesized using mechanical alloying (MA) followed by annealing. The alloying elements Nb or Nb and Zr were added to titanium. The mechanical properties and the corrosion resistance of these materials were investigated and compared with microcrystalline Ti and the TiAl6V4 alloy. An enhancement of the properties due to nanoscale structures...
