The title dinuclear half-sandwich complex, [CpTi(OCH=CH2)(μ2-N-iPr)]2 (Cp = cyclo-penta-dien-yl; iPr = isopropyl), was ob-tained from the reaction of Cp2TiCl2, n-butyl-lithium and iso-propyl-amine in tetra-hydro-furan. Each Ti(IV) atom is coordinated by one Cp ligand, one vin-yloxy unit and two bridging imido groups in a strongly distorted tetra-hedral geometry. There are two half mol-ecules in...

Atomic layer deposition (ALD), a method that allows the formation of thin and conformal films on substrates interest, was employed to prepare alumina (Al2O3) hafnia (HfO2), with aim protecting surface commercially pure titanium (cp-Ti) used in biomedical applications. Prior deposition, cp-Ti specimens have been prepared two ways – grinding followed by polishing. Such surfaces denoted as rough s...

The titanium complex Cp[1,3-(2',6'-Me2C6H3)2(CH2N)2C=N]Ti(CH2Ph)2, with a monoanionic eta 1-iminoimidazolidide ancillary ligand, is shown to be a highly efficient catalyst for olefin polymerisation when activated with the Lewis acid B(C6F5)3.

UNLABELLED The interest in using titanium to fabricate removable partial denture (RPD) frameworks has increased, but there are few studies evaluating the effects of casting methods on clasp behavior. OBJECTIVE This study compared the occurrence of porosities and the retentive force of commercially pure titanium (CP Ti) and cobalt-chromium (Co-Cr) removable partial denture circumferential clas...

We begin with a short review on the motivation of our problem making reference to the works [5], [10] where one can find precise definitions of the notions below. At first, we consider a k− dimensional Frobenius manifold F with flat coordinates (t1, · · · , tk)∈ F where the coordinate ti corresponds to coefficients of the basis ∆i of the quantum cohomology H ∗(CP). On H∗(CP) one can define so c...

Cp-Ti is the most common material used for dental implants, but its elastic modulus is around five times higher than that of bone. Recently, promising alloys that add Nb, Ta, Zr and Mo to Ti have been developed. The mechanical properties of these alloys are directly related to its microstructure and the presence of interstitial elements, such as oxygen, carbon, nitrogen and hydrogen. In this st...

The paper compares the coatings produced by plasma electrolytic oxidation (PEO) on commercially pure titanium and a novel superelastic alloy Ti-18Zr-15Nb (at. %) for implant applications. PEO were both alloys in identical pulsed bipolar regime. properties of examined using scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive spectroscopy (EDX), potentiodynamic polariza...
