Commercially-pure titanium (cp-Ti) and the titanium-aluminum-vanadium alloy (Ti6Al4V) are widely used as reconstructive implants for skeletal engineering applications, due to their good mechanical properties, biocompatibility and ability to integrate with the surrounding bone. Electron beam melting technology (EBM) allows the fabrication of customized implants with tailored mechanical propertie...

This study evaluated the effects of fluoride-containing solutions on the surface of commercially pure titanium (CP Ti) obtained by casting. CP Ti specimens were fabricated and randomly assigned to 5 groups (n=10): group 1: stored in distilled water at 37 +/- 1 masculineC; group 2: stored in distilled water at 37 +/- 1 masculineC and daily immersed in 0.05% NaF for 3 min; group 3: stored in dist...

The title compound, [Ti(C5H5)2(C9H11F12NO4P2)], is a four-membered titanacycle obtained from the reaction of Cp2Ti(η(2)-Me3SiC2SiMe3) and CH3N[P(OCH2CF3)2]2 {N,N-bis-[bis-(tri-fluoro-eth-oxy)phosphan-yl]methyl-amine, tfepma}. The Ti(II) atom is coordinated by two cyclo-penta-dienyl (Cp) ligands and the chelating tfepma ligand in a strongly distorted tetra-hedral geometry. The mol-ecule is locat...

Due to their unique properties, titanium (Ti) and Ti-alloys are particularly suitable for biomedical devices. Ti has a high specific strength low Young’s modulus (reducing stress shielding), corrosion resistance, superior biocompatibility. However, Ti’s moderately (100–110 GPa) is still considerably higher than bones (5–30 GPa). The β-Ti phase, whose elastic closer the bone, can be kept by incr...

The goal for current orthopedic implant research is to design implants that have not only good biocompatibility but also antibacterial properties. TiO2 nanotubes (NTs) were fabricated on the titanium surface through electrochemical anodization, which added new properties, such as enhanced biocompatibility and potential utility as drug nanoreservoirs. The aim of the present study was to investig...

Mechanical properties and microstructures of commercially pure titanium (CP-Ti) developed by a newly designed multi-pass equal channel angular pressing (ECAP) process and cold drawing were investigated. The ECAP apparatus was developed in order to improve the efficiency of common ECAP and the performance of finished products. A much stronger CP-Ti billet was produced by using the proposed proce...

Investigation of the effectiveness of surface treatments that promote a strong bond strength of resin cements to metals can contribute significantly to the longevity of metal-ceramic restorations. This study evaluated the effect of surface treatments on the shear bond strength (SBS) of a resin cement to commercially pure titanium (CP Ti). Ninety cast CP Ti discs were divided into 3 groups (n=30...

Commercial purity titanium (CP-Ti) and a Ti-6Al-4V alloy (Ti64) were processed by high-pressure torsion (HPT) for 10 20 turns. The HPT processing produced nanostructured microstructure significant strength enhancement in the CP-Ti Ti64 samples. After turns, samples of HPT-processed subjected to laser surface treatments an air atmosphere using different scanning speeds powers. roughness laser-mo...

Triggered Inversion (TI) in Hebrew has been previously analyzed as canonical A'-movement to the specificer position of a functional projection in the CP-layer (Doron & Shlonsky 1990, Shlonsky 1997). This article examines the semantic properties of TI constructions in Hebrew, specifically the cross-linguistic similarities between TI in Hebrew and pseudoclefts (PC) in English, as discussed in Hey...
