OBJECTIVES In this study on 90 individuals we aimed at evaluating the microRNAs (miRNAs) expression profile associated with personal levels of Titanium (Ti) and Zirconium (Zr) traced in hair samples. Ti and Zr materials are broadly used for dental implants but the biological reactions triggered by a long term presence of these materials in the oral cavity still need to be assessed. MiRNAs are m...

The superconducting high-entropy alloys (HEAs) recently attract considerable attention due to their exciting properties, such as the robustness of superconductivity against atomic disorder and extremely high pressure. well-studied crystal structure HEAs is body-centered cubic (bcc) containing Nb, Ti, Zr atoms. same elements are contained in $$\mathrm {Al}_{5}\mathrm {Nb}_{24}\mathrm {Ti}_{40}\m...

In this chapter, a novel titanium (Ti) alloy and foam suitable for biomedical applications will be introduced. As we know, Ti and its alloys are widely used as biomaterials especially for orthopedic implants in load bearing sites as dental and orthopedic implants and heart valves, due to their high mechanical properties, corrosion resistance and biocompatibility (Geetha et al., 2009). Pure Ti w...

The fatigue strength, effects of a notch on the fatigue strength, and fatigue crack growth rate of Ti-15Zr-4Nb-4Ta alloy were compared with those of other implantable metals. Zr, Nb, and Ta are important alloying elements for Ti alloys for attaining superior long-term corrosion resistance and biocompatibility. The highly biocompatible Ti-15Zr-4Nb-4Ta alloy exhibited an excellent balance between...

ITO/Pb(Zr,Ti)O(3) contacts and Ag nanoparticles were used to construct a novel ferroelectric film photocathode exhibiting a stable short-circuit photocurrent of 110 μA cm(-2) and an open-circuit voltage of 0.76 V under 100 mW cm(-2) Xe-lamp illumination and zero-bias versus SCE.

The effective interatomic pair potentials for Ti, Zr, Hf, V, Nb, Ta and their hydrides are obtained by inverting the ab initio cohesive energy curves based on the lattice inversion method, and then the inverted pair potentials are used to calculate the mechanical and thermal properties of these hydrides.  2002 Published by Elsevier Science B.V.

The bond strength by three point bending strength of two metal substrates (commercially pure titanium or grade II, and Ti-6Al-4V alloy or grade V) combined to three distinct low-fusing ceramic systems (LFC) and the nature of porcelain-metal fracture by scanning electron microscopy (SEM) were evaluated. The results were compared to a combination of palladium-silver (Pd-Ag) alloy and conventional...
