Commercially pure titanium for bone-anchored dental implants, submitted to a sand-blasting and acid-etching (SLA) surface treatment, has been mechanically tested and analyzed by SEM and TEM observations. A face-centered cubic titanium hydride layer grows on the polycrystalline titanium substrate with various epitaxial relationships, whose grains show also epitaxial relationships with each other...

Films combining hydroxyapatite (HA) with minute amounts (ca. 1 weight %) of (rhenium doped) fullerene-like MoS₂ (IF) nanoparticles were deposited onto porous titanium substrate through electrophoretic process (EPD). The films were analyzed by scanning electron microscopy (SEM), X-ray diffraction and Raman spectroscopy. The SEM analysis showed relatively uniform coatings of the HA + IF on the ti...

The titanium silicide thin films had been formed on Si substrate by reacting of TiX4 (X=Cl, Br) with Si under different experimental conditions. The Si consumption and the titanium silicide obtains were calculated by the film thickness. In some reactions, titanium silicide thin film was found not only on the Si substrates but also on the SiO2 wall at the outlet of the reaction chamber. The quan...

OBJECTIVES Anodized treated titanium surfaces, have been proposed as potential surfaces with better cell attachment capacities. We have investigated the adhesion and proliferation properties of H9C2 cardiac myoblasts on anodized treated titanium surface. MATERIALS AND METHODS Surface topography and anodized tubules were examined by high-resolution scanning electron microscopy (SEM). Control a...

We study the Casimir force between a nanoparticle and a substrate. We consider the interaction of metal nanoparticles with different substrates within the dipolar approximation. We study the force as a function of the distance for gold and potassium spheres, which are over a substrate of titanium dioxide, sapphire and a perfect conductor. We show that Casimir force is important in systems at th...

A fundamental study on the effect that pre-coating a substrate with metal spraying has on the properties of sputtered Titanium-nitride film (TiN film) was carried out. The residual stresses in TiN films sputtered on the substrates coated with various spray coatings were measured by X-ray stress measurement. It was observed that the residual stresses in TiN films sputtered on substrates coated b...

Germanium nanowires have been grown successfully on titanium. The wires are single crystal, with some low angle stacking faults and other defects. Growth of nanowires on metal substrates offers reduced cost over single crystal substrates, while still offering an electrical contact to the wire core for core-shell junction structures. Summary of Research: Figure 1: 80 nm germanium nanowires on a ...
