In this study, in order to achieve effective coating of the homogeneous titanium dioxide (TiO2) thin film, UV irradiation pre-treatment was carried out to activate PC surfaces before coating. Sol-gel-based nanocrystalline TiO2 thin films were prepared by employing tetrabutyl-titanate as a precursor. Nanocrystalline TiO2 thin films were deposited by sol-gel spin coating on the treated substrates...

Tungsten and titanium oxide (WO3/Ti) nanowires (NWs) were grown by thermal oxidation of a tungsten and titanium alloy (WTi) metallic layer deposited on 2 × 2 mm2 alumina substrates by DC magnetron sputtering. Thermal oxidation was carried out in a custom evaporator chamber. Several parameters were controlled to achieve the optimal growth conditions. Morphological and structural analysis were pe...

Researchers are testing different treatments to induce modifications in both chemical composition and topography of implant surface, with the aim to ameliorate bone-to-implant contacts and hence improve osseointegration processes and biomechanical properties in the short and long-term. Aim of the present research was the evaluation of MG63 osteoblast-like cells behaviour on polymeric coatings, ...

A comparative study of two coating methods on titanium (Ti) substrates, sol-gel and electrophoresis processes, was performed. Before coating, two different surface treatments were employed. The hydroxyapatite (HA) powder were characterized by infrared spectroscopy (FTIR) and X-ray diffraction (XRD) while coated samples were examined by using scanning electron microscopy (SEM) with energy disper...

The oxidation of titanium substrates in the air under laser irradiation is investigated. experimental dependence TiO2 layer thickness on number pulses subjected to comprehensive analysis. prevailing chemical and physical processes substrate surface near-surface are determined. It found that drives surface-energy induced mixing substrates. rate sharply depends temperature. This allowed detect ex...

We have investigated the surface bioactivity of titanium after water and hydrogen plasma immersion ion implantation. Plasma immersion ion implantation (PIII) excels in the surface treatment of components possessing a complicated shape such as medical implants. In addition, water and hydrogen PIII has been extensively studied as a method to fabricate silicon-on-insulator (SOI) substrates in the ...

This paper reports the fabrication of a bulk micromachined hybrid torsional micromirror device composed of titanium mirror structures bonded to an underlying silicon sloping electrode structure. The fabrication of the device is enabled by two recent innovations: 1) the Metal Anisotropic Reactive Ion etching with Oxidation (MARIO) Process [1], which provides, for the first time, high aspect rati...
