Titania films have been grown on polycrystalline BaTiO3 (BTO) substrates at 7001C by pulsed laser deposition. Electron backscatter diffraction (EBSD) was used to determine grain orientations in the substrate before growth, and the phase and orientation of the supported films after growth. All BaTiO3 grains within 261 of (001) were covered by anatase films with an orientation relationship of (00...

In this work, the development of a new crystallization technique is reported, using nitrogen plasma (AC) to obtain nanostructured anatase and rutile from amorphous titanium oxide (TiO2). This methodology increases throughput and minimizes thermal effects. Nanostructured amorphous TiO2 was obtained by the sol-gel method and subsequently subjected to AC treatment, at a controlled pressure, applyi...

Titania and doped-titania coatings can be deposited by a wide range of techniques; this paper will concentrate on magnetron sputtering techniques, including "conventional" reactive co-sputtering from multiple metal targets and the recently introduced high power impulse magnetron sputtering (HiPIMS). The latter has been shown to deliver a relatively low thermal flux to the substrate, whilst stil...

Dependent on the application or characterization method catalysts are exposed to different gas pressures, which results in structures. The quantitative determination of structure and composition a catalyst as function its environment allows establishment structure–performance relationships. Herein, we determine platinum–titania under hydrogen during temperature-programmed reduction over 3 order...

AIM The aim of this study was to determine the antifungal activity of titanium dioxide activated by indoor light on Czapek Yeast Agar (CYA). METHODS The agar plate method was used and titania P25 (Evonik) was added to the medium in the amount of 20 g.dm(-3). The control experiments without titania were also carried out. The water activity (a(w)) of the basal media was adjusted to 0.999, 0.997...

For detection of phenolic compounds a simple amperometric biosensor based on tyrosinase immobilized in titania sol-gel/Nafion composite was employed. Titania sol-gel was mixed with Nafion (v/v) in ratios 1:1 (TiO2/NF-1/1) and 2:1 (TiO2/NF-2/1), v/v. Morphology of immobilization composites was characterized by scanning electron microscopy. Analytical performance of biosensors with Nafion and bas...

Much work is needed in the design of more effective bone tissue engineering materials to induce the growth of normal bone tissue. Nanotechnology offers exciting alternatives to traditional bone implants since bone itself is a nanostructured material composed of nanofibered hydroxyapatite welldispersed in a mostly collagen matrix. For this purpose, poly-lactic-co-glycolic acid (PLGA) was dissolv...

Introduction Remediation of environment polluted with toxic chemical warfare agents (CWA) is a challenging task for authorities who deal with public health and environmental safety. Abnormal health symptoms appear when the human beings are exposed to these hazardous chemicals. Decontamination of surface or environment tainted with these toxic chemicals is the main job we have to do, to avoid he...

Titanium oxide nanoparticles were synthesized via a solvothermal treatment of titanium isopropoxide in the presence of L-lysine (lysine). The prepared nanostructures characterized by atomic force microscopy (AFM), X-ray diffraction (XRD), thermogravimetric analysis (TGA), diffraction scanning calorimetry (DSC), scanning electronic microscopy (SEM), transmission electron microscopy (TEM) and...
