Titanium oxide (TiO2 , titania) is well-known as an important ceramic material. Due to its versatile optical, electrical and photochemical properties, it has found extensive applications in high-refractive index devices, optical waveguides, photo-catalysts and photovoltaic cells. Particularly, in the form of very fine particles on the scale of ten to hundreds of nanometers, TiO2 , along with ot...

Nitrogen-doped titania nanosheets with visible light response were synthesized by exfoliating a layered titanate with homogeneous nitrogen doping.

Thermally stable mesoporous core-shell structured titania microspheres with well-defined hollow interiors were directly prepared by a novel hydrothermal precipitation of TiCl4 in the presence of urea and ammonium sulfate.

A column-switching high-performance liquid chromatography (HPLC) system for the determination of phosphopeptides has been developed. The method is based on the selective adsorption of phosphopeptides on a titania (TiO2) precolumn and successive HPLC separation of the phosphopeptides on an anion-exchange column with a UV detector (215 nm). The recoveries of phosphopeptides were tested using auth...

The adsorption of CO on polycrystalline TiO2 was investigated by static adsorption microcalorimetry. The initial differential heat of adsorption (qdiff,0) of CO on polycrystalline titania is 40 kJ/mol, and the standard adsorption entropy (Deltas0) is -104 J mol(-1) K(-1). These results are consistent with those derived from temperature-programmed desorption and FTIR results in the literature. T...

Metal oxide nanotubes have become a widely investigated material, more specifically, self-organized titania nanotube arrays synthesized by electrochemical anodization. As a highly investigated material with a wide gamut of applications, the majority of published literature focuses on the solar-based applications of this material. The scope of this review summarizes some of the recent advances m...

A new generation of bone cement with mechanical properties significantly higher than that of commercially available acrylic bone cements are strongly desired in order to ensure the long term clinical performance of the cemented arthroplasty. Currently commercial acrylic bone cement formulations contain micron-sized particles of either BaSO4 or ZrO2 to provide radiopacity, however these particle...

Over the past decades it has become clear that supported gold nanoparticles are surprisingly active and selective catalysts for several green oxidation reactions of oxygen-containing hydrocarbons using molecular oxygen as the stoichiometric oxidant. We here report that bifunctional gold–titania catalysts can be employed to facilitate the oxidation of amines into amides with high selectivity. Fu...

Ultraviolet–Visible (UV–Vis) spectroscopy was used, in the current investigation, to explore the dispersion and stability of titania nanoparticles in an aqueous media with different types of dispersants. Hydrochloric and nitric acids as well as ammonia were used to determine the stability of the suspension in the acidic region (pH=2.5) and basic area (pH=9.5), respectively. In addition, for mea...
