Inkjet printing technique is proposed for the fabrication of titanium dioxide (TiO2) photoanodes with a synthetic colloidal TiO2 ink. The resultant electrodes were characterised usingmaterials characterisation methods (such as scanning electronmicroscope, X-ray diffraction andUV–vis spectrophotometer) aswell as photoelectrochemical means. The preliminary results indicate that the nanostructure ...

We report a comparative study on the photodegradation of the widely used benzodiazepine psychoactive drug alprazolam (8-chloro-1-methyl-6-phenyl-4H-[1,2,4]triazolo[4,3-a][1,4]benzodiazepine, ALP) using direct photolysis, and titanium dioxide photocatalyzed reaction. Titanium dioxide photocatalysts were prepared as nanoparticles by acidic sol-gel methods, calcined at two different temperatures, ...

The photocatalytic oxidation of 4-methoxybenzyl alcohol to p-anisaldehyde (PAA) was performed in water with organic-free suspensions of home-prepared and commercial titanium dioxide (TiO2) catalysts. The nanostructured TiO2 samples were synthesised by boiling aqueous solutions of titanium tetrachloride (TiCl4), under mild conditions, for different times. The crystallinity increased with the boi...

Nanosized titanium dioxide (TiO2) in its anatase form is the most frequently studied and as well as used photocatalyst. There are several syntheses procedures which enable to achieve photocatalytic TiO2. The solgel method utilizing titanium alkoxides is used most often. Alternative precursors such as titanium tetrachloride and titanyl sulphate are also frequently employed. Nowadays the environm...

Titanium dioxide (TiO2) nanoparticles, with an average size of about 45 nm, were encapsulated by polystyrene using in situ nitroxide mediated radical polymerization   in the presence of 3-aminopropyl triethoxy silane (APTES) as a coupling agent and 2, 2, 6, 6-tetramethylpiperidinyl-1-oxy  as a initiator. First, the initiator for NMRP was covalently bonded onto the surface of Titanium dioxide na...

The aim of this study was to prepare a novel targeting drug delivery system for 2-Methoxyestradiol (2ME) in order to improve the clinical application of this antitumor drug. It is based in nanoparticles (NPs) of titanium dioxide (TiO2) coated with polyethylene glycol (PEG) and loaded with 2ME. A complete IR and Raman characterization have been made to confirm the formation of TiO2–PEG–2ME compo...

This paper presents titanium dioxide nanostructured surfaces prepared in organic electrolytes containing ammonium fluoride by anodic oxidation method. Two approaches were used for fabrication, one-step and two-step anodization. The obtained TiO2 surfaces have nanoporous structure. The morphology of anodized TiO2 nanostructures was characterized by scanning electron microscopy (SEM).

Titanium dioxide (TiO2) is one of the most widely studied photocatalysts during the past decades due to its ability to photo-oxidize harmful chemicals in both air and water to CO2 in the presence of UV light. TiO2 also shows promise for energy applications such as water splitting [1], as well as in photochemical solar cells [2]. TiO2 use has also been extended to large scale commercial producti...

Background Titanium dioxide (TiO2) nanoparticels (NPs), one of the most abundantly utilized nanomaterials, was widely used in industry, cosmetics, and biomedicine. There have been reported that TiO2 NPs aggravates respiratory symptoms by induce pulmonary inflammation. However, the mechanisms of these effects have not been extensively studied yet. We aimed to investigate inflammation in rabbit l...
