Nanoscale titanium dioxide is an important physical sun-block material and is widely used in sunscreen. In our test, the influences of the particle size and crystal structure on light absorbance were examined. The experiment shows that the absorbance (Abs) of nanoscale titanium dioxide in UV-ray district is much higher than it in visible light district under the same concentration (0.04 g/L). T...

Dentistry and orthopedics are undergoing a revolution in order to provide more reliable, comfortable and long-lasting implants to patients. Titanium (Ti) and titanium alloys have been used in dental implants and total hip arthroplasty due to their excellent biocompatibility. However, Ti-based implants in human body suffer surface degradation (corrosion and wear) resulting in the release of meta...

Nanoparticles are atomic or molecular particles with at least 1–100 nanometer diameters. They have entered vastly into the world of agriculture and biology; this is because of their special effect and their unique features. Their unknown impact on living things and the ecosystems has caused a lot of concern. This research was done in order to study the effects of nano-TiO2 and nano aluminium on...

This research demonstrates a simple method for synthesizing titanium dioxide nanoparticle-decorated carbon nanofibers. These nanofibers showed highly efficient degradation of methylene blue under UV light because of the synergistic effects of the large surface-active sites of titanium dioxide nanoparticles and the carbon nanofibers on the photocatalytic properties.

wastewater from molasses processing contains a large amount of coloured substances that give a recalcitrant dark brown colour and high organic load to the effluent. photocatalytic decolourization of molasses wastewater was performed using titanium dioxide catalyst coated on the surface of south african natural zeolite using the solid-solid dispersion method. addition of hydrogen peroxide as an ...

Titanium dioxide and copper oxide nanoparticles are more and more widely used because of their catalytic properties, of their light absorbing properties (titanium dioxide) or of their biocidal properties (copper oxide), increasing the risk of adverse health effects. In this frame, the responses of mouse macrophages were studied. Both proteomic and targeted analyses were performed to investigate...

adsorption of no2 molecule on pristine and n-doped tio2 anatase nanoparticles have been studied using the density functional theory (dft) technique. the structural properties (such as bond lengths and bond angles) and the electronic properties (such as density of states, band structures and atomic partial charges) have been computed for considered nanoparticles. the results show that, the adsor...

This paper presents the improvement of the antimicrobial character of woven fabrics based on cotton. The woven fabrics were cleaned in oxygen plasma and treated by padding with silver chloride and titanium dioxide particles. The existence of silver and titanium on woven fabrics was evidenced by electronic microscope images (SEM, EDAX) and by flame atomic absorption spectrophotometry. The antimi...

The Journal of Physical Chemistry is published by the American Chemical Society. 1155 Sixteenth Street N.W., Washington, DC 20036 Photoinduced oxidation of bromide to bromine on irradiated platinized titanium dioxide powders and platinized titanium dioxide particles supported on Nafion films Reza Dabestani, Xuelin Wang, Allen J. Bard, Alan Campion, Marye Anne Fox, Stephen E. Webber, and J. M. W...

413 Indian Journal of Dermatology 2014; 59(4) the patient may have taken, or due to the coloring agent titanium dioxide present in the tablet of levocetirizine. However, detailed history taking excluded possibility of both, as there was no other drug intake during last 4 weeks. Also, the patient did not develop any reaction on provocation with fexofenadine, which contained titanium dioxide. The...
