In  this  reaserch,  photocatalyst  titanium  dioxide  was  doped  with silver  and modified  by  polyethylene  glycol  by  sol  gel method  and the  samples  were  characterized  by  X-ray  diffraction  (XRD)  and scanning  electron  microscopy  (SEM).  The  purpose  of  the  present study  was  to  evaluate  the  photocatalytic  bactericidal  effects  of prepared nanocomposite on human p...

T itanium dioxide (TiO 2) is a multi-faceted compound. It's the stuff that makes toothpaste white and paint opaque. TiO 2 is also a potent photocatalyst that can break down almost any organic compound, and a number of companies are seeking to capitalize on TiO 2 's reactivity by developing a wide range of environmentally beneficial products. During the late 1970s, scientists began to realize th...

Titanium dioxide (TiO(2)) microspheres synthesized by sol-gel method showed high affinity to glycopeptides and were successfully used for simultaneous enrichment of glycopeptides and phosphopeptides.

In this paper, titanium dioxide nano-particles were synthesized by sol-gel method in acidic atmosphere. The microstructure, morphology, optical band gap, and hydrophilicity of the sample were studied. Optical band gap of titanium dioxide was probed via Diffuse Reflectance Spectra (DRS) and contact angle (CA) was measured to investigate surface activity. XRD analysis was used to study crys...

Iron-doped titanium dioxide nanoarchitectures with ordered mesopore periodicity and enhanced photocatalytic activity have been developed as photofunctional materials for environmental purification.

Could titanium-clean air be how advertisers one day try to sell us the virtues of paint or even clothing that reduces the pollution caused by automobiles? The technology behind such products involves the well-known ability of titanium dioxide (TiO2) to photocatalytically split water to form hydroxyl and peroxyl radicals, a reaction that has already been harnessed to make self-cleaning windows. ...

For example, if Coating A has a contrast ratio of 0.920 and Coating B has a contrast ratio of 0.900, about all that can be said is Coating A has higher opacity than Coating B. We can say it is 0.020 higher, but it is not clear how to use this number to formulate Coating B to have equal hiding. Also, this is not helpful in deciding what to change in order to improve opacity. Fortunately, quantit...
