The Effect of Water on Particle Size, porosity, and the Rate of Drug Release from Implanted Titania Resrvoirsia

Lopez T., Hernandez-Ayala A., Odriozola J.A., Quintana P., Gonzalez R.D., Lottici P.P., Marino I., Tulane University, US

In this study, sol-gel titania implants used in the controlled rate of drug release of valproic acid to the temporal lobe of the brain were optimized to insure that the correct drug dose is delivered. [...]

Photoactive titania and nanoparticulate silver-titania composite thin films as potent antimicrobial coatings

Page K., Parkin I.P., Wilson M., University College London, UK

Nanocrystalline titania (anatase) and Ag-doped titania (anatase) coatings were prepared on glass microscope slides by a sol-gel dip-coating method. The resultant coatings were characterised by X-ray diffraction, XANES, Raman, SEM/WDX, XPS and UV visible techniques [...]

Sensing of Organic Vapors by Flame-Made TiO2 Nanoparticles

Teleki A., Pratsinis S.E., Kalyanasundaram K., Gouma P.I., ETH Zürich, CH

Nanostructured anatase TiO2 was produced by flame spray pyrolysis (FSP) and tested for sensing of volatile organic compounds and CO at 500 °C. The as-prepared powders were characterized by transmission/scanning electron microscopy, x-ray diffraction and [...]

Nanostructured Surface Treatment Enables the Combination of Nano-particulate ZnO and TiO2 with Acrylate-based Polymers in Cosmetic Formulations

Andre V., Brotzman Jr. R.W., Nanophase Technologies, US

Modern skin care formulations must meet high standards of efficacy, skin compatibility and aesthetic appeal. The performance of a cosmetic product is related to the entire formulation and an optimal galenic formulation that incorporates a [...]
