objective: surface coating of dental mirrors using nanotechnology has been done to render them self-cleaning properties. nano-scaled titanium dioxide particles (tio2)show antimicrobial properties when exposed to ultra-violet (uv) light. the aim of this study was to evaluate the effect of surface coating of dental mirrors with nano titanium dioxide on their self-cleaning (from dentists’ perspect...

objective(s): titanium dioxide (tio2) nanoparticles (nps) are widely used in commercial food additives and cosmetics worldwide. uptake of these nanoparticulate into humans by different routes and may exhibit potential side effects, lags behind the rapid development of nanotechnology. thus, the present study designed to evaluate the toxic effect of mixed rutile and anatase tio2 nps on serum bioc...

the present experimental study reports on enhancement of heat transfer by addition of nanoparticles to the working fluid of commercial swimming pool heat exchangers under laminar flow condition. three different concentrations of titanium dioxide nanoparticles were added to the water as working fluid of a typical forced convective heat exchanger used to transfer heat to public swimming pools. th...

Mesophase ordering and structuring are carried out to attain optimized pore morphology, high crystallinity, stable porous framework, and crack-free mesoporous titanium dioxide (TiO(2)) films. The pore structure (quasi-hexagonal and lamellar) can be controlled via the concentration of copolymer, resulting in two different types of micellar packing. The calcination temperature is also controlled ...

The Effect of Different Levels Titanium Dioxide Nanoparticles in Soil on Sorghum Growth Characteristics

Effect of Methanol and Titanium Dioxide Nanoparticles on Phytochemical Properties Artichoke (Cynara scolymus L.)

Details of coupling a catalytic reaction chamber to a liquid nitrogen-cooled cryofocuser/triple quadrupole mass spectrometer for online monitoring of nitric oxide (NO) photocatalytic reaction products are presented. Cryogenic trapping of catalytic reaction products, via cryofocusing prior to mass spectrometry analysis, allows unambiguous characterization of nitrous oxide (N2O) and nitrogen oxid...

The nanoparticle industry is expected to become a trillion dollar business in the near future. Therefore, the unintentional introduction of nanoparticles into the environment is increasingly likely. However, currently applied risk-assessment practices require further adaptation to accommodate the intrinsic nature of engineered nanoparticles. Combining a chronic flow-through exposure system with...
