in this study, nano-tio2 was employed for the adsorption of chloroform from aqueous solution in batch equilibrium experiments to investigate its adsorption properties. the effects of ph, initial chloroform concentration and nano-tio2 dosage were also investigated. optimal conditions for chloroform removal by nano-tio2 have been then identified. results of equilibrium experiments showed that the...

Nano-TiO2 is widely used as a commercial food contact material (FCM), which poses potential risks to food. Therefore, the migration of TiO2 crucial for safety FCM. Since PET/TiO2 composite films are layers producing polymer-laminated steel cans and majority beverages contained in acidic, it necessary study from acidic solutions. The 4% (v/v) acetic acid was studied through ICP-OES method. corro...

This study describes the application of novel chemistry methods for the removal of dye by Nano structured titanium oxide (TiO2) photo catalysts. Such materials can be applied in the development of efficient photo catalytic systems for the treatment of water. Nano crystalline TiO2 was synthesized by Sol-Gel route using titanium tetraisopropoxide as a metal precursor. The catalysts were character...

A novel photoanode architecture with plasmonic silver (Ag) nanostructures embedded in titania (TiO2), which served as the wide band gap semiconducting support and CdS quantum dots (QDs), as light absorbers, is presented. Ag nanostructures were prepared by a polyol method and are comprised of clumps of nanorods, 15-35 nm wide, interspersed with globular nanoparticles and they were characterized ...

in this research between 3-dimensional and axisymmetric modeling for movement of nano-particles in passing through a aerodynamic lens, and also between these models and famous model of wang & liu was compared. for this purpose, output of nano-particles penetration, divergence angel, and nano-particle velocity with wang & liu model was compared. geometrical model used for aerodynamic lens compar...

Nanoporous Pt/TiO2 micro-particles were synthesized via an aerosol assisted co-assembly (AACA) route. Aerosol droplets were produced from a colloidal mixture of 5 nm Pt and 20 nm TiO2 nanoparticles, which formed spherical micro-aggregates of Pt and TiO2 with average diameter of around 1.2 μm. The resulting composite micro-particles have very open structure with pore sizes ranging from 20 to 200...

background sulfur oxides released from the burning of oil causes severe environmental pollution. the sulfur can be removed via the 4s pathway in biodesulfurization (bds). immobilization approaches have been developed to prevent cell contamination of oil during the bds process. objectives the encapsulation of rhodococcus erythropolis r1 in calcium alginate beads was studied in order to enhance c...

in the current paper, finite element method is employed for numerical simulations and the study of influential parameters on elastic modulus of polymer-matrix nano-composites. effects of different key parameters including particle elastic modulus, interphase elastic modulus, matrix elastic modulus, interphase thickness and particle volume fraction on total elastic modulus of nano-composite mate...
