BACKGROUND Mono aromatic hydrocarbons (BTEX) are a group of hazardous pollutants which originate from sources such as refineries, gas, and oil extraction fields, petrochemicals and paint and glue industries.Conventional methods, including incineration, condensation, adsorption and absorption have been used for removal of VOCs. None of these methods is economical for removal of pollutants of pol...

using titanium dioxide nano-silver packaging, which is antibacterial and resistance to the diffusion of gases such as oxygen, is increasing in food industry. therefore, we compared the effect of titanium dioxide-based nano-silver packaging and conventional polyethylene packaging on the fungal flora of consuming bread in order to increase the shelf-life storage of consuming bread. one hundred fo...

In this dataset we integrated figures related to bacterial transformation using pBI121 plasmid and complementary analysis for magnetic nanoparticles (MNPs) characterizations. The structural map of pBI121 plasmid was drawn by Vector NTI software using the complete sequence of binary vector pBI121. Escherichia coli bacteria transformed using pBI121 plasmid and were grown on the selection media co...

Electrocatalytic materials for oxygen reduction reaction, currently dominated by platinum/carbon catalyst is marred by drawbacks such as use of copious amount of Pt and use of "non-green" sacrificial reducing agent (SRA) during its synthesis. A single stroke remedy for these two problems has been achieved through an in-situ aqueous photoreduction void of even trace amounts of SRA with an enhanc...

In the photoelectrode, the important factor to achieve high efficiency of DSSC is weak acid treatment rather than specific regime of heat treatment. Acid treated paste of titanium oxide nano particles enhanced a factor of three higher of the energy conversion efficiency(none (η=2.0%), H2SO4(η=1.7%), HCl(η=2.8%), CH3COOH(η=6.2%) in dye-sensitized solar cells (DSSCs). The effects of the different...

Quantum dot (QD) sensitized solar cells based on Hierarchical TiO2 structure (HTS) consisting of spherical nano-urchins on transparent conductive fluorine doped tin oxide glass substrate is fabricated. The hierarchical TiO2 structure consisting of spherical nano-urchins on transparent conductive fluorine doped tin oxide glass substrate synthesized by hydrothermal route. The CdS quantum dots wer...

Anatase phase containing nano-crystallite TiO2 thin film is prepared by the peptization of modified Ti-isopropoxide sol using HNO3 as peptizing agent. The resulting sol is concentrated in a rotary evaporator bath. TiO2 film is deposited on ITO substrate by spin coating process. The compact film is annealed at 450 ̊C and 500 ̊C for optical studies. The subsequently it is modified as photo-anodes i...

Nickel doped TiO2nano particles (1% w/w) were prepared and immobilized on NaX zeolite and after characterization by X-ray diffraction and scanning electron microscopy used as photo catalyts for degradation of orange G. The X-ray diffraction patterns show that the supported TiO2 are crystallized in anatase form and the intensity of the zeolite peaks decreases with the incre...

ticl4, ammonia, inorganic salts as raw material, nanometer composite-crystal tio2 powders were synthesized by two-step chemical method. precursors were crystallized with different phase and stable composite-crystal tio2 with anatase and rutile phase was prepared at low temperature. quantitative control of crystal phase was realized. remarkable factors including reaction ph value, reaction time,...

A homemade N doped-TiO2 nanoparticle were used to degrade dibenzothiophene (DBT) in a model fuel flowing on bench-scale glass-made falling film reactor irradiated by xenon lamp that emitted visible light. The photocatalyst was immobilized the glass sheet. EDS, SEM, and FT-IR techniques utilized identify morphology of nanoparticles. Different operating parameters (e.g., loading (0, 4, 5, 6 wt%),...
