The petroleum compounds were photocatalytically remediated from water using graphene (G)titanium oxide (TiO2) nanocomposite material in visible light radiation. The G-TiO2 nanocomposite was synthesized using sol-gel technique, and its structural & morphological properties were studied using scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), part...

Microfibrous palygorskite and tubular halloysite clay mineral combined with nanocrystalline TiO2 are incorporating in the preparation of nanocomposite films on glass substrates via sol-gel route at 450C. The synthesis is employing nonionic surfactant molecule as pore directing agent along with acetic acid-based sol-gel route without addition of water molecules. Drying and thermal treatment of c...

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...

BACKGROUND Iron oxide nanoparticles are of considerable interest because of their use in magnetic recording tape, ferrofluid, magnetic resonance imaging, drug delivery, and treatment of cancer. The specific morphology of nanoparticles confers an ability to load, carry, and release different types of drugs. METHODS AND RESULTS We synthesized superparamagnetic nanoparticles containing pure iron...

We fabricated plasmonic gold nanoparticle (AuNP)-TiO2 nanocomposite films and measured the photocurrent that originates from the water-splitting reaction catalyzed by the AuNP-TiO2 nanocomposite photoelectrocatalytic (PEC) electrode. The localized surface plasmon resonance (LSPR) of the gold nanoparticles affected the generation of photocurrent by TiO2 upon illumination with visible light. Elec...

در این تحقیق کامپوزیت Fe3O4/SiO2/TiO2با ساختار هسته- پوسته-پوسته با استفاده از روش شیمیایی تر تهیه شد. ابتدا کامپوزیت Fe3O4/SiO2 با استفاده از پیش ماده تترا اتیل اورتوسیلیکات (TEOS) سنتز شد. سپس یک پوسته از TiO2 به طور مستقیم بر روی آن پوشش داده شد. نانوساختارهای Fe3O4 / SiO2 / TiO2 تهیه شده با استفاده از آنالیزهای میکروسکوپ الکترونی روبشی محیطی (FESEM)، میکروسکوپ الکترونی عبوری (TEM)، الگوی پر...

A silver nanoparticle-decorated N,S-co-doped TiO2 nanocomposite was successfully prepared and used as an efficient photoanode in high-performance dye-sensitized solar cells (DSSCs) with N719 dye. The DSSCs assembled with the N,S-TiO2@Ag-modified photoanode demonstrated an enhanced solar-to-electrical energy conversion efficiency of 8.22%, which was better than that of a DSSC photoanode composed...

Background and Objectives: The green nanoparticle synthesis method using plants due to a cost effec�tive and environmental compatibility has been extensively noticed. In this study, the biosynthesis of Ag/Fe3O4 nanocomposite by using extract of Eryngium caucasicum and its antifungal properties has been reported. Methods: Synthesized Ag/Fe3O4 nanocomposite was characterized by using UV-Visible s...

The poly-o-phenylenediamine (PoPD)/TiO2 nanocomposite was successfully synthesized via 'in situ' oxidative polymerization method. The modified photocatalysts were characterized by BET, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier-transform infrarad spectra (FT-IR), thermogravimrtic analysis (TGA), X-ray photoelectron spectroscopy (...
