In this research we have developed a treatment method for textile wastewater by TiO2/SiO2-based magnetic nanocomposite. Textile wastewater includes a large variety of dyes and chemicals and needs treatments. This manuscript presents a facile method for removing dyes from the textile wastewater by using TiO2/SiO2-based nanocomposite (Fe3O<su...

Polythiophene/chitosan magnetic nanocomposite as an adsorbent of magnetic solid phase extraction was proposed for the isolation of fluoxetine in aqueous and biological samples prior to fluorescence detection at 246 nm. The synthesized nanoparticles, chitosan and polythiophene magnetic nanocomposite, were characterized by scanning electron microscopy, FT-IR, TGA, and EDAX. The separation of the ...

We herein report a novel and facile approach to the fabrication of the superparamagnetic magnetite/poly(styrene-co-12-acryloxy-9-octadecenoic acid) nanocomposite microspheres with controllable structure via gamma-ray radiation induced inverse emulsion polymerization under room temperature and at ambient pressure. 12-Acryloxy-9-octadecenoic acid (AOA, containing part of sodium salts Na-AOA) as a...

Objective(s): Relevance between magnetic resonance imaging (MRI) relaxation rate and concentration of magnetic nanoparticles determines the capability of a nanomaterial to provide MRI contrast. In the present study, alginate was conjugated to gadolinium/graphene oxide nanocomposite to form gadolinium/graphene oxide/alginate nanocomposite, aiming to investigate its effect on the relevance betwee...

We report the formation of lipid membranes supported by a soft polymeric cushion of polydopamine. First, 20 nm thick polydopamine films were formed on mica substrates. Atomic force microscopy imaging indicated that these films were also soft with a surface roughness of 2 nm under hydrated conditions. A zwitterionic phospholipid bilayer was then deposited on the polydopamine cushion by fusion of...

We report highly efficient magnetically recoverable photocatalysts through combination of Fe3O4/ZnO with AgI and Ag2CO3, as narrow band gap semiconductors. The resultant photocatalysts were characterized by XRD, EDX, SEM. TEM, UV–vis DRS, FT-IR, PL, and VSM instruments. Under visible-light illumination, the nanocomposite with 1:6 weight ratio of Fe3O4 to ZnO/AgI/Ag2CO3 exhibited superior activi...

We report an experimental study of the adhesion properties of polydopamine thin films and their bonding behavior on polymer, glass and metal surfaces. Dopamine is able to adsorb onto all surfaces and self-polymerize into a thin hydrophilic film. Dynamic contact angle measurements revealed a large contact angle hysteresis between advancing and receding angles and a possible hydration layer when ...
