Selenium (Se) is an essential micro-nutrient for living organisms, but elevated concentrations in water can adversely affect health. In this research, we investigate the removal of selenium oxyanions (selenate and selenite) aqueous systems by integration adsorption on modified zeolites microbial reduction. Dynamic sorption-reduction experiments were conducted using two sets zeolite columns sele...

Combinations of TiO2 photocatalysts and various adsorbents have been widely studied for the adsorption and photocatalytic decomposition of gaseous pollutants such as volatile organic compounds (VOCs). Herein, a TiO2-zeolite-porous glass composite was prepared using melt-quenching and partial sintering, hydrothermal treatment, and drop coating for preparation of the porous glass support and X-ze...

Biomedical applications of superparamagnetic iron oxide nanoparticles (SPIONs) requiring precise control over their physical and magnetic properties, and proper surface treatment. Here we report a practical and effective electrochemical strategy for preparation of the polymer coated SPIONs. In this strategy, in situ polymer coating on the surface of SPIONs was achieved through electrodeposition...

TiO2 is a very well-known and well-researched material due to the stability of its chemical structure, biocompatibility, and its physical, optical and electrical properties. In this study, the synergistic effect of nano-TiO2 immobilized on activated carbon, zeolite Y and ZSM-5 on the removal of styrene vapors from polluted air was investigated. The prepared catalysts were characterized by SEM, ...

The use of doses higher than 500 g of Zeolite leads to a dramatic depression of feed intake. Even the effective dose reduces feed intake and induces hypophosphataemia; however, these effects are considered transient. Zeolite may reduce serum Mg but this is without physiological significance. Serum levels of copper and zinc as well as milk yield and composition are not affected by Zeolite treatm...

The Stober process is frequently used to prepare silica-coated iron oxide nanoparticles. This is usually achieved by seeding a reaction mixture consisting of water, ethanol and a catalyst with iron oxide particles and adding a silica precursor. The hydrolysis and condensation of precursor monomers results in the deposition of a silica layer on iron oxide particles. However, this process is acco...

Magnetic nanoparticles are frequently coated with SiO2 to improve their functionality and bio-compatibility in a range of biomedical and polymer nanocomposite applications. In this paper, a scalable flame aerosol technology is used to produce highly dispersible, superparamagnetic iron oxide nanoparticles hermetically coated with silica to retain full magnetization performance. Iron oxide partic...

PURPOSE To compare the cellular uptake efficiency and cytotoxicity of aminosilane (SiO(2)-NH(2))-coated superparamagnetic iron oxide (SPIO@SiO(2)-NH(2)) nanoparticles with three other types of SPIO nanoparticles coated with SiO(2) (SPIO@SiO(2)), dextran (SPIO@dextran), or bare SPIO in mammalian cell lines. MATERIALS AND METHODS Four types of monodispersed SPIO nanoparticles with a SPIO core s...
