Photo-catalysts have many applications in different fields of industry especially in elimination of pollutants and heavy metals from wastewater. In this study first three component nano composite and two components nano composite were prepared. These composite were applied on non-woven textiles by Pad-dry method and their effect on elimination of color and heavy metals were investigated. Morpho...

Co-doped TiO2 nanoparticles containing 0.0085, 0.017, 0.0255, 0.034, and 0.085 mol % Co(III) ion dopant were synthesized via sol-gel and dip-coating techniques. The effects of metal ion doping on the transformation of anatase to the rutile phase have been investigated. Several analytical tools, such as X-ray diffraction (XRD), transmission electron microscope (TEM), X-ray photoelectron spectros...

In this study, Ba3SrNb2O9(s) was synthesized using conventional solid-state reaction route, characterized by powder XRD and SEM-EDAX. The standard molar enthalpy of formation determined measuring enthalpies solution in {PbO + B2O3} solvent (in 2:1 ratio) at T = 966 K an oxide melt high temperature calorimeter. increment measured with same heat capacity the also employing DSC. Based on smoothed ...

Thick film technique is popular because of low cost, simple for construction and better sensing surface area, hence for resistive gas sensor thick films of pure ZrO2 powder were prepared by Standard screen printing technique. The material was characterized by X-Ray diffraction pattern, surface morphology was observed by SEM, elemental composition were observed by EDAX and optical properties wer...

Iron(III) was loaded onto the sulphonic acid sites of Duolite C26, a commercial cation-exchanger, and was then converted into hydrated ferric oxides (HFO) disbursed throughout the macropores of the ion exchanger beads. The resulting hydrated iron(III)-oxide loaded cation exchange resin (HFOLR) was tested for its ability to remove arsenate [As(V)] ions present in water by batch technology. The s...

In this contribution, we report the synthesis of CdS nanoparticles directly conjugated to an enzyme, R-chymotrypsin (CHT) by chemical reduction in aqueous solution. Matrix-assisted laser desorption ionization (MALDI) mass spectrometry confirms the strong conjugation of CdS nanoparticles to CHT through covalent bonding in the CdS-CHT conjugates. High-resolution transmission electron microscopy (...
