Facile synthesis of smartaminosilane modified- SnO/porous silica nanocomposite for high efficiency removal of lead ions and bacterial inactivation.

The aim of the present study is to synthesize a new and proficient nanoadsorbent for rapid removal of heavy metals and disinfection of microorganisms. The proposed nanoadsorbent was fabricated using SnO nanoparticles as the core, coated with mesoporous silica and further modified with 3-Aminopropyl triethoxysilane to render SnO/PSi/NH nanocomposite. The nanocomposite was characterized using Fourier Transform Infrared (FTIR), X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Nitrogen adsorption-desorption analysis.

The application of response surface methodology on the synthesis of conductive polyaniline/cellulosic fiber nanocomposites.

The chemical oxidation polymerization was used in situ aimed at preparing polyaniline/cellulosic fiber nanocomposites that are highly intrinsic and conductive in nature. The prepared composites were characterized by Fourier transform infrared (FTIR) thermal Gravimetric analysis (TGA), and their morphology was investigated using field emission scanning electron microscope (FE-SEM) to elucidate the mechanism of conductivity decay of the paper nanocomposite. Box-Behnken experimental design method was applied to determine the optimum synthesis parameters.

Experimental design data for the zinc ions adsorption based on mesoporous modified chitosan using central composite design method.

In the present study, new generation of silica-based mesoporous adsorbents were introduced for the removal of heavy metals with the aim of developing new adsorption technologies in water treatment. The magnetic nanoadsorbent, prepared by modification of SBA-15 with [3-(2-Aminoethylamino) propyl] trimethoxysilane (AEAPTMS)-functionalized chitosan, was applied for the removal of Zn from aqueous solution. The synthesized FeO@SBA-15-CS-AEAPTMS nanoadsorbent was thoroughly characterized using XRD, TEM, FTIR and BET analysis.

Synthesis of a smart pH-responsive magnetic nanocomposite as high loading carrier of pharmaceutical agents.

To create facile external controlled drug delivery system, a magnetic porous carrier based on Tin oxide nanoparticles was synthesized by an inexpensive and versatile hydrothermal strategy and used for in-vitro process. Magnetic nanocomposites were qualified by Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Vibrational Sample Magnetometer (VSM) and Transmission Electron Microscopy (TEM). Results showed that nanoparticles were synthesized successfully with good dispersion of magnetic nanoparticles in cavity, uniform particle size distribution with average size of 65nm and high magnetization of 33.

Thermal stability enhancement of modified carboxymethyl cellulose films using SnO2 nanoparticles.

In this study, in-situ and ex-situ hydrothermal synthesis procedures were applied to synthesize novel CMC/porous SnO2 nanocomposites from rice husk extracted carboxymethyl cellulose (CMC) biopolymer. In addition, the effects of SnO2 nanoparticles on thermal stability of the prepared nanocomposite were specifically studied. Products were investigated in terms of morphology, particle size, chemical structure, crystallinity and thermal stability by using field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermogravimetric analysis (TGA), respectively.
