Research ArticleOpen accessIn the abstractSYNTHESIS AND CHARACTERIZATIONOF ORGANIC FUNCTIONALIZED MESOPOROUS SILICA AND EVALUATE THEIR ADSORPTIVE BEHAVIOR FOR REMOVAL OF METHYLENE BLUE FROM AQUEOUS SOLUTIONSameer H. Kareem, Inaam H. Ali, M. G. JalhoomThree Mesoporous Silica (MPS) with different functional groups were prepared by one-step synthesis based on the simultaneous hydrolysis and condensation of tetraethoxy silane with organo-silane in the presence of template surfactant Polydimethylsiloxane-Polyethyleneoxide (PDMS-PEO). The prepared materials were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA) and nitrogen adsorption-desorption experiments. The results indicate that the preparation of methyl and … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 28 Feb 2014 · 7,287 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Gold Nanoparticles by TryptophaneAzim Akbarzadeh, Davood Zare, Ali Farhangi et al.Problem statement: Preparation and synthesis of gold nanoparticles with small size and suitable stability is very important and applicable particularly in medicine. In this study, we have prepared gold nanoparticles by chemical reduction method employing L-Tryptophane as a reducing agent for ionic gold. Approach: The gold nanoparticles are the most employed amongst the different metallic nanoparticles in the fields of … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 10,046 accessesView PDFCite
