Abstract
  This work is reported on the synthesis of Fe3O4/eggshell nanocomposites in the absence of any stabilizer or surfactant. Fe3O4 magnetic nanoparticles were established on the egg shell nano-composite. The nanocompositeshave shown high catalytic activities in the synthesis of Tetrahydrobenzo[b]pyran. ...  Read More

Abstract
  Magnetic silica nanoparticles modified by 3-[2-(2-aminoethylamino) ethylamino] propyl-trimethoxysilane (AAAPTS) and Salicylaldehyde were prepared and used as a new adsorbent for extraction and preconentration of copper ion through magnetic solid-phase extraction (MSPE) method. After adsorption, these ...  Read More
