  1. 21. Development and potential applications of nanomaterials for arsenic removal from contaminated groundwater.

    University essay from KTH/Miljögeokemi och ekoteknik

    Author : Rajender Kumar; [2011]
    Keywords : Iron oxide nanoparticles NPs ; surface modification; structural charcaterisation; Arsenic species;

    Abstract : In this study, a magnetic nanomaterial was used for the binding of anionic arsenic species from contaminated groundwater. Iron oxide (Fe3O4) magnetic nanoparticles (NPs) and the surface modified Fe3O4 NPs with 3-aminopropyl-triethoxysilane (3-APTES), Trisodium citrare (TSC) and Chitosan were synthesized with the co-precipitation method.

  3. 22. Experimental studies of nucleation and growth of nanoparticles using a pulsed hollow cathode discharge

    University essay from KTH/Rymd- och plasmafysik

    Author : Asparuh Stanev; [2011]
    Keywords : ;

    Abstract : The properties of the nanoparticles are highly eected by their size. In order to apply nanoparticles commercially it is desirable to synthesize them with a narrow size distribution and at high productivity. We synthesized copper nanoparticles (grains) using a plasma generated by a hollow cathode with a pulsed voltage. READ MORE

  4. 23. Synthesis and functionalization of Gd-based nanoparticles for MRI contrast enhancement

    University essay from Institutionen för fysik, kemi och biologi

    Author : Andreas Skallberg; [2011]
    Keywords : ;

    Abstract : Magnetic metal oxide nanoparticles for contrast enhancement in Magnetic Resonance Imaging (MRI) have proven to be one of the most promising applications in diagnostic science. The nanoparticles can provide better and more accurate diagnosis by their capability to enhance the contrast between different soft tissues. READ MORE
