  1. 1. Building crystals out of crystals : Synthesis, structure and magnetic properties of iron oxide nanoparticles and self-assembled mesocrystals

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Erik Wetterskog; Stockholms universitet.; [2013]
    Keywords : Natural Sciences Chemical Sciences Materials Chemistry; Naturvetenskap Kemi Materialkemi; iron oxide; nanoparticle; synthesis; self-assembly; characterization; electron microscopy; scattering; magnetic properties; materialkemi; Materials Chemistry;

    Abstract : This thesis is focused on the fabrication and characterization of self-assembled arrays of magnetic iron oxide (Fe3O4, γ-Fe2O3 and Fe1-xO) nanoparticles. The synthesis of spherical and cubic iron oxide nanocrystals, with sizes between 5 and 30 nm and narrow size distributions, is demonstrated, along with a rigorous morphological characterization of the cubic nanoparticles.

  2. 2. Heterogeneous Photolytic Synthesis of Nanoparticles

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Oscar Alm; Uppsala universitet.; [2007]
    Keywords : Chemistry; LCVD; Nanotechnology; Metallocene; Magnetic; Photolysis; OES; tungsten oxide; gas sensing; Kemi;

    Abstract : Nanoparticles of iron, cobalt and tungsten oxide were synthesised by photolytic laser assisted chemical vapour deposition (LCVD). An excimer laser (operating at 193 nm) was used as an excitation source. The LCVD process, was monitored in situ by optical emission spectroscopy (OES). READ MORE

  3. 3. Colloidal synthesis of metal oxide nanocrystals and thin films

    University dissertation from Institutionen för fysik, kemi och biologi

    Author : Fredrik Söderlind; Linköpings universitet.; Linköpings universitet.; [2008]

  4. 4. Synthesis, characterisation and applications of iron oxide nanoparticles

    University dissertation from Stockholm : Materialvetenskap

    Author : German Salazar Alvarez; KTH.; [2004]
    Keywords : Engineering and Technology Materials Engineering; Teknik och teknologier Materialteknik; Materials science; biochemistry; electricity and magnetism; optics; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : Further increase of erbium concentrations in Er-doped amplifiers and lasers is needed for the design of efficient, reliable, compact and cost-effective components for telecommunications and other photonic applications. However, this is hindered by Er concentration dependent loss mechanism known as upconversion. READ MORE

  5. 5. Engineered core - shell nanoparticles: synthesis, characterisation, and biocompatibility studies

    University dissertation from Stockholm : Karolinska Institutet, Institute of Environmental Medicine

    Author : Carmen Mihaela Vogt; Karolinska Institutet.; Karolinska Institutet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Superparamagnetic iron oxide nanoparticles (SPIONs) have emerged as promising contrast agents for Magnetic Resonance Imaging (MRI). Some SPIONs are already approved for clinical use. Coating of these nanoparticles with an additional biocompatible layer serves to improve the colloidal stability and biocompatibility. READ MORE
