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

    Author : German Salazar Alvarez; Manoun Muhammed; Jarl B. Rosenholm; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; biochemistry; electricity and magnetism; optics; Materialvetenskap; Materials science; 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. 3. Crystallization on the Mesoscale : Self-Assembly of Iron Oxide Nanocubes into Mesocrystals

    Author : Michael Agthe; Lennart Bergström; German Salazar-Alvarez; Tommy Nylander; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; iron oxide nanocubes; mesocrystal; small angle X-ray scattering; video microscopy; QCM-D; Materials Chemistry; materialkemi;

    Abstract : Self-assembly of nanoparticles is a promising route to form complex, nanostructured materials with functional properties. Nanoparticle assemblies characterized by a crystallographic alignment of the nanoparticles on the atomic scale, i.e. mesocrystals, are commonly found in nature with outstanding functional and mechanical properties.
