  2. 1. 3d Transition Metals Studied by Mössbauer Spectroscopy

    Author : Saeed Kamali-Moghaddam; Roger Wäppling; Lennart Häggström; Friedrich Wagner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Mössbauer Spectroscopy; SQUID Magnetometry; XRD; Layered Structures; Magnetism; Magnetic Superlattices; Nanoparticles; Li-ion Batteries; Brass; Fysik; Physics; Fysik;

    Abstract : Layered crystals with magnetic elements as Co and Fe have been studied. In TlCo2Se2, where Co atoms in one sheet are separated by Tl and Se from the next Co sheet, magnetic interaction within and between the sheets have been studied. READ MORE

  4. 2. Adsorption and surface reaction properties of synthesized magnetite nano-particles

    Author : Payman Roonasi; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : The surface chemistry of inorganic materials is of great significance in a number of industrially important processes such as separation of ore by flotation, catalysis, water purification, paper coating and pharmaceutical industry. The purpose of this study has been firsly to develop a method for optimal synthesis of magnetite nanoparticles and secondly to utilize these particles as adsorbent in order to investigate their adsorption/desorption properties.

  6. 4. Scanning probe microscopy studies of interaction forces between particles: emphasis on magnetite, bentonite and silica

    Author : Illia Dobryden; Neil Thomson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Abstract : Scanning probe microscopy (SPM), such as the atomic force microscope (AFM), using colloidal probes is a highly suitable technique to probe single particle-particle interactions in aqueous solution. The interaction force between a colloidal probe on the AFM cantilever and sample surface is measured. READ MORE

  7. 5. Applications of nanotechnology in neuroscience : functionalized superparamagnetic nanoparticles as contrast enhancers in experimental magnetic resonance imaging

    Author : Fu-Hua Wang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Magnetic resonance imaging (MRI) is a noninvasive imaging technique that helps clinicians not only to diagnose but also to plan the treatment of invasive surgery and actually treat medical conditions. Superparamagnetic iron oxide nanoparticles (SPIONs) are a family of MRI contrast agents that improves MRI sensitivity/specificity. READ MORE
