  1. 21. Synthesis of Mesoporous Silica and their Use as Templates for Metal and Metal Oxide Nanoparticles

    Författare :Mohamed A. Ballem; Magnus Odén; José M. Córdoba; Fredrik Söderlind; Lennart Bergström; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis covers the synthesis and characterization of two types of mesoporous silica, SBA-15 silica with two-dimensional hexagonal arrangement, and SBA-16 silica with three-dimensional cubic arrangement. The obtained mesoporous materials were then used as hard templates for synthesizing of different types of nanostructures. LÄS MER

  3. 22. Development of Novel Diffusion NMR Methods : Preclinical Applications in Colloidal Model Systems

    Författare :Stefanie Eriksson; Fysikalisk kemi; []
    Nyckelord :diffusion NMR; diffusion tensor; Microscopic anisotropy; q-MAS; exchange; liquid crystals; yeast cell suspensions;

    Sammanfattning : NMR is a powerful non-invasive technique utilizing radiofrequency and gradient pulses to manipulate the spinsof atomic nuclei. In particular, diffusion NMR uses strong magnetic field gradients to label the positions of spins allowing for the measurement of translational motion of molecules in liquids. LÄS MER

  4. 23. Effect of Physical Weathering on Mechanical Properties of Tailings

    Författare :Juan Rodriguez; Kauko Kujala; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : The mining activity produces minerals to supply to the modern society with commodities. During the ore refining process large amounts of tailings are generated as waste. Tailings are the result of crushing and wet milling, typically in the size range of sand to silt and angular in shape. LÄS MER

  7. 25. From experiments with images to 3D models

    Författare :Henrike Häbel; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colloidal particle aggregation; Anisotropy; mass transport; image analysis; Gibbs point processes; porous polymer blended films; porous polymer blended films;

    Sammanfattning : For developing the next generation sustainable materials, it is often crucial to understand and control their properties and function. This work presents cross-disciplinary research starting with experimentally fabricated porous soft biomaterials and images of their micro-structure obtained by electron or laser microscopy. LÄS MER
