  1. 1. Characterization and Clinical Application of Normoxic Polymer Gel in Radiation Therapy Dosimetry

    Författare :Anna Karlsson; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D dose verification; uncertainties; low-density gel; fractionation dependence; characterization; normoxic gel; polymer gel dosimetry; MRI; Physics; Fysik;

    Sammanfattning : Cancer is one of the main causes of death in the world, particularly in developing countries and is considered as a major public health problem. Radiation therapy has been an important modality for treatment of cancer for many decades. LÄS MER

  2. 2. Rheology and UV-curing of a star-branched polyester

    Författare :Hans Claesson; KTH; []
    Nyckelord :Powder coating; UV-curing; star-polymer; gel point; alipahtic polyester; rheology; dendritic;

    Sammanfattning : The use of powder coatings has increased steadily over thelast few decades. Their popularity is due to a number of majoradvantages they offer when compared to solvent-borne systems.Near zero VOC-content, reduced energy consumption and near 100%utilisation of the material are some of the advantages.

  3. 3. Nitride fuel production by the internal sol gel process

    Författare :Marcus Hedberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitride fuels; ZrN; internal sol gel;

    Sammanfattning : AbstractDuring operation of a fourth generation reactor system it is necessarily not desirable to utilize an oxide fuel matrix as in light water reactor systems. One type of chemical compounds that has been suggested is nitride based nuclear fuel. LÄS MER

  4. 4. Characterization of Micro-Structures in Materials

    Författare :Henrike Häbel; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Clustering; colloidal nanoparticle gels; image analysis; mass transport; point pattern; polymer blended films; pore shape; polymer blended films;

    Sammanfattning : On developing the next generation sustainable soft materials, it is often crucial to understand and control their properties and function. Whereas a characterization of three-dimensional data is desirable in corresponding studies, often two-dimensional data are less time consuming to obtain. LÄS MER

  5. 5. 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
