  3. 2. Quantitative electron probe X-ray microanalysis of biological specimens

    Författare :Godfried M. Roomans; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The application of quantitative methods in electron probe X-ray microanalysis of biological specimens expands the scope of this technique. Accurate quantitation in biological X-ray microanalysis is not easy and a number of difficulties is typical for biological specimens. LÄS MER

  4. 3. Development of Cermet Microstructures during Sintering and Heat-Treatment

    Författare :Jenni Zachrisson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; APFIM; EELS; cemented carbides; quantitative microanalysis; gradients; N ; TEM; EFTEM; hardmetals; EDX; Ti C; light elements;

    Sammanfattning : The work presented in this thesis is concerned with the microstructure of Ti(C, N) based cermet materials used in cutting tool applications. Several techniques have been used to study the microstructure of cermets, in particular transmission electron micro-scopy in combi-na-tion with energy dispersive X-ray analysis and electron energy-loss spectroscopy, energy-filtered transmission electron micro-scopy, atom-probe field-ion microscopy and scanning electron microscopy.

  5. 4. Atomic Scale Degradation of Zirconium Alloys for Nuclear Applications

    Författare :Gustav Sundell; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Irradiation damage; Hydrogen microanalysis; Hydrogen pick-up; Zirconium alloys; Atom probe tomography; Corrosion;

    Sammanfattning : Due to their low thermal neutron capture cross-section, zirconium alloys are widely used in the nuclear industry as fuel cladding and for structural components. The lifetime of the fuel assemblies in the reactors is primarily dictated by the ability of the cladding to withstand oxidation and hydrogen pick-up from the coolant water and radiation damage induced by the neutron flux.

  7. 5. Methods in electron microscopic quantitative immunocytochemistry using adenohypophysis as a model

    Författare :Barbara Kniola; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Quantitative ultrastructural immunocytochemistry (QUIC) is based on the assessment of immunogold labeling over the surface of ultrathin resin-embedded sections. The density of specific labeling, expressed as the number of gold particles/mm2 of a specific area can only be used as an approximative estimation of antigen concentration in the object. LÄS MER
