  1. 26. Fluorescence Guided Resection of Brain Tumors : Evaluation of a Hand-held Spectroscopic Probe

    Författare :Johan Richter; Karin Wårdell; Jan Hillman; Peter Siesjö; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Malignant gliomas grow infiltrative in the brain and can therefore not be completely removed by neurosurgical means. However, for an optimized oncological treatment it has proven useful to resect as much as possible of tumor. The identification of the tumor in the marginal zone is difficult but crucial. LÄS MER

  3. 27. Atom Probe Tomography of Hydrogen and of Grain Boundaries in Corroded Zircaloy-2

    Författare :Gustav Sundell; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; corrosion; Field adsorption.; Hydrogen pick-up; Hydrogen analysis; Zirconium alloys; Atom probe tomography;

    Sammanfattning : Due to their low thermal neutron capture cross-section, zirconium alloys are widely used in the nuclear industry for fuel cladding and structural components. The lifetime of the fuel assemblies in the reactors are largely dictated by the ability of the fuel cladding to withstand corrosion and mechanical damage. LÄS MER

  4. 28. Modeling of non-equilibrium scanning probe microscopy

    Författare :Alexander Gustafsson; Magnus Paulsson; Tchavdar Todorov; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scanning tunneling microscopy; molecular dynamics; density functional theory; non-equilibrium Green s functions; Condensed Matter Physics; Kondenserade materians fysik;

    Sammanfattning : The work in this thesis is basically divided into two related but separate investigations.The first part treats simple chemical reactions of adsorbate molecules on metallic surfaces, induced by means of a scanning tunneling probe (STM). The investigation serves as a parameter free extension to existing theories. LÄS MER

  5. 29. Padlock Probe-Based Nucleic Acid Amplification Tests : Point-of-care Diagnostics of Infectious Diseases

    Författare :Sibel Ciftci; Mats Nilsson; Jonas Klingström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nucleic Acid Amplification; Isothermal Amplification Methods; Padlock Probes; Rolling Circle Amplification; Molecular Diagnostics; Infectious Disease Diagnostics; Virus; Point-of-Care; Biochemistry; biokemi;

    Sammanfattning : Recent advancements in molecular biology and biotechnology have pushed the field of molecular diagnostics much further to benefit the society towards smart access for rapid and simplified health care. In this context, point-of-care (PoC) technologies that bring the inventions in diagnostics closer to bedside settings draw attention. LÄS MER

  7. 30. Atom Probe Tomography of TiSiN Thin Films

    Författare :David Engberg; Lars Hultman; Magnus Odén; Fang Liu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns the wear resistant coating TiSiN and the development of the analysis technique atom probe tomography (APT) applied to this materials system. The technique delivers compositional information through time-of-flight mass spectrometry, with sub-nanometer precision in 3D for a small volume of the sample. LÄS MER
