    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MOF; water oxidation catalyst; RBS; PSE; depth profiling; SURMOF; Kemi; Chemistry;

    Sammanfattning : In this thesis, selected synthetic aspects of functional Metal-Organic Frameworks (MOFs) are considered. More specifically, the work is focused on MOFs doped with functional molecules in the role of structural linkers. LÄS MER

  3. 2. Development of Techniques for 3D Imaging with Focused Ion Beams - Hydrogen Depth Profiling and Microtomography with Applications in Geology

    Författare :Marie Wegdén; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrogen analysis; Depth profiling; Ion beam analysis; Nuclear microprobe; Physics; Nuclear physics; Fysik; Fysicumarkivet A:2007:Wegdén; Kärnfysik; Tomography; 3D Imaging;

    Sammanfattning : In nuclear microprobe experiments, high resolution maps of the measured parameter, e.g. element- or mass distribution, in a sample can be produced with a variety of ion beam analytical techniques. The principle underlying all the techniques is that ions at MeV energies are used as projectiles to cause interactions with the target material. LÄS MER

  4. 3. Depth Profiling of the Passive Layer on Stainless Steel using Photoelectron Spectroscopy

    Författare :Wendy Fredriksson; Kristina Edström; Fredrik Björefors; Sannakaisa Virtanen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; depth profile; stainless steel; passive film; XPS; HAXPES; corrosion; powder metallurgical; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : The physical properties of the protective passive films formed on the surface of stainless steels under electrochemical polarization in different electrolytes were studied. The structure of these films was analyzed as a function of depth using photoelectron spectroscopy (PES). LÄS MER

  5. 4. Profiling the cancer proteome

    Författare :Sofia Waldemarson; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytologi; onkologi; cancer; Biotechnology; Bioteknik; cancerology; oncology; Cytology; iTRAQ; biomarkers; DIGE; two-dimensional gel electrophoresis; Proteomics;

    Sammanfattning : Cancer is a complex and heterogeneous disease where cells have started to grow uncontrolled and this disease remains a major health problem. Because of diffuse symptoms it often presents at a late stage. LÄS MER

  7. 5. Free Volume Depth Profiling at Polymer Surfaces and Interfaces

    Författare :John Algers; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymerteknik; Polymer technology; polymer interfaces; polymer surfaces; positron lifetime; free volume;

    Sammanfattning : Pulsed low energy positron beams provide a unique and non-destructive tool to depth probe the free volume of polymers at surfaces and interfaces. Since the employment of low energy positron beams in polymer research is an emerging technique, some focus in this thesis has been on extracting methods and equations needed to interpret the experimental data.
