    Författare :Derrick C. Mancini; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : .... LÄS MER

  2. 2. Small science on big machines: Politics and practices of synchrotron radiation laboratories

    Författare :Olof Hallonsten; Research Policy Institute (RPI); []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; big science; little science; sophistication; collectivization; European Synchrotron Radiation Facility; Stanford Synchrotron Radiation Lightsource; MAX-lab; scientific entrepreneurs; changing dynamics of science; Synchrotron radiation; research policy; science policy;

    Sammanfattning : Synchrotron radiation laboratories are large scientific facilities where various scientific experiments are carried out by the use of radiation produced by particle accelerators. Research with synchrotron radiation emerged in the 1960s and 1970s as a peripheral activity at particle physics laboratories. LÄS MER

  3. 3. Synchrotron-based characterization of mechanobiological effects on the nanoscale in musculoskeletal tissues

    Författare :Isabella Silva Barreto; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoscale; microscale; mechanical properties; synchrotron; x-ray imaging; collagen; hydroxyapatite; biomechanics; experimental mechanics; x-ray tomography; small-angle x-ray scattering SAXS ; wide-angle x-ray scattering WAXS ; x-ray fluorescence XRF ; small-angle x-ray scattering tensor tomography SASTT ; Fourier-transform infrared spectroscopy FTIR ; polarized light microscopy PLM ; bone development; Achilles tendon; tendon healing;

    Sammanfattning : Collagen is the main organic building block of musculoskeletal tissues. Despite collagen being their smallest load bearing unit, these tissues differ significantly in mechanical function and properties. A major factor behind these differences is their hierarchical organization, from the collagen molecule up to the organ scale. LÄS MER

  4. 4. Nuclear motion in molecular ions studied with synchrotron radiation and multicoincidence momentum imaging spectrometry

    Författare :Joakim Laksman; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecule; synchrotron;

    Sammanfattning : A momentum imaging spectrometer optimized for photoionization experiments with synchrotron radiation was built in 2008. The spectrometer is equipped with an electrostatic lens, that focuses the charged dissociation products on to a position-sensitive multi-hit delay line anode. LÄS MER

  5. 5. The Formation and Breakdown of Passive Film on Ni Alloys : in situ synchrotron studies

    Författare :Alfred Larsson; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Passivity; Corrosion; Degradation; Nickel alloys; synchrotron; in situ; Fysicumarkivet A:2023:Larsson;

    Sammanfattning : Corrosion results in huge annual costs and a large environmental footprint. The corrosion rate of some alloys can be made negligible by the presence of a spontaneously forming oxide film on the surface, a so-called passive film. Famous examples of alloys exhibiting passivity are stainless steels. LÄS MER
