    Sammanfattning : Since their discovery about 100 years ago, tools made of hard metals have been the enablers of development in various areas: from drilling subway lines for more sustainable cities to the machining of complex next-generation airplane engine parts for reduced CO2 emissions. An increase in properties of hard metals thus leads to efficient operations with shorter lead-time, less environmental footprint, and reduced cost. LÄS MER

  4. 3. Neutron Scattering at 96 MeV

    Författare :Angelica Öhrn; Jan Blomgren; Robert Haight; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; neutron; elastic scattering; inelastic scattering; differential cross section; optical model potential; Wick s limit; angular distribution; pre-equilibrium; Kärnfysik; Physics; Fysik;

    Sammanfattning : Data on elastic scattering of 96 MeV neutrons from 56Fe, 89Y and 208Pb in the angular interval 10-70° are presented. The previously published data on 208Pb have been extended, as a new method has been developed to obtain additional information at the most forward angles. LÄS MER

  5. 4. Bone structure characterisation using neutron scattering techniques

    Författare :Elin Törnquist; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomechanics; neutron tomography; x-ray tomography; small-angle neutron scattering SANS ; small-angle x-ray scattering SAXS ; Experimental mechanics; implant integration; tomography; nanoscale; microscale; mechanical properties;

    Sammanfattning : Bones have unique mechanical properties that originate from their main constituents: mineral, in the form of hydroxyapatite (HAp) crystals, and collagen type-I. The stiffness of the HAp mineral combined with the flexibility of collagen, and their intricate hierarchical arrangement from the smallest individual building blocks to the organ level, result in a composite tissue with a remarkable ability to withstand complex loading scenarios.
