    Författare :Hans Magnusson; Ulf Germgård; Gunnar Henriksson; Hans Theliander; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; kraft pulping; recovery boiler; smelt properties; non-process elements; oxygen delignification; viscose manufacturing; integrated production; regenerated cellulose; sulfatmassa; fysikaliska egenskaper; smälta; sodapanna; processfrämmande ämnen; bioraffinaderi; integrerad produktion; regenererad cellulosa; Chemical Engineering; Kemiteknik;

    Sammanfattning : Modern chemical technology is an efficient tool for solving problems, particularly within the complex environment of the pulp and paper industry, and the combination of experimental studies, mill data and mass balance calculations are of fundamental importance to the development of the industry. In this study various examples are presented, whereby chemical technology is of fundamental importance. LÄS MER

  4. 3. Compacted graphite iron : On solidification phenomena related to shrinkage defects

    Författare :Björn Domeij; Attila Diószegi; Babette Tonn; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compacted graphite iron; Spheroidal graphite iron; Solidification; Microsegregation; Porosity; Kompaktgrafitjärn; segjärn; stelning; mikrosegregation; porositet;

    Sammanfattning : An improved understanding of solidification of compacted graphite iron (CGI) is necessary to predict shrinkage related casting defects. Spheroidal graphite is not only found in ductile iron (SGI) but usually also in CGI, but its characteristics and role in this material is less understood. LÄS MER

  5. 4. On Fuel Coolant Interactions and Debris Coolability in Light Water Reactors

    Författare :Sachin Thakre; Weimin Ma; Florian Fichot; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; severe accident; fuel-coolant interactions; melt jet fragmentation; steam explosion; debris bed coolability; uncertainty analysis; Energiteknik; Energy Technology;

    Sammanfattning : During the case of a hypothetical severe accident in a light water reactor, core damage may occur and molten fuel may interact with water resulting in explosive interactions. A Fuel-Coolant Interactions (FCI) consists of many complex phenomena whose characteristics determine the energetics of the interactions. LÄS MER

  7. 5. Picosecond X-ray Diffraction Studies of Bulk and Nanostructure Materials

    Författare :Andrius Jurgilaitis; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solid-liquid transitions; X-ray diffraction and scattering; nanowires; laser beam impact phenomena; phonons in crystal lattices; Fysicumarkivet A:2012:Jurgilaitis;

    Sammanfattning : Fast phenomena occurring after laser excitation were studied using time-resolved X-ray diffraction (TXRD). In most experiments, a femtosecond laser pulse was used to excite the sample, and X-rays were used as a probe. LÄS MER
