  1. 6. Multiscale methods for simulation of paper making

    Författare :Gustav Kettil; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Paper making; Numerical upscaling; Lay down simulations; Virtual paper sheets; Fiber network model; Forming fabric flow; Fiber suspension flow; Fiber-fiber interaction; Multiscale methods; Fluid structure interaction;

    Sammanfattning : In this work, multiscale methods for simulation of paper making are developed. The emphasis is on simulation of the paper forming process and simulation of the mechanical properties of paper sheets. To simulate paper forming, a novel fiber-fiber interaction method is proposed.

  3. 7. Spontaneous imbibition and colloidal aspects of inkjet printing

    Författare :Asaf Oko; Per M. Claesson; Agne Swerin; Douglas Bousfield; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Water-based inkjet is one of the most abundant and versatile digital printing technologies. The subject of this thesis work is processes that take place once an inkjet drop lands on the surface of a porous printing media, with focus on liquid penetration due to capillary action (spontaneous imbibition) and aggregation of ink components.

  4. 8. Nanoparticle Self-assembly on Prefabricated Nano Strucutres

    Författare :Johnas Eklöf; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofabrication; Nanoparticles; single molecular electronics; Self-assembly;

    Sammanfattning : The demand for more powerful computers have been increasing ever since the first semiconducting devices were invented in the second half of the 20th century. The demand for an increase in computing power have escalated since the start of modern computer technology, however conventional techniques are reaching the limits regarding the downscaling of semiconducting based logic circuits.

  5. 9. Bacteria-sulfide mineral interactions with reference to flotation and flocculation

    Författare :Annamaria Vilinska; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Biological processes have been attracting attention in mineral processing industry due to their lower operating costs, environmental acceptability and flexibility in adaptation. Bio-hydrometallurgical methods to treat various sulfide and oxide ores have been developed during the years and these processes have been adopted by certain industries. LÄS MER

  7. 10. Studies on preparation and properties of nanophase metal oxides

    Författare :Tarja Turkki; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis is about science on an atomic scale - aninterdisciplinary approach to nanoparticles. Studies of thepreparation of nanoparticles using both physical and chemicalmethods are presented. Understanding and controlling factorsfor particle growth during synthesis are the keys to successfulfabrication of materials with tailored properties. LÄS MER
