  1. 11. Modelling anisotropic interactions in colloidal systems

    Författare :Alexei Abrikossov; Fysikalisk kemi; []
    Nyckelord :SIMULATION; Modelling; electrostatic interactions; Colloids; Statistical mechanics; SIMULATION; Modelling; electrostatic interactions; colloid; Statistical mechanics;

    Sammanfattning : There has been an increased interest to design “smart materials” which can self-assemble into complex structures in accordance to external factors such as for example electromagnetic fields. By designing particles with directional interactions one is able to control how particles will interact with each other. LÄS MER

  3. 12. Multimodal Imaging of Anisotropic Hierarchical Materials

    Författare :Adrian Rodriguez Palomo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biomaterials; Hierarchical Materials; Multimodal Imaging; Birefringence; X-Ray Scattering;

    Sammanfattning : The thesis is focused on studying the nanostructure of natural and synthetic hierarchical materials with biological applications, using X-ray scattering imaging and birefringence microscopy. The term "hierarchical materials" is used for structures composed of sub-units organised in different length scales that create the building blocks for the next level. LÄS MER

  5. 14. Optimal Estimation of Grain Orientation in an Anisotropic Weld by Ultrasonic Techniques

    Författare :Qingwei Liu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anisotropic weld model; multi-objective genetic algorithm; nonlinear optimization; ultrasonic probe model; 2D ray tracing;

    Sammanfattning : Grain orientation in an anisotropic weld highly influences ultrasound paths and thus is a significant parameter when making simulations of ultrasonic testing of anisotropic welds. Though each weld is thought to be unique in its structure, the common procedure in modeling is to prescribe the grain orientation in a weld based on limited experience. LÄS MER

  7. 15. Adhesion Characterization and Reliability Issues of Anisotropic Conductive Adhesives for Microsystem Applications

    Författare :Liqiang Cao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesion strength; curing degree and curing temperature; moisture effect; flip chip; anisotropic conductive adhesives; reliability;

    Sammanfattning : There has been a steadily increasing interest in using electrically conductive adhesives as interconnecting materials in electronics manufacturing. Simple processing, low bonding temperature and fine-pitch capability are the major advantages of conducting adhesive technology. LÄS MER
