  1. 1. Theoretical Investigations of the Role of Ion-Ion Correlations and Ion-Specific Interactions in Electric Double Layers

    Författare :Erik Wernersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electric double layers; Electrolyte solutions; Ion-ion correlations; Dispersion forces; Colloidal interactions; Charge inversion; Continuum models;

    Sammanfattning : Electric double layers are ubiquitous, arising in some form in almost every situation involving an interface with an aqueous electrolyte solution. In order to gain insight into the behavior of electrolytes and electric double layers, simple models of bulk and inhomogeneous electrolyte solutions are considered in this thesis. LÄS MER

  3. 2. Operating Organic Electronics via Aqueous Electric Double Layers

    Författare :Henrik Toss; Magnus Berggren; Edwin Jager; Daniel Simon; Annalisa Bonfiglio; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The field of organic electronics emerged in the 1970s with the discovery of conducting polymers. With the introduction of plastics as conductors and semiconductors came many new possibilities both in production and function of electronic devices. LÄS MER

  4. 3. Mixed mode loaded adhesive layers : from measurement of material data to analysis of structural behaviour

    Författare :Jia Li Högberg; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; mixed mode testing; cohesive law; J-integral; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

    Sammanfattning : In manufacturing of multi-material products, a joining method that is able to cost-effectively assemble components made of dissimilar and similar material, with irregular geometries, is optimal. As an alternative, adhesive bonding is in-creasingly adapted by the industry, which is also used in manufacturing of multi-phase materials. LÄS MER

  5. 4. Shear walls with double plasterboards : evalutation of design models

    Författare :Tomas Filipsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : This thesis presents a part of the ECSC-project Development of dry composite construction systems based on steel in residential application that focus on design recommendations for stabilizing buildings by using shear resistance in the walls. The existing design method suggested and used by the Swedish plasterboard manufacturer Gyproc AB is considered as a bit conservative and it does not consider double plasterboards properly. LÄS MER

  7. 5. Mechanical behaviour of adhesive layers : experimental methods, cohesive laws, and fracture mechanics

    Författare :Anders Biel; Kristofer Gamstedt; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental method; adhesive layer; cohesive law; fracture; fracture energy; energy release rate; peel; shear; Materials science; Teknisk materialvetenskap; Teknik; Technology;

    Sammanfattning : Adhesive joining is today viewed as one of the key technologies to achieve decreased emissions in the automobile industry. To decrease weight, optimal material selection often results in different materials for different parts. This leads to the necessity to join mixed material. Here, the use of adhesives is the most promising joining technology. LÄS MER
