1. 1. Theoretical Studies of Surface Forces and Phase Equilibria

   Författare :Jan Forsman; Kemiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; density functional theory; simulations; phase equilibria; hydrophobic interactions; hydration; Fysikalisk kemi; Physical chemistry;

   Sammanfattning : The interaction between large hydrophobic and hydrophilic surfaces in aqueous solution is investigated, using Metropolis Monte Carlo simulations and density functional theory. Special attention is devoted to the solvation force and its dependence on the nature of the solvent-solvent and solvent-surface interactions. LÄS MER

3. 2. Computer Simulations of Polymer Gels : Structure, Dynamics, and Deformation

   Författare :Natasha Kamerlin; Christer Elvingson; Jan Forsman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer simulations; Brownian dynamics; polymer gel; microgel; spherical boundary conditions; hypersphere; core-shell; deswelling; mechanical properties; uniaxial elongation;

   Sammanfattning : This thesis presents the results of computer simulation studies of the structure, dynamics, and deformation of cross-linked polymer gels. Obtaining a fundamental understanding of the interrelation between the detailed structure and the properties of polymer gels is a challenge and a key issue towards designing materials for specific purposes.

4. 3. Interfacial properties of calcium montmorillonite in aqueous solutions : Density functional theory and classical molecular dynamics studies on the electric double layer

   Författare :Guomin Yang; Göran Lindbergh; Ivars Neretnieks; Michael Holmboe; Jan Forsman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clay minerals; Bentonite; density functional theory; molecular dynamics; GROMACS; electric double layer; electrolytes; ionic liquids; primitive model; CLAYFF forcefield.; Chemical Engineering; Kemiteknik;

   Sammanfattning : The swelling properties of Bentonite are highly affected by clay content and the clay-water interactions that arise from the ion distribution in the diffuse double layer formed near the charged montmorillonite (or smectite) surfaces. Existing continuum models describing the electric double layers, such as classical Poisson-Boltzmann and DLVO theory, ignore the ion-ion correlations, which are especially important for multivalent ions at high surface charge and ionic strength.

5. 4. Skolans texter mot mobbning : reella styrdokument eller hyllvärmare?

   Författare :Arne Forsman; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pedagogik; Education;

   Sammanfattning : The aim of this doctoral thesis is to describe, analyse and interpret what is expressed in the comprehensive school’s texts against peer bullying. Express in this study means how international conventions, laws and school documents, research in the field and organisations against peer bullying, influence the content of the school texts against peer bullying.

7. 5. Suggestions for innovation in the supplying of joinery products through the application of Lean-thinking and 3-D sensing

   Författare :Samuel Forsman; Jakob Rehme; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Sammanfattning : The supplying of engineer-to-order joinery products to the construction industry is a novel research area in both the wood-related and the construction-related fields. The process of supplying the construction industry with highly refined one-of-a-kind wood products is here examined in order to explore possible process innovations to identify factors contributing to inefficiency, to define areas for innovation to improve industry performance, and to evaluate 3-D sensing technologies as a way of achieving a model-based joinery production.
