  2. 1. Adsorption, aggregation and phase separation in colloidal systems

    Author : Jing Dai; Istvan Furo; Peter Griffiths; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; chemical shift; spin relaxation; self-diffusion; micelle; core freezing; segregation; solubilization; release; adsorption; binding; surfactant; carbon nanotube; block copolymer; dispersion; competitive adsorption; nanocomposite; Kemi; Chemistry;

    Abstract : The thesis presents work regarding amphiphilic molecules associated in aqueous solution or at the liquid/solid interface. Two main topics are included: the temperature-dependent behavior of micelles and the adsorption of dispersants on carbon nanotube (CNT) surfaces. READ MORE

  4. 2. Molecular Association Studied by NMR Spectroscopy

    Author : Lars Nordstierna; István Furó; Peter Griffiths; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; spin relaxation; self-diffusion; intermolecular cross-relaxation; chemical shift; fluorinated surfactants; hydrogenated surfactant; micelle; non-ideal mixing; adsorption; hydration; surfactant-protein association; Physical chemistry; Fysikalisk kemi;

    Abstract : This Thesis presents studies of molecular association in aqueous solution and at the liquid/solid interface. The investigated molecular systems range from self-aggregating surfactants to hydration water in contact with micelles or individual molecules. In most studies, combinations of various NMR methods were applied. READ MORE

  5. 3. Direct and indirect magnetocaloric properties of first- and second-order phase transition materials

    Author : Sagar Ghorai; Peter Svedlindh; Martin Sahlberg; Gabriella Andersson; Ekkes Brück; Uppsala universitet; []
    Keywords : Magnetocaloric effect; Adiabatic temperature change; Direct measurement of magnetocaloric effect; Griffiths phase; Magneto-elastic transition; Magneto-structural transition; Second-order magnetic phase transition; First-order magnetic phase transition; Isothermal magnetic entropy change; Fysik; Physics;

    Abstract : The energy-efficient and environmentally friendly alternative cooling technology based on the magnetocaloric effect (MCE) is discussed in this thesis. The thesis has two major parts, one devoted to material characterization and the other to instrument development. READ MORE

  6. 4. In conversation with simulation: The application of numerical simulation to the design of structural nodal connections

    Author : Jens Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; 3D Printing; Design theory; Structural design; Structural efficiency; Simulation; Peridynamics; Force flux density; Nodal connections; Conceptual design; Steel structures; Design process; Digital design;

    Abstract : The thesis explores methods for integration of structural analysis, design and production in a digital design environment. The somewhat ambiguous title implies the ambition to make such integration in relation to the explorative phase of the design process which is described by Donald Schön as having a conversational character.
