  2. 16. Computational investigation of interface structure and composition in cemented carbides at finite temperatures

    Author : Erik Fransson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular dynamics; Hard Metals; Interfacial free energies; Monte Carlo; Cemented carbides; Force constants; Cluster expansion;

    Abstract : WC-Co cemented carbides combine superb hardness with high toughness making them ideal for usage in high-speed machining of steels and in wear resistance tools. These excellent mechanical properties are to a large extent dependent on the microstructure and thus the interfacial properties of the material. READ MORE

  4. 17. On the interaction between wort protein and iso-humulone : A study of surface rheology, interfacial structures and particle formation with the relevance to beer foam

    Author : Yi Lu; Avdelningen för livsmedel och läkemedel; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wort barley protein; lipid transfer protein; protein Z; iso-humulone; Ellipsometry; Surface rheology;

    Abstract : Beer is one of the most popular drinks in the world. Foam is a unique characteristic of beer, contributing to mouthfeelings and visual perceptions. Therefore, it would be worthwhile to study the solution and interfacial properties ofbeer and assess them with regards to foam. READ MORE

  5. 18. Surface chemical behaviour

    Author : Marie Wickman; KTH; []
    Keywords : ;

    Abstract : The objective of the investigations included in this thesisis to show how the properties of alkyd resins, used as bindersin offset printing inks, affect the ink in terms of pigmentdispersion, emulsification of fountain solution, and inksetting.The interactions between alkyd resins and aqueous solutionshave been investigated by interfacial tension measurementsusing the pendant drop technique and by measurement of dropletsize using light diffraction.

  6. 19. Characterisation of water-based floxographic inks and their interacitons with polymer-coated board

    Author : Maria Rentzhog; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi;

    Abstract : This licentiate thesis comprises two parallel studies dealing with water-based flexographic inks on PE-coated liquid packaging board. The commercial waterbased inks that were used in both studies vary in type of pigment and acrylatepolymer vehicle, and in pigment/vehicle mixing proportions. READ MORE

  7. 20. Matrix and interface effects on microcracking in polymer composites

    Author : Anders Sjögren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : An underlying industrial problem for the present work is leakage of pressure vessels. Fluid leakage was confirmed to take place along a path of connected microcracks and delaminations. The thesis is concerned with the micromechanisms for microcracking studied by in-situ optical microscopy of cross-ply laminates. READ MORE
