  2. 1. Size Characterisation of Water-Soluble Polymers Using Asymmetrical Flow Field-Flow Fractionation

    Author : Bengt Wittgren; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multi-angle light scattering; molar mass distribution; aggregation; size characterisation; Asymmetrical flow FFF; water-soluble polymers; polysaccharides; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : Size, as expressed by molar mass, radius of gyration or hydrodynamic radius, for example, is a fundamental parameter of polymers in solution. Thus, there is a strong need for the characterisation of both the size and shape of polymers, particularly of those utilised in various industrial applications. READ MORE

  4. 2. InGaAs-based quantum dots for infrared imaging applications : growth and characterisation

    Author : Linda Höglund; Per-Olof Holz; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In this thesis, results are presented from the development of quantum dot (QD) based infrared photodetectors (IPs). This includes epitaxial growth of QDs, investigations of the structural, optical and electronic properties of the QD based material as well as characterisation of the resulting components. READ MORE

  5. 3. Characterisation of residues : Release of contaminants from slags and ashes

    Author : Ann-Marie Fällman; Rob N.J. Comans; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Residues from industrial processes as well as from energy production utilities have in many cases properties similar to geological materials. They can be used as filling and construction materials if the net environmental impact and the technical properties are acceptable. READ MORE

  6. 4. Silicon and Quartz Microengineering : Processing and Characterisation

    Author : Örjan Vallin; Peter Enoksson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; silicon; quartz; microengineering; microstructure; MEMS; wafer bonding; direct bonding; adhesion quantification; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : Microengineering has developed a broad range of production techniques to reduce size, increase throughput, and reduce cost of electrical and mechanical devices. The miniaturisation has also entailed entirely new opportunities. READ MORE

  7. 5. Lignin polysaccharide networks in softwood and chemical pulps : characterisation, structure and reactivity

    Author : Martin Lawoko; Göran Gellerstedt; Gösta Brunow; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : The chemical interactions between the main wood components i.e., cellulose, hemicelluloses and lignin are of fundamental importance for understanding the chemical aspects of wood formation and its reactivity during fibre processing e.g during chemical pulping of wood. READ MORE
