  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. On Surface Topography of Cylinder Liners

    Author : Zlate Dimkovski; John Westberg; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder liner; Surface Roughness; Characterisation; Honing; Wear; Blechmantel; Groove Parameters; Quality Control; Flow Simulation; Surface engineering; Ytbehandlingsteknik;

    Abstract : The frictional losses, oil consumption and emissions in internal combustion engines are in great extent controlled by the cylinder liner surface topography. This emphasises the importance of: investigating the liner’s topography by objectively characterising it, investigating its effects on the tribological function to gain a better understanding and improving its manufacturing.

  5. 3. Modelling and Characterisation of Granular Material Flow

    Author : Simon Larsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Granular materials are very common both in nature and in industry, and their extensive use means that there are financial incentives for increased efficiency. There are huge costs related to their use and handling, which is a major motivation for increased knowledge of the behaviour of granular materials at different loading conditions. READ MORE

  6. 4. Image-based quantitative infrared analysis and microparticle characterisation for pulp and paper applications

    Author : Kari Hyll; Lars Mattsson; Hannes Vomhoff; Samuel Schabel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metrology; stock; papermaking; refining; fibrillation; fines; filler; morphology; classification; flow microscopy; fibre analyser; flow cytometry; laser diffraction; dynamic image analysis; process variation; thermography; emittance; emissivity; infrared; MWIR; LWIR; goniometer; Production Engineering; Industriell produktion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Measurements of process variations and particle morphology are widely employed in the pulp and paper industry. Two techniques with high potential, infrared thermography and microparticle characterisation, are mainly used qualitatively. READ MORE

  7. 5. Asymmetrical Flow Field-Flow Fractionation in the Application to Biological Macromolecules

    Author : Cecilia Arfvidsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Bioteknik; Biotechnology; biotechnology; recombinant protein production; molecular weight; Escherichia coli; ribosomes; glutenin; asymmetrical flow field-flow fractionation; multiangle light scattering;

    Abstract : Asymmetrical flow field-flow fractionation (AsFlFFF) is especially useful in the application to biological macromolecules due to the absence of a stationary phase in the separation channel. As a result no upper exclusion limit occurs and low shear forces affect the sample components. READ MORE
