  2. 1. The influence of particle shape of coating pigments on their packing ability and on the flow properties of coating colours

    Author : Sven Lohmander; KTH; []
    Keywords : aspect ratio; capillary viscometry; coating colour; filtration. Particle packing;

    Abstract : The influence of particle shape of coating pigments on theirpacking ability and on the flow properties of coating colourshas been investigated. The particle shapes considered werespherical, flaky and acicular (needle-shaped). READ MORE

  4. 2. Flow, expansion and processing behaviours of gas-containing filled polyethylene

    Author : Nabil Khoshaba; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical properties; flow rate; critical pressure; injection moulding; expansion kinetics; fillers; rheological properties; foaming; composite materials; partial pressure; capillary viscometry; Blowing agent;

    Abstract : The utilization of fillers in polymeric materials has exhibited a substantial growth during the last decades. Chalk (calcium carbonate) and glass fibres are two common examples of such fillers. These fillers/reinforcing elements are used in order to reduce the cost of material and change its physical (mechanical) properties. READ MORE

  5. 3. Erythrocyte deformability studies by viscometry and filtrometry

    Author : Sylvi Persson; Pavo Hedner; Bo Sandhagen; Sweden Lund University Hospital of Lund Department of Medicine; []
    Keywords : Erythrocyte deformability; viscometry; Filtrometry; Red cell membrane; Buffer; Filtration pressure; stress factors; Mean corpuscular volume; Sodium-potassium pump; Ouabain; Corticosteroids; Blood storage; Transfusion; MEDICINE; MEDICIN;

    Abstract : DOCTORAL DISSERTATION  Abstract The present thesis concerns factors of major importance in filtrometric studies of human erythrocytes, e.g. influence of buffer media, importance of filtration pressure for filtration through micropores and possible effects of damaged and hemolyzed blood cells.

  6. 4. Alkylglycoside Surfactants - Self-Assembly, Solid-State Properties and Interactions with Hydrophobic Molecules

    Author : Caroline Ericsson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; peptide stabilisation; solubilisation; micelle morphology; solid-state behaviour; alkylglycosides; nonionic surfactants;

    Abstract : A thorough physical-chemical characterisation of alkylglycosides has been performed. The effects of temperature, salt, concentration and deuterium exchange on the self-aggregation of n-nonyl-b-D-glucoside (b-C9G1) and n-tetradecyl-b-D-maltoside (b-C14G2) have been studied in dilute solutions by static and dynamic light scattering, neutron scattering, rheology, capillary viscometry and tensiometry.

  7. 5. On processing of thermoplastic starch

    Author : Mats Thunwall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amylose; starch; extrusion; thermoplastic starch;

    Abstract : Starch is a biodegradable material produced in many different crop plants. Since it is biodegradable, inexpensive, generally has good barrier properties and comes from a renewable source it would be an ideal material to use in e.g. packaging applications. READ MORE
