  1. 1. Rheological Properties of Microfibrillated Cellulose

    Författare :Tobias Moberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological properties; creep; Extensional viscosity; Microfibrillated cellulose; suspensions; ;

    Sammanfattning : Cellulose has for a long time been used by man. It is renewable and an easily recyclable resource. Mostly it has been used in either its native form as wood or in the form of fibres. LÄS MER

  3. 2. Rheological Behaviour of Biopolymer Gels in Relation to Structure

    Författare :Mats Stading; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particulate gels; fine-stranded gels; mixed gels; biopolymer gels; inhomogeneous gels; rheological properties; rheological behaviour;

    Sammanfattning : The rheological behaviour of biopolymer gels with different network structures was studied to elucidate how the structure of the gel influences its rheological properties. Non-destructive viscoelastic measurements and fracture techniques were used. LÄS MER

  4. 3. Rheological properties of lubricating fluids

    Författare :Jan Lundberg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : Obliteration (gobbing) caused by water based lubricating fluids is studied experimentally by analyzing the flow through a small channel. Flow measurements, energy dispersive X-ray microscopy and photos show, that the rate of gobbing depends on which type of fluid that is being used. LÄS MER

  5. 4. SmCo for polymer bonded magnets : Corrosion, silanization, rheological, mechanical and magnetic properties

    Författare :Muhammad Irfan Qadeer; Steven Savage; Mikael Hedenqvist; Uta Klement; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organofunctional alkoxysilanes; High temperature oxidation; Rare-earth magnetic alloys; SmCo; Isothermal; Non-isothermal; Microstructure; Magnetic properties;

    Sammanfattning : This thesis presents the study of organofunctional alkoxysilane coatings to prevent high temperature oxidation of Sm-Co powders. Sm-Co are important permanent magnetic alloys, owing to their high Curie temperature and large values of magnetocrystalline anisotropy. LÄS MER
