  1. 1. Rheological Behaviour of Biopolymer Gels in Relation to Structure

    Author : Mats Stading; Chalmers University of Technology; []
    Keywords : particulate gels; fine-stranded gels; mixed gels; biopolymer gels; inhomogeneous gels; rheological properties; rheological behaviour;

    Abstract : 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. READ MORE

  2. 2. Rheological properties of lubricating fluids

    Author : Jan Lundberg; []

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 5. Rheological and mechanical properties of systems containing nanocellulose

    Author : Tobias Moberg; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Shear rheology; Cellulose nanocrystals; Cellulose nanofibrils; Mechanical properties; Dynamic-mechanical analysis; Composites; Extensional rheology;

    Abstract : Nanocellulose is a cellulose entity at the nanoscale. There are several different types of nanocellulose such as cellulose nanofibrils (CNF), which are long, somewhat flexible fibrils and cellulose nanocrystals (CNC), which are shorter and more rod-like particles. READ MORE
