  1. 41. Properties of poly(lactic acid) in presence of cellulose and chitin nanocrystals

    Författare :Shikha Singh; Kristiina Oksman; Maria Lluisa Maspoch; Alfonso Jiménez; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poly lactic acid ; chitin nanocrystals; nanocellulose; crystallization; orientation; nanocomposites; mechanical properties-other properties; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : Plastic based materials are widely used for industrial and domestic packaging application. However, disposal of such petroleum-based materials e.g. polyethylene (PE), polypropylene (PP), and polyethyleneterephthalate (PET) has become a huge threat to the environment. LÄS MER

  3. 42. Spectroscopic and elastic properties in metallic systems from first-principles methods

    Författare :Christian Asker; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : In this thesis, ab initio calculations on metallic systems are presented. The overall aim is to probe properties that are often considered to be difficult to obtain within the framework of density-functional theory. The aim has also been to chose problems and systems that are of a wider interest and not only a testbed for calculations. LÄS MER

  5. 44. Microstructure and rheological properties of plant particle suspensions prepared using different physical treatments

    Författare :Patricia Lopez-Sanchez; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; yield stress; rheology; elastic modulus; cell wall; tomato; broccoli; plant particle suspension; microstructure; carrot;

    Sammanfattning : Suspensions of plant particles are very common products or by-products in many industries such as food, paper and biofuel. An improved understanding of the complex relationship between microstructure and rheology of these plant systems might help design, control and predict their structural and material properties.

  7. 45. Influences of the Graphite Phase on Elastic and Plastic Deformation Behaviour of Cast Irons

    Författare :Torsten Sjögren; Ingvar L. Svensson; Sten Johansson; Jorge Sikora; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; Flake graphite; Compacted graphite; Spheroidal graphite; Elastic deformation; Plastic deformation; Modulus of elasticity; Graphite modulus of elasticity; Strength coefficient; Strain hardening exponent; Acoustic emission; Construction materials; Konstruktionsmaterial;

    Sammanfattning : The amount and morphology of the graphite phase largely controls the resulting properties of cast iron. For instance, in flake graphite cast irons the mechanical properties are low while the thermal conductivity is high. LÄS MER
