1. 16. Flow, expansion and processing behaviours of gas-containing filled polyethylene

   Författare :Nabil Khoshaba; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 17. Measuring Material Properties through Gradient Based NMR: Diffusion and Imaging

   Författare :Ingrid Åslund; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intracellular diffusion; homogeneous length-scale; material properties; emulsions; yeast suspensions; lamellar phase; NMR; self-diffusion; membrane permeability and bending rigidity;

   Sammanfattning : In this work new methods based Nuclear Magnetic Resonance (NMR) have been developed to measure different kinds of structural properties in soft materials. The advantage of using NMR as a technique to measure material properties is that it is non-destructive, which makes it possible to measure on the actual piece of material that will be used for the application.

4. 18. Making Pairs

   Författare :Jens Gudmundsson; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; equilibrium; existence; Pairing; matching; stability; algorithms;

   Sammanfattning : This thesis makes a contribution to matching theory. It consists of five self-contained papers. It is a study predominately on the existence of stable outcomes. These are desirable both from a practical and a theoretical standpoint. LÄS MER

5. 19. Thermodynamic Database for Zirconium Alloys

   Författare :Rosa Jerlerud Pérez; Bo Sundman; Arthur Motta; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zirconium alloys; thermodynamic equilibrium; thermodynamic properties; binary system; ternary system; Gibbs energy; Thermo-Calc; Calphad; binary system; ternary system; Other materials science; Övrig teknisk materialvetenskap;

   Sammanfattning : For many decades zirconium alloys have been commonly used in the nuclear power industry as fuel cladding material. Besides their good corrosion resistance and acceptable mechanical properties the main reason for using these alloys is the low neutron absorption. LÄS MER

7. 20. Characterization of an Electrical Sensor for Combustion Diagnostics

   Författare :Axel Franke; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ion sensor; combustion; nitric oxide; chemi-ionization; equilibrium; Physics; ionized gases; Fysicumarkivet A:2002:Franke; ionization sensor; Fysik;

   Sammanfattning : The ionization sensor is an electrical probe for diagnostics in internal combustion engines. The combustion process affects the electrical properties of the gas in the cylinder. Thus the sensor signal contains copious information about the conditions in the combustion chamber. LÄS MER
