  2. 21. Calcium Aluminate based Cement as Dental Restorative Materials

    Author : Lars Kraft; Charles Lloyd; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : This thesis presents the results from the development process of a ceramic dental filling material based on calcium aluminate cement. The main focus of the work concerns dimensional changes during setting, hardening and curing and the understanding of the factors controlling the dimensional stability of the system. READ MORE

  4. 22. Structure and properties of advanced fine grained steels produced using novel thermal treatments

    Author : Esa Vuorinen; David Porter; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Abstract : Fine grained advanced steels exhibit favourable mechanical properties for applications requiring high strength, ductility and impact toughness. These properties result from a microstructure containing a fine distribution of several phases including ferrite, austenite, martensite and bainite. READ MORE

  5. 23. Material modelling for simulation of heat treatment

    Author : Henrik Alberg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : Heat treatment of materials is a fundamental metallurgical process. Materials are subjected to heat treatment to relieve internal stresses, reduce brittleness and to improve machinability. The properties of materials can also be altered such as hardness, strength, toughness, and wear resistance to suit particular applications. READ MORE

  6. 24. Light scattering in pulp and paper

    Author : Tomas Linder; Risto Myllylä; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : The pulp and paper industry of today is facing a highly competitive market where manufacturers are constantly seeking ways to reduce costs as well as to improve product specifications and quality. On-line quality control is one of many areas being actively developed, from the wood delivered to the plant to the fibers in the finished product. READ MORE

  7. 25. Design, processing and properties of lightweight foams from cellulose nanofibers

    Author : Korneliya Gordeyeva; Lennart Bergström; Nathalie Lavoine; Monica Österberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cellulose nanofibers; lightweight foams; hybrid; Materials Chemistry; materialkemi;

    Abstract : Foams are applied in many areas including thermal insulation of buildings, flotation devices, packaging, filters for water purification, CO2 sorbents and for biomedical devices. Today, the market is dominated by foams produced from synthetic, non-renewable polymers, which raises serious concerns for the sustainable and ecological development of our society. READ MORE
