  1. 1. Surfaces Designed for High and Low Friction

    Författare :Ulrika Pettersson; Staffan Jacobson; Roland Larsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; tribology; friction; surface texture; surface design; low friction; high friction; boundary lubrication; DLC; embossing; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : This thesis comprises tribological studies of extremely well-defined surfaces of different designs. Both low-friction and high-friction surfaces were manufactured and experimentally evaluated.In the low-friction studies, lithography and anisotropic etching of silicon was first used as a texturing technique.

  3. 2. Microengineered CVD Diamond Surfaces : Tribology and Applications

    Författare :Joakim Andersson; Staffan Jacobson; Arto Alahelisten; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Diamond; DLC; Tribology; Friction; Environment; Microengineering; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Recent developments in thin film synthesis of diamond have facilitated a host of new technical applications. These are motivated by the many attractive properties of diamond, for example high hardness, chemical inertness, transparency and heat conductivity. Unfortunately, these properties also make it difficult to fashion complex geometries. LÄS MER

  4. 3. Genetic studies of neuroblastoma with emphasis on the apoptotic pathway

    Författare :Frida Abel; Göteborgs universitet; []
    Nyckelord :child; cancer; neuroectodermal; neural crest; loss of heterozygosity; LOH; bcl-2; mcl-1; apaf-1; caspase-2; caspase-3; caspase-9; PIN; DLC-1; caspase-2;

    Sammanfattning : Aim: The objective of this thesis was to find genes and chromosomal regions involved in neuroblastoma (NB) tumor progression. NB is a childhood tumor of the sympathetic nervous system that generally occurs spontaneously. LÄS MER

  5. 4. On the Formation of Low-Friction Tribofilms in Me-DLC – Steel Sliding Contacts

    Författare :Nils Stavlid; Urban Wiklund; Sture Hogmark; Erik Johansson; Uppsala universitet; []
    Nyckelord :Materials science; tribofilms; tribochemistry; boundary-lubrication; ESCA; Materialvetenskap;

    Sammanfattning : The present thesis thoroughly treats a special friction reduction phenomenon that may appear in boundary lubricated tribological contacts, of the type encountered in numerous mechanical components made of steel. The phenomenon involves the formation of a special type of tribofilm that offers very low coefficients of friction. LÄS MER

  7. 5. Benefits of Coordinating Plug-In Electric Vehicles in Electric Power Systems : Through Market Prices and Use-of-System Network Charges

    Författare :Ilan Momber; Lennart Söder; Tomás Gómez San Román; José Villar Collado; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicles; Power Systems; Optimization; Elektrische Voertuigen; Energiesystemen; Optimalisatie; Elbilarna; Elkraftsystem; Optimering; Vehiculos Electricos; Sistemas de Potencia; Optimización; Electrical Engineering; Elektro- och systemteknik; Economics; Nationalekonomi; Industriell ekonomi och organisation; Industrial Engineering and Management; Energy Technology; Energiteknik; Transportvetenskap; Transport Science;

    Sammanfattning : Both electric power systems and the transportation sector are essential constituents to modern life, enhancing social welfare, enabling economic prosperity and ultimately providing well-being to the people. However, to mitigate adverse climatological effects of emitting greenhouse gases, a rigorous de-carbonization of both industries has been set on the political agenda in many parts of the world.
