  1. 1. Surfaces Designed for High and Low Friction

    University dissertation from Uppsala : Institutionen för teknikvetenskaper

    Author : Ulrika Pettersson; Uppsala universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; tribology; friction; surface texture; surface design; low friction; high friction; boundary lubrication; DLC; embossing; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : 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.

  2. 2. Microengineered CVD Diamond Surfaces Tribology and Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Joakim Andersson; Uppsala universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Diamond; DLC; Tribology; Friction; Environment; Microengineering; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : 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. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Frida Abel; Göteborgs universitet.; Gothenburg University.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; child; cancer; neuroectodermal; neural crest; loss of heterozygosity; LOH; bcl-2; mcl-1; apaf-1; caspase-2; caspase-3; caspase-9; PIN; DLC-1;

    Abstract : 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. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Nils Stavlid; Uppsala universitet.; [2006]
    Keywords : Materials science; tribofilms; tribochemistry; boundary-lubrication; ESCA; Materialvetenskap;

    Abstract : 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. READ MORE

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

    University dissertation from Madrid, Spain : Camillas Pontifical University

    Author : Ilan Momber; KTH.; [2015]
    Keywords : 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; Nationalekonomi; Economics; Industriell ekonomi och organisation; Industrial Engineering and Management; Energiteknik; Energy Technology; Transportvetenskap; Transport Science;

    Abstract : 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.
