  2. 1. Graphene as Solid Lubricant in Polymer Composites : With Application in Hydropower Bearings

    Author : Julian Somberg; Nazanin Emami; Jan Ukonsaari; Gil Gonçalves; Sergei Glavatskih; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Solid Lubricant; Polymer Composite; Friction; Hydropower; Machine Elements; Maskinelement;

    Abstract : With a rising global demand for green energy production, hydropower plays a key role in securing a reliable and sustainable energy supply. Hydropower is the largest and most efficient renewable energy source, with an ever-increasing capacity. READ MORE

  4. 2. Computer Modelling of the Interaction between Water and Complex Solid Phases

    Author : Susanne Börjesson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SOLISOL; thermodynamic model; complex solid; cement; PHREEQE; repository; PASSIPHIC; leaching; solid solution;

    Abstract : In this work the program package PASSIPHIC is described. The program has been developed to calculate the equilibrium for an aqueous phase in contact with a complex solid. The complex solid is considered as consisting of pure minerals and /or solid solutions. Cement has been used as an example. READ MORE

  5. 3. Modelling elements in conversion of solid fuels - fixed bed combustion and gaseous radiation

    Author : Robert Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; fixed bed; modelling; solid fuels; gas radiation;

    Abstract : For a long heat and power production by combustion of solid fuels has time been an established technique. Environmental concern of emissions for NOx, SOx and other harmful species has caused an increasingly stricter legislation on the emission levels of the boilers. READ MORE

  6. 4. Hyperfine investigations on solid compounds of transition elements

    Author : Roger Wäppling; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : .... READ MORE

  7. 5. Electronic transitions and correlation effects : From pure elements to complex materials

    Author : Johan Jönsson; Igor A. Abrikosov; Marcus Ekholm; Sergei Dudarev; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electronic transition; solid state physics; condensed matter physics; correlation effects;

    Abstract : Macroscopic properties of real materials, such as conductivity, magneticproperties, crystal structure parameters, etc. are closely related or evendetermined by the configuration of their electrons, characterized by electronicstructure. By changing the conditions, e.g, pressure, temperature, magnetic/electric field, chemical doping, etc. READ MORE
