  4. 2. Overcoming the Mass Transport Limitations of Dye-Sensitised Solar Cells : Towards highly efficient and robust alternative redox mediator electrolyte DSSCs

    Author : Roger Jiang; Gerrit Boschloo; Erik Johansson; Anders Hagfeldt; Frédéric Sauvage; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dye-sensitised solar cell; dye-sensitized solar cell; photoelectrochemical cell; cobalt tris bipyridine ; mass transport; photocurrent transients;

    Abstract : Dye-sensitised solar cells (DSSCs) have been subject to decadelong research interest, and may have some potential niche market applications. Recently, major advances in power conversion efficiencies have been achieved following the transition to cobalt polypyridine based redox mediators. READ MORE

  5. 3. Friction in highly pressurized lubricants and its relation to thermo-physical properties

    Author : Bert-Olof Åhrström; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The objective of this work was to increase the understanding of which lubricant properties control transient friction, and during what environmental conditions friction is minimized. The experiments have been conducted during conditions relevant to an elastohydrodynamic contact, with pressures extending up to 2. READ MORE

  6. 4. Mathematical Analysis of Forced Convective Flow Due to Stretching Sheet and Instabilities of Natural Convective Flow

    Author : Prashant G Metri; Sergei Silvestrov; Rebei Bel-Fdhila; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Boundary layer theory; Heat and Mass transfer; Partial differential equations; Stretching sheet; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : The investigations presented in the thesis are theoretical studies of magnetohydrodynamic flows, heat and mass transfer in Newtonian/non-Newtonian cooling liquids, due to horizontal/vertical stretching sheet. The theoretical studies include the effect of magnetic field, uniform and non-uniform heat source/sink (flow and temperature dependent heat source/sink) effects. READ MORE

  7. 5. Boundary integral methods for fast and accurate simulation of droplets in two-dimensional Stokes flow

    Author : Sara Pålsson; Anna-Karin Tornberg; Shravan Veerapaneni; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

    Abstract : Accurate simulation of viscous fluid flows with deforming droplets creates a number of challenges. This thesis identifies these principal challenges and develops a numerical methodology to overcome them. Two-dimensional viscosity-dominated fluid flows are exclusively considered in this work.
