  4. 2. Gear tribology : friction and surface topography

    Author : Li Xiao; Bengt-Göran Rosén; Liam Blunt; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; Surface topography; Toughness; Lay; Gears; Power transmission; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The quest for energy efficiency leads to the development of highly efficient power transmissions for vehicles. Gears are some of the most rugged and durable torque transmitters among machine elements. Friction between sliding surfaces at gear teeth is one major source of power loss. READ MORE

  5. 3. Toward Energy-efficient Physical Vapor Deposition : Routes for Replacing Substrate Heating during Magnetron Sputtering by Employing Metal Ion Irradiation

    Author : Xiao Li; Grzegorz Greczynski; Ivan Petrov; Lars Hultman; Jyh-Wei Lee; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PVD; Magnetron sputtering; Thin films; HiPIMS; TiAlN; Energy efficiency;

    Abstract : In this Thesis, magnetron sputtering is perfected as an environmental-friendly deposition technique. I performed systematic studies of a novel approach - hybrid high-power impulse and dc magnetron co-sputtering (HiPIMS/DCMS) with metal-ion-synchronized substrate bias pulses. READ MORE

  6. 4. Nephrin cellular trafficking and intracellular interactions

    Author : Xiao Li Liu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Nephrin; signal; missense mutations; trafficking.;

    Abstract : Nephrin is a 180-kDa transmembrane glycoprotein belonging to the immunoglobulin family of cell adhesion molecules. Nephrin has an extracellular part with eight Ig-like motifs, one fibronectin-like domain, a transmembrane region and a short cytoplasmic tail. READ MORE

  7. 5. Electron and Spin Transport in Graphene-Based Nanodevices

    Author : Xiao-Fei LI; Yi Luo; Rajeev Ahuja; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SRA - Transport; SRA - Transport;

    Abstract : This thesis is devoted to the multi-scale modeling of electron and spin transport in graphene-based nanodevices. Several devices with fascinating structures and attractive properties have been designed by means of state-of-the-art computational methods, which include ab-initio molecular dynamics (MD) simulations for the geometry, density functional theory (DFT) for the electronic structure, and non-equilibrium Green’s functions (NEGF) for carriers transport properties.
