  2. 2. Gear tribology : friction and surface topography

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

    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

  3. 3. 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

  4. 4. Electron and Spin Transport in Graphene-Based Nanodevices

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

  5. 5. Studies of Hydrogenations and Isomerizations of Olefins and Alkylations of Amines Using Iridium Catalysts

    Author : Jia-Qi Li; Pher Andersson; Jianliang Xiao; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Iridium; Asymmetric; Hydrogenation; Isomerization; Alkylation; Organisk kemi; Organic Chemistry;

    Abstract : This thesis describes three types of reactions that were carried out using iridium catalysts.The first type is the iridium-catalyzed asymmetric hydrogenation of olefins. In paper I, the preparation of a new type of bicyclic thiazole-phosphine based iridium complex was described. READ MORE
