  2. 11. Electro-Interfacial Composition Control by Ionic Liquid Technology : Nanostructure, Self-Assembly, and Friction

    Author : Sichao Li; Mark W. Rutland; Sergei Glavatskih; Nicholas Spencer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionic liquids; electrical double layer; self-assembly; electro-interfacial structure; tribotronics; supercapacitors; friction; lubrication; Jonvätskor; elektriskt dubbelskikt; självassociering; gränsskiktselektrostruktur; tribotronik; superkondensatorer; friktion; smörjning; Kemi; Chemistry;

    Abstract : Given the potential of ionic liquids (ILs) for batteries, supercapacitors and advanced lubricants, it is crucial to understand how electric fields affect the interfacial behaviour in IL-solvent systems and the intricate relationship between nanostructure and tribotronic properties. This thesis investigates the structural and compositional changes of ILs with different solvents at electrified interfaces. READ MORE

  4. 12. Friction and Wear Mechanisms of Ceramic Surfaces : With Applications to Micro Motors and Hip Joint Replacements

    Author : Johanna Olofsson; Staffan Jacobson; Håkan Engqvist; Koshi Adachi; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; Friction; Wear; Ceramic; Tribofilm; Alumina; Silicon nitride; Ultrasonic Motors; Hip Joint Replacement; PVD coating; Materials science; Teknisk materialvetenskap; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Surfaces exposed to wear always transform and typically a layer of new structure and composition is formed. This layer, often called tribofilm, changes the friction and wear properties. READ MORE

  5. 13. On interface modeling  with emphasis on friction

    Author : Anders Söderberg; Sören Andersson; Lars-Erik Stacke; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interface model; contact; friction; simulation; system behaviour; surface roughness; elastic foundation; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : The general trend toward increased use of computer models and simulations during product development has led to a need for accurate and reliable product models. The function of many products relies on contact interfaces between interacting components. READ MORE

  6. 14. Flow and Friction : On the Tactical Potential of Interfacing with Glitch Art

    Author : Vendela Grundell; Anna Dahlgren; Mårten Snickare; Max Liljefors; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Glitch; Contemporary Art; Photography; Digital Media; Interface; Internet; Systems Aesthetics; Network Society; Tactics; Phenomenology; Spectatorship; Viewer; Experience; Rosa Menkman; Phillip Stearns; Evan Meaney; konstvetenskap; Art History;

    Abstract : This thesis aims to analyze how interfacing affects viewer experiences and viewer positions, and how glitch art online makes that effect visible. Glitch art is concerned with disruptions in the systems that govern how for instance photography is produced, circulated and displayed in a digital image flow. READ MORE

  7. 15. Studies of Nanowire Friction using AFM-based Manipulation

    Author : Gabriela Conache; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanomanipulation; AFM; Nanowires; Nanotribology; Friction; Nanotechnology.;

    Abstract : In this thesis we present friction studies on InAs nanowires pushed laterally across surfaces by an AFM tip. The contact length in the direction of movement is of the order of a few tens of nanometers, and is thus comparable to that found in existing point-contact studies, but perpendicular to the motion the wire can be several microns in length.
