  2. 1. Controlled axonal outgrowth and cell reactions to nanostructures

    Author : Fredrik Johansson; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Contact guidance; neuron; axon; fibroblast; macrophage; polymethylmethacrylate; porous silicon; nanowire; magnetic; immunoresponse; nanoimprint lithography; haptotaxis;

    Abstract : The interface between living cells and artificial surfaces are highly relevant for biomedical applications such as implants and organized cell growth for tissue reconstruction as well as for basic science purposes. In the present thesis, we have studied axonal guidance on various nano-patterned surfaces such as polymethyl-meth-acrylate, porous silicon and on magnetically aligned Ni nanowires. READ MORE

  4. 2. On Simulation of Uniform Wear and Profile Evolution in the Wheel - Rail Contact

    Author : Roger Enblom; Mats Berg; Simon Iwnicki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; wear; wear prediction; wear model; wheel profile; rail; Vehicle engineering; Farkostteknik;

    Abstract : Numerical procedures for reliable wheel and rail wear prediction are rare. Recent development of simulation techniques and computer power together with tribological knowledge do however suggest computer aided wear prediction as possible. READ MORE

  5. 3. A TEM Investigation of Contact between Nanoparticles

    Author : Yiming Yao; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LACBED; CBED; nanoparticles; interface; adhesion; image simulation; energy filtering; misorientation; contacting; strain field TEM;

    Abstract : Interaction between nanoparticles (1~100nm) provides us with answers to fundamental questions in many important applications e.g. adhesion, friction, and cold welding. The attractive force arises from the reduction of the total free surface and thus the total surface energy due to the formation of a boundary between the contacting particles. READ MORE

  6. 4. Towards the enhanced applicability of cold mix asphalt: : An experimental study focusing on surface free energies and the breaking and coalescence of bitumen emulsions

    Author : Abdullah Khan; Nicole Kringos; Per Redelius; Andreas Loizos; KTH; []
    Keywords : Bitumen; Cold Asphalt Mixtures; Minerals Aggregates; Surface Free Energy; Sorption; Contact Angle; Bitumen Emulsions; Breaking and Coalescence; Emulsifiers; Adhesion Promoters.; Bitumen; kallblandad asfalt; mineraler aggregat; fri ytenergi; sorption; kontaktvinkel; Bitumenemulsioner; brytning och koalescensen; emulgatorer; adhesionsegenskaper; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : The environmental, social and economic sustainability of our infrastructure network is clearly of paramount importance to the road-engineering sector as well to society at large. Sustainable road materials and reduced transport of those materials therefore play a significant role. READ MORE

  7. 5. Optimization-based robot grasp synthesis and motion control

    Author : Robert Krug; Achim Lilienthal; Dimitar Dimitrov; Sami Haddadin; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Robot grasping; grasp synthesis; grasp planning; motion control; model predictive control; independent contact regions; obstacle avoidance; motion planning; Datavetenskap; Computer Science;

    Abstract : This thesis investigates the questions of where to grasp and how to grasp a given object with an articulated robotic grasping device. To this end, aspects of grasp synthesis and hand motion planning and control are investigated. READ MORE
