  1. 1. Exosomal Shuttle RNA

    Författare :Karin Ekström; Göteborgs universitet; []
    Nyckelord :exosomes; exosomal; shuttle; RNA; esRNA; vesicles; mast cell; gene transfer; microRNA;

    Sammanfattning : Exosomes are small membrane nanovesicles of endocytic origin that can be released by many different cells to the extracellular environment. Exosomes have been found in a number of body fluids such as blood plasma, breast milk, bronchoalveolar lavage fluid and urine, indicating relevance in vivo. LÄS MER

  3. 2. Multiscale Modelling of a Nanoelectromechanical Shuttle

    Författare :Caroline Huldt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DFT; Nanoelectromechanics; Mesoscopics; Shuttle; Multiscale;

    Sammanfattning : Nanoelectromechanical systems couple mechanical and electronic degrees of freedom creating a new type of electrical components. The nanoelectromechanical shuttle consists of a double junction with a movable central island. LÄS MER

  4. 3. Electromechanical Interactions in Shuttle Systems and Carbon Nanotube Relays

    Författare :Tomas Nord; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coulomb blockade; carbon nanotubes; memory device; nanorelay; single electron tunneling; van der Waals forces; NEMS; shuttle transport; mesoscopic; nanoelectromechanical systems;

    Sammanfattning : In this thesis we theoretically investigate two kinds of nanoscale systems where there is a strong electromechanical coupling, i.e. an intricate relation between the Coulomb forces that can appear in these systems and the displacements of parts of the systems that they cause.

  5. 4. Modelling of Molecular-Scale Nanoelectromechanical Systems

    Författare :Caroline Huldt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; shuttle; mesoscopic; NEMS; graphene; multiscale; DFTB; DFT;

    Sammanfattning : Nanoelectromechanical systems (NEMS) couple electronic and mechanical degrees of freedom in a nanoscopic structure. The small size introduces many atomistic and quantum mechanical features which on the one hand open up for interesting new features and possibilities but on the other hand make it very difficult to formulate quantitative predictions.

  7. 5. Mechanisms of charge transfer in dissipative shuttle nanostructures

    Författare :Tomas Nord; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;
