  1. 11. Sensing capability of nanomodified Portland cement composites

    Författare :Thanyarat Buasiri; Andrzej Cwirzen; Karin Habermehl-Cwirzen; Jan Olek; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensing cementitious composites; nanomodified Portland cement; Carbon nanofibers; CNF; piezoresistive materials; sensor; cement-based sensor; self-monitoring; sensing capability; Byggmaterial; Building Materials;

    Sammanfattning : Sensing cement-based composites refer to composites that have sensing functionality that can measure several physical and chemical parameters. Sensing cement-based composites are fabricated by incorporating some functional fillers, such as conductive fibers (CFs), carbon nanofibers (CNFs), carbon nanotubes (CNTs), and graphene, into conventional concrete.

  3. 12. A Quantum Chemical View of Molecular and Nano-Electronics

    Författare :Jun Jiang; Yi Luo; Jim Greer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi;

    Sammanfattning : This dissertation presents a generalized quantum chemical approach for electron transport in molecular electronic devices based on Green's function scattering theory. It allows to describe both elastic and inelastic electron transport processes at first principles levels of theory, and to treat devices with metal electrodes either chemically or physically bonded to the molecules on equal footing.

    Författare :Paata Kakashvili; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conformal field theory; Coulomb blockade; Wigner crystal.; Strongly correlated electrons; Kondo effect; bosonization; Luttinger liquid; STM; single-electron transistor;

    Sammanfattning : In this Ph.D. thesis I present the background and providefurther details to the work presented in the appended papers. The background consists of brief overviews of Kondo physics, Luttinger liquid theory, and conformal field theory. LÄS MER

  5. 14. Strongly Interacting Electrons in One and Two Dimensions

    Författare :Fabrizio Anfuso; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis I present a theoretical study of three differentstrongly correlated systems: Luttinger liquids, spin-1 chains andthe two-dimensional spin-1/2 Heisenberg model.For every sub-field of our research I summarize the background andprovide further details to the work presented in the appendedpapers.

  7. 15. Sputtered Carbon Nitride Thin Films

    Författare :Niklas Hellgren; Bernd Schultrich; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The relation between the growth conditions and the film structure and properties of reactively magnetron sputtered carbon nitride CNx (0 ≤ x ≤ 0.6) thin films has been studied. The growth of CNx films has been studied when varying the process parameters, such as substrate temperature, N2 (partial) pressure and ion flux. LÄS MER
