  1. 1. Electronic properties of organic molecular materials

    Författare :Mikael Unge; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In the context of molecular based electronics, different molecular systems have been studied. In molecular crystals of pentacene, the conduction process has been reported to occur in a single layer in field-effect transistor applications. LÄS MER

  2. 2. Molecular Electronics : A Theoretical Study of Electronic Structure of Bulk and Interfaces

    Sammanfattning : This thesis deals with theoretical studies of the electronic structure of molecules used in the context of molecular electronics. Both studies with model Hamiltonians and first principle calculations have been performed. LÄS MER

  3. 3. The Chorda Tympani Nerve : Role in Taste Impairment in Middle Ear Disease and after Ear Surgery

    Författare :Katarina Berling Holm; Magnus von Unge; Mikael Karlberg; Uppsala universitet; []
    Nyckelord :Chorda tympani nerve; ear surgery; taste; chronic suppurative otitis media; otosclerosis; electrogustometry; filter paper disc method; quality of life; transmission electron microscopy; degeneration; sprouting; Surgery; Kirurgi;

    Sammanfattning : The chorda tympani nerve, also known as the taste nerve, runs uncovered through the middle ear cavity, a localization that exposes the nerve to pathological processes and surgical trauma in the middle ear. People operated on for otosclerosis tend to complain more about postoperative taste disturbances than those operated on for chronic otitis media. LÄS MER

  4. 4. Ab initio modelling of interfaces in nanocomposites for high voltage insulation

    Författare :Elena Kubyshkina; B. Lars G. Jonsson; Mikael Unge; Per-Olof Åstrand; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Sammanfattning : Dielectric nanocomposite materials have been experimentally proven to have properties that are beneficial in applications for efficient energy transport. However, today there are still no empirical models or rules that can predict the performance of a certain combination of materials in the nanocomposite, and there are also no definitive explanations of their dielectric behavior.
