  4. 2. Atomic decomposition of molecular properties

    Author : Ignat Harczuk; Hans Ågren; Olav Vahtras; Per-Olof Åstrand; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : In this thesis, new methodology of computing properties aimed for multipleapplications is developed. We use quantum mechanics to compute propertiesof molecules, and having these properties as a basis, we set up equations basedon a classical reasoning. READ MORE

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

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

    Abstract : 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.
