  2. 21. Spectroscopic and elastic properties in metallic systems from first-principles methods

    Author : Christian Asker; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : In this thesis, ab initio calculations on metallic systems are presented. The overall aim is to probe properties that are often considered to be difficult to obtain within the framework of density-functional theory. The aim has also been to chose problems and systems that are of a wider interest and not only a testbed for calculations. READ MORE

  4. 22. Electronic and structural properties of nanoclusters

    Author : Alexey Tal; Igor Abrikosov; Peter Münger; Weine Olovsson; Alessandro De Vita; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nanoclusters have gained a huge interest due to their unique properties. They represent an intermediate state between an atom and a solid, which manifests itself in their atomic configurations and electronic structure. READ MORE

  5. 23. Optical Modeling and Characterization of Layers and Multilayer Structures : Organic Optoelectronic Devices and Spectroscopic Ellipsometry

    Author : Leif A. A. Pettersson; Robert W. Collins; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This dissertation is on the subject of modeling and characterization of layers and multilayer structures with respect to their optical properties and characteristics. A number of different systems have been investigated; among them multilayer structures in the form of organic optoelectronic devices, anisotropic layers of conjugated polymers as well as inhomogeneous layers of porous silicon and oxidized silver.

  6. 24. Shining Light on Benzothiadiazoles and Indolines : Photophysical Properties and Cancer Cell Imaging

    Author : Susanne Doloczki; Christine Dyrager; Andrey Klymchenko; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Fluorescent molecules, also called fluorophores, play an important role in life sciences. As crucial tools in fluorescence microscopy, they can be used to study biological processes on a cellular level, which is a fundamental aspect of cancer research. READ MORE

  7. 25. Fundamental Properties of Functional Magnetic Materials

    Author : Magnus Wikberg; Peter Svedlindh; Per Nordblad; Klas Gunnarsson; Amílcar Labarta; Uppsala universitet; []
