  2. 1. An Infrared Study of Intermolecular Interactions in Gaseous Hydrogen Bonded Molecular Complexes

    Author : René Wugt Larsen; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intermolecular potential energy surface; Physical chemistry; Fysikalisk kemi; synchrotron radiation; infrared absorption spectroscopy; intermolecular vibration; molecular complex; Intermolecular interactions; hydrogen bond;

    Abstract : Intermolecular interactions are responsible for the deviations of gases from ideality, determine the three- dimensional structure and folding dynamics of biological molecules, and the binding of molecules to surfaces as in heterogeneous catalysis. The hydrogen bond is the most important intermolecular interaction. READ MORE

  4. 2. Surface-Induced Modification of Supported Late Transition Metal Complexes

    Author : Olesia Snezhkova; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene palladium complexes; X-ray photoelectron spectroscopy; electron charge transfer; iron phthalocyanine; catalysis; X-ray absorption spectroscopy;

    Abstract : The work presented in this thesis addresses the investigation of the electronic, magnetic, and structural properties of late transition metal complexes supported on various surfaces. The research is aimed at studying the interaction between the molecules and the support, together with the intermolecular interaction. This knowledge is essential e.g. READ MORE

  5. 3. Singlet Fission - The Effects of Solvent Polarity and Conformation

    Author : Rasmus Ringström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Singlet fission; rotational conformation; photoinduced electron transfer; transient absorption;

    Abstract : Singlet fission (SF) is a process in which one initial high energy singlet excited state is converted into two triplet excited states of roughly half the energy of the initial state. This process has the potential to increase the efficiency of conventional solar cells by modifying the energy of the incident solar radiation to better match the energy input required to generate electricity.

  6. 4. Scanning probe microscopy studies of interaction forces between particles: emphasis on magnetite, bentonite and silica

    Author : Illia Dobryden; Neil Thomson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Abstract : Scanning probe microscopy (SPM), such as the atomic force microscope (AFM), using colloidal probes is a highly suitable technique to probe single particle-particle interactions in aqueous solution. The interaction force between a colloidal probe on the AFM cantilever and sample surface is measured. READ MORE

  7. 5. Water at surfaces and interfaces from first-principles studies

    Author : Sheng Meng; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Water is ubiquitous in nature and ordinary to us. However, no matter how common it is, water is unique, mysterious, and has numerous unusual properties, many of which still lack a scientific interpretation. READ MORE
