  2. 1. Making Radical Cations Live Longer

    Author : Ola Persson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spin trapping.; 3-hexafluoropropan-2-ol; 3; 1; thallium III -based oxidants; Radical cations; electron paramagnetic resonance; Physics; Fysik; Chemistry; Kemi;

    Abstract : The acid-catalyzed rearrangement of 1,4,5,8-tetramethylnaphthalene was used to determine the acidity of media used for EPR spectral studies of radical cations. The radical cations of methyl-substituted naphthalenes were shown to undergo dimerization reactions. READ MORE

  4. 2. Charge transport modulation in organic electronic diodes

    Author : Fredrik Lars Emil Jakobsson; Magnus Berggren; Xavier Crispin; Paul W. M. Blom; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; switch device; memory; photochromic; trapping; resistance switching; Physics; Fysik;

    Abstract : Since the discovery of conducting polymers three decades ago the field of organic electronics has evolved rapidly. Organic light emitting diodes have already reached the consumer market, while organic solar cells and transistors are rapidly maturing. One of the great benefits with this class of materials is that they can be processed from solution. READ MORE

  5. 3. Spin and charge in low-dimensional semiconductors

    Author : Peter Jaksch; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis we investigate the trapping of spin-polarized electrons in edge states around a pair of antidots (Paper I). This study supports a proposal for using the trapped electrons to realize quantum gates - the building blocks of a quantum computer. READ MORE

  6. 4. Proton trapping in the cellular acidic vacuolar compartment : lysosomal mechanisms in apoptosis/necrosis and iron chelation

    Author : Zhengquan Yu; Anders Isaksson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Under ischemic conditions, a number of cytotoxic metabolic products are formed. Reactive oxygen species are known to be important mediators of progressive ischemic cell injury, and the synergistic damage to cells caused by the combination of such oxygen species and redox-active iron is well appreciated.

  7. 5. Structural, Electronic and Reactive Properties of Pentapyridyl - Base Metal Complexes : Relevance for Water Oxidation Catalysis

    Author : Manuel Boniolo; Johannes Messinger; Antoni Llobet; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water oxidation; Base metal complexes; Redox potential; Spin crossover; Magnetic anisotropy; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

    Abstract : The rationalization of chemical-physical proprieties of transition metal complexes is fundamental in order to understand and tune their reactivity. In this thesis, a systematic investigation of the geometrical and electronic properties of [M(Py5OH)Cl]+ complexes (M= Mn, Fe, Co, Ni) has been performed, and their ability to act as molecular water oxidation catalysts has been probed.
