  2. 1. Characterizing ions in solution by NMR methods

    Author : Marianne Giesecke; István Furó; Peter Griffiths; KTH; []
    Keywords : electrophoretic NMR; diffusion NMR; NMR imaging; ion pairing; ion association; polyethylene oxide; metal-ion complex; Li ion batteries; electrolyte characterization; Kemi; Chemistry;

    Abstract : NMR experiments performed under the effect of electric fields, either continuous or pulsed, can provide quantitative parameters related to ion association and ion transport in solution.  Electrophoretic NMR (eNMR) is based on a diffusion pulse-sequence with electric fields applied in the form of pulses.

  4. 2. Solution-processed light-emitting electrochemical cells : challenges and opportunities

    Author : Etienne Auroux; Ludvig Edman; Christian Larsen; Andreas Sandström; Magnus Berggren; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Light-emitting electrochemical cell; PEDOT:PSS; Photonics; Ion transfer; Solution-based fabrication; Electronics; elektronik; Materials Science; materialvetenskap; jonfysik; Ion Physics;

    Abstract : Our world is filling up with electronics. High-tech gadgets are integrated everywhere, from smart fridges able to track expiry dates and food usage, to microchip implants that let us unlock doors and pay with our hands. READ MORE

  5. 3. Ions interacting with macromolecules : NMR studies in solution

    Author : Yuan Fang; Istvan Furo; Monika Schönhoff; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electrophoretic NMR; diffusion NMR; specific ion effects; Hofmeister; ion binding; Kemi; Chemistry;

    Abstract : Specific ion effects, identified for more than hundred years, play an important role in a wide range of phenomena and applications. Several mechanisms such as direct ion interaction with molecules have been suggested to explain these effects, but quantitative experimental evidence remains scarce. READ MORE

  6. 4. Classical and Car-Parrinello Molecular Dynamics Simulations of Polyvalent Metal Ions in Water

    Author : Sami Amira; Kersti Hermansson; Imre Bako; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Car-Parrinello molecular dynamics simulations; ab initio calculations; ion; copper; aluminium; metal ion; water; aqueous solution; solvation; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

    Abstract : The aqueous solvation of metal ions is one of the long-standing and complex problems in chemistry, with implications for and applications in a broad range of biochemical and electrochemical systems, where water is the all-pervasive medium.This thesis describes computer simulations of Al3+(aq), Fe2+(aq), Fe3+(aq) and Cu2+(aq).

  7. 5. Studies of individual pancreatic -cells : Electrophysiological analysis of rhythmic behaviour and development of new techniques

    Author : Staffan Dryselius; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic beta-cells; insulin release; signal transduction; cytoplasmic calcium; oscillations; patch clamp; ATP-regulated potassium channels; voltage-dependent calcium channels; metabolism; calcium ion; strontium ion; manganese ion; wavelets; de-noising; pattern recognition; superfusion; solution changes; microscopic labelling; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : The insulin concentration in blood varies periodically, which is believed to prevent down-regulation of the hormone receptors. Loss of the regular insulin oscillations is considered to be an early sign of developing diabetes. READ MORE
