  2. 21. Interaction Between Microgels and Oppositely Charged Peptides

    Author : Helena Bysell; Martin Malmsten; Per Hansson; Walter Richtering; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; binding; cationic peptides; confocal microscopy; deswelling; distribution; electrostatic; homopolypeptides; microgels; peptides; release; swelling; PHARMACY; FARMACI; Pharmaceutical Physical Chemistry; farmaceutisk fysikalisk kemi;

    Abstract : Lightly cross-linked polyelectrolyte microgels are materials with interesting properties for a range of applications. For instance, the volume of these particles can be drastically changed in response to pH, ionic strength, temperature, or the concentration of specific ions and metabolites. READ MORE

  4. 22. 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.

  5. 23. Electron - Ion Recombination Data for Plasma Applications : Results from Electron Beam Ion Trap and Ion Storage Ring

    Author : Safdar Ali; Reinhold Schuch; José R. Crespo López-Urrutia; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Highly charged ions; Atomic processes; Atomic data; Electron-ion recombination; Plasmas; fysik; Physics;

    Abstract : This thesis contains results of electron-ion recombination processes in atomic ions relevant for plasma applications. The measurements were performed at the Stockholm Refrigerated Electron Beam Ion Trap (R-EBIT) and at the CRYRING heavy-ion storage ring. READ MORE

  6. 24. Atomic Spectroscopy for Applications in Energy Technology

    Author : Thomas Lennartsson; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atomic structure; plasma diagnostics; branching fractions; gas discharges; highly charged ions; extreme ultraviolet spectra; time-resolved spectroscopy;

    Abstract : This thesis intends to provide spectroscopic information which may be of use in the investigation of low-density plasmas. Developed since the 19th century, the spectroscopic approach has proven to be a versatile method for measuring properties in hot gases, such as electron and ion temperatures and densities, the abundance of various elements in the gas, etc. READ MORE

  7. 25. SMILETRAP I / II : Precision Improvements in Penning-Trap Mass-Spectrometry

    Author : Markus Suhonen Linné; Reinhold Schuch; Lutz Schweikhard; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Penning trap; Mass spectrometers; Instrumentation and methods for time-of-flight TOF spectroscopy; Highly charged ions; Atomic physics; Atomfysik; fysik; Physics;

    Abstract : This thesis describes the final precision mass measurements with SMILETRAP I, where a relative precision of < 1 ppb (10-9) was reached routinely, and the development of SMILETRAP II, aiming for measurements with < 0.1 ppb relative precision. READ MORE
