   Sammanfattning : Aqueous solutions were studied using photoelectron and Auger spectroscopy, based on synchrotron radiation and a liquid micro-jet setup. By varying the photon energy in photoelectron spectra, we depth profiled an aqueous tetrabutylammonium iodide (TBAI) solution. LÄS MER

3. 22. Multiscale simulations of soft matter: systematic structure-based coarse-graining approach

   Författare :Alexander Mirzoev; Alexander Lyubartsev; Nico van der Vegt; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiscale modeling; Monte Carlo; Molecular dynamics; ion solution; lipid bilayer; coarse-graining; fysikalisk kemi; Physical Chemistry;

   Sammanfattning : The soft matter field considers a wide class of objects such as liquids, polymers, gels, colloids, liquid crystals and biological macromolecules, which have complex internal structure and conformational flexibility leading to phenomena and properties having multiple spacial and time scales. Existing computer simulation methods are able to cover these scales, but with different resolutions, and ability to link them together performing a multiscale simulation is highly desirable. LÄS MER

4. 23. Characterising Weak Interactions in Solution. : An NMR Spectroscopic Approach

   Författare :Scott Wilcox; Máté Erdélyi; Chris Hunter; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

   Sammanfattning : Detecting and characterising weak interactions in dilute solutions is challenging. This thesis focusses on the development of a new NMR spectroscopic strategy to do so, whilst also investigates a newly proposed type of weak interaction in solution with currently available NMR techniques.

5. 24. Lithium Ion Conductive Membranes Based on Co-continuous Polymer Blends

   Författare :Anette Munch Elmér; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; Polymer technology; biopolymers; conductivity measurements; in-situ UV-polymerisation; solution casting; poly methyl methacrylate ; vinylidene fluoride copolymers; poly ethylene carbonate-co-ethylene oxide methacrylate; PEG methacrylate macromonomers; heterogeneous polymer blends; polymer electrolyte membranes; lithium salt containing gels;

   Sammanfattning : There is a growing need for multifunctional polymeric materials for the development of several important energy conversion technologies. For example, the polymer electrolyte is a key component in lithium polymer batteries. The basic functions of this electrolyte are to efficiently conduct the lithium ions and physically separate the electrodes. LÄS MER
