  1. 26. 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

  3. 27. Physical measurements and subjective characterization of pipe organ mechanical key actions

    Författare :Erkin Asutay; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical key action; Pipe organ; Instrument – player interaction;

    Sammanfattning : Musical instruments do not only provide auditory or visual information but they also convey haptic feedback to the performer. One might consider that the auditory feedback is the only crucial information that the musician requires. LÄS MER

  4. 28. Remote Measurements of Gas and Particulate Matter Emissions from Individual Ships

    Författare :Jörg Beecken; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollution; compliance monitoring; shipping; ship emission; particle emissions; identification of polluting ships; emission factors;

    Sammanfattning : Shipping significantly contributes to the world's anthropogenic emissions of sulfur, nitrogen species and particulate matter. These species affect the global radiative forcing as well as local acidification, eutrophication and human health. LÄS MER

  5. 29. Turbulence Measurements in a Natural Convection Boundary Layer and a Swirling Jet

    Författare :Abolfazl Shiri; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swirl; constant current bridge; high Rayleigh number; natural convection; Jet; cold-wire thermometry; vertical cylinder; laser Doppler anemometry; turbulent boundary layers;

    Sammanfattning : Two sets of experimental measurement were carried out on an axisymmetric swirling jet flow and a natural convection boundary layer. In the first experiment, the far field of an incompressible swirling jet, discharged into a quiescent ambient has been studied using laser Doppler anemometry. LÄS MER

  7. 30. Hygroscopic Properties of Atmospheric Aerosol Particles in Various Environments

    Författare :Jingchuan Zhou; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tandem differential mobility analyser TDMA ; internal and external mixture; closure study; GDF95; AOE-96; Fysik; Physics; Kärnfysik; Nuclear physics; ACE-2; CLAIRE98; differential mobility particle sizer DMPS ; atmospheric aerosol particles; hygroscopic growth; Fysicumarkivet A:2001:Zhou;

    Sammanfattning : Atmospheric aerosol particles affect our living environment in many ways. Their effects are influenced by the interaction between the aerosol particles and the ubiquitous water vapour. The number-size distribution is a primary important parameter for aerosol particles and can be measured using the differential mobility particle sizer (DMPS). LÄS MER
