  1. 21. Some aspects of ionic liquid blends and additives influencing bulk conductivity of commercial base paper

    University essay from Karlstads universitet/Avdelningen för kemiteknik

    Author : Salman Javaid; [2013]
    Keywords : ionic liquids; ion conductive paper; 1-butyl-3-methylimidazolium tetrafluoroborate; 1-butyl-3-methylimidazolium hexafluorophosphate; conducting polymer;

    Abstract : In this study, bulk conductivity of commercial base paper impregnated with different ionic liquids blends and additives, through bench coating was investigated. Bulk conductivity of base paper, ion conductive paper and surface sized ion conductive papers with and without the influence of calendering were evaluated at different concentrations of ionic liquids using at resistivity cell and four point probe technique.

  4. 23. Design and performance analysis of purely textile antenna for                                                   wireless applications

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Robi Dahal; Demet Mercan; [2012]
    Keywords : Textile antenna; RFID;

    Abstract : This thesis work is concerned with the design and performance analysis of purely textile antenna for wireless applications. The materials used for radiating element, ground plane and dielectric substrate are purely textile. Two types of antennas are studied, the microstrip patch antenna and RFID tag antenna. READ MORE

  5. 24. A practical assessment of frequency electromagnetic inversion in a near surface geological environment

    University essay from Lunds universitet/Geologiska institutionen

    Author : Mattias Letellier; [2012]
    Keywords : frequency; electromagnetic; sounding; inversion; GEM-2 frekvens; elektromagnetiska; sondering; GEM-2; Earth and Environmental Sciences;

    Abstract : Under de senaste 15 åren har användningen av frekvenselektromagnetiska sonderingsinstrument inom geofysiska undersökningar drivit forskningen framåt för att förbättra den använda metoden. En av dessa tekniker är inversion vilket är den process som omvandlar elektromagnetiska data till djupvärden för geologiska lager. READ MORE

  6. 25. Impact on Soil and Groundwater from Road Maintenance and Traffic: Initial Study of the E18 Highway.

    University essay from KTH/Mark- och vattenteknik

    Author : Robert Earon; [2011]
    Keywords : Geophysics; Resistivity; Hydrogeology; Contaminant Transport; Contaminant Distribution; Soil and Water Chemistry;

    Abstract : The investigation of environmental impacts of 16 different contaminants originating from the E18 Highway (17 000 AADT) were carried out over the first six months of the highway‘s operational life. Investigative methods used include electrical resistivity surveying, water chemistry analyses, soil analyses, distribution modelling and transportation modelling. READ MORE
