  1. 16. Polymeric single Li+-ion conductors: preparation and characterisation

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Hannes Nederstedt; [2016]
    Nyckelord :single ion conductors; electrolytes; polymers; lithium ion batteries; polymer technology; polymerteknologi; Chemistry; Technology and Engineering;

    Sammanfattning : Lithium-ion batteries are a common type of light-weight, rechargeable batteries. There are safety concerns because these batteries typically use an organic solvent electrolyte which presents fire hazards. By using dry polymer electrolytes, the fire hazards can be eliminated.

  3. 17. Time-resolved study of charge photo-generation in polymer-based solar cells with low driving force

    Magister-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Paulius Baronas; [2014]
    Nyckelord :Organic polymer solar cells; BHJ solar cells; Charge photo-generation; Driving force; Time resolved photoluminescence; CT states; Physics and Astronomy;

    Sammanfattning : Organic polymer-based solar cells recently attracted much attention as an efficient and inexpensive light-to-electricity conversion solution. However, the mechanism behind charge generation processes in organic materials is still not fully understood due to complex nature of carbon-based compounds. LÄS MER

  4. 18. Dynamisk skjuvreometer och kompletterande metoder för bitumenundersökningar

    Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

    Författare :Khalid Kamil; Henrik Jakobsson; [2014]
    Nyckelord :dsr; dynamisk skjuvreometer; bitumen; sasobit; polymermodifierat; mscr; kryptest; reologi; superpave; Technology and Engineering;

    Sammanfattning : Increasing heavy traffic on the roads raises demands on pavements and especially the binder of the pavements. The rutting and other deformations resistances are constantly improved. As a part of the development wax mixes and polymer modified variants are produced. LÄS MER

  5. 19. Some aspects of ionic liquid blends and additives influencing bulk conductivity of commercial base paper

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

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

    Sammanfattning : 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.
