  1. 6. Ion association to poly(N-isopropylacrylamide) by diffusion and electrophoretic NMR

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Cedrik Wiberg von Schantz; [2013]
    Nyckelord :PNIPAM; poly N-isopropylacrylamide ; electrophoretic NMR; diffusion NMR; LCST; ion association;

    Sammanfattning : PNIPAM (poly(N-Isopropylacrylamide)) is a well-known thermoresponsive polymer. Dissolved in water, it shows a structural change at 32 oC, above which the polymer folds together, and a phase separation occurs. LÄS MER

  3. 7. Investigation of crown ether cation systems using electrophoretic NMR

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Fredrik Petersson; [2012]
    Nyckelord :electrophoretic NMR; diffusion NMR; crown ether; electrophoretic mobility and equilibrium constant;

    Sammanfattning : The purpose of this thesis was to investigate how crown ethers behave and interact with different cations and to optimise the setup of the electrophoretic NMR. To get a good electrophoretic NMR measurement the electrophoretic phase shift needs to be big. LÄS MER

  4. 8. NMR detection of liquid dynamics in porous matrices

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Payam Pourmand; [2012]
    Nyckelord :Porous material; Controlled Pore Glass; NMR; Diffusion NMR;

    Sammanfattning : Porous materials or a porous media can be encountered in our everyday life, both in industrial and household systems and in the nature. Generally speaking all solid and semisolid materials are porous to some degree e.g. different dense rock types, plastics etc. LÄS MER

    Master-uppsats, KTH/Tillämpad fysikalisk kemi

    Författare :Payam Pourmand; [2012]
    Nyckelord :Porous material; Controlled Pore Glass; NMR; Diffusion NMR;

    Sammanfattning : Porous materials or a porous media can be encountered in our everyday life, both in industrial and household systems and in the nature. Generally speaking all solid and semisolid materials are porous to some degree e.g. different dense rock types, plastics etc. LÄS MER

  7. 10. How ionic are ionic liquids?

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Kristoffer Bernhem; [2011]
    Nyckelord :Ionic liquid; ion charge; association; electrophoretic NMR; diffusion NMR.;

    Sammanfattning : Ionic liquids are continuously finding more and more applications, both in research and in the industry. Many attempts have been made to find parameters that could be used to describe all ionic liquid systems. Five years ago a Japanese group applied the work of Gutmann on ionic liquids to use ionic association to describe solvation effects. LÄS MER
