    Sammanfattning : Given the potential of ionic liquids (ILs) for batteries, supercapacitors and advanced lubricants, it is crucial to understand how electric fields affect the interfacial behaviour in IL-solvent systems and the intricate relationship between nanostructure and tribotronic properties. This thesis investigates the structural and compositional changes of ILs with different solvents at electrified interfaces. LÄS MER

  3. 2. Capacitive Mixing for Extracting Concentration Gradient Energy

    Författare :Zhi Zou; Longcheng Liu; Chia-Hung Hou; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacitive mixing; salinity gradient energy; salt difference energy; electric double layer; flow electrode CapMix; kapacitiv blandning; salthaltsgradientenergi; saltskillnadsenergi; elektriskt dubbelskikt; flödeselektrod CapMix.; Chemical Engineering; Kemiteknik;

    Sammanfattning : Capacitive mixing (CapMix) is a renewable method of extracting energy from the salinity gradient energy (SGE) between seawater and freshwater. The classical CapMix systems using solid electrodes generate electricity by periodically circulating seawater and freshwater into the CapMix system. LÄS MER

  4. 3. Concentrated DNA-amphiphiles Structure, Hydration, and Dynamics

    Författare :Cecilia Leal; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amphiphiles; DNA; Physical chemistry; diffusion NMR; solid-state NMR; electrostatics; dynamics; local order; Fysikalisk kemi; hydration;

    Sammanfattning : The structure, hydration, and dynamics of concentrated DNA-amphiphile complexes were investigated by small-angle X-ray diffraction, sorption calorimetry, and nuclear magnetic resonance. A concentrated, electroneutral, DNA-amphiphile complex can be formed by mixing charge-stoichiometric solutions. LÄS MER
