  1. 1. Ionic liquids The solid-liquid interface and surface forces

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Nicklas Hjalmarsson; KTH.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic liquids; solid-liquid interface; surface forces; nanotribology; atomic force microscopy; quartz crystal microbalance; Jonvätskor; gränsskiktet mellan fasta ytor och vätskor; ytkrafter; nanotribologi; atomkraftsmikroskopi; kvartskristallmikrovåg; Kemi; Chemistry;

    Abstract : Ionic liquids (ILs) present new approaches for controlling interactions at the solid-liquid interface. ILs are defined as liquids consisting of bulky and asymmetric ions, with a melting point below 373 K. Owing to their amphiphilic character they are powerful solvents but also possess other interesting properties. READ MORE

  2. 2. Flavins as Biomimetic Catalysts for Sulfoxidation by H2O2 Catalyst Immobilization in Ionic Liquid for H2O2 Oxidations

    University dissertation from Stockholm : Institutionen för organisk kemi

    Author : Auri Lindén; Stockholms universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomimetic; oxidation; catalysis; ionic liquid; hydrogen peroxide; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi;

    Abstract : This thesis deals with the development of catalytic oxidation reactions utilizing hydrogen peroxide as terminal oxidant. The main focus has been to find flavin catalysts that are easy to handle and stable to store but still able to perform the desired reaction. READ MORE

  3. 3. Ionic Liquid Electrolytes for Photoelectrochemical Solar Cells

    University dissertation from Stockholm : KTH

    Author : Heléne Gamstedt; KTH.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionic liquid electrolytes; Photoelectrochemical solar cells; NATURAL SCIENCES Chemistry Inorganic chemistry; NATURVETENSKAP Kemi Oorganisk kemi;

    Abstract : Potential electrolytes for dye-sensitized photoelectrochemical solar cells have been synthesized and their applicability has been investigated. Different experimental techniques were used in order to characterize the synthesized electrolytes, such as elemental analysis, electrospray ionisation/mass spectrometry, cyclic voltammetry, dynamic viscosity measurements, as well as impedance, Raman and NMR spectroscopy.

  4. 4. Ionic Liquid Based Electrolytes for High-Temperature Lithium-Ion Batteries

    University dissertation from Stockholm : KTH

    Author : Manfred Kerner; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMITFSI; EMIFSI; electrolyte; ionic liquid; lithium-ion battery; high-temperature stability; LiFSI;

    Abstract : Today, lithium-ion batteries (LIBs) are ubiquitous in mobile phones, laptops, and other portable devices. The research community strives to further improve the LIB to increase electric driving distance and efficiency of both hybrid electric vehicles (HEVs) and fully electric vehicles (EVs). READ MORE

  5. 5. Ionic liquids in bio-refining synthesis and applications

    University dissertation from Umeå : Umeå universitet

    Author : John Gräsvik; Umeå universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionic liquid; Joniska vätskor;

    Abstract : Fossil fuel resources are not limitless so alternative renewable recourses are needed to fill the void that inevitably will be created once the supplies of this resource start do dwindle. Biomass has the potential to fill this void. READ MORE
