    Författare :Nicklas Hjalmarsson; Mark W Rutland; Rob Atkin; Enrico Gnecco; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; NATURAL SCIENCES; 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;

    Sammanfattning : 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. LÄS MER

  2. 2. Ionic liquids in bio-refining : synthesis and applications

    Författare :John Gräsvik; Jyri-Pekka Mikkola; Bertil Eliasson; Manu Lahtinen; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Ionic liquid; Joniska vätskor;

    Sammanfattning : 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. LÄS MER

  3. 3. Coarse-Grained Models of Ionic Solutions

    Författare :Ryan Szparaga; Teoretisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; Classical Density Functional Theory; Coarse-Grained Models; Ionic Liquids; Prewetting; Capillary Condensation; Electric Double Layer; Differential Capacitance.;

    Sammanfattning : Room-temperature ionic liquids (RTILs) are compounds composed entirely of ions, which are liquid at temperatures below 100 degrees Celsius. Their high ionic strength and strong coupling make them useful for a number of applications, e.g. as electrolytes in supercapacitors. LÄS MER

  4. 4. Proton conducting ionic liquids-Binary mixtures and structural modifications

    Författare :Iqbaal Abdurrokhman; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanostructure; hydrogen bonds; Protic ionic liquids; fuel cell;

    Sammanfattning : Proton conduction is a phenomenon of fundamental importance for biological and chemical systems, such as in photosynthesis and aerobic respiration. Proton conduction is also key in the proton exchange membrane fuel cell, a clean electrochemical device that converts chemical into electrical energy. LÄS MER
