  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. 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

  3. 3. Coarse-Grained Models of Ionic Solutions

    University dissertation from Division of Theoretical Chemistry, Department of Chemistry, Lund University

    Author : Ryan Szparaga; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; Classical Density Functional Theory; Coarse-Grained Models; Ionic Liquids; Prewetting; Capillary Condensation; Electric Double Layer; Differential Capacitance.;

    Abstract : Popular Abstract in English Typically, when we speak of ionic solutions we mean a salt (as solute) dissolved in some liquid (the solvent). In this thesis, we predominantly consider ionic solutions for which there is no solvent---room-temperature ionic liquids (RTILs). READ MORE

  4. 4. Cellulose processing in ionic liquid based solvents

    University dissertation from Division of Theoretical Chemistry, Department of Chemistry, Lund University

    Author : Carina Olsson; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; esterification; cellulose; NMR spectroscopy; solution spinning; dissolution; ionic liquids; cellulose derivatives; rheology; crystallinity;

    Abstract : As the most abundant polymer in nature, cellulose has an undisputed role among the raw materials to be used in a sustainable future. From its native form, in wood or straw, cellulose can be processed into products such as paper and board. READ MORE

  5. 5. Orthoborate Ionic Liquids for Lubricated Interfaces

    University dissertation from Luleå tekniska universitet

    Author : Mamoun Taher; Luleå tekniska universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials science - Functional materials; Chemistry - Physical chemistry; Chemistry - Organic chemistry; Materials science - Surface engineering; Teknisk materialvetenskap - Funktionella material; Kemi - Fysikalisk kemi; Kemi - Organisk kemi; Teknisk materialvetenskap - Ytbehandlingsteknik; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : The lifespan and efficiency of various types of machinery is often limited by the performance of its lubricated interfaces, which are formed by two interacting surfaces and a lubricant that separates the surfaces to decrease friction and wear. There is a constant quest for more efficient lubricants capable of lubricating non-ferrous surfaces. READ MORE
