1. 11. CO2 separation using ionic liquid-based absorbents : thermodynamics and kinetics

   Författare :Yifeng Chen; Xiaoyan Ji; Xiaohua Lu; Marcus Öhman; Congmin Wang; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic liquids; carbon dioxide; thermodynamics; kinetics; Energiteknik; Energy Engineering;

   Sammanfattning : Ionic liquids (ILs) have shown great potential to be used as absorbents for CO2 separation owing to their unique properties such as immeasurably low vapour pressure, high thermal stability, high CO2 affinity, and tunable structure. A huge amount of researches have been carried out, and most of them focused on developing novel ILs for CO2 separation. LÄS MER

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface active ionic liquids; protic ionic liquids; nanoconfinement; oriented and parallel nanochannels;

   Sammanfattning : Long-chain ionic liquids are attracting interest as alternatives to their short-chain analogues as electrolytes. At the same time, they are also considered as alternatives to mesogens and conventional surfactants as templates. LÄS MER

4. 13. Electrospinning Nanofibres from Cellulose Dissolved in Ionic Liquid

   Författare :Linda Härdelin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dissolution; Electrospinning; molecular weight distribution.; cellulose; rheology; ionic liquids; nanofibres;

   Sammanfattning : This thesis investigates the electrospinning of cellulose nanofibres from ionic liquids. Cellulose nanofibres produced by an environmentally friendly process have the potential to replace synthetic nanofibres produced with volatile and harmful solvents. LÄS MER

5. 14. Electro-Interfacial Composition Control by Ionic Liquid Technology : Nanostructure, Self-Assembly, and Friction

   Författare :Sichao Li; Mark W. Rutland; Sergei Glavatskih; Nicholas Spencer; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionic liquids; electrical double layer; self-assembly; electro-interfacial structure; tribotronics; supercapacitors; friction; lubrication; Jonvätskor; elektriskt dubbelskikt; självassociering; gränsskiktselektrostruktur; tribotronik; superkondensatorer; friktion; smörjning; Kemi; Chemistry;

   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

7. 15. Ionic Liquid Lubricants for Space Applications

   Författare :Erik Nyberg; Ichiro Minami; Javier Martin-Torres; Maria-Dolores Bermudez; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

   Sammanfattning : Lubrication is critical to the efficient and reliable operation of machine elements such as gears, bearings, or any other moving mechanical assembly (MMA). On Earth, machine designers are accustomed to the access of a wide range of liquid lubricants that enable predictable and reliable long-term operations of high performance MMA. LÄS MER
