  1. 6. Fluorine-Free Ionic Liquids and Electrolytes : From Synthesis to Energy Storage Applications

    Författare :Mukhtiar Ahmed; Faiz Ullah Shah; Patrik Johansson; Alexander Shaplov; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionic Liquids; Electrolytes; Sustainability; Lithium ion batteries; Flourine-Free; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Since their introduction by Sony in 1990, lithium-ion batteries (LIBs) have acquired a sizable market share. They have the best energy densities, a high open circuit voltage, a low self-discharge rate, no memory effect, and a slow loss of charge when not in use. LÄS MER

  3. 7. Ionic liquids in bio-refining : synthesis and applications

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

  4. 8. Lubrication mechanisms and properties of non-halogenated orthoborate ionic liquids

    Författare :Patrick Rohlmann; Sergei Glavatskih; Mark W. Rutland; Oleg N Antzutkin; Ali Erdemir; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic Liquids; Friction; Wear; Viscosity; Density; Additive; Machine Design; Maskinkonstruktion;

    Sammanfattning : One way to reduce energy consumption and waste - a necessity to achieve the UN-mandated limitation of average global temperature in-creases - is to select suitable lubricants so that energy-losses through friction and wear are minimised. In this context, non-halogenated ionicliquids (ILs) are promising candidates to achieve this aim due to their intrinsic ionic properties, low vapour pressure and high thermal stability. LÄS MER

  5. 9. Coarse-Grained Models of Ionic Solutions

    Författare :Ryan Szparaga; Beräkningskemi; []
    Nyckelord :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

  7. 10. Hybrid Solvents based on Ionic Liquids/Deep Eutectic Solvents for CO2 Separation : Experiments, Modeling, Process Simulation and Evaluation

    Författare :Chunyan Ma; Xiaoyan Ji; Päivi Mäki-Arvela; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 separation; Ionic liquids; Deep eutectic solvents; Cosolvent; Thermodynamic modeling; Process simulation and evaluation; Energiteknik; Energy Engineering;

    Sammanfattning : CO2 separation plays a vital role in reducing CO2 emissions to combat climate change, in which solvent-based absorption is widely considered the most promising technology. Many conventional chemical and physical solvents have been introduced for CO2 separation, still facing challenges. LÄS MER
