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

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

    Abstract : 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. READ MORE

  7. 5. Two-dimensional Nanocomposites Based on Cellulose Nanofibrils and Graphene Oxide

    Abstract : Two-dimensional (2D) nanocomposites based on cellulose nanofibrils (CNF) and 2D nanomaterials are of interest as sustainable materials combining functional and structural properties. To achieve reinforcement effects from 2D nanomaterials, their orientation and dispersion state in the CNF matrix are important. READ MORE
