  1. 21. Conductive metal-organic frameworks (MOFs) and possible applications

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Meghdad Hosseinzadegan; [2022]
    Nyckelord :;

    Sammanfattning : Metal-organic frameworks (MOFs) are a class of hybrid organic/inorganic materials with permanent porous structure. Whilst there are virtually endless possible selection of metal ions and organic ligands to build up a MOF structure, intrinsically conductive MOFs are rare, relatively new, and our knowledge on their conductivity and charge transport mechanisms is limited.

  3. 22. Assessment of a Sustainable Water-based Lubricant for Electric Drivelines : Lubrication and Cooling performance of a Water-based Lubricant

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ugo Jantel; [2022]
    Nyckelord :Water-based Lubricant; Cooling; Driveline;

    Sammanfattning : In recent years, the impact of humans on the environment has been the subject of much debate. Car companies in particular are among the main actors in this environmental degradation with the polluting aspect of combustion cars. LÄS MER

  4. 23. Preparation and Experimental Investigation of the Tribological Properties of Conductive Grease Containing Ionic Liquids

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Gabriella Johansson Segervall; [2022]
    Nyckelord :Ionic liquids; bearing current; tribology; conductive grease;

    Sammanfattning : This thesis project was executed at ABB AB. The purpose of the thesis was to formulate aselection of ionic liquids with different thickeners as greases and experimentally understand thetribological characteristics and electrical properties. LÄS MER

  5. 24. Synthesis and thermoelectric properties of Cr1-xMexN (Me = Mo, V)

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Victor Rutberg; [2022]
    Nyckelord :Chromium nitride; thin films; thermoelectrics; physical vapour deposition; medium entropy alloy;

    Sammanfattning : Among emerging materials systems for thermoelectric applications, the early transition-metal nitrides based on ScN and CrN show unexpectedly promising properties. These properties are determined by high Seebeck coefficient, low thermal conductivity, and high electrical conductivity. LÄS MER

  7. 25. ADDITIVE MANUFACTURING OF PURE COPPER USING ELECTRON BEAM MELTING (EBM)

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Prithiv Kumar Chinnappan; Vishal Shanmugam; [2022]
    Nyckelord :Additive Manufacturing; Electron Beam Melting; Pure Copper; Process Optimisation.; Additiv tillverkning; Elektronstrålesmältning; Ren koppar; Processoptimering.;

    Sammanfattning : Pure copper (Cu) has the properties of high optical reflectivity and surface tarnishing as well as excellent thermal and electrical conductivity. Accordingly, laser-based additive manufacturing (AM) techniques confront various difficulties to produce thismaterial. LÄS MER
