    Sammanfattning : The following project has been carried out in collaboration with Abstracta AB (AAB), a company based in Lammhult with specialization in sound landscapes for indoor environments. The company manufactures different types of products with sound-absorbing properties where sustainability and design are in great focus. LÄS MER

  3. 17. 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.

  4. 18. Micro-architectured materials for thermal management : Porous graphite/graphene boiling enhancement structures

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

    Författare :Melody Ghaderidosst; [2022]
    Nyckelord :Microarchitecture; TPMS; Gyroid; thermo-mechanical; computational homogenization; graphite; graphene;

    Sammanfattning : The convergence of the digital and physical world encourages advances in high-speed telecommunication and fifth generation technology. Two-phase heat transfer systems are common engineering solutions. However, due to the large frequency spectra in 5G, the systematic heat generation increases requiring more efficient thermal management. LÄS MER

  5. 19. Double-layer vs single-layer cryogels as a dye affinity chromatography column, comparison study

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Thi Hoai Thu Trinh; [2022]
    Nyckelord :dye-affinity chromatography; single-layer cryogels; double-layer cryogels; protein purification; bovine serum albumin; biochemistry; Chemistry;

    Sammanfattning : Dye affinity chromatography is one of the chromatography techniques which uses dye as a ligand for protein purification. In this study, single-layer poly(acrylamide-allyl glycidyl ether) cryogel was prepared, which contains free epoxy groups at sub-zero temperature. LÄS MER

  7. 20. 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
