  1. 1. En teoretisk modell för 3D-printing av fälg i kolfiber

    M1-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Samuel Hall; [2022]
    Nyckelord :3D-printing; Carbon fiber; Carrim; Automotive wheels;

    Sammanfattning : The automotive industry faces the challenge to manufacture vehicles with reduced material usage and climate impact. To achieve this the industry has begun using other materials such as carbon fibre composite than materials such as steel and aluminium which are normally used for the manufacturing of automobile parts.

  2. 2. Mapping of Material & Conversion Parameters of Packaging Production – Boardio®

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Yusuf Qasem; Younes Chraibi Ottosson; [2022]
    Nyckelord :Chemical Engineering; Packaging; Packaging Production; Paperboard; Converting; Lamination; Extrusion; Die-cutting; X-ray tomography; GPI; Creasing; Perforation; Tensile Strength; Technology and Engineering;

    Sammanfattning : With an increased demand for sustainable packaging solutions for the ever-growing FMCG market, fiber-based systems rise as an answer to phasing out plastics in packages and reducing the humanity’s climate footprint. However, constructing a packaging solution largely consisting of paperboard comes with its challenges, such as integrating functionalities in the anisotropic paperboard that formerly were provided by a fundamentally different materials with divergent mechanical properties, being isotropic polymers.

  3. 3. The Effect of Process Parameters on Columnar-To-Equiaxed-Transition (CET) During Electron Beam-Powder Bed Fusion of Ferritic Stainless Steel

    Master-uppsats, KTH/Materialvetenskap

    Författare :Doom Eleanor Ihensekhien; [2022]
    Nyckelord :Additive manufacturing; E-PBM; Inoculation; process parameters; TiN; CET;

    Sammanfattning : Electron Beam Powder Bed Fusion manufacturing of components is an additive manufacturing process that is complex and has widespread advantages for aerospace and many industrial processes. It reduces costs and has a larger powder particle size requirement. LÄS MER

  4. 4. High-performance implementation of H(div)-conforming elements for incompressible flows

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Niklas Wik; [2022]
    Nyckelord :Finite elements; H div -conforming; incompressible flows; incompressible Navier-Stokes equations; high-performance; matrix-free; Raviart-Thomas;

    Sammanfattning : In this thesis, evaluation of H(div)-conforming finite elements is implemented in a high-performance setting and used to solve the incompressible Navier-Stokes equation, obtaining an exactly point-wise divergence-free velocity field. In particular, the anisotropic Raviart-Thomas tensor-product polynomial space is considered, where the finite element operators are evaluated with quadrature in a matrix-free fashion using sum-factorization on tensor-product meshes.

  5. 5. An Initial Exploration of Transition Metal Nitroprussides as Electrode Materials for Sodium-ion Batteries

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Veronica Enblom; [2022]
    Nyckelord :Sodium-ion batteries; Transition metal nitroprussides; Electrode materials; Prussian blue analogues; Cathode materials; Nitrosyl redox; Anisotropic charge transfer; Hysteresis; Sustainable batteries;

    Sammanfattning : Na-ion batteries (NIBs) are expected to revolutionise the battery sector by promising an affordable technology while capitalising on sustainable development. To compete with Li-ion batteries, however, electrode materials with higher capacities need to be developed. LÄS MER
