  1. 1. Process parameter optimisation for Waspaloy using Laser-Directed Energy Deposition with Powder

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Johannes Lövhall; [2024]
    Nyckelord :Process parameter optimisation; Waspaloy; Laser-Directed Energy Deposition with Powder;

    Sammanfattning : Material utilisation is of importance in the manufacturing industry formaking the most of each material, minimising waste and increasing cost-effectiveness. In this thesis, samples of Waspaloy built with the method of L-DED-P has been analysed in order to investigate how process pa-rameters influence the build quality and geometrical accuracy in as-builtobjects.

  3. 2. Comparison of properties on Orally Disintegrating Tablets (ODTs) produced by direct compression or fluid bed granulation

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Julia Ahlbom; [2023]
    Nyckelord :Orally disintegrating tablet; fluid bed granulation; disintegration time; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : Orally disintegrating tablets (ODTs) is a popular drug delivery system as they dissolve in the mouth, usually within seconds which enables easy medication for patients with problem swallowing. In this thesis properties of ODTs were compared when produced with direct compression of the excipients or the excipients were pretreated to form granules in a fluid bed granulator prior to tableting.

  4. 3. The effect of high pressure homogenization on emulsions containing oat β-glucan : a study of viscosity, stability and molecular weight

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Dominika Kiesling; [2023]
    Nyckelord :oat; β-glucan; high pressure homogenization; emulsion; stability; food technology; Agriculture and Food Sciences;

    Sammanfattning : This master thesis project has been conducted in cooperation with Lantmännen AB who are producers of PromOat® - an oat β-glucan powder concentrate. The main objective of this thesis was to investigate the properties of emulsions containing PromOat® oat β-glucan, focusing on the viscosity, stability, and molecular weight before and after high pressure homogenization (HPH) at pressures of 100, 150 and 200 bars.

  5. 4. Lösning för användning av schampokoncentrat

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

    Författare :Hala Mawas; Carl Jonas Wiklander; [2023]
    Nyckelord :;

    Sammanfattning : Följande projekt var ett kandidatexamensarbete i Teknisk Design vid Kungliga Tekniska Högskolan i Stockholm. Syftet med projektet var att utveckla en lösning som tillåter en smidig och attraktiv användning av ett schampokoncentrat. Koncentratet utvecklades av start-up företaget Hair-Ability och bestod av ett pulver. LÄS MER

  7. 5. Magnetic properties of a martensitic stainless steel powder : Investigation of magnetic properties for a metallic powder with different sizes and its possible correlation to flow properties

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Carl Back; Saga Grevarp; Arthur Pollet; [2023]
    Nyckelord :;

    Sammanfattning : For metal powders, flow properties are important. If the powder does not move properly, it can result in problems with the final product in additive manufacturing. Some of the products created with this manufacturing method are complex and used for important purposes such as medical devices and aerospace. LÄS MER
