  1. 1. Tuning physical and chemical attributes of the synthetic implant poly(L-lactic acid) and its effects on biological stimulation

    Kandidat-uppsats,

    Författare :Gabriella Sverlinger; Felicia Norman; Nora Othman; Wilma Hämäläinen; Michaela Thyberg; Maja Jonsson; [2023]
    Nyckelord :Polylactic acid; degradation rate of PLLA; physio- chemical properties of PLA; injectable PLLA;

    Sammanfattning : Poly(lactic acid) (PLA) is a polymer chain consisting of repeating units of lactic acid (LA) used in various biomedical applications because of its biocompatible features. It is commonly used as a subdermal filler and constitutes as the main ingredient in SculptraR, which is a collagen regenerating filler used to treat lipoatrophy of the cheeks or to rejuvenate the skin.

  2. 2. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

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

    Författare :Nipon Roy; [2023]
    Nyckelord :Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Sammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER

  3. 3. Evaluation of Woodmer/plastic composites

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Leon Ahlström; [2023]
    Nyckelord :Extrusion; Woodmer; Flame test; Tensile test; Composites; Extrudering; Woodmer; Flamtest; Dragtest; Kompositer;

    Sammanfattning : Plast ger otroliga möjligheter i form av stor variation för materialanvändning. Tyvärr sker det dock på bekostnad av miljön då de ackumuleras i naturen. En kompromiss mellan hållbarhet och fortsatt plastanvändning skulle kunna vara att använda biomassa som fyllnadsmaterial i plastkompositer istället för plast. LÄS MER

  4. 4. Individanpassade hjälpmedel framtagna med additiv tillverkning

    M1-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Albin Ylönen; Lovisa Anderssson; [2023]
    Nyckelord :;

    Sammanfattning : In this project, both an existing product has been further developed and a new project has been created from scratch. These two products are designed to facilitate the daily life of wheelchair users. LÄS MER
