  1. 1. Sustainable food packaging based on polyhydroxyalkanoate

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Safana Al-Ashor; [2024]
    Keywords : Biopolymers; Sustainable food packaging; Circular economy; Biobased and biodegradable materials; Food packaging; Processing technologies; Food quality; Shelf-life;

    Abstract : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. READ MORE

  3. 2. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

    University essay from KTH/Fiber- och polymerteknologi

    Author : Felix Bogdan; [2023]
    Keywords : Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

    Abstract : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. READ MORE

  4. 3. Performance Evaluation of a 3D Printed Mirror Actuator : A Comparison with the James Webb Space Telescope

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Louise Leopoldsson; Ellen Lindsjö; [2023]
    Keywords : Actuator; James Webb Space Telescope;

    Abstract : This study aims to investigate the similarities in precision and performance between a James WebbSpace Telescope mirror actuator, the part controlling the motion of the primary mirror segments,and two 3D printed replicas. The two replicas were made from the plastics PLA and PETGand based on the designs of Zachary Tong. READ MORE

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

    University essay from

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

    Abstract : 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.

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

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Abstract : 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. READ MORE
