  1. 21. In-plane Wetting in Packaging Material and its Consequences for Cap Performance

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Ellinor Carolina Salomonsson; [2023]
    Keywords : Tetra Pak®; Aseptic; Paperboard; Pre-laminated hole; Edge wicking; In-plane wetting; Hydrogen peroxide; Cap detachment; Polymer technology; Technology and Engineering;

    Abstract : Aseptic packaging solutions enable long time storage without refrigeration and are an important part of securing food supply globally. The package material consists of multiple layers: A paperboard for robustness, polymers for adhesion as well as shielding the board from liquid, and a barrier protecting the product. READ MORE

  3. 22. Experimental Study of Magnetic Field Effects on Hairpin SNSPD Turn Designs for Single Photon Detection : Investigating the Relationship between Magnetic Field Strength and SNSPD Performance

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : James Arthur Sutton; [2023]
    Keywords : SNSPD; Hairpin device; Magnetic field effect; Current crowding; SNSPD; Hårnålsanordning; Magnetfältseffekt; Nuvarande trängsel;

    Abstract : Superconducting Nanowire Single Photon Detectors (SNSPDs) are a promising technology for detecting single photon emissions with high efficiency and low noise. This detector class has numerous applications in quantum optics, communication, and sensing. READ MORE

  4. 23. Investigation of charge injection at electrode-dielectric interface relevant for HVDC cables : Simulation of charge injection and transport dynamics in electrical insulation for HVDC cables

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Mohammed Mosa; [2023]
    Keywords : BCT model; charge injection; space charge density; electric field distribution; Fowler-Nordheim; Richardson-Schottky;

    Abstract : A bipolar charge transport (BCT) model is used to simulate charge injection and transportdynamics inside insulation material which are used in a high voltage direct current (HVDC)cable. Gaining knowledge about space charge density and electric field distribution in theinsulation material enables minimising charge injection at the metal-insulator interface andavoiding unnecessary energy loss.

  5. 24. Use of Pulse Thermography for Characterization of Defects in Polymer Composites

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

    Author : Kim Klöckner; [2023]
    Keywords : NDT; Pulse Thermography; polymer composites; boats manufacturing; end-of-life structures; defect characterization;

    Abstract : In this project, the possibility of using thermography as a non-destructive testing tool in the manufacturing process of boats and to assess the quality of end-of-life composite structures has been explored. To do so, a literature surview regarding the current applications of thermography and the techniques currently used for quality control in the boats industry has been conducted. READ MORE

  6. 25. Study of surfactant-preservative and protein-preservative interactions in multi-dose injectable formulation

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Javier Lagares Martín; [2023]
    Keywords : Phenol; polysorbate 80; cloud point; somatropin; aggregation; titration; light scattering; salt; surfactant; preservative; protein; tonicity adjusting agents; multi-dose injectable formulation; pharmaceutical technology; Technology and Engineering;

    Abstract : Multidose injectable formulations require a preservative such as phenol to ensure sterility and protection against microbial contamination during clinical use. However, it is known that the interaction between these components and non-ionic surfactants such as polysorbate 80, also found in this type of formulations, present incompatibilities, which can lead to decreases in the efficacy of the product.
