  1. 11. Comparison and optimization of extracellular vesicle (EV) capturing on functional thin films for their molecular profiling

    University essay from KTH/Tillämpad fysik

    Author : Prattakorn Metem; [2023]
    Keywords : extracellular vesicle; plasmonic nanohole array; atomic force microscopy; fluorescence analysis; extracellulära vesiklar; nanohålsuppsättning; atomkraftsmikroskopi; fluorescensanalys;

    Abstract : Extracellular vesicles (EVs) are lipid bilayer encapsulated nanoparticles which have emerged as an excellent source of biomarkers for multiple diseases, including cancer. However, they are highly heterogeneous in their molecular compositions which remains a major challenge hindering the utilization of their biomarker potential. READ MORE

  3. 12. The Influence of Roughness on Electrical Properties of Single Rock Fractures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

  5. 14. Thermal Investigation of the Green Revolution Energy Converter : A study on the heat transfer within the GREC in regards of temperature distribution and heat rate

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Wilma Fager; Maja Abrahamsson Bolstad; Emma Gustafsson; Emma Andersson; Matilda Eriksson; [2023]
    Keywords : GREC; Energy; Heat transfer; Heat rate; Temperature distribution;

    Abstract : To reduce emissions, new technological solutions can be of use. One technology which is currently being developed is the Green Revolution Energy Converter, GREC. GREC is an engine with the aim to produce electricity from temperature gradients.  This project is part of a greater project that is divided in two with different focus areas. READ MORE

  6. 15. Simulation of the Filling of Epoxy in Resin Impregnated Paper Bushings : Analysis of Temperature Measurements during Filling of Epoxy and the Generation of New Filling Recipes to Avoid Cavities in the RIP Bushing

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Hanna Damsgaard Falck; [2023]
    Keywords : Porous media; COMSOL Multiphysicis; Darcy s Law; Richard s Equation; Resin Impregnated Paper Bushings; RIP Bushings; Bushings; Transformers; Epoxy; Simulation;

    Abstract : The goal of the project was to create a model in COMSOL Multiphysics that can simulate thefilling of resin (epoxy) in Resin Impregnated Paper (RIP) bushings. Using the model new fillingrecipes that avoid problematic double-fronts and thereby avoid the creation of cavities in thebushings should be designed. READ MORE
