  1. 1. Surface treatment methods for metal components trays and frames

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Josu Najera Bernabeu; Alaitz Egaña Azkargorta; [2023]
    Nyckelord :;

    Sammanfattning : The proper selection of materials and surface treatment is critical in ensuring the strength, durability, and safety of metal structures in various environments. Therefore, this project is being developed in collaboration with Aurobay Company to explore and provide insights into the most suitable material and surface treatment method for a frame. LÄS MER

  3. 2. Investigation of flux dependence on viscosity in ultrafiltration

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Peter Bourghardt; [2023]
    Nyckelord :ultrafiltration; viscosity; molasess; konjac glucomannan; comsol; LabStak M39; membrane; filtration; chemical engineering; Chemistry;

    Sammanfattning : This project aims to compare the effect of viscosity on flux for high viscosity liquids. The performance of two different viscous solutions was studied in a plate-and-frame membrane module. LÄS MER

  4. 3. Tuning electrolyte-electrode interphases for low-temperature Li-ion batteries

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Robin Xu; [2023]
    Nyckelord :Li-ion batteries; Low temperature;

    Sammanfattning : Lithium ion batteries (LIBs) are crucial for modern electronics and electric vehicles (EV). However,their electrochemical performance is facing challenges at low temperatures (e.g ≤ 0 °C) due to reducedLi+ kinetics and increased charge-transfer resistance. LÄS MER

  5. 4. Exploring Particulate Filtration during Thermal Runaway in Lithium-Ion Battery Packs

    Master-uppsats, KTH/Kemiteknik

    Författare :Amanda Halvarsson; [2023]
    Nyckelord :battery pack; particles; thermal runaway; filtration; batteripack; partiklar; termisk rusning; filtrering;

    Sammanfattning : Med övergången till elektrifiering inom transport uppstår nya utmaningar när det gäller batterisystem som placeras i elfordon. Det finns för närvarande en möjlighet att minska riskerna med toxiciteten hos partiklar som sprutas ut med de gaser som bildas under termisk rusning i litiumjonbattericeller som är placerade i batterisystem.

  7. 5. Detection of Vancomycin-resistant Enterococci, an evaluation of direct analyzing from ESwab using real-time PCR detection kit and culture

    Kandidat-uppsats, Uppsala universitet/Klinisk mikrobiologi

    Författare :Therése Röjås; [2023]
    Nyckelord :VRE; Viasure; BD MAX System; enrichment broth; Chromogenic agar;

    Sammanfattning : Background: Vancomycin-resistant enterococci (VRE) is a common nosocomial infection. It classifies as Enterococcus faecalis or faecium carrying vanA or vanB gene that alters the bacterial cell wall hence lowering affinity for Vancomycin. LÄS MER
