  1. 1. Exploring alternative surfactants to replace PEG within lipid nanoparticles

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master); Lunds universitet/Bioteknik (CI); Lunds universitet/Bioteknik (master)

    Författare :Elina Edidovica; [2024]
    Nyckelord :Lipid nanoparticle; polyethelyne glycol PEG ; alpha-tomatine; N-hexadecyl beta d-maltoside HDM ; DOPC; DPPC; cholesterol; film hydration; stability study; DLS; Cryo-TEM; SAXS; pharmaceutical formulation; Chemistry;

    Sammanfattning : Over the past decade an increasing amount of studies has demonstrated that PEGylation not only precipitates reductions in drug delivery efficiency but also triggers the immune system to produce antibodies, specifically anti-PEG antibodies. The objective of my thesis is to explore alternative surfactants that could viably replace PEG within lipid nanoparticles. LÄS MER

  3. 2. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Aidas Urbonavicius; [2023]
    Nyckelord :ETEM; Nucleation; GaSb; Nanowires; Materials chemistry; Technology and Engineering; Chemistry;

    Sammanfattning : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. LÄS MER

  4. 3. EV battery temperature estimation : Designing a model for minimal temperature of high-voltage battery in a BEV

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Författare :Björn Arvidsson; [2023]
    Nyckelord :BEV; temperature estimation; lowpass filter; BEV; lågpassfilter; temperaturestimering;

    Sammanfattning : Fordonsindustrin är inne i ett skifte, där förbränningsmotorer (ICE) bör-jar fasas ut och det satsas mer på eldrift med hjälp av batterier (BEV).  I detta arbete, som efterfrågades av Volvo Cars, utvecklades en matema-tisk modell som uppskattar den lägsta temperaturen i en elbils högspän-ningsbatteri.

  5. 4. The Commissioning of a Pixelated Charge-particle Detector : for High-sensitivity Measurements of Hydrogen

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Joacim Stenlund; Aram Himelius; [2023]
    Nyckelord :;

    Sammanfattning : The Tandem Laboratory at Uppsala University, a national research infrastructure forworld-leading materials analysis, has a long history of performing hydrogen measurementusing NRA (Nuclear Reaction Analysis). This project intents to diversify the infras-tructure for hydrogen measurement by investigating the feasibility of an advanced ERCS(Elastic Recoil Coincidence Scattering) system, enabling finer detection limits.

  7. 5. Design and implementation of an affordable reversing camera system with object detection and OBD-2 integration for commercial vehicles

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Alireza Ebrahimi; Esmatullah Akbari; [2023]
    Nyckelord :Reversing camera system; object detection; OBD-2-integration; ultrasonic sensors; accident risk; driver assistance.; Backkamerasystem; objektdetektering; OBD-2-integration; ultraljudssensorer; olycksrisk; förarassistans.;

    Sammanfattning : This thesis is about designing and implementing an affordable reversing camera sys-tem with object detection and OBD-2 integration for commercial vehicles. The aim is to improve the safety and efficiency of these vehicles by giving drivers a clear view of their surroundings behind the vehicle and alerting them to the presence of nearby obstacles. LÄS MER
