    Master-uppsats, KTH/Fysik

    Författare :Maria Giamouridou; [2023]
    Nyckelord :uranium nitride nuclear fuel; advanced nuclear fuel; uranium nitride fabrication; uranium nitride characterisation; Spark Plasma Sintering; proton irradiation; irradiation damage; TANDEM accelerator; irradiation induced cracking; irradiation induced hardening; irradiation induced swelling; hydrogen implantation; dislocation loops; kärnbränsle av urannitrid; avancerat kärnbränsle; tillverkning av urannitrid; karakterisering av urannitrid; Spark Plasma Sintering; protonbestrålning; strålningsskador; TANDEM-accelerator; strålningsinducerad sprickbildning; strålningsinducerad härdning; strålningsinducerad svällning; väteimplantation; dislokationsloopar;

    Sammanfattning : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. LÄS MER

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

    Master-uppsats, KTH/Tillämpad fysik

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

    Sammanfattning : 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. LÄS MER

  4. 3. Determination of the inelastic mean freepath for SiO2 and the BBL polymer : A study with XPS and HAXPES

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Rickard Gauffin; [2022]
    Nyckelord :XPS; HAXPES; IMFP; Polymer;

    Sammanfattning : This study targets methodology development using Photoelectron Spectroscopy (PES) as a tool for investigating material surfaces. When analysing samples with X-ray Photoelectron Spectroscopy (XPS) and Hard X-ray Photoelectron Spectroscopy (HAXPES), it is important to know the probing depth of the samples. LÄS MER

  5. 4. Analysis of Stiffness Measurement Methods on Extracellular Vesicles

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Hanna Kylhammar; [2022]
    Nyckelord :Extracellular Vesicles; AFM; Atomic Force Microscopy; Fluorescent Microscopy; Extracellulära Vesiklar; AFM; Atomkraftsmikroskopi; Fluorescensmikroskopi;

    Sammanfattning : Extracellular vesicles are important players in cell-to-cell communication and have the potential to be used as biomarkers for decease. The mechanical properties of extracellular vesicles is an active field of research, with new methods and models being developed. LÄS MER

  7. 5. Corrosion protection of aluminum coated with a polymer matrix in presence and absence of conductive polymer

    Master-uppsats, KTH/Ytbehandlingsteknik

    Författare :Mohamed Hassan Abdi; [2021]
    Nyckelord :Corrosion protection; Barrier coating; Conductive polymer; Electrochemical impedance spectroscopy; Atomic force microscopy; Korrosionsskydd; Barriär beläggning; Ledande polymer; Elektrokemisk impedans spektroskopi; Atomkraftmikroskopi;

    Sammanfattning : Aluminium och aluminiumlegeringar har ganska bra korrosionsbeständighet, men dessa material kan fortfarande korrodera. Metallkorrosion är aldrig önskvärt och det kan leda till katastrofala resultat i olika branscher och applikationer. LÄS MER
