    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. Damage Analysis of Reactive Ion and Atomic Layer Etched Silicon

    Magister-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Mohammad Al Abrash; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Dry etching is one of the most important methods of pattern transfer in nanofabrication. There are many dry etching methods, the most commonly used is reactive ion etching (RIE), that is based on a continuous supply of reactive ions and radicals generated in a radio-frequency (RF) plasma discharge.

  5. 4. 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

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

    Master-uppsats, KTH/Tillämpad fysik
