  1. 1. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging

    Master-uppsats, KTH/Kemi

    Författare :Arezu Sehati; [2023]
    Nyckelord :Coherent Diffraction Imaging; X-ray Free Electron Lasers; Refractive index; Core-shell nanoclusters; Rare-gas ionization; Koherent Diffraktionsavbildning; Röntgenfrielektronlaser; Brytningsindex; Core-shell-nanokluster; Ädelgasjonisering;

    Sammanfattning : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. LÄS MER

  3. 2. Core-Shell Superparamagnetic Iron Oxide Nanoclusters for Bioconjugation

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Ronak Kakadiya; [2022]
    Nyckelord :Nanoparticles; Nanoclusters; SPIONs; Microwave-assisted synthesis; Solvothermal; Core-Shell; Bioconjugation; Green Chemistry.; Nanopartiklar; Nanokluster; SPIONs; Mikrovågsassisterad syntes; Solvotermisk; Core-Shell; Biokonjugation; Grön kemi.;

    Sammanfattning : Nanoparticles (NPs) have been part of our daily lives whether we are aware of it ornot and are continuously shaping our world of tomorrow. They are employed in awide range of applications such as in sunscreens, breaking down microplastics inthe ocean and scaling down beyond Moore’s law. LÄS MER

  4. 3. Carbon-coated Lead Halide Perovskite Quantum Dots and Copper(I)Iodide Coated Copper Nanowire Electrodes for Flexible Solar Cells

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Albin Andersson; [2022]
    Nyckelord :Nanotechnology; solar cells; perovskite; quantum dots; nanowire; thin film electrodes; nanoteknologi; solceller; perovskit; kvantprickar; nanotrådar;

    Sammanfattning : Lead Halide Perovskite is emerging quickly as a promising material for the future solar cellsthanks to their inherent good optoelectrical properties along with their cheap and facile fabri-cation. However, their main drawback before commercialization is their weak stability. LÄS MER

  5. 4. Tuning the composition of metallic nanoparticles for catalytic applications

    Master-uppsats, KTH/Kemi

    Författare :Anthony Ropp; [2021]
    Nyckelord :catalysis; nanoparticles; frustrated Lewis pairs; synthesis; core-shell;

    Sammanfattning : Industries’ interest in nanomaterials is tremendous and catalysis is one of their applications. Catalysts allow reactions to occur under milder conditions, avoiding committing excessive heat or pressure to foster reactions. LÄS MER

  7. 5. Development of magnetic lignin nanoparticles from low-molecular-weight eucalyptus and spruce lignin fractions

    Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Anna Wessén; Eliot Diklev; Lejla Al-Tamimi; [2020]
    Nyckelord :Magnetic nanoparticles; Hardwood; Softwood; Self-assembly; Lignin;

    Sammanfattning : Lignin is one of the most common biopolymers in the world. Together with cellulose andhemicellulose it constitutes the fibers in the wood. It has a high molecular weight due to its complexstructure consisting of crossed-linked phenolic monomers and is concatenated with different types ofcarbon and ether bonds. LÄS MER
