  1. 1. Development of a PNA-drug conjugate for pretargeted delivery of cytotoxic drugs

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Theranostics

    Författare :Astrid Haraldsson; [2023]
    Nyckelord :PNA; pretargeting; cancer therapy; cytotoxic payload;

    Sammanfattning : One of the major challenges in cancer treatment is delivering high enough doses of active substance specifically to cancer cells without accumulation in healthy organs. Pretargeting has emerged as a potential solution, where the delivery of a cancer recognizing (primary) agent and a cancer killing (secondary) agent are separated. LÄS MER

  3. 2. Numerical simulations of ultrafast dynamics in plasmonic nanostructures

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Nils Henriksson; [2023]
    Nyckelord :Ultrafast nanophotonics; Three temperature model; Numerical simulations;

    Sammanfattning : Plasmonic effects in nanosized particles enhance the interaction between light and matter due to the localized surface plasmon resonance, with potential applications such as all-optical transistors and optical computers. Commonly, the dynamics of nanoparticles’ optical properties are assessed via pump-probe spectroscopy, where a plasmonic structure is exited by an initial laser, the pump. LÄS MER

  4. 3. Impact of nanoparticle plasmons on photoluminescense and upconversion processes in ZnO

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik; Uppsala universitet/Fysikalisk kemi

    Författare :Axel Gudmundsson; [2023]
    Nyckelord :Photoluminescence; Upconversion; Plasmons; ZnO;

    Sammanfattning : The increasing prevalence of glass windows in modern buildings has raised the demand for solar control windows that possess climate-appropriate properties. Glass windows made of abundant and low-cost materials which can both decrease the heating energy consumption as well as enhance the light climate indoors would sufficiently meet the goals of economical yet uplifting buildings.

  5. 4. Sputtered Transparent Contact Layers for Bifacial and Tandem Solar Cells

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Klara Kiselman; [2022]
    Nyckelord :Solar cells; ITO; indium doped tin oxide; bifacial cell; tandem cell; transparent conductive oxides;

    Sammanfattning : A key to solar cells with lower environmental impact is higher efficiency and reduced material usages. Bifacial solar cells may have a higher efficiency as light can enter from two directions and tandem solar cells may use a larger part of the incoming solar spectrum, increasing the efficiency.

  7. 5. Demonstration and investigation of hydrogen production by water splitting through plasmon assisted photocatalysis involving a cobalt catalyst.

    Magister-uppsats, Uppsala universitet/Fysikalisk kemi

    Författare :Amal Mendalz; [2022]
    Nyckelord :;

    Sammanfattning : Plasmonic heterostructures are of great interest within the industry and in the academia owing to theirapplications in photovoltaics and photocatalysis. The Localised surface plasmon resonance (LSPR) leading to an intensification of the electromagnetic (EM) field on the surface of the plasmonic nanoparticles results in an efficient absorption of light over miniscule thickness of the material.
