  1. 1. Synthesis and Characterization of Materials for Carbon Based Hybrid Asymmetric Supercapacitor Electrodes

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Avital Cherednik; [2023]
    Keywords : Supercapacitor; hybrid supercapacitor; metal oxide nanoparticles; carbon electrodes; ionic liquid; Superkondensator; hybrid superkondensator; metaloxid nanopartiklar; kolelektroder; jonvätska;

    Abstract : Superkondensatorer är energilagringsenheter som har uppmärksammats mer under det senaste decenniet. Några av de fördelar som dessa enheter har varit är lagring av hög effekttäthet, förlängda livscykler och snabba laddnings- och urladdningstider. READ MORE

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

    University essay from Uppsala universitet/Solcellsteknik; Uppsala universitet/Fysikalisk kemi

    Author : Axel Gudmundsson; [2023]
    Keywords : Photoluminescence; Upconversion; Plasmons; ZnO;

    Abstract : 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.

  4. 3. Water-based Synthesis of Superparamagnetic X-ray Fluorescent Contrast Agents

    University essay from KTH/Tillämpad fysik

    Author : Daniel Cortés García; [2022]
    Keywords : Nanoparticles; SPIONs; XFCT; co-precipitation.; Nanopartiklar; SPIONs; XFCT; samfällning;

    Abstract : Nowadays, nanomedicine is one of the most important application areas fornanoparticles (NPs), where the design and synthesis of new hybrid nanostructures have attracted much interest, when combining properties and functionalities from different constituents. For example, they have been extensivelyused for dual-mode imaging. READ MORE

  5. 4. Graphene Quantum Dots as Fluorescent and Passivation Agents for Multimodal Bioimaging

    University essay from KTH/Tillämpad fysik

    Author : Nüzhet Inci Kilic; [2021]
    Keywords : graphene quantum dots; hybrid nanoparticles; x-ray fluorescence contrast agents; multimodal bioimaging; grafen-kvantprickar; hybrida nanopartiklarna; multimodal bioavbildning; röntgenfluorescens kontrastmedel;

    Abstract : Zero-dimensional graphene (carbon) quantum dots have been drawing attention in bio-related applications since their discovery, especially for their optical properties, chemical stability, and easily modifiable surface.  This thesis focuses on the green synthesis of nitrogen-doped graphene quantum dots (GQDs) for dual-mode bioimaging with X-ray fluorescence (XRF) and optical fluorescence.

  6. 5. Easy-to-clean properties in coatings for automotive applications

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Weyni Ghebreamlak; [2021]
    Keywords : Easy-to-clean surface; sol-gel; superhydrophobicity; superoleophobicity; nanoparticles; Lätt-att-rengöra yta ”Easy-to-clean” ; sol-gel; superhydrofobicitet; superoleofobicitet; nanopartiklar;

    Abstract : En ”lätt-att-rengöra” yta definieras som en yta som stöter bort vatten och smuts. I detta projekt har klarlack med olika sammansättningar studerats i syfte att introducera egenskapen ”lätt-att-rengöra”. För att uppnå denna egenskap måste beläggningen vara superhydrofob och oleofob. READ MORE
