  1. 21. Simulation of Microwave Heating of Healthy and Cancerous Human Tissue With Gold Nanoparticles

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hampus Carlens; Mika Söderström; [2022]
    Nyckelord :Gold nanoparticle GNP ; Electrophoretic resonance; Dispersive permittivity; Cancer treatment; Waveguide; Radiotherapy; Graded material.;

    Sammanfattning : With a great need for new and better cancer treatments, microwaves and gold nanoparticles (GNPs) are increasingly being suggested to be used in radiotherapy. In thisreport, the authors present an investigation of how human tissue,both malignant and healthy, behaves under microwave radiation. LÄS MER

    Sammanfattning : Nanopartiklar är partiklar med storlekar i området 1 till 100 nm, och som uppvisar nanospecifika egenskaper. Egenskaperna kan variera helt mellan olika typer av nanopartiklar, även bland partiklarna och deras respektive material i bulk format på grund av deras unika storlekar, former och strukturer.

  5. 24. Water-based Synthesis of Superparamagnetic X-ray Fluorescent Contrast Agents

    Master-uppsats, KTH/Tillämpad fysik

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

    Sammanfattning : 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. LÄS MER

  7. 25. Nanoscale characterisation of model Ni-Mo catalyst active phases

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Centrum för analys och syntes

    Författare :Jonas Elmroth Nordlander; [2022]
    Nyckelord :Ni-Mo catalysts; Hydrodeoxygenation; TEM; PXRD; Materials chemistry; Chemistry;

    Sammanfattning : An important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. LÄS MER
