  1. 1. Testing aerosol vertical profiling methods with portable instruments on unmanned and manned aircraft

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Ellen Grace Soroka; [2023]
    Nyckelord :Physical Geography; Ecosystem Analysis; Aerosols; Vertical Profile; Black Carbon; PM2.5; Nanoparticles; UAV; Drone; Master degree thesis; 30 credits in Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

    Sammanfattning : This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. LÄS MER

  3. 2. Characterization of a new type of nanoparticle generator for medical inhalation applications

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :André Nagy; [2020]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : A new type of nanoparticle generator is being developed at Lund University. This project aimed to characterize it in order to produce a stable aerosol for medical inhalation applications. This project characterized size distributions during different parameter settings for the generator. LÄS MER

  4. 3. The Production of Samarium-Cobalt Nanoparticles Using a Spark Discharge Generator

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

    Författare :Timothy Lewis; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this project I attempt to press custom electrodes from Sm and Co powder using two different pressing tools. I investigate if custom electrodes can generate nanoparticles with tailored properties using a spark discharge generator (SDG). LÄS MER

  5. 4. Exposure of zinc oxide nanoparticles on lung epithelium: A comparison between submerged and air-liquid interface cultures

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi
