  1. 1. Deposition av Black carbon i sjöar efter den stora skogsbranden i Västmanland 2014

    Magister-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC); Lunds universitet/Miljövetenskaplig utbildning

    Författare :Danny Wong; [2023]
    Nyckelord :Black carbon; BC; climate; environment; wildfire; boreal forests; lake sediments; Västmanland.; Earth and Environmental Sciences;

    Sammanfattning : Black carbon (BC) is produced during incomplete combustion of Biomass and fossil fuels. BC and other carbonaceous pollutants have characteristics that affect the climate, environment, and human health. Historically, BC emissions have been measured and monitored in the atmosphere, and BC emissions to the air are quite well documented. LÄS MER

  3. 2. Computational study of the photophysical properties of two related photosensitizer proteins

    Master-uppsats, KTH/Kemi

    Författare :Benjamin Fégeant; [2023]
    Nyckelord :Photosensitizer proteins; QM MM; photophysics; molecular dynamics; computational protocol for protein preparation; Fotosensibiliserande proteiner; QM MM; fotofysik; molekylär dynamik; beräkningsprotokoll för förberedelser av proteiner;

    Sammanfattning : Den ökande koldioxidhalten i atmosfären har lett till ett ökat intresse för användning av solljus, ett exempel är inom kemi. Att använda ljus i kemi kan leda till nya och intressanta kemiska reaktioner och kan tillämpas i användningsområden som exempelvis fotokatalys och fotovoltaik. LÄS MER

  4. 3. Borne in Fire - A Study of Black Carbon Emitted from Coal Fired Power Plants in West Bengal, India.

    Master-uppsats, Linköpings universitet/Institutionen för tema

    Författare :Ra'eesah Hendricks; [2023]
    Nyckelord :Black Carbon; Chemothermal Optical Method; Health Impacts; Particulate Matter 2.5; Thermal Optical Reflectance Method;

    Sammanfattning : Black carbon has been reported to have major impacts on climate, environmental quality, and health. A chemothermal oxidation method, ordinarily used to isolate black carbon from soils, sediments and aquatic samples was applied to explore atmospheric samples. LÄS MER

  5. 4. 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

  7. 5. Surface orientation of the formamidinium cation in black formamidinium lead iodide perovskite

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Torsten Geirsson; [2023]
    Nyckelord :Perovskite; Formamidinium; Surface;

    Sammanfattning : Formamidinium lead iodide perovskite (FAPI) holds promise to be used in high–efficiency solar cells. A comprehensive understanding of the immediate surface properties of this material can provide insights into its interaction with other materials and guide future engineering of its interface with other constituents of the solar cell.
