  1. 1. Cirrus Clouds; Study of Microphyscial Properties and Their Seasonal & Temperature Dependence in the Tropics and Mid-latitudes

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Magdalena Sofia Maria Folestad; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Cirrus clouds are high-level ice clouds covering ≈ 30% of Earth’s surface. The cirrus clouds ice crystals can be formed by heterogeneous or homogeneous nucleation, where temperatures for heterogeneous nucleation was set to -38 - -30 °C and for homogeneous nucleation below -42 °C.

  4. 3. Understanding Sn-seeded InSb nanowire growth

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

    Författare :Hengfang Zhang; [2017]
    Nyckelord :Science General;

    Sammanfattning : III-Sb semiconductor nanowires have drawn a lot of attention because of their many promising applications, such as thermoelectric generation, low power high efficient electronics and quantum transport. Gold as a catalyst seed particle has been dominating for many years assisting nanowires growth. LÄS MER

  5. 4. Freezing in Fire Sprinkler Systems During Activation at Low Temperatures

    Magister-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Kamil Oskar Bialas; [2011]
    Nyckelord :Freezing Fire sprinkler system ice growth ; Technology and Engineering;

    Sammanfattning : The subject of this thesis is theoretical examination of freezing phenomena inside fire sprinkler systems during activation at low temperatures in the surroundings. Many sprinkler systems are installed in environments such that they must be operable at subfreezing temperature conditions. LÄS MER
