  1. 21. Mechanosensing Using GaInP Nanowires

    Författare :Zhen Li; Fasta tillståndets fysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Traction force; fluorescent nanowires; morphology; migration; Fysicumarkivet A:2018:Li;

    Sammanfattning : Mechanical forces exists in many cellular processes, including cell proliferation, migration, rearrangement and differentiation. The transformation of cancer cells from normal cells, cancer metastasis and cell rearrangement during morphogenesis all involve changes in cellular mechanical forces. LÄS MER

  3. 22. Quantum memory development and new slow light applications in rare-earth-ion-doped crystals

    Författare :Qian Li; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum memories; Slow light; Rare-earth-ion-doped crystals; Light-Matter Interaction; Fysicumarkivet A:2018:Li;

    Sammanfattning : When doped into solid state transparent crystals, rare-earth ions can have optically excited states with milliseconds coherence time and up to six hours coherence time for hyperfine levels after being cooled down to liquid helium temperature. This long coherence property makes them unique as solid state material and attractive for quantum information applications. LÄS MER

  4. 23. Development and Application of Laser-Induced Emission Techniques for Combustion Diagnostics -High-Resolution Visualization of Turbulent Reacting Flows

    Författare :Bo Li; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PLIF; LIF; Laser-Induced Fluorescence; Rayleigh scattering; Laser Diagnostics; flame font; Combustion; Turbulence; Photofragmentation LIF; PF-LIF; Laser-induced Phosphorescence; LIP; Fysicumarkivet A:2012:Li;

    Sammanfattning : Nowadays, more than 90% of our energy comes from combustion processes. Hence, it is very important to perform combustion research to reduce emissions, improve efficiency, find clean and renewable fuels, strengthen safety, etc. LÄS MER

  5. 24. Advanced Optical Diagnostics in Particle Combustion for Biomass and Metal as Alternative Fuels

    Författare :Shen Li; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical diagnostics; Quantitative measurement; Iron powder; Biomass; High-speed imaging; Digital holography; 3D reconstruction; SEM; Fysicumarkivet A:2022:Li;

    Sammanfattning : The energy sector is in urgent need for carbon-free strategies considering environmental pollutions and climate change impact. Two kinds of solid fuels, biomass and metal particles have been studied in this thesis aiming at CO2 emission reduction or zero carbon emission. LÄS MER
