  1. 26. Pool Boiling on Structured Surfaces: Heat Transfer and Critical Heat Flux : Experiments and Mechanistic Modelling

    Författare :Zhen Cao; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pool boiling; heat transfer; critical heat flux; bubble dynamics; surface modification;

    Sammanfattning : In this thesis, pool boiling heat transfer was experimentally studied on structured surfaces with dielectric liquids (HFE-7200, NOVEC-649, FC-72), organic liquids (Acetone, Pentane) and deionized water.In the first step, nanoparticle coatings on copper surfaces were prepared by an electrophoretic deposition method, with Cu-Zn nanoparticles (100 nm) and Cu nanoparticles (150 nm).

  3. 27. Nanowire devices for X-ray detection

    Författare :Lert Chayanun; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanowires; Nanowire solar cells; X-ray detectors; X-ray beam induced current;

    Sammanfattning : High spatial resolution X-ray microscopy has become a dedicated tool to study nanocrystals and nanostructure devices in recent years. In general, the spatial resolution of X-ray microscopy depends on the spot size of the X-ray beam and the pixel size of X-ray detectors. LÄS MER

  4. 28. Photophysics of Perovskite Nano- and Microcrystals

    Författare :Junsheng Chen; NanoLund: Centre for Nanoscience; []

    Sammanfattning : The demand and consumption of energy is increasing dramatically all around the world. Broad adoption of fossil fuels has triggered an enormous threat to the environment. To ensure sustainability of our species and habitat, new solutions to fulfill the energy demand have to be found. LÄS MER

  5. 29. Binding Kinetics of Proteins at Immune-Cell Contacts

    Författare :Manto Chouliara; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; T cells; Binding Kinetics; Affinity; Lifetime; CD4; CD2; TIRF Microscopy; SLBs;

    Sammanfattning : Protein-protein interactions are crucial in numerous cellular functions and biological processes that take place inside our body. It is therefore not surprising that these interactions also govern the response of our body´s defence mechanism, the so-called immune system, towards an infection. LÄS MER

  7. 30. Scanning probe techniques as an investigation tool for semiconductor nanostructures and devices

    Författare :Jovana Colvin; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; III-V semiconductors; AFM; STM; KPM; SCM; c-AFM; Crystal growth; Doping; Defects;

    Sammanfattning : Semiconductor nanostructure based devices provide new opportunities for contributing to a sustainable energy usage. This includes harvesting of energy (solar cells) and saving of energy, e.g. in lighting (light-emitting diodes, LEDs) and transfer of energy (power devices). LÄS MER
