  1. 1. The Light-up Probe

    Författare :Nicke Svanvik; Chalmers University of Technology; []
    Nyckelord :asymmetric cyanine dyes; light-up probes; PNA; real-time PCR; LightUp Probe; fluorescent hybridization probes; homogeneous hybridization assays;

    Sammanfattning : The work presented in this thesis concerns the development of light-up probes and their potential applications in PCR based molecular diagnostics. The light-up probe is a nucleic acid analog (here PNA) oligomer linked to an asymmetric cyanine dye (here thiazole orange) and it combines the excellent hybridization properties of PNA with the large fluorescence enhancement of the dye upon binding to DNA.

    Sammanfattning : This thesis presents HELIOS, an in-house laboratory for time-resolved pump-probe spectroscopy with extreme-ultraviolet (XUV) probe radiation. A wide span of pump wavelengths can be generated using commercial laser equipment while XUV probe radiation is generated via a high harmonic generation process in a noble gas delivering probe photons with energies between 20 eV and 72 eV.

  5. 5. Fluid Dynamics of the Transport Zone of Circulating Fluidized Beds - with Application to Boilers

    Författare :Wennan Zhang; Chalmers University of Technology; []
    Nyckelord :fluid dynamics; particle flux probe; momentum probe; circulating fluidized bed boilers; circulating fluidized beds; particle flow pattern; particle concentration probe; spectrum analysis;

    Sammanfattning : The particle suspension flow structure in circulating fluidized beds (CFB) was studied with emphasis on the layer of downflowing particles at the wall. The main experiments were carried out in the furnace of the 12 MWth CFB boiler of 1.7x1.7 m cross-section, and in a two-dimensional CFB cold bed of 0. LÄS MER
