  1. 16. Studies on Domain Dynamics in Nonlinear Optical Ferroelectric Oxide Crystals

    Författare :Hoda Kianirad; Fredrik Laurell; Carlota Canalias; Sakellaris Mailis; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

    Sammanfattning : Nonlinear optical frequency conversion is the key technology for modifying laser output radiation, in order to target specific applications. The most powerful technique to obtain tailored second-order nonlinear interactions is the quasi-phasematching (QPM) approach. LÄS MER

  3. 17. Studies on Domain Wall Properties andDynamics in KTiOPO4 and Rb-doped KTiOPO4

    Författare :Gustav Lindgren; Carlota Canalias; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : KTiOPO4 (KTP) and Rb-doped KTP (RKTP) are two of the most attractive nonlinear opticalmaterials for engineering of periodically poled domain structures, commonly used as frequencyconversiondevices for laser radiation via the quasi-phase matching (QPM) technique. Thesematerials have excellent non-linearity, wide transparency windows and high resistance to opticaldamage. LÄS MER

  4. 18. Lattice Boltzmann simulations of tracer diffusion in microswimmer suspensions

    Författare :Henrik Nordanger; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lattice Boltzmann; microswimmers; active matter; enhanced diffusion;

    Sammanfattning : Suspensions of microswimmers are a class of systems inherently out of equilibrium, due to the mechanical work continuously performed by a large number of active agents. Biological examples are plentiful, as many aquatic microorganisms have the ability to propel themselves. LÄS MER

  5. 19. Vibrations, damping and power dissipation in Car Tyres

    Författare :Martin Fraggstedt; Svante Finnveden; Ines Lopez; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Acoustics; Akustik;

    Sammanfattning : Traffic is a major source of green house gases. The transport field stands for 32 % of the energy consumption and 28 % of the total CO2 emissions, where road transports alone causes 84 % of these figures. LÄS MER

  7. 20. CO studies of Herbig-Haro regions

    Författare :René Liseau; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : High resolution CO (J=1-0) observations of HH 7-11 in NGC 123? and the region around Lk Ha 224 in NGC 7129, using the 25m Millimeter Wave Telescope at Onsala, Sweden, have resulted in detailed maps. These dark cloud regions, forming stars of low to intermediate mass, show signs of shock excitation, identified as Herbig-Haro objects and H?0 masers. LÄS MER
