  1. 1. Advective Collisions in Random Flows

    Author : Kristian Gustafsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In nature, suspensions of small particles in fluids are common. An important example are rain droplets suspended in turbulent clouds. Such clouds can start to rain very quickly and the reason for this is still not fully explained, but it is believed that the turbulent motion in the cloud plays an important role. READ MORE

  3. 3. Infrared spectroscopy of O2 and N2 adsorption on the clean and hydrogen covered Pt(111) surface

    Author : Kristian Gustafsson; Chalmers University of Technology; []
    Keywords : Infrared Spectroscopy; Adsorption; Hydrogen; Nitrogen; Pt 111 ; Oxygen;

    Abstract : This thesis is devoted to the investigation of O2and N2 adsorption on the clean and the hydrogen covered Pt(111) surface. Using infrared reflection absorption spectroscopy (IRAS) both physisorbed and chemisorbed molecular adsorptionstates have been identified and characterized via theircharacteristic internal vibration spectra.

  4. 4. The growth of waves by wind as a problem in nonequilibrium statistical mechanics

    Author : Anthony Bonfils; John Wettlaufer; Kristian Gustafsson; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; out-of-equilibrium system; fluctuation spectrum; oscillatory force; classical Casimir effect; non-linear waves; wave turbulence; wind-wave coupling.; teoretisk fysik; Theoretical Physics;

    Abstract : In 1948, Casimir predicted a net attractive force between two perfectly conducting parallel plates due to electromagnetic vacuum fluctuations. By analogy, the interaction of two ships on a wavy sea has been named Maritime Casimir effect. This is an example of force generation in non-equilibrium systems. READ MORE
