  2. 1. Test Charge Response of a Dusty Plasma with Grain Size Distribution and Charging Dynamics

    Author : Muhammad Shafiq; Michael A. Raadu; Jens Juul Rasmussen; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Dusty plasmas; Complex plasmas; Grain size distribution; Grain charging dynamics; Lorentzian distribution; Kappa distribution; Test charge response; Delayed shielding; Energy loss; Drag force; Wake field.; Plasma physics; Plasmafysik;

    Abstract : This doctoral thesis reports analytical and numerical results for the electrostatic response of a dusty plasma to a moving test charge. Two important physical aspects of dusty plasmas, namely grain size distribution and grain charging dynamics were taken into account. READ MORE

  4. 2. Interaction Between Microgels and Oppositely Charged Proteins

    Author : Christian Johansson; Per Hansson; Brian Saunders; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; microgel; protein; uptake; distribution; core-shell; colloidal stability; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : This thesis reports on interactions between microgels and oppositely charged proteins. Two types of negatively charged microgels are investigated: poly(acrylic acid) microgels of 60-80 µm in diameter, and colloidal poly(NIPAM-co-acrylic acid) microgels of around 1 µm in diameter.

  5. 3. A new approach to the analyses of fluorescence depolarisation experiments in the presence of electronic energy transport

    Author : Oleg Opanasyuk; Lennart B-Å Johansson; Per-Olof Westlund; Yehudi Levine; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; electronic energy transfer; donor-donor energy migration; extended Förster theory; fluorescence depolarisation; two-photon excitation; computer simulations; genetic algorithms; fysikalisk kemi; Physical Chemistry;

    Abstract : A new and general procedure is described for a detailed analysis of time-resolved fluorescence depolarisation data in the presence of electronic energy migration. An isotropic ensemble of bifluorophoric molecules (D1-R-D2) has been studied to demonstrate its utility. READ MORE
