  2. 6. Dynamics of Excitation Transfer and Charge Separation in Polymeric Semiconductors

    Author : Arvydas Ruseckas; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anisotropy; Photoinduced absorption; Femtosecond spectroscopy; Polythiophene; Conjugated polymers; Donor-Acceptor Complexes; Carbazole; Charge separation; Excitation transfer; Recombination; Physics; Fysik;

    Abstract : Dynamics of optically excited electronic states have been studied in solid films and solutions of semiconducting polymers and model compounds. Transient absorption, monitored in the spectral range from 0.9 eV to 2.5 eV with a time resolution of about 100 fs, was the main experimental technique. READ MORE

  4. 7. Resonator sensor technique for medical use : an intraocular pressure measurement system

    Author : Anders Eklund; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor; Vibration; Hardness; Prostate; intraocular pressure; resonator; eye; applanation; glaucoma;

    Abstract : In the work of this doctoral dissertation a new resonator sensor technique, first presented in 1989, has been further developed and evaluated with focus on technical characteristics and applications within the medical field. In a first part a catheter-type tactile sensor using the resonator sensor technique was evaluated in a silicone model and applied to human prostate in vitro. READ MORE

  5. 8. Molecular organization and in situ assembly of the human skin barrier

    Author : Lianne den Hollander; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : A deficient skin barrier function is a characteristic feature of skin diseases such as eczema, psoriasis and the ichtyoses. A malformation of the lipid matrix might be a major factor in barrier deficient skin disease. READ MORE

  6. 9. Short Pulses in Engineered Nonlinear Media

    Author : Stefan Holmgren; Fredrik Laurell; Derryck Reid; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; KTiOPO4; frequency conversion; mode-locked lasers; ultra-fast lasers; visible lasers; short pulses; ultrafast nonlinear optics; diagnostic applications of nonlinear optics; nonlinear optical materials; Physics; Fysik;

    Abstract : Short optical pulses and engineered nonlinear media is a powerful combination. Mode locked pulses exhibit high peak powers and short pulse duration and the engineered ferro-electric KTiOPO4 facilitates several different nonlinear processes. READ MORE

  7. 10. Electron Wave Packet Dynamics on the Attosecond Time Scale

    Author : Kathrin Klünder; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photoionization; Single attosecond pulses; Attosecond pulse trains; Electron wave packet; Electron dynamics; Interferometry; Photoemission time delay; Fysicumarkivet A:2012:Klünder; Stark spectroscopy;

    Abstract : One objective of attosecond science is to study electron dynamics in atoms and molecular systems on their natural time scale. This can be done using attosecond light pulses. READ MORE
