    Abstract : Saving energy in buildings is of great importance because about 30 to 40 % of the energy in the world is used in buildings. An electrochromic window (ECW), which makes it possible to regulate the inflow of visible light and solar energy into buildings, is a promising technology providing a reduction in energy consumption in buildings along with indoor comfort.

  4. 2. Femtosecond Dynamics and Photochemistry in Solution

    Author : Marcus Rasmusson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; cross-correlation function; chloroiodomethane; dihalides; bromobenzene; ion pairs; solvation; vibrational relaxation; charge-transfer; tetranitromethane; electron transfer; femtosecond spectroscopy; dissociation; Photochemistry; Fotokemi; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : The reaction dynamics of several polyatomic systems have been investigated in solution by femtosecond spectroscopy. Tetranitromethane-naphtalene complexes excited in the charge-transfer band at 400 nm undergo dissociative electron transfer, resulting in three primary products: [naphthalene].+, NO2 and C(NO2)3-.

  5. 3. Tuning electron transfer reactions by selective excitation in porphyrin-acceptor assemblies

    Author : Mikael Andersson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Abstract : This thesis concerns electron transfer reactions from different excited states in porphyrins, and the effect of changing the energy of the link connecting the donor and acceptor. Photoinduced electron transfer, and subsequent processes were studied using ultrashort laser pulses and nanosecond laser flash photolysis. READ MORE
