    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Bilirubin; Phototherapy; Neonatal Jaundice; Femtosecond Spectroscopy; CASSCF; TD-DFT; Isomerisation Dynamics; Biophysical chemistry; Biofysikalisk kemi;

    Abstract : Bilirubin is a degradation product of haem, which is constantly formed in allmammals. Increased levels of bilirubin in humans lead to jaundice, a conditionthat is very common during the first days after birth. This neonataljaundice can routinely be treated by phototherapy without any serious sideeffects. READ MORE

    Abstract : Grätzel cells or Dye-Sensitized Solar Cells (DSSCs) are considered one of the most promising methods to convert the sun's energy into electricity due to their low cost and simple technology of production. The Grätzel cell is based on a photosensitizer adsorbed on a low band gap semiconductor. READ MORE
