  2. 1. Slow and stopped light by light-matter coherence control

    Author : Jonas Tidström; Lars Thylén; Mauritz Andersson; Jesper Mørk; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slow light; stored light; stopped light; light-matter coherence; electromagnetically induced transparency; rubidium atoms; Physics; Fysik; Photonics; Fotonik;

    Abstract : In this thesis we study light-matter coherence phenomena related to the interaction of a coherent laser field and the so-called Λ-system, a three-level quantum system (e.g., an atom). We observe electromagnetically induced transparency (EIT), slow and stored light in hot rubidium vapor. READ MORE

  4. 2. Major Intrinsic Proteins - Structure, function, interactions

    Author : ANDREAS KIRSCHT; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aquaporin; membrane proteins; crystallography; stopped-flow; molecular dynamics; structure modeling;

    Abstract : Major intrinsic proteins, also referred to as aquaporins (AQPs) are localized in membranes of all domains of life to increase the permeability to water or other small, polar molecules. Several monophyletic groups can be discerned in this large and divergent protein superfamily. READ MORE

  5. 3. Mechanism and Regulation of Initiation of Protein Synthesis in Eubacteria

    Author : Ayman Antoun; Måns Ehrenberg; John Hershey; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Initiation; Protein Synthesis; Initiation Factors; Light Scattering; Ribosomes; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : Initiation of protein synthesis in E.coli involves several steps, which lead to the formation of the first peptide bond. This process requires three initiation factors: IF1, IF2 and IF3. READ MORE

  7. 5. Peroxyoxalate Chemiluminescence for Miniaturized Analytical Flow Systems

    Author : Tobias Jonsson; Umeå universitet; []
    Keywords : peroxyoxalate; chemiluminescence; nucleophilic catalysis; non-nucleophilic base; imidazole; triazole; aminopyridine; miniaturized; flow system; capillary electrophoresis; multivariate; analytisk kemi; Analytical Chemistry;

    Abstract : This thesis deals with the peroxyoxalate chemiluminescence (POCL) reaction and its application as a detection technique in flow systems for chemical analysis. Particularly, miniaturized flow systems aimed for separation of molecules. READ MORE
