  2. 1. Femtosecond Dynamics of Dissociation and Isomerization Reactions in Solutions

    Author : Jose-Luis Alvarez; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optics; Electromagnetism; Photochemistry; Fotokemi; acoustics; Elektromagnetism; optik; akustik; Fysicumarkivet A:1997:Alvarez;

    Abstract : The main purpose of this work has been to investigate the fundamental dynamics of photodissociation and photo-induced isomerization reactions in the condensed phase. These "elementary" reactions have been chosen as model processes for exploring the influence of the solvent on a chemical event, as well as the factors that control this influence. READ MORE

  4. 2. Photon induced fluorescence studies of molecules using synchrotron radiation

    Author : Jesús Álvarez Ruiz; KTH; []
    Keywords : Fluorescence; synchrotron radiation; superexcited states; UV.;

    Abstract : This Licentiate thesis presents research accomplished at theSection of Atomic and Molecular Physics at the Royal Instituteof Technology in Stockholm using photon induced fluorescencespectroscopy (PIFS) during the last two years.The main results presented are summarized:- Neutral photodissociation in CO was observed aftersynchrotron photon excitation in the range 19-26 eV bycollecting dispersed fluorescence from excited neutral C atoms.

  5. 3. Synchrotron radiation induced fluorescence spectroscopy of gas phase molecules

    Author : Jesús Álvarez Ruiz; Elisabeth Rachlew; J. E. Rubensson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; molecular spectroscopy; photon induced fluorescence; synchrotron radiation; superexcited states; Fysik; Physics; Fysik;

    Abstract : A new experimental set-up for gas phase fluorescence studies using synchrotron radiation has been designed and constructed to perform simultaneously total and dispersed fluorescence measurements. Neutral photodissociation of CO has been investigated after excitation with 19-26 eV photons. READ MORE

  6. 4. Design and Synthesis of Amine Building Blocks and Protease Inhibitors

    Author : Susana Ayesa Alvarez; Bertil Samuelsson; Thomas Olsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : The first part of this thesis addresses the design and synthesis of amine building blocks accomplished by applying two different synthetic procedures, both of which were developed using solid-phase chemistry. Chapter 1 presents the first of these methods, entailing a practical solid-phase parallel synthesis route to N-monoalkylated aminopiperidines and aminopyrrolidines achieved by selective reductive alkylation of primary and/or secondary amines.

  7. 5. Nanocellulose-based materials: from colloidal assembly to functional films

    Author : Yingxin Liu; Lennart Bergström; German Salazar-Alvarez; Orlando Rojas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials Chemistry; materialkemi;

    Abstract : The assembly of nature-based nanomaterials into complex architectures is both a design principle of biological composites, e.g., wood and nacre with outstanding properties and a promising route for developing functional macroscopic materials. READ MORE
