  2. 6. Polymorphism and Crystallization of p-Aminobenzoic Acid

    Author : Sandra Gracin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; controlled crystallization; polymorphism; p-aminobenzoic acid;

    Abstract : Polymorphs are solid phases where the chemical composition isequal but the crystal structure differs. Many organic compoundsmay appear in more than one crystalline structure. READ MORE

  4. 7. Atom transfer radical polymerization from multifunctional substrates

    Author : Anna Carlmark; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Abstract : Atom transfer radical polymerization (ATRP) has proven to be a powerful technique to obtain polymers with narrow polydispersities and controlled molecular weight. It also offers control over chain-ends. READ MORE

  5. 8. Dendrimers and dendronized polymers : synthesis and characterization

    Author : Andreas Nyström; Anders Hult; A. Dieter Schlüter; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; dendronized polymers; atom transfer radical polymerisation; ring-opening metathesis polymerization; reversible addition-fragmentation chain transfer polymerization; 2; 2-bis methylol propionic acid; tri-block copolymers; rheology; differential scanning calorimerty; 1H-NMR self-diffusion; Polymer chemistry; Polymerkemi;

    Abstract : The goal of this work was to synthesize complex macromolecular architectures such as dendrimers and dendronized polymers, and evaluate the effect from the dendrons on the optical and material properties. The work presented in this doctoral thesis, Dendrimers and Dendronized Polymers - Synthesis and Characterization, is divided into one minor and one major part. READ MORE

  6. 9. Synthetic development towards benzodiazepine alkaloids : total synthesis of circumdatin F and C

    Author : Anette Witt; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Alkaloids; benzodiazepines; cyclisation; Michael reactions; quinazolinones; synthesis.;

    Abstract : Benzodiazepine alkaloids exhibit a multitude of interesting pharmacological activities. This thesis deals with the development of synthetic methods towards such alkaloids, of which the main efforts can be divided into three parts. READ MORE

  7. 10. Factors influencing splanchnic microcirculation in animal models of endotoxaemia

    Author : Andreas Andersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Microcirculation;

    Abstract : Even though severe sepsis and septic shock therapy has improved in recent years, mortality remains high (22-50%). Disturbances in splanchnic organ homeostasis and increases in gut permeability have long been presumed to contribute to systemic inflammation and multiple organ dysfunction syndrome in critical illness and septic shock.
