  2. 6. Novel Possibilities for Advanced Molecular Structure Design for Polymers and Networks

    Author : Anna Finne; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ring-opening polymerization; coordination-insertion; germanium; cyclic tin alkoxides; spirocyclic initiators; poly L-lactide ; poly 1; 5-dioxepan-2-one ; triblock; star-shaped; network; functionalization; morphology; AFM; Polymer chemistry; Polymerkemi;

    Abstract : Synthetic and degradable polymers are an attractive choicein many areas, since it is possible to control the way in whichthey are manufactured; more specifically, pathways tomanipulate the architecture, the mechanical properties and thedegradation times have been identified. In this work,L-lactide, 1,5-dioxepan-2-one and ε-caprolactone were usedas monomers to synthesize polymers with different architecturesby ring-opening polymerization. READ MORE

  5. 8. Hybrid nano titania: molecular formation mechanisms and applications in nanotechnology

    Author : Fredric Svensson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nanomaterials are defined as materials with one dimension smaller than 100 nm. At this size, exotic properties start to emerge, making them interesting for a wide range of applications including catalysis, electronics, theranostics, and “smart materials”. READ MORE

    Author : Annika Pohl; Gunnar Westin; David A. Payne; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; sol-gel; alkoxide; doped manganites; CMR; perovskite; phase development; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

    Abstract : The development of more advanced materials forms the basis of technological progress. One group of fascinating compounds with many potential applications in spintronic devices are the mixed-valence perovskite manganites. READ MORE

  7. 10. Bispyridylamides as ligands in asymmetric catalysis

    Author : Oscar Belda de Lama; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; asymmetric catalysis; chiral ligand; pyridine; amide; allylic alkylation; enantioselective; cyanation; ring-opening; chiral Lewis acid;

    Abstract : This thesis deals with the preparation and use of chiralbispyridylamides as ligands in metal-catalyzed asymmetricreactions. The compounds were prepared by amide formation usingdifferent coupling reagents. READ MORE
