  2. 16. Symmetry in Asymmetric Catalysis and Hydrogen Bond-Based Self-Assembly : Synthesis and Investigations

    Author : Yutang Li; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; asymmetric catalysis; bissalen; asymmetric ring opening; pseudo-Cs; hydrogen bonding; self-assembly; C3 symmety; trilactam; scXRD; solubility; epoxidation; rearrangement; Baeyer-Villiger reaction; transition state; DFT calculation; cyclodextrin; polyethylene glycol; amphiphilicity;

    Abstract : The thesis elaborates on four different projects focusing on synthesizing symmetry-related molecules and investigating their performance as catalysts for asymmetric catalysis or as monomers for hydrogen bond-based self-assembly.Chapter 2 describes a new method to desymmetrize a meso-ligand.

  4. 17. Functional Degradable Polymers : from the monomeric point of view

    Author : Peter Olsén; Ann-Christine Albertsson; Karin Docent; Andrew Dove; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Degradable polymers is key, within the future vison, of creating a sustainable society were all aspects, cradle to grave, can be realized in a sustainable way. It is imperative to consider, how the monomer is formed, its polymerization, the material properties created and the final degradation behavior. READ MORE

  5. 18. Towards the Rational Design of Molecularly Imprinted Polymers

    Author : Håkan S Andersson; Ann-Christin Koch-Schmidt; Ian A Nicholls; Klaus Mosbach; Richard F Venn; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermodynamics; Molecular Recognition; Polyvalency; Cooperativity; Electrostatic Interactions; Hydrophobic Effect; Chromatography; Frontal Analysis; HPLC; Spectroscopy; Molecularly Imprinted Polymer; Molecular Imprinting; Crown Ether; Template Polymerisation; Cyclodextrin; Biochemistry; Metabolism; Biokemi; Biotechnology; Bioteknik; molecular recognition; Biokemi;

    Abstract : Molecular imprinting is a technique by which polymeric materials selective for a given target molecule can be created through a casting procedure. Functionalised monomers are added to a solution of molecular templates. READ MORE

  6. 19. Large scale synthesis of polyesters with low amount of residual tin

    Author : Anna Stjerndahl; Ann-Christine Albertsson; Johan Lind; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Abstract : Användningen av resorberbara polymerer för applikationer inom vävnadsersättning har ökat markant under de senaste decennierna. Tekniken innebär att celler får växa på ett polymert bärarmaterial och på så sätt återskapa skadad vävnad, och är ett lovande alternativ till många av de implantat som används idag. READ MORE

  7. 20. Protein folding studies of human superoxide dismutase and ALS associated mutants

    Author : Mikael Lindberg; Mikael Oliveberg; Jane Clarke; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; superoxide dismutase; ALS; protein folding; equilibrium titration; protein stability; apo protein; disulphide bridge; chevron plot; Biokemi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : Proteins are among the most abundant biological macromolecules. The cellular machinery is coupled to exact structural shape and properties of the more than 100 000 different proteins. Still, proteins can sometimes completely change their character and as a result trigger neuro degenerative disease. READ MORE
