  2. 1. Branched aliphatic polycarbonates : synthesis and coating applications

    Author : Peter Löwenhielm; KTH; []
    Keywords : polymer technology;

    Abstract : The overall aim of this thesis is to describe the synthesisof branched aliphatic polycarbonates and show the potentialapplication of these polymers in the field of powder coatings.The characterization of the polycarbonates was facilitated bythe study of a series of bis-MPAdendrimers, which served asreference of perfectly branched polymers.

  4. 2. Synthesis and Properties of Branched Semi-Crystalline Thermoset Resins

    Author : Hans Claesson; KTH; []
    Keywords : star-branched; semi-crystalline; comb-branched; ring-opening polymerization; poly ƒÕ-caprolactone ; dendritic; thermoset; low temperature curing; powder coating; UV-curing; poly 5; 5-dimethyl-1; 3-dioxane-2-one ; size exclusion chromatography; rheology;

    Abstract : This thesis describes the synthesis and characterization ofbranched semi-crystalline polymers. Included in this work isthe SEC characterization of a series of dendrimers. Thebranched semi-crystalline polymers were synthesized in order toinvestigate the concept of their use as powder coatings resins. READ MORE

  5. 3. Assembling and Unraveling Carbohydrates Structures : Conformational analysis of synthesized branched oligosaccharides

    Author : Thibault Angles d'Ortoli; Göran Widmalm; Christian Marcus Pedersen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Convergent carbohydrate synthesis; Super-armed donors; Glycosylation; Conformational analysis; NMR; Chemical shift prediction; organisk kemi; Organic Chemistry;

    Abstract : Advances in the elaboration of vaccines and enzyme inhibitors rely on acquiring more knowledge about protein-carbohydrate binding events. Furthermore, the relationships between biological function and the three-dimensional properties of large glycans can be studied by focusing on the structural components they contained, namely, by scaling down the system under analysis.

  6. 4. Rheology and UV-curing of a star-branched polyester

    Author : Hans Claesson; KTH; []
    Keywords : Powder coating; UV-curing; star-polymer; gel point; alipahtic polyester; rheology; dendritic;

    Abstract : The use of powder coatings has increased steadily over thelast few decades. Their popularity is due to a number of majoradvantages they offer when compared to solvent-borne systems.Near zero VOC-content, reduced energy consumption and near 100%utilisation of the material are some of the advantages.

  7. 5. Padlock Probes and Rolling Circle Amplification : New Possibilities for Sensitive Gene Detection

    Author : Maritha Mendel-Hartvig; Pål Nyrén; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Padlock probes; RCR; in situ hybridization; branched DNA; Genetik; Clinical genetics; Klinisk genetik; Medical Genetics; medicinsk genetik;

    Abstract : A series of novel methods for detection of known sequence variants in DNA, in particular single nucleotide polymorphism, using padlock probes and rolling circle replication are presented. DNA probes that can be circularized – padlock probes – are ideal for rolling circle replication. READ MORE
