2. 1. 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

4. 2. Mass Transport Properties in Supramolecular Systems Studied by Diffusion and Relaxation NMR

   Author : Patrik Jarvoll Dae; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NMR; T2; diffusion; hydrogel; exchange dynamics; T1; magnetic susceptibility; organosilica nanoparticles; microstructure; relaxation; supramolecular systems;

   Abstract : This thesis shows how diffusion and relaxation NMR can be applied in various aspects to study mass transport in supramolecular systems. Information about these systems can be obtained, either by direct measurement of the molecules that are incorporated in a supramolecular structure, or via probe molecules, which indirectly gives information about the system.

5. 3. Functional Dendritic Materials using Click Chemistry : Synthesis, Characterizations and Applications

   Author : Per Antoni; Anders Hult; Michael Malkoch; Stefan Hecht; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dendrimer; Dendron; Dendritic; Hyperbranched; Click; Chemistry; CuAAc; One-Pot; Multi-functional; Simultaneous; Honeycomb; Isoporous; MALDI; NMR; GPC; TGA; DSC; Polymer chemistry; Polymerkemi;

   Abstract : Förfrågan efter nya och mer avancerade applikationer är en pågående process vilket leder till en konstant utveckling av nya material. För att förstå relationen mellan en applikations egenskaper och dess sammansättning krävs full förståelse och kontroll över materialets uppbyggnad. READ MORE

6. 4. Carbohydrate-Based Inhibitors of Pathogen Adhesion to Cell Surface Glycoconjugates

   Author : Henrik C Hansen; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galabiose analogs; Globotriose analogs; Escherichia coli; verotoxin; PapG adhesion; Streptococcus suis; Dendrimers; Multivalency; Amino-deoxy analogs; Organic chemistry; Inhibitor; Ceramide analogs; Glycoconjugates; Organisk kemi;

   Abstract : The fact that a growing number of pathogens develop resistance against traditional treatment is a growing medical problem. Infections, which until now have been harmless, might turn into life threatening diseases. These problems have led to an intensified search for alternative treatments. Analogs of cell surface glycoconjugates are an alternative. READ MORE

7. 5. Synthesis and characterization of dendritic macromolecules based on 2,2-bis(hydroxymethyl)propionic acid

   Author : Henrik Ihre; KTH; []
   Keywords : ;

   Abstract : Dendrimers are a relatively new type of macromolecules characterized by a well-defined, highly branthed, layered structure with a multitude of chain ends, adopting a globular shape at higher molar masses. Dendrimers are usually constructed from ABx type of monomers in either one of the two step-wise approaches known as thedivergentor theconvergent growth approach. READ MORE
