1. 6. Free Volume and Mesopores in Polymer Nanocomposites

   Författare :Petra Winberg; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemical technology and engineering; Kompositmaterial; Composite materials; Macromolecular chemistry; permeability ; membrane ; positron annihilation ; fumed silica ; clay ; mesopores ; polymer nanocomposites ; free volume ; Kemiteknik och kemisk teknologi; Makromolekylär kemi;

   Sammanfattning : The free volume in polymers is coupled to several important physical properties, such as density, viscosity and gas diffusivity. The physical properties of polymers close to a solid surface have been shown to be significantly perturbed as compared to their bulk state. LÄS MER

3. 7. Controlled Degradation of Polyester-Ethers Revealed by Mass Spectrometry Techniques

   Författare :Anders Höglund; Ann-Christine Albertsson; Jukka Seppälä; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Degradation products; biocompatibility; -caprolactone; 1; 5-dioxepan-2-one; 6-hydroxyhexanoic acid; 3- 2-hydroxyethoxy propanoic acid; oligomers; Polymer chemistry; Polymerkemi;

   Sammanfattning : The use of degradable biomedical materials in e.g. tissue engineering and controlled drug delivery has changed medical science during recent decades. The key question is to adapt the material with respect to mechanical properties, surface characteristics, and degradation profile to suit its intended application. LÄS MER

4. 8. Protein-Polymer Interaction and Association in Aqueous Solution

   Författare :Malin Jönsson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; Makromolekylär kemi; Macromolecular chemistry; enzymologi; Proteiner; enzymology; Proteins; Aqueous two-phase systems; Monte Carlo Simulations; hydrophobic effect; surface hydrophobicity; plasmid DNA; Protein; polymer;

   Sammanfattning : The aim of this thesis has been to study protein-polymer interaction and association. Two different techniques were used; Monte Carlo simulations were combined with partitioning in polymeric aqueous two-phase systems. Monte Carlo simulations have been used to evaluate the hydrophobic interaction in electrolyte solution. LÄS MER

5. 9. Macromolecular organization of the chikungunya virus replication organelle

   Författare :Timothée Laurent; Lars-Anders Carlson; Richard Lundmark; Alex Evilevitch; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The chikungunya virus is a positive-sense RNA virus responsible for the crippling chikungunya fever. It is transmitted through the bites of two species of mosquitoes: Aedes aegypti and Aedes albopictus. LÄS MER

7. 10. Primary Recovery of Biologically Active Compounds Using Macroporous Monolithic Hydrogels

   Författare :Amro Hanora; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Downstream processing; macroporous; Biologically active compounds; Biotechnology; Läkemedelsteknik och relaterad teknik; Pharmaceutical and related technologies; Polymerteknik; biopolymers; Biokemisk teknik; Polymer technology; Makromolekylär kemi; Biochemical technology; Affinity chromatography; Ion exchange chromatography; Expanded bed adsorption chromatography.; Macromolecular chemistry; High through put screening; lactica acids; Endotoxin; Plasmid DNA; Cryogel columns; Bioteknik;

   Sammanfattning : The completion of sequencing of human and other mammalian genomes opens a new era for drug development. New approaches have been proposed for tackling diseases such as development of small molecule therapies based on understanding of human genome and proteome, new proteinous based therapies, where the therapeutic protein can inhibit or modify a certain metabolic pathway or DNA-based therapies delivering a gene into the cell (e.
