2. 1. Microgels as drug delivery vehicles : loading and release of amphiphilic drugs

   Author : Yassir Al-Tikriti; Per Hansson; Magnus Bergström; Matthew Libera; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microgel; amphiphilic drug; phase separation; micropipette; Raman microscopy; controlled release; drug delivery; SAXS; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

   Abstract : Polyelectrolyte microgels are used as delivery vehicles for amphiphilic drugs in, e.g., treatments of liver cancer by a method called trans-arterial chemoembolization. READ MORE

4. 2. Amphiphilic hydrogels functionalized with antimicrobial peptides for wound care

   Author : Edvin Blomstrand; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; infections; Antimicrobial peptides; hydrogels; wound care; lyotropic liquid crystals; antibacterial surfaces; amphiphilic polymers; surface functionalization;

   Abstract : Bacteria have the potential to cause significant harm to us when found in places where we do not want them, such as in wounds. Through the last century, the gold standard of eradicating bacteria in these cases has been with antibiotics. READ MORE

5. 3. Properties of Asphaltenes with emphasis on NMR self-diffusion as the investigating technique

   Author : Jenny-Ann Östlund; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; amphiphilic; diffusion; oil; mixture analysis; CORE; stability; NMR; pulsed gradient spin echo; light scattering; XPS; asphaltene; chemical interactions;

   Abstract : Asphaltenes are high-molecular weight, highly aromatic molecules that have a strong tendency to aggregate. Asphaltenes are found in oil and may, if they form particles, cause problems during oil production and handling. READ MORE

6. 4. Phosphine ligands with triamine functionality - preparation and application in catalysis

   Author : Magnus Karlsson; Enheten för fysikalisk och teoretisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; water soluble; palladium; amphiphilic; rhodium; Oorganisk kemi;

   Abstract : Incorporation of the triamine, bis(2-diethylaminoethyl) amine as a side chain substituent on triphenylphosphine, (2S,4S)-4-diphenylphosphino-2-diphenylphosphino-methylpyrrolidine (PPM) or (R,R)-3,4-bis(diphenylphosphin)pyrrolidine (Pyrphos) gives the three new amphiphilic ligands N3P, N3PPM and N3-Pyrphos respectively. Because of the triamine functionality the distribution of the ligands and their complexes between water and an organic solvent is controlled by the pH of the aqueous phase. READ MORE

7. 5. Amphiphilic Molecules in Aqueous Solution

   Author : Gerd Persson; Göran Lindblom; Håkan Edlund; Björn Lindman; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; liquid crystal; phase diagrams; counterions; alkylpyridinium octanesulfonates; 1-monooleoyl-rac-glycerol; n-octyl-β-D-glucoside; cubic phases; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

   Abstract : The aim of this thesis was to investigate amphiphilic molecules in aqueous solution. The work was divided into two parts. In the first part the effects of different counterions on phase behavior was investigated, while the second part concerns the 1-monooleoyl-rac-glycerol (MO)/n-octyl-β-D-glucoside (OG)/2H2O-system.
