2. 1. Foreign molecules in biomembranes : Molecular effects on intact stratum corneum and model lipid systems

   Author : Quoc Dat Pham; Fysikalisk kemi; []
   Keywords : stratum corneum; lipid; keratin filament; protein; DMPC; penetration enhancer; osmolyte; solvent; monoterpene; fatty acid; hydration; molecular mobility; fluidity; permeability; PT ssNMR; diffusion cell;

   Abstract : This thesis mainly explores how the molecular mobility of lipid and protein components in the outermost layer of the skin, the stratum corneum (SC), varies with different conditions and upon adding foreign compounds. These studies require methods that makes it possible to detect and characterize the minor amount of fluid components in the highly ordered solid SC sample with resolved molecular information.

4. 2. Binary mixtures and cationic modification of protic ionic liquids. Local structure and transport properties

   Author : Iqbaal Abdurrokhman; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nuclear magnetic spectroscopy; cationic modification; triazolium; imidazolium; proton mobility; Protic ionic liquids; vibrational spectroscopy; impedance spectroscopy; binary mixtures; synthesis;

   Abstract : Protic ionic liquids are a subclass of ionic liquids, which in many cases are obtained by mixing an equimolar amount of Brønsted acid and base. Protic ionic liquids possess an exchangeable proton that gives them distinct features, e.g. READ MORE

5. 3. Molecular structure, interactions, and dynamics of novel Li-battery electrolytes

   Author : Luis Aguilera Medina; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAXS; Raman scattering; imidazolium; NSE; lithium ion battery; electrolyte; organic solvent; pyrrolidinium; TFSI; ionic liquid;

   Abstract : Lithium-ion batteries are one of the most promising candidates for energy storage in sustainable technologies such as electro-mobility or renewable energy systems. However, at present they are incapable to compete with the combustion engine to power vehicles in terms of capacity, price, and safety. READ MORE

6. 4. Fatty acid methyl esters as reactive diluents in solvent-borne thermally cured coil-coatings

   Author : Katarina Johansson; Mats Johansson; Mats Jonsson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fatty acids; Reactive diluents; Coatings; Thermal curing; Transesterification; Film properties; Polymer chemistry; Polymerkemi;

   Abstract : This work describes how a fatty acid methyl ester (FAME) derived from a vegetable oil can be introduced as reactive diluent in a solvent-borne thermally cured coil-coating system. The evaluated reactive diluent, rape seed methyl ester (RME), has been evaluated both in a fully formulated clear coat system and via model studies. READ MORE

7. 5. Amphiphilic Graft Copolymer Electrolytes for Lithium-Ion Polymer Batteries. - Preparation and Characterisation

   Author : Patrik Gavelin; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; biopolymers; Polymerteknik; Kemiteknik och kemisk teknologi; Chemical technology and engineering; transport dynamics; ion conductivity; solid polymer electrolyte; gel electrolyte; macromonomer copolymerization; amphiphilic graft copolymer;

   Abstract : In the present work amphiphilic graft copolymers were prepared by free radical copolymerization of macromonomers in solution. The graft copolymers consisted of methacrylate backbones bearing ethylene oxide (EO)n side chains of varying length as ionophilic groups, and fluorocarbon (CF2)6 side chains or hydrocarbon groups as ionophobic groups.
