1. 1. Solid-State NMR Characterization of Lipid Membranes

   Författare :Vasco Castro; Arnold Maliniak; Göran Lindblom; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid-State NMR; Membranes; Lipids; Glycolipids; Local Anesthetics; Hydration; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

   Sammanfattning : This thesis deals with the study of lipid bilayer systems by solid-state nuclear magnetic resonance. Two-dimensional 1H-13C separated local field experiments under magic-angle spinning were employed to investigate structural and dynamical modifications of cell membranes, resulting from the addition of compounds with some biological relevance.

   Sammanfattning : The use of solid polymer electrolytes (SPEs) for lithium battery devices is a rapidly growing research area. The liquid electrolytes that are used today are inflammable and harmful towards the battery components. LÄS MER

7. 5. Microstructure Formation During Solidification and Solid State Transformation in Compacted Graphite Iron

   Författare :Mathias König; Magnus Wessén; Ingvar L. Svensson; Jorge Sikora; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast Iron; CGI; Microstructure Formation; Mechanical Properties; Modelling; Solidification; Solid State Transformation;

   Sammanfattning : Compacted graphite iron (CGI) is rapidly becoming an attractive alternative material for engine components in the automotive industry, replacing lamellar graphite iron (LGI) in applications where high mechanical strength is desired. However, the gain in mechanical strength comes with a cost; thermal conductivity, process control and machining are three areas that are more challenging for CGI. LÄS MER
