1. 1. Organic reactions in self-organized surfactant systems

   Författare :Fredrik Currie; Chalmers University of Technology; []
   Nyckelord :organic synthesis; kinetics; micelle; regioselectivity; microemulsion;

   Sammanfattning : The aim of this work has been to investigate how microemulsions and micellar systems can be used as reaction media to overcome reactant incompatibility, enhance reaction rates and especially to control product composition, i.e., introducing regioselectivity, in organic synthesis.

3. 2. Interaction between Crosslinked Polyelectrolyte Gels and Oppositely Charged Surfactants

   Författare :Peter Nilsson; Per Hansson; Ksenija Kogej; Uppsala universitet; []
   Nyckelord :Pharmaceutical chemistry; gel; polyelectrolyte; surfactant; deswelling; kinetics; phase separation; volume transition; ion-exchange; diffusion; liquid crystal; SAXS; cubic Pm3n; Farmaceutisk kemi;

   Sammanfattning : The interactions between anionic, crosslinked gels and cationic surfactants have been investigated. When exposed to oppositely charged surfactant, the gel collapses into a dense complex of polyion and micelles. LÄS MER

4. 3. Gas-Phase Protein Structure Under the Computational Microscope : Hydration, Titration, and Temperature

   Författare :Erik Marklund; David van der Spoel; Albert Heck; Uppsala universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Molecular dynamics; gas phase; proteins; micelles; proton transfer; Grothuss mechanism; kinetics; Physics; Fysik; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

   Sammanfattning : Although the native environment of the vast majority of proteins is a complex aqueous solution, like the interior of a cell, many analysis methods for assessing chemical and physical properties of biomolecules require the sample to be aerosolized; that is, transferred to the gas-phase. An important example is electrospray-ionization mass spectrometry, which can provide a wide range of information about e. LÄS MER

7. 5. Organic Synthesis in Nonionic Microemulsions

   Författare :Maria Häger; Chalmers University of Technology; []
   Nyckelord :organic reaction; phase behaviour; microemulsion; reaction kinetics;

   Sammanfattning : The aim of this work has been to explore the use of microemulsions as reaction media for organic synthesis. Another important aim has been to improve the understanding of the reaction kinetics and the mechanism of the reaction in this type of surfactant system. LÄS MER
