  2. 11. Fast Dynamic Processes in Solution Studied by NMR Spectroscopy

    Author : Mária Šoltésová; Jozef Kowalewski; Jan Lang; Gyula Batta; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear magnetic resonance; Dynamics; Ethanol; Cryptophanes; Saccharides; Nukleární magnetická rezonance; dynamika; ethanol; kryptofan; sacharidy; fysikalisk kemi; Physical Chemistry;

    Abstract : Nuclear magnetic resonance (NMR) spectroscopy is capable to deliver a detailed information about the dynamics on molecular level in a wide range of time scales, especially if accompanied by suitably chosen theoretical tools. In this work, we employed a set of high-resolution NMR techniques to investigate dynamics processes in several weakly interacting molecular systems in solution. READ MORE

  4. 12. Quantitative Magnetic Resonance in Diffuse Neurological and Liver Disease

    Author : Olof Dahlqvist Leinhard; Peter Lundberg; Anne-Marie Landtblom; Marcel Warntjes; Eva Lund; Göran Starck; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiological physics; Radiofysik;

    Abstract : Introduction: Magnetic resonance (MR) imaging is one of the most important diagnostic tools in modern medicine. Compared to other imaging modalities, it provides superior soft tissue contrast of all parts of the body and it is considered to be safe for patients. READ MORE

  5. 13. Physico-chemical characterisation of novel surfactants

    Author : Britta M. Folmer; KTH; []
    Keywords : Natural raw materials; novel hydrophobes; physico-chemical characterisation; micelles; interfacial adsorption; liquid crystals; enzymes; polymers; complex formation; foam;

    Abstract : The aim of this thesis has been to investigate thephysico-chemical behaviour of novel surfactants based onnatural raw materials. Micellization properties, adsorptionatinterfaces and dynamic aspects have been studied. In additioncomplex formation of surfactants with enzymes and polymers hasbeen evaluated. READ MORE

  6. 14. Development of new NMR techniques and the structure of the N-terminal domain of Escherichia coli DnaB helicas

    Author : Johan Weigelt; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NMR spectroscopy; DnaB; helicase;

    Abstract : New techniques applicable in biomolecular nuclear magnetic resonance (NMR) spectroscopy were developed. The three-dimensional structure of the N-terminal domain of Escherichia coli DnaB helicase was determined at atomic resolution using heteronuclear multidimensional NMR techniques. READ MORE

  7. 15. Staling and Starch Retrogradation in Speciality Bread

    Author : Jeanette Purhagen; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anti-staling agents; Staling; Starch retrogradation; Bread; Water content; Bran; Heat-treated additives; Gluten-free bread;

    Abstract : Bread products are one of the most common and important foods in our daily diet, and have been since ancient times. Although it has a long history and comes in many variations, the staling phenomenon of bread is still not fully known. READ MORE
