2. 1. Enlightening Water : Science, market & regulation of mineral waters in eighteenth-century France

   Author : Armel Cornu; H. Otto Sibum; Hjalmar Fors; Sven Widmalm; Jakob Vogel; Uppsala universitet; []
   Keywords : HUMANIORA; HUMANITIES; Mineral waters; Eighteenth century; French Enlightenment; History of science; History of chemistry; Social history; Société de Médecine; History of Sciences and Ideas; Idé- och lärdomshistoria;

   Abstract : My thesis investigates the process through which French mineral waters were conceptually and materially transformed by the forces of market, regulation, and science during the Enlightenment. Tracing this process deepens current understandings of eighteenth-century societies, and presents a novel image of the development of medicine and chemistry. READ MORE

4. 2. Molecular Arrangement, Electronic Structure and Transport Properties in Surfactant Gel- and Related Systems Studied by Soft X-ray and Dielectric Spectroscopy

   Author : Johan Gråsjö; Maria Strömme; Jan Swenson; Uppsala universitet; []

   Abstract : This thesis concerns studies of aqueous soft matter systems, especially surfactant micelle systems.The aim has been to study the molecular arrangement and electronic structure of the constituents of, as well as transport properties in such a system. READ MORE

5. 3. Molecular structure and dynamics of liquid water : Simulations complementing experiments

   Author : Daniel Schlesinger; Lars G. M. Pettersson; Paola Gallo; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; liquid water; supercooled water; molecular simulation; evaporative cooling; teoretisk fysik; Theoretical Physics;

   Abstract : Water is abundant on earth and in the atmosphere and the most crucial liquid for life as we know it. It has been subject to rather intense research since more than a century and still holds secrets about its molecular structure and dynamics, particularly in the supercooled state, i. e. the metastable liquid below its melting point.

6. 4. Protein-water interactions studied by molecular dynamics simulations

   Author : Filip Persson; Biofysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MD simulations; NMR nuclear magnetic resonance ; MRD; water dynamics; protein dynamics; protein hydration; Amide hydrogen exchange; Internal water; compressibility;

   Abstract : Most proteins have evolved to function optimally in aqueous environments, and the interactions between protein and water therefore play a fundamental role in the stability, dynamics, and function of proteins. Although we understand many details of water, we understand much less about the protein-water interface. READ MORE

7. 5. Nuclear magnetic resonance studies of water self-diffusion in porous systems

   Author : Daniel Topgaard; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion diffraction; nonfreezing; anisotropy; tortuosity; cross relaxation; emulsion; starch; cellulose; porous material; water; NMR; self-diffusion; Physical chemistry; Fysikalisk kemi;

   Abstract : Proton nuclear magnetic resonance (NMR) was used to study the self-diffusion of water in porous systems that respond to a change in water content in order to elucidate the porous structure and the properties of the confined water. In the carbohydrate systems cellulose fibers and starch granules, water is free to move throughout the porous objects, albeit with a rate reduced from the value of the bulk liquid, The reduction is related to the tortuosity of the pore space filled by water.
