1. 1. Hydrogen Bonding in Liquid Alcohols

   Författare :Per Sillrén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrogen Bonded Liquids; Physics of liquids; Diffraction; Monte Carlo Simulation; Alcohols; Neutron Scattering; EPSR;

   Sammanfattning : Hydrogen bonded (H-bonded) materials, such as water, alcohols, sugars, and even DNA, are extremely important for biology, as well as chemical industry. Alcohols are used as solvents in paints, in perfumes, as cleaners, anti-freezers, or as an alternative to petrol in combustion engines. LÄS MER

3. 2. Vitreoscilla Haemoglobin - Peroxidase Activity and Metabolic Aspects

   Författare :Malin Kvist; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; Natural science; lipid peroxidation; hypoxia; salt stress; Escherichia coli; Lactococcus lactis; hydrogen-bonding network; proximal site; mutations; Vitreoscilla haemoglobin; peroxidase activity; Proteins; enzymology; Proteiner; enzymologi;

   Sammanfattning : The function of non-vertebrate haemoglobins (Hbs) appears more diverse than that of vertebrate Hbs, possibly reflecting the various demands to be met among their hosts. Sharing structural features with other haem proteins/enzymes, Hbs display a qualitative overlap in activities with functions extending beyond oxygen transport/storage. LÄS MER

4. 3. Molecular Interaction in Aqueous Solutions : Effects of Temperature and Solutes on Surface Structure and Hydrogen Bonding in Water

   Författare :Clara-Magdalena Saak; Carl Caleman; Olle Björneholm; Nicusor Timneanu; Edwin Kukk; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Intermolecular forces in liquids can give rise to complex emergent structures, particularly in water, where hydrogen bonding causes the formation of extended networks, and surfaces, where intermolecular structures can be distinctly different from the bulk, leading to unique properties and behaviours. While such structures have been studied in detail, it is still relatively unknown how such structures respond and adapt to external changes to their environment. LÄS MER

5. 4. Studies of carbohydrate structure, properties and interactions by nmr spectroscopy

   Författare :Eric Morssing Vilén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In this thesis the structure, properties and interactions of different types of carbohydrates were investigated by NMR spectroscopy. The structures of kappa- (κ) and kappa/mu- (κ/μ) carrageenan oligosaccharides were analyzed by studying the hydroxy protons. LÄS MER

7. 5. Escape from the cage: Ultrafast structural dynamics of photodissociation reactions observed with X-ray solution scattering

   Författare :Amke Nimmrich; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The environment of a molecule is known to greatly impact the course of a reaction. Such an environment can, for instance, be the solvent in a solution phase reaction or the amino acid residues surrounding a chromophore in photoreceptor proteins. LÄS MER
