1. Poly (3-hydroxybutyrate) from a moderate halophile: production and modification for new applications
Sammanfattning : Polyhydroxybutyrate (PHB) is a homopolymer belonging to the family of biopolyesters, polyhydroxyalkanoates (PHA) produced by different bacteria and archaea as intracellular granules often under conditions of metabolic stress due to a limited supply of essential nutrients. The properties of the PHAs are similar to those of polyethylene and polypropylene and can hence replace these fossil based polymers in a large variety of applications. LÄS MER
2. Ion pairing and Langmuir-like adsorption at aqueous surfaces studied by core-level spectroscopy
Sammanfattning : Surface-bulk equilibria for solutes in aqueous solutions are studied using X-ray Photoelectron Spectroscopy (XPS) with high surface and chemical sensitivity. In the first part, the results show a reduction of the biochemically relevant guanidinium ions’ surface propensity with the addition of disodium sulphate due to ion pairing with the strongly hydrated sulphate ion, which could have implications for protein folding.

3. Models of NADH with C2 and D2 Symmetry
Sammanfattning : A novel supramolecular approach to the design of NADH models is presented in this dissertation. The models can be divided into two types, C2 symmetric and D2 symmetric macrocyclic structures. The C2 symmetric models are made from a chiral C2 symmetric unit, two dihydronicotinamide units and a phenylene spacer, to form a macrocyclic structure. LÄS MER
