1. A Microcalorimetric Study of Macrocyclic Complexes in Aqueous Solution
Sammanfattning : The present work involves a microcalorimetric characterization of the interactions among macrocyclic compounds and aliphatic molecules in aqueous solution. The macrocyclic compounds used in the study are a-,b- and g-cyclodextrin and 25,26,27,28-tetrahydroxycalix[4]arene-5,11,17,23- tetrasulphonate. LÄS MER
2. Ozone chemistry in aqueous solution : ozone decomposition and stabilisation
Sammanfattning : Ozone is used in many applications in the industry as an oxidising agent for example for bleaching and sterilisation. The decomposition of ozone in aqueous solutions is complex, and is affected by many properties such as, pH, temperature and substances present in the water. LÄS MER
3. Amphiphilic Molecules in Aqueous Solution
Sammanfattning : The aim of this thesis was to investigate amphiphilic molecules in aqueous solution. The work was divided into two parts. In the first part the effects of different counterions on phase behavior was investigated, while the second part concerns the 1-monooleoyl-rac-glycerol (MO)/n-octyl-β-D-glucoside (OG)/2H2O-system.

4. Modeling of inorganic ions in aqueous solution
Sammanfattning : Essentially all chemical processes and reactions occurring in the environment take place in the presence of ions. In water, ions set the conditions for how other dissolved particles interact. Ions are also directly involved in chemical reactions affecting the climate such as ozone depletion. LÄS MER
5. Cellulose solutions in aqueous hydroxide bases
Sammanfattning : Cellulose is a renewable and widely available carbohydrate polymer whose utility for mankind only increases as we move towards a circular bioeconomy. Unlike most plastics or metals, it cannot be melted, and therefore, solution processing is important. LÄS MER
