1. A surface approach to understanding the dissolution of fluorite type materials : Implications for mineral dissolution kinetic models
Sammanfattning : Traditional dissolution models are based in the analyses of bulk solution compositions and ignore the fact that different sites of a surface dissolve at different rates. Consequently, the variation of surface area and surface reactivity during dissolution are not considered for the calculation of the overall dissolution rate, which is expected to remain constant with time.

2. Radiation Induced Oxidative Dissolution of UO2
Sammanfattning : Sammanfattning Denna doktorsavhandling berör oxidativ upplösning av UO2 (som modellsubstans för utbränt kärnbränsle) orsakad av radiolys av vatten samt effekten av H2 på denna denna process. Hastighetskonstanter för oxidation av UO2-pulver med olika oxidanter såsom H2O2 har bestämts experimentellt. LÄS MER
3. Dissolution of cellulose for textile fibre applications
Sammanfattning : This thesis forms part of a project with the objective of developing and implementing a novel, wood-based, process for the industrial production of cellulose textile fibres. This new process should not only be cost effective but also have far less environmental impact then current processes. LÄS MER
4. Carbohydrate degradation and dissolution during Kraft cooking : Modelling of kinetic results
Sammanfattning : Chemical pulp fibres from wood are commonly used in products associated with packaging as well as with printing and writing. The prevalent way of liberating fibres is by subjecting wood chips to Kraft cooking. This process has a history of almost 130 years and should be both well described and well established. LÄS MER
5. Mechanistic Modelling of Drug Dissolution and Matrix Formulations: Rotating Disc Dissolution, Dissolution in a Stagnant Medium, Swelling and Dissolving Matrix Systems
Sammanfattning : Popular Abstract in Swedish Under årens lopp har människan gjort stora landvinningar inom läkemedelsforskning, vilket har lett fram till avancerade läkemedel som idag tas för givna. Avancerade läkemedel sätter dock höga krav på tillverkarna av läkemedel, vilket har lett till att framtagandet av nya läkemedel är en ganska komplicerad process. LÄS MER
