6. The Bentonite Barrier - Swelling Properties, Redox Chemistry and Mineral Evolution
Sammanfattning : Bentonite is planned for use as a buffer material in high-level radioactive waste repositories, where safety assessment is performed for very long periods (100-1000 ka). This thesis focuses on the swelling of smectites in liquid water, and analysis of bentonite from field experiments at Äspö Hard Rock Laboratory, Sweden. LÄS MER
7. Improving selectivity in protein extraction by subtle interactions and environmental changes
Sammanfattning : The challenges for efficient bioprocesses lie in developing and adapting further current technologies or in creating innovative separation technologies. The thesis is based on the studies on protein recovery from crude feedstocks by extraction in aqueous two-phase systems and detergent foam, respectively. LÄS MER
8. Structural Studies of Oligo(ethylene glycol)-Containing Assemblies on Gold
Sammanfattning : The work presents in this thesis has been focused on structural characterization of a series of selected well-defined molecular architectures for the application as biomimetic membranes. The molecular architectures were prepared by self-assembly from dilute solution onto gold substrates, so called self-assembled monolayers (SAMs). LÄS MER
9. Tailoring Cellulose Nanofibrils for Advanced Materials
Sammanfattning : Cellulose nanofibrils (CNFs) are nanoscale fibers of high aspect ratio that can be isolated from a wide variety of cellulosic sources, including wood and bacterial cellulose. With high strength despite of their low density, CNFs are a promising renewable building block for the preparation of nanostructured materials and composites. LÄS MER
10. FACING THE CHALLENGE OF SKIN PENETRATION - A STUDY ON LIPIDIC LIQUID CRYSTALLINE PHASES FOR DERMAL DRUG DELIVERY
Sammanfattning : The skin is a barrier which protects us against daily attacks of foreign substances. From a pharmaceutical perspective it is also an interesting delivery route with its large surface and possibility to reach the blood stream circumventing first passage metabolism. With the varied size, structure etc. LÄS MER
