Sammanfattning : Colloidal dispersions and gels are important material systems with applications in many industrial processes and consumer products. This thesis aims at increasing the understanding of colloidal interactions and the phase transition from a colloidal dispersion to an arrested structure in two systems based on silica. LÄS MER
2. Rechargeable Aqueous Batteries Based on Available Resources Investigation and Development towards Efficient Battery PerformanceDetta är en avhandling från Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University
Sammanfattning : Batteries employing water based electrolytes enable extremely low manufacturing costs and are inherently safer than Li-ion batteries. Batteries based on zinc, manganese dioxide, iron, and air have high energy relevancy, are not resource restricted, and can contribute to large scale energy storage solutions. LÄS MER
- Detta är en avhandling från Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University
Sammanfattning : This thesis deal with the sol-gel transition of two quite different systems, both based on silica. The overall aim is to understand what interactions lead to this sol-gel transition and how the structure and dynamics change as a result of this.The ﬁrst project concern the gelation of water glass, also known as alkaline sodium silicate solutions.

4. On the bone response to oxidized titanium implants. The role of microporous structure and chemical composition of the surface oxide in enhanced osseointegrationDetta är en avhandling från Göteborg
Sammanfattning : Background: Titanium implants have been widely used clinically for various types of bone-anchored reconstructions. A thin native oxide film, naturally formed on titanium implants contacts with bone tissue and has been considered to be of great importance for successful osseointegration. LÄS MER
5. Towards alkali-stable polymers and hydroxide exchange membranes functionalized with alicyclic quaternary ammonium cationsDetta är en avhandling från Centre for Analysis and Synthesis, Department of Chemistry, Lund University
Sammanfattning : In the current work, cationic polymers functionalized with N-alicyclic quaternary ammonium (QA) cations were synthesized and characterized as potential hydroxide exchange membranes (HEMs) for application in fuel cells. Three different polymers, namely poly(arylene ether sulfone), spiro-ionene and poly(arylene alkylene), were explored as polymer backbones for the HEMs. LÄS MER
