1. Nanotribology, Surface Interactions and Characterization : An AFM Study
Sammanfattning : When two surfaces achieve contact, then contact phenomena such as adhesion, friction and wear can occur, which are of great interest in many disciplines, including physics, physical chemistry, material chemistry, and life and health sciences. These phenomena are largely determined by the nature and magnitude of the surface forces such as van der Waals, capillary and hydration forces. LÄS MER
2. Interfacial and material aspects of powders with relevance to pharmaceutical tableting performance
Sammanfattning : Tablets are the most common forms of drug administration. They are convenient to administer and easy to manufacture. However, problems associated with the adhesion of the powders to the tableting tools are common. This phenomenon is known as sticking and even though it has been well documented and studied, it remains poorly understood. LÄS MER
3. Fatty Acid Self-Assembly at the Air–Water Interface : Curvature, Patterning, and Biomimetics: A Study by Neutron Reflectometry and Atomic Force Microscopy
Sammanfattning : For more than a hundred years of interfacial science, long chain fatty acids have been the primary system for the study of floating monolayers at the air–water interface due to their amphiphilic nature and system simplicity: an insoluble hydrocarbon chain and a soluble carboxyl group at a flat air–water interface. Despite―or perhaps rather due to―the assumed simplicity of such systems and the maturity of the research field, the seemingly fundamentally rooted notion of a two-dimensional water surface has yet to be challenged.

4. Adsorption of molecular thin films on metal and metal oxide surfaces
Sammanfattning : Metal and metal oxides are widely used in industry, and to optimize their performance their surfaces are commonly functionalized by the formation of thin films. Self-assembled monolayers (SAMs) are deposited on metals or metal oxides either from solution or by gas deposition. LÄS MER
5. On the structure and mechanical properties of in vitro salivary pellicles
Sammanfattning : Salivary pellicles display exceptional hydration and lubrication performance. At present, there are still gaps in the understanding of how this is achieved. LÄS MER
