1. Humectants and skin : effects of hydration from molecule to man
Abstract : Humectants belong to a group of hydrophilic compounds frequently used in skin care products with the aim to diminish the clinical symptom of skin dryness. The biochemical and biophysical mechanisms by which humectants interact with the skin barrier are far from fully understood. READ MORE

2. Water and alkali salts in the hydrating and hardened green cement-based materials: Hydration process, moisture content and transport
Abstract : Reducing CO2 emissions in the production of cementitious binder is the most effective way to decrease the environmental impact of the construction industry, so a large amount of supplementary cementitious materials (SCMs) has been used in the green concrete. Both the SCMs and alkali salts in binders influence the hydration process and the structure in hardened cement-based materials. READ MORE

3. Hydration, pore structure, and related moisture properties of fly ash blended cement-based materials : Experimental methods and laboratory measurements
Abstract : Cement-based materials, such as mortar and concrete, are the most employed construction materials in the world. Cement is an important component; it reacts with water to form a glue, called cement paste, which causes the material to harden. Today, cement production accounts for a significant portion of the world’s annual carbon dioxide emissions. READ MORE

4. Foreign molecules in biomembranes : Molecular effects on intact stratum corneum and model lipid systems
Abstract : This thesis mainly explores how the molecular mobility of lipid and protein components in the outermost layer of the skin, the stratum corneum (SC), varies with different conditions and upon adding foreign compounds. These studies require methods that makes it possible to detect and characterize the minor amount of fluid components in the highly ordered solid SC sample with resolved molecular information.

5. Structure and dynamics of complex materials in the water-poor regime
Abstract : In the solid state, molecules are normally ordered in a specific structure. With time, and as a result of influence from the surroundings, solid materials can change their molecular and/or crystal structure and, as a consequence, obtain completely different properties. Water is particularly important in this respect. READ MORE
