1. Dynamics of Enzyme Immobilization in Mesoporous Silica Particles
Sammanfattning : The focus of this thesis is placed on the dynamic behavior of proteins in confining environments which is studied as a scientific challenge for a deeper understanding of the immobilization mechanism and a better designing of enzyme immobilization in porous materials. Enzymes are immobilized in porous materials to improve the enzyme activity and simplify their purification from the product solution in biocatalytic applications. LÄS MER
2. Foam modeling including pore gas interaction for crashworthiness analysis
Sammanfattning : Foams are used in vehicles for three main functions: enhancing comfort, e.g.soft foams used in seats cushions, energy absorbtion, e.g. LÄS MER
3. Water and alkali salts in the hydrating and hardened green cement-based materials: Hydration process, moisture content and transport
Sammanfattning : 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. LÄS MER
4. Structure of Hardened Cement-Fly Ash Systems and Their Related Properties
Sammanfattning : The influence of fly ash on the pore structure and microstructure of cement paste and mortar has been investigated. The methods applied include water vapour sorption isotherms, scanning electron microscopy, X-ray diffraction analysis and thermogravity/differential thermal analysis. LÄS MER
5. In Situ Stress Conditions Across Clay Slopes. A Study Comprising Seven Test Sites
Sammanfattning : The in situ stress conditions in clay slopes differ mainly depending on the stability of the slope, the soil properties, the pore pressure situation and also on which part of the slope is studied. The objective of the study is to investigate the in situ stress conditions in slopes and how they vary with seasonal variations in pore pressures and external loading conditions, such as the excavation and filling of earth material.
