1. Effects of polymeric surfactants on the crystallisation of inorganic materials
Sammanfattning : This thesis concerns effects of polymeric surfactants on the crystal growth of inorganic structures. The crystal growth of calcium carbonate on steel surfaces was studied with a heat exchanger cell and with an electrochemical method. LÄS MER
2. Self-Assembling Surfactant Aggregates for Synthesis of Nanomaterials
Sammanfattning : The main objective of this thesis was to study how surfactant assemblies can be used as templates to form inorganic nanomaterials. Both water-in-oil microemulsions and liquid crystalline phases have been used as structure directing agents. LÄS MER
3. Disintegration of Lime Mud Particles during the Causticizing Operation
Sammanfattning : It is of essential importance that the white liquor used in processing wood chips to produce pulp in the sulphate pulp process is of high and uniform quality. The white liquor is, together with lime mud, produced in the causticizing plant where sodium carbonate is causticized with lime, slaked in green liquor. LÄS MER
4. Experimental, petrological and geochemical investigations of ikaite (CaCO3·6H2O) formation in marine environments
Sammanfattning : Carbonates are a group of minerals that play an essential role in several processes on planet Earth, for example in the global carbon cycle and as a product of biomineralisation. Calcite (CaCO3) is by far the most common mineral in the carbonate group, and the stable form of carbonate at Earth surface conditions. LÄS MER
5. Understanding Physical Reality via Virtual Experiments
Sammanfattning : In this thesis I have studied some problems of condensed matter at high pressures and temperatures by means of numerical simulations based on Density Functional Theory (DFT).The stability of MgCO3 and CaCO3 carbonates at the Earth's mantle conditions may play an important role in the global carbon cycle through the subduction of the oceanic crust.
