1. Amorphous magnesium carbonate nanomaterials : Synthesis, characterization and applications
Sammanfattning : High surface-to-volume ratio materials, including nanoparticles and mesoporous materials, have a number of applications due to their large surface area and special structures. Traditional approaches for synthesizing high surface-to-volume ratio nanomaterials are often complicated, expensive or environmentally unfriendly. LÄS MER
2. Metal Hydrogen Interaction and Structural Characterization of Amorphous Materials from first principles
Sammanfattning : In this thesis, first-principles calculations based on density functional theory have been employed to investigate metal hydrogen interaction in transition, p-block and rare earth metals. Furthermore, the accuracy of the stochastic quenching method was tested in describing the structure of amorphous Fe(1-x)Zrx. LÄS MER
3. Transmission Electron Microscopy for Characterization of Structures, Interfaces and Magnetic Moments in Magnetic Thin Films and Multilayers
Sammanfattning : Structural characterization is essential for the understanding of the magnetic properties of thin films and multilayers. In this thesis, both crystalline and amorphous thin films and multilayers were analyzed utilizing transmission electron microscopy (TEM). LÄS MER
4. Crystallization in additive manufacturing of metallic glass
Sammanfattning : Metallic glasses are non-crystalline metals that are obtained by rapid cooling of the melt to bypass crystallization. The amorphous atomic structure shows enhanced properties relative to the crystalline counterpart. For example, enhanced mechanical properties, improved corrosion resistance, as well as excellent soft magnetic properties. LÄS MER
5. On-site wastewater treatment : Polonite and other filter materials for removal of metals, nitrogen and phosphorus
Sammanfattning : Bed filters using reactive materials are an emerging technology for on-site wastewater treatment. Chemical reactions transfer contaminants from the aqueous to the solid phase. Phosphorus is removed from domestic wastewater by sorption to filter materials, which can then be recycled to agriculture as fertilisers and soil amendments. LÄS MER
