1. Structural investigation of Nb-based layer sulfides
Sammanfattning : In this work we have investigated the intercalation of electron-donors between NbS2 slabs in Nb-based layer sulfides.Two series of Sr substituted Nb-based misfit sulfides belonging to the 1.5Q/1H and 1Q/1H series of misfit layer compounds have been synthesised. LÄS MER
2. Quantification of mineral weathering rates in sulfidic mine tailings under water-saturated conditions
Sammanfattning : Tailings are a fine-grained waste product produced during the metal recovery process. Tailings consist mostly of different silicates but also sulfides (e.g. pyrite), since 100 % metal recovery is not possible. LÄS MER
3. A Study of Slag/Metal Equilibrium and Inclusion Characteristics during Ladle Treatment and after Ingot Casting
Sammanfattning : Today, there is a high demand on clean steel for high performance materialproperties. Thus, steel producers try to deliver a steel product with the highestquality and cleanliness to the market. The number of parameters that affect thesteel cleanliness may vary depending on the required material properties of thefinal product. LÄS MER
4. Chemical and mechanical behaviour of some sulfides during metamorphism
Sammanfattning : .... LÄS MER
5. Triboactive Low-Friction Coatings Based on Sulfides and Carbides
Sammanfattning : For sustainable development, it is highly important to limit the loss of energy and materials in machines used for transportation, manufacturing, and other purposes. Large improvements can be achieved by reducing friction and wear in machine elements, for example by the application of coatings. LÄS MER
