Sammanfattning : Structural properties of adsorbed overlayers on well-defined single crystals and of Palladium-Manganese surface alloys formed on Pd(100) have been investigated using synchrotron-based photoemission, scanning tunneling microscopy and Fourier-transform infrared spectroscopy. The experimental valence electronic structure of PdMn systems on Pd(100) is compared to density functional calculations (DFT). LÄS MER
Sammanfattning : In this thesis, quantum-mechanical calculations within density-functional theory on metallic systems are presented. The overarching goal has been to investigate effects of disorder. In particular, one of the properties investigated is the bindingenergy shifts for core electrons in binary alloys using different theoretical methods. LÄS MER
Sammanfattning : One alternative proposed to reduce greenhouse gas emissions is carbon capture and storage, where the carbon dioxide emitted from large point sources is captured, compressed and stored in underground geological formations. Many of the largest point sources of carbon dioxide are power plants and industries fuelled by fossil fuels or biomass. LÄS MER
Sammanfattning : In the modern practice, a sustainable development strategy in a domain of wasteutilization is shifting its focus from a general completeness of recycling to a morespecific attention to efficiently utilize elements in the wastes. This is well-illustrated bythe steelmaking slag industries. LÄS MER
