1. Atomic Scale Degradation of Zirconium Alloys for Nuclear Applications
Sammanfattning : Due to their low thermal neutron capture cross-section, zirconium alloys are widely used in the nuclear industry as fuel cladding and for structural components. The lifetime of the fuel assemblies in the reactors is primarily dictated by the ability of the cladding to withstand oxidation and hydrogen pick-up from the coolant water and radiation damage induced by the neutron flux.

2. Relict non-glacial surfaces and autochthonous blockfields in the northern Swedish mountains
Sammanfattning : Relict non-glacial surfaces occur in many formerly glaciated landscapes, where they represent areas that have escaped significant glacial modification. Frequently distinguished by blockfield mantles, relict non-glacial surfaces are important archives of long-term weathering and landscape evolution processes. LÄS MER
3. Health costs of particle emissions : economic valuation of increased mortality due to exhaust emissions of fine particles
Sammanfattning : .... LÄS MER
4. Palaeoglaciology of the northeastern Tibetan Plateau
Sammanfattning : This study concerns the palaeoglaciation of the northeastern Tibetan Plateau, with emphasis on the Bayan Har Shan (Shan = Mountain) in the headwaters of Huang He (Yellow River). To reconstruct past glacier development multiple techniques, including remote sensing, field investigations, cosmogenic exposure dating, and numerical modelling have been employed. LÄS MER
5. The Formation and Breakdown of Passive Film on Ni Alloys : in situ synchrotron studies
Sammanfattning : Corrosion results in huge annual costs and a large environmental footprint. The corrosion rate of some alloys can be made negligible by the presence of a spontaneously forming oxide film on the surface, a so-called passive film. Famous examples of alloys exhibiting passivity are stainless steels. LÄS MER
