16. Atmospheric corrosion of zinc-aluminum and copper-based alloys in chloride-rich environments : Microstructure, corrosion initiation, patina evolution and metal release
Sammanfattning : Fundamental understanding of atmospheric corrosion mechanisms requires an in-depth understanding on the dynamic interaction between corrosive constituents and metal/alloy surfaces. This doctoral study comprises field and laboratory investigations that assess atmospheric corrosion and metal release processes for two different groups of alloys exposed in chloride-rich environments.

17. High Temperature Corrosion of Stainless Steels - The Effects of Chloride Salts and SO2(g)
Sammanfattning : AbstractThe high corrosion rate of superheaters in waste- and biomass- fired plants is often linked to the presence of alkali chlorides. One way to mitigate the corrosion is to replace the superheater material with more corrosion- resistant materials. Another way is to change the corrosive environment by introducing fuel additives.

18. Toxicoproteomics, from finding molecular targets to evaluating the impact on human health
Sammanfattning : The exposome refers to all exposures, including exposures to chemicals, that an individual may encounter over the whole life, from conception to death, that influence the individual’s health. To date, over 200,000 chemicals have been registered under the legislative framework of the European Union. LÄS MER
19. Aetiology and prognosis of paediatric inflammatory bowel disease
Sammanfattning : The incidence rates of childhood-onset inflammatory bowel disease (IBD) have increased worldwide during recent decades. The changing incidence rates of paediatric IBD underscore the importance of early environmental exposures in the pathogenesis of the disease. LÄS MER
20. Superheater corrosion in biomass and waste fired boilers : Characterisation, causes and prevention of chlorine-induced corrosion
Sammanfattning : Biomass and waste fired boilers suffer severely from corrosion of critical components such as superheater tubes. In this work high temperature corrosion of superheater alloys, and methods to mitigate the problem, have been investigated by laboratory studies and controlled field exposures in commercial boilers.
