16. Behavioural Atmospheres and Vagueness in the Sharing of Urban Public Places
Sammanfattning : This thesis is an exploration of urban public places and social interactions understood as a sharing of place. Against the background of urbanization, migration, urban densification and new technologies, it can be assumed that our everyday ways of sharing place with one another are becoming more diversified.

17. Oxidation of Fe- and Ni-aluminides in Dry and Humid Atmospheres
Sammanfattning : Aluminides based on Ni3Al and Fe3Al offer good mechanical and corrosion properties at high temperatures and are therefore being considered in the automotive and chemical industries. The aim of this work was to study the early stages and the mechanisms of oxide growth on unalloyed Ni3Al and Fe3Al in air. LÄS MER
18. Investigation of the behaviour of gaseous I2 and RuO4 in different atmospheres
Sammanfattning : During a severe accident several hazardous and radiotoxic fission products can be released and constitute a threat to the environment. Two of the most important fission products are iodine and ruthenium which will be accumulated after inhalation in the human body in the thyroid gland and in the respiratory organs, respectively.

20. Synthesis of complex organics via molecular growth mechanisms : Combined experimental and theoretical studies on ion-neutral reactions of C2H2N+ with ubiquitous hydrocarbons in Titan's ionosphere
Sammanfattning : To provide insights on the molecular growth mechanisms leading to large carbon and nitrogen-bearing species in Titan’s ionosphere, laboratory measurements of ion-neutral reactions were conducted and the results are presented in the following doctoral dissertation. The product ions of the C2H2N+ reactions with saturated and unsaturated neutral hydrocarbons have been investigated using Guided Ion Beam Mass Spectrometer (GIB-MS). LÄS MER
