Cyclic Carbonates Synthesis via Catalytic Cycloaddition of Carbon Dioxide and Epoxides using Sustainable Metal-based Catalysts and Organocatalytic Systems

Feda'a Al-Qaisi

The conversion of carbon dioxide (CO2), an abundant renewable carbon reagent, into cyclic carbonate is of academic and industrial interest. Cyclic carbonate serve as green solvent and have some outstanding properties such as a high boiling point and low toxicity. Titanium and iron would be attractive metal candidates as benign and efficient alternative to other metal catalysis for CO2 co...

Disease dynamics, invasion and biological control of environmentally growing pathogens

Ilona Merikanto

Many existing and emerging microbial infectious diseases are caused by environmentally growing opportunist pathogens. These pathogens are, contrary to obligatory pathogens, able to survive and replicate in the outside-host environment as free-living microbes that use within-host growth as an alternative replication strategy. This disease class has eco-evolutionary implications in natural...

Interactions between quasiregular- and BLD-mappings

Rami Luisto

In this dissertation we study the theory of quasiregular- and BLD-mappings. The unifying theme of the dissertation is how results and techniques used in the study of one of these classes gives rise to ideas in the theory of the other. The first paper in the thesis concerns the theory of quasiregular mappings, which are non-homeomorphic generalizations of quasiconformal mappings; heuristi...
