1. Iridium-Catalyzed C−H Activation Methods for Late-Stage Functionalization of Pharmaceuticals
Abstract : C-H activations have over the recent decades risen from a mere curiosity to a viable synthetic strategy. However, challenges in terms of accessible transformations, selectivity and functional group tolerance limit the widespread applicability of this approach. READ MORE

2. Dynamic modelling of the forest ecosystem: Incorporation of the phosphorus cycle
Abstract : The forest ecosystem provides and regulates many important ecosystem services, such as soil and water protection, timber production, and climate regulation. It has been influenced by changes induced by humans, for example, our increasing demand for timber and bioenergy, the increase in nitrogen (N) deposition and CO2 concentrations due to industrialization, and climate change which has caused an increase in global temperature and extreme events such as storms.

3. Degradation of polyethylene pipes distributing chlorinated water : depletion of stabilizers, release of degraded products and polymer degradation
Abstract : This thesis presents the study of antioxidants depletions in chlorinated media (10 ppm Cl2 - and ClO2 - aqueous media), polyethylene pipes degradations scenarios and migration of the degraded species to aqueous phase. Pressure testing on pipes and squalane testing with controlled pH aqueous media (6.8 ± 0. READ MORE

5. The Littorina transgression in southeastern Sweden and its relation to mid-Holocene climate variability
Abstract : Lateglacial and Holocene shoreline displacement along the Baltic coast resulted from both the isostatic land uplift and the ice-volume-equivalent sea-level rise. Relative changes of these two components led to alternating contact/isolation of the Baltic Basin with the North Sea during the Holocene. READ MORE
