16. Organic Azides : Functional Molecules and Materials
Abstract : The work presented in this thesis stems from the chemistry of the azido group, and more specifically from the unique reactivity of perfluorinated aromatic azides and how to use this reactivity to access new types of molecules to enable new applications in asymmetric synthesis and materials.In the first section of this thesis, a photoactivatable fluorescence probe is presented, where the non-luminescent azide was activated via a UV-light-promoted intramolecular N–H insertion reaction forming a fluorescence emitter.

17. Nanocellulose and Its Biohybrids for Water Purification : Atomic Force Microscopy as a Tool to Probe Surface Properties and Interactions
Abstract : Nanocellulose has been explored extensively in recent years as an adsorbent due to its promising performance in the removal of charged contaminants from water. In this thesis, various atomic force microscopy (AFM) techniques are used to understand the surface characteristics and specific interactions of nanocellulose with water contaminants (heavy metal ions and dyes) and nanoscale entities (Graphene Oxide (GO) and Graphene Oxide nanocolloids (nanoGO)), and explain the mechanisms related to adsorption, metal ion clustering, self-assembly and mechanical reinforcement.

18. Iridium Catalyzed Carbon- Heteroatom Bond Forming Reactions via Hydrogen Transfer : Method Development and Mechanistic Elucidations
Abstract : The present thesis describes the applicability of two different iridium(III) complexes for C-O and C-N bond forming reactions. The different projects described in this work are united by the use of an iridium catalyst bearing a functionalized N-heterocyclic carbene ligand. READ MORE

19. Material development of a textile bioreactor : All-polyamide composite for the construction of bioreactors
Abstract : Bioreactors are manufactured from stainless/carbon steel, concrete, glass, etc., which are costly and time-consuming to install. Recently, several research studies have been initiated to find cost-efficient materials for constructing bioreactors, one of which is coated textiles. READ MORE

20. Toward Biomass-Derived Recyclable Polyesters
Abstract : Fossil-based plastics have become a matter of concern due to their negative environmental impacts such as greenhouse gas emissions and threats to the health of living beings. Alternative polymers derived from sustainable biomass resources have thus become an attractive research field since the last decade. READ MORE
