Sammanfattning : This thesis is divided in four chapters, containing the work realised in two universities and has as the aim the synthesis of nitrogen-containing compounds. The first chapter describes the project realised at The University of Sheffield. LÄS MER
2. Carbohydrate-Functionalized Nanomaterials : Synthesis, Characterization and Biorecognition Studies
Sammanfattning : This thesis focuses on the development of carbohydrate coupling chemistry on nanomaterials and their biological activity studies. It is divided into two parts:In part one, two carbohydrate immobilization approaches, based on perfluorophenyl azide (PFPA)-functionalized silica nanoparticles (SNPs), are presented, where the binding affinity of the glyconanoparticles was evaluated through carbohydrate-lectin interaction.

3. Laccase from a Litter Degrading Fungus: Evaluation for Environmental Applications and Modification of Lignin to a Bioadhesive
Sammanfattning : Laccase, the phenol oxidizing enzyme, was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes single electron transfer oxidation in the presence of molecular oxygen producing water as by-product.

Sammanfattning : Microporous organic polymers (MOPs) are porous materials. Owing to their high surface area, tunable pore sizes and high physicochemical stability, they are studied for applications including gas capture and separation and heterogeneous catalysis. In this thesis, a series of imine/azo-linked MOPs were synthesized. LÄS MER
Sammanfattning : The current thesis presents the optimization and generalization of the Baylis-Hillman reaction applied to in situ generated imines, i.e. a three-component aza- Baylis-Hillman reaction. We found that the title reaction proceeds most efficiently in the presence of a combination of catalysts, i. LÄS MER
