1. Graphene-based nanocomposites for electronics and photocatalysis
Abstract : The development of future electronics depends on the availability of suitable functional materials. Printed electronics, for example, relies on access to highly conductive, inexpensive and printable materials, while strong light absorption and low carrier recombination rates are demanded in photocatalysis industry.

2. Some New Methods in Sialic Acid Chemistry
Abstract : Gangliosides (G) are sialic acid-containing cell surface glycosphingolipids capable of forming lactones, i.e. inner esters. Some gangliosides are tumor-associated antigens, and they may serve as immunogens in their lactone form, where the latter is comparatively more abundant on the surface of malignant cells. READ MORE

3. Transition Metal Mediated Transformations of Carboranes
Abstract : This thesis describes the use of copper and palladium to mediate transformations of carboranes, especially p-carborane.1-(1-p-carboranyl)-N-methyl-N-(2-butyl)-3-isoquinolinecarboxamide, a carborane containing analogue of the peripheral benzodiazepine receptor (PBR) ligand PK11195, has been synthesised.

4. Supercritical Hydrogenation of Vegetable Oils
Abstract : Vegetable oils were hydrogenated in a supercritical single-phase mixture with propane and hydrogen. The reaction was carried out in a small (0.5 ml) fixed-bed reactor and the influence of different process parameters was investigated. READ MORE

5. Development of Catalytic ElectrophilicTrifluoromethylation and Fluorination Methods
Abstract : This thesis is focused on development of new catalytic, electrophilic fluorination and trifluoromethylation methods of alkenes. These reactions were carried out using hypervalent trifluoromethyl and fluoroiodine reagents.The first project involved copper catalyzed oxytrifluoromethylation of terminal alkenes and alkynes.
