My beloved kids, whom i can't force myself to stop loving and my wonderful son Raed for been there to replace me and for inspire him to complet his study. To my long-time friends; Abderrahmane Mezrag, Redoun, Mohamed Zabat, Omar, Ahmed, Farid, Amar, Seif, Abbey Andreas, Siham, Majdah, Fayroz, Hanan, Loisa for their support, friendship and encouragement. I dedicate my thesis to all researchers who have concern. Acknowledgements I would like to thank all the people who assisted me with their expertise, work or emotional support in the completion of this thesis. First, I would like to thank my supervisor, Professor Amar Zellagui for giving me the opportunity to undertake this study and for all his encouragement and assistance throughout the study period. I wish to express my appreciation to my “second” supervisor, Professor. Salah Rhouati, for his support throughout the course of this research. I have special thanks to jury members, Professor Salah Akkal, Professor Gherraf Noureddine and Professor Seddik Khennouf for accept to discuss and correct my thesis. I had a special word of thanks goes to Professor Ibrahim Demirtaş from Laboratory of Plant Research, Department of Chemistry, Faculty of Science, Uluyazi Campus, Karatekin University, Cankiri, Turkey and Dr. Susana M Cardoso, from Department of Chemistry & QOPNA, University of Aveiro, Portugal for excellent technical information and discussion, for being a real mentor to me and for finding the answers to every “difficult question”, they were a great source of optimism and passion of this part of chemistry. I would like also to acknowledge other postgraduate students and staff members in Chemistry Department, I would also like to thank my lab-team and my lab neighbors.
