Jean-Marc Jung Professeur, Université de Strasbourg (– IPHC) Rapporteur M. Philippe Moisy Directeur de recherche, CEA Marcoule Rapporteur Mme Sophie Le Caer Directrice de recherche, CEA (– LIONS) Examinateur M. Khashayar Ghandi Professeur, University of Guelph Examinateur M. Mehran Mostafavi Professeur, Université Paris-Sud (– LCP) Directeur de thèse Acknowledgements Firstly, I would like to express my sincere gratitude to my advisor Prof. Mehran Mostafavi for the continuous support of my Ph.D study and related research, for his patience, motivation, and immense knowledge. His guidance helped me in all the time of research and writing of this thesis. I could not have imagined having a better advisor and mentor for my Ph.D study. Besides my advisor, I would like to thank the rest of my thesis committee: Prof. Jean-Marc Jung, Dr. Philippe Moisy, Dr. Sophie Le Caer, Prof. Isabelle Lampre and Prof. Khashayar Ghandi, for their insightful comments and encouragement, but also for the hard question which incented me to widen my research from various perspectives. I would like to thank Dr. Pascal Pernot, Dr. Pierre Archirel and Dr. Aurélien De Lande for their strong support, collaboration and insightful encouragement for my Ph.D research. Their excellent computation makes important sense to my thesis. My sincere thanks also goes to Prof. Jacqueline Belloni, Dr. Jean-Louis Marignier and Hydn Remita. Their personalities, curiosity to the science, the ways of thinking and performing research encouraged me to be a person Iike them. I would like to thank the engineers in our team, Dr. Uli Schmidhammer, Dr. Sergey Denisov, Jean- Philippe Larbre, Audrey Gayral, Pierre Jeunesse, Alexandre Demarque and Nicolas Decovemacher. Without them, I can’t perform experiments in ELYSE. I take this opportunity to express gratitude to all of administration group in the lab for helping me focusing the research, they are Séverine Bourguignon, Eve Ranvier, Anne Morel and Delphine Lelievre. I thank Mireille Benoit for careful arrangement of all the chemical compounds during my Ph.D. My sincere thanks also goes to my dear friends, Anna Balcerzyk, Jun Ma, Abdel Karim El Omar, Zhenpeng Cui, Xiaojing Wu, Xiaojiao Yuan, Viacheslav Shcherbakov, Raluca Musat, Teseer Bahry, Sarah Al-gharib…… I couldn’t put all their name on the list. We have good time through my four year’s life. I really enjoy the life here and never forget the memory in LCP. Last but not the least, I would like to thank my family: my parents and my sister. My study is always baked by their support.
