ACKNOWLEGEMENT
Firstly i would like to express by gratefulness and thanks to ProfessorHenri DELMAS, who gave me the opportunity to join his group under the project of CEFIPRA, and directed me with his valuable guidance through my thesis work. I take this opportunity to express my gratitude and obeisance to Mdm.Carine JULCOUR-LEBIGUE, her naturally gifted power to understand and ability to simplify the most perplexing problems has made a permanent mark in me. Without her support and open mind for new concepts, without the freedom to explore new ideas, and eventually without the patience she had with me, this work would not have been as fruitful as it was.
I would like to acknowledge Prof. R.V. Chaudhari and Prof. Claude de Bellefon for accepting to be the Rapporteur of my thesis and. Prof. Michel Prevost and Dr. François Malbosc to be a part of the jury member. I’m grateful for their valuable suggestions on the thesis work. During my PhD research project, I have also worked for a short span at the “National Chemical Laboratory”, Pune, India. I owe my special thanks to Dr. R.M. Deshpande and Dr. A.A. kelkar for giving me the opportunity to work in their group at the High Pressure Lab., NCL. It was a pleasure working in NCL under their supportive guidance and very friendly research group. I also would like to express my gratitude towards all the faculty and staff members of LGC for their invaluable help. Special thanks to Jean-Louis LABAT, Ignace COGHE, Lahcen FARHI, Jean-Louis NADALIN, Alec MAUNOURY and Lucien POLLINI for their great expertise in the Autoclave reactor set-up and troubleshooting and also for their friendship. I wish to thank Christine REY ROUCH for her great help in conducting experiments with TGA, Martine AURIOL for helping me with Gas-chromatography, Marie Line DE SOLAN and Serge MOUYSSET for conducting SEM and ICP analysis
and Marie-Line PERN for helping me with the viscosity experiments. I also owe my gratitude to Marie MORERE for her help in the operation of Head space Gas Chromatography. Also thanks to Luce Bernard for her help and cooperation during the HSGC experiments. I also express my special thanks to my colleagues Frederic, Carmen, Cathy, Isa, Rana, Harold, Joaquim, Elham, Marianne, Gaelle, Hicham, Abdullai for their kindness and a very nice time during my whole PhD tenure. I want to acknowledge your geneorisity for having such a wonderful time in Europe. I always look forward to spending time with you. I cannot complete this acknowledgement without mention of my beloved family members Mumma, papa, Bhaiya and Richa who have put in their efforts and prayers for me to attain success in life. I am falling short of words to express my feelings towards them. Their blessings and encouragement were beyond comparison. Words are forgotten…..
Memories are remembered……..
