Reinhard Conradt who has been my supervisor both for master degree in Chulalongkorn university, Thailand and for doctoral degree in RWTH, Aachen, Deutschland. I had a very hard time in the first year staying here, nearly to give up. The kind understanding for a foreigner’s problem of him and his wife Frau Marianne Conradt helped me getting through. Working under his coaching is my honor; I appreciate for what he taught how to handle any problems in a systematic research way with his patience and encouragement in spite of many other commitments. His scientific advice not only made this work accomplished but also enlarged my vision in glass research field which is accordingly beneficial to my future carrier.
