We would like to express our deepest appreciation to School of Science and Technology, Singapore for giving us this unique opportunity to learn about and conduct research in our area of interest in Science. The program was very well thought out by the teachers and catered to provide us with information we did not know previously.We would like to express our gratitude for our mentor, Mr Tan Hoe Teck, for the suggestion of this research topic, the patient guidance, and critiques of the research project and experimental process. We would also like to thank our teacher, Mr Teng, for his guidance in writing the research proposal and the research paper. Our grateful thanks are also extended to the lab techs who helped us out at every turn and provided constructive feedback when something went wrong. Finally, we would like to thank the various SST students who helped us while we were away to watch the experiment and caution us when something was amiss.
