We would like to express our sincere gratitude and appreciation to Mr Tan Hoe Teck and Ms Kassandra Lim, without whom this project would not have been possible. We are grateful for their undying support and invaluable guidance throughout the course of this project. As dedicated teacher mentors, they gave us prompt and comprehensive replies whenever we had queries, aiding us in every way possible.
We would also like to extend our thanks to the helpful laboratory staff, who stayed back in school to provide students with all the needed materials.
Last but not least, we would like to thank the School of Science and Technology, Singapore for giving us the opportunity to conduct this research.
