Personal Statement Yun Yu Lai Macromolecule Science & Engineering Thanks to my family background, I have been immersed in the atmosphere of novel technology, particularly in the field of material science. My mother has worked as a project manager at the Industrial Technology Research Institute (ITRI), Material & Chemical Laboratories (MCL), which is served as the heart of high-tech research center in Taiwan. I always remember our family dinner time that she shares with us the latest prototype from MCL (E.g. liquid-crystal display, polarizer, and organic light emitter diode). It is an unforgettable memory that you could recognize the LCD monitor in the era of cathode ray tube (CRT) television. Although I am was too young to realize the principle of these technologies, the curiosity of exploring the material’s world becomes a seed in my mind. …show more content…
For instance, we incorporate various metal ion compounds and further flame with different colors. (E.g. Potassium ion: purple, Copper ion: blue green) At first glance, it is hard to imagine that we could operate firework effect in domino competition, but we successfully light up our school’s abbreviation “NEHS” into the air. The scene looks like the sparkling stars in the silent sky along with the vigorous flaming sound. This great experience not only gives me the medal but ignites my scientific interest, thereby makes me determine decide Applied Chemistry as a college major at National Chiao Tung University

Miodownik describes in detail how natural elements were manipulated by man to create man-made materials at the same minuscule scale that take place naturally. Materials science has provided the knowledge required for
The first thing in a firework is the oxidizing agent. These produce the Oxygen to burn the mixture. Oxidizers are usually nitrates, chlorates or perchlorates. The common oxidizers are nitrates. These are made up of a metal ion and the nitrate ion. I'll use potassium nitrate as an example. Nitrates only give up 1/3 of their oxygen. The resulting equation would look something like this:
This smoke bomb lab helped me understand chemical bonding and reactions by starting from the very beginning with mixing the nitrate, sugar, and melted crayon. Mixing them formed a texture almost like powdery peanut butter with some liquid which was actually pretty interesting. The second chemical bonding I seen was that, once putting the solution in the tin-can and it started solidifying due to all the stuff we mixed together. It didn’t take long at all for it to start forming into a solid. When we went outside and lit the wick on fire showed the main chemical reaction throughout the whole experiment. The nitrate reacting with the lighted wick started a big fire in one of the groups cans but some of the other groups bombs didn’t get to light like it was supposed to and the wick just burned out. I was one of the groups whose bombs didn’t work properly. I think it’s because we didn’t put the wick in deep enough to our solution so when we lit it the fire just burned out before going into the solution.
Colored fire is a common pyrotechnic effect used in movies, fireworks and by fire performers all over the world. Generally the color of the flame may be red, orange, yellow, or white, and is controlled by blackbody radiation from soot and steam. When additional chemicals are added to the fire, the flame would appear a different color according to the other chemicals. Flame coloring is also a good way to show how chemicals change when heated and how they change the matter around them.

The investigation topic is about the fuel that makes a space rocket fire. A combustion reaction is more known as burning. Combustion isn’t always burning, but when it is, the flame causes most of the reaction ( in our case, to make our bottle fire up ). We light the fire with a match, the heat from the flame may provide the sufficient energy to to make the reaction happen.
Users can create, shape and manipulate fire, the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products, flame being the visible portion of the fire. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different.

Chemistry is in our everyday lives. When we wake up in the morning to when we see fireworks on 4th of july. People everywhere enjoy the fantastic explosions and the beautiful, bright, light displays of fireworks. Although, these spectacles are much more than just a form of entertainment. There is real chemistry packed into every firework.
Firework Science Report Ruby Zhang Serendipity can be defined as unplanned happening, “pleasant surprise” (Walpole, 1754) that happened when it is well prepared. However, it happens often in scientific field when doing experiments, and firework is one of them. Fireworks were discovered 2000 years ago when a Chinese cook serendipitously mixed three common kitchen ingredients together. Salt substitute (potassium nitrate), sulfur, and charcoal were heated up by fire creating a colorful flame when burning. The cook did not intend to mix the three kitchen ingredients to produce this product.
‘Research is creating new knowledge’, as said, since my childhood I was always into experimenting on things, even the smallest radio set in my home was a huge miracle to me as a child. Exploring into the parts of it was great learning. So thus my interest towards technology has begun, which made me participate and win various Science fairs conducted during school level. I stood FIRST in the SIR C.V.RAMAN test as an outstanding student in Science. Being one of the best students in my school I have scored 77% , which was one of the listed topper’s grades, in my X Standard.
Proteins are considered to be the most versatile macromolecules in a living system. This is because they serve crucial functions in all biological processes. Proteins are linear polymers, and they are made up of monomer units that are called amino acids. The sequence of the amino acids linked together is referred to as the primary structure. A protein will spontaneously fold up into a 3D shape caused by the hydrogen bonding of amino acids near each other. This 3D structure is determined by the sequence of the amino acids. The 3D structure is referred to as the secondary structure. There is also a tertiary structure, which is formed by the long-range interactions of the amino acids. Protein function is directly dependent on this 3D structure.
I then joined my first mentor Prof Winston T-K Cheng ’s lab (he is renowned as the world's first scientist to produce test-tube
The growing relevance of Chemical Engineering in today’s world, from energy & oil industries to pharmaceuticals & biotechnology, and a keen desire for applying this knowledge in interrelated spheres motivates me to pursue a Master’s degree in this field. My interest in science goes back to the time when I was in school. We had a young and enthusiastic teacher who took us on field trips and visits to science fairs and museums. This nascent interest has only burgeoned through my years in school and high school, as I have learnt more about the subject. In the long run, I see myself as a part of a leading research group, either as a faculty member or in the R&D department of an organisation contributing my bit to the field of Chemical Engineering. As a research scientist, I hope to make a difference in this field and learn more through the innovative challenges.
