Allotropes of carbon

The Purification of a Gem (Topic 2) A rough, dull gemstone is put inside a scorching, blazing furnace, which breaks down its flesh, melting and refining its impurities. Through this excruciating process, a strong and beautiful gem is born to serve a variety of meaningful purposes--from becoming a gift for someone we cherish to being used as a healing stone. There is no better expression for the turbulent time of childhood and adolescence that have made me who I am today. The past twenty years were a time of great struggle and perseverance, which have made me stronger and more humble. The process was agonizing, but in the seemingly endless dark tunnel, I believed that my family was growing and that God would put together all the trials and hardships into something good. The origin of the problem was my family. My mother developed severe depression from her painful relationship with my father, both struggling with their own unsettled scars of childhood. Countless events drove my family to the edge of a precipice. My mother attempted suicide multiple times, and I vividly remember the ambulance sirens, police cars, and intensive care unit in the emergency room. My house was so unstable that it was like a ship violently rocking back and forth in the middle of a dark ocean, on the brink of being shipwrecked, broken, and lost... On these devastating days, all I could do was pray with my rosary in one hand and a handkerchief in the other for my broken heart. It is a miracle that…

space travel. One might ask what is involved with space travel? A lot of times fuel for the rockets come to mind, but there is also the making of the rocket itself and how they breathe all the way up into space. A method they use for breathing in space is electrolysis. Other factors are the diet, the removal of waste, and the impact of space. In spacecraft fuel the two main categories are liquid and solid rockets, which have different combinations and impulse values. In the development of a…

the common elements is Carbon (C). Carbon is essential for life and other important areas of the world. Carbon is a non-metal, that is in a solid state at room temperature. There are many different unique properties that help Carbon do what it needs to do. Carbon is the sixth most abundant element on Earth, and used in the daily lives as oil or coal. The origin of the name is Latin, coming from the word Carbo. Carbon was date discovered is not known specifically but has been known since ancient…

Introduction Graphene is considered as pure carbon in the form of a very thin, one atom thick nearly transparent sheet. It is very strong for its low weight (100 times more stronger than steel and it conducts heat and electricity efficiently. While scientists had theorized about graphene for decades, it was first produced in the lab in 2003. Because it is virtually two-dimensional, it interacts oddly with light and with other materials. Researchers have identified the, ballistic transport of…

CHAPTER – 1 1. INTRODUCTION Carbon nanotubes are allotropes of carbon with cylindrical nanostructure. Constructed with length-to - diameter ratio of up to 132,000,000 :1. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. Nanotubes are members of fullerene structural family. Nanotube’s walls are formed by one-atom thick sheet of carbon called Graphene. The combination of…

begin, Kean introduces the periodic table to readers, in a creative and approachable manner. He metaphorically compares the table to a castle, with each brick representing a different element. This analogy gave me a different perspective about the table, and a deeper appreciation for its thoughtful layout. His second metaphor, the periodic table as a map (or castle blueprint), allows the reader to quickly recognize characteristics of elements based on their location, that is, their…

Philippines Department of Food and Nutrition, College of Home Economics, University of the Philippines, Diliman, Quezon City 1101 Philippines Abstract ------------------------------------------------- ------------------------------------------------- The purpose of this experiment is to observe the synthesis of esters (also known as esterification), to understand the chemical processes that ester synthesis undergoes, and to know the optimum conditions needed for high yields.…

emissions are among the highest per capita in the world" (Marsa, 123). Australia releases more emissions than any other country because Australia has an over abundance of coal, as well as agricultural resources such as sheep and cattle. As a result, people tend to use the resources that are readily available without knowing that it is causing irreparable damage to the environment. In the article Marsa makes reference to James Cook, who states: " 'We have an economy that is deeply reliant on…

designated carbon site was unstable and yielded a formal charge of 1+, an indication that it had too many bonds than required. The bisulfate ion formed earlier removed a proton to form a more stable hydroxyl group. However, the site of formation or placement of the hydrogen atom and the hydroxyl group is governed by Markovnikov’s rule. Markovnikov’s rule sheds light on the regioselectivity of the two ends of a C=C double bond of an alkene when they are not identical. It is used to predict the…

Beryllium General Characteristics According to Hornbostel (1991), Beryllium is a hard, exceptionally, lightweight, gray-white metal, corrosion resistant at ordinary temperatures; chemically it is related to aluminum. Other than titanium, it is the only light metal which has both good strength and a high melting point. Additionally, it is a good electrical conductor, has high modulus of elasticity, exceptionally transmit x-rays and sounds at very high velocities. Moreover, it has the ability to…
