In conclusion, everyone has the chance for themselves to make their own definition what it means to be an American. Having the American Dream, otherwise being successful, you can choose how you view being American. As I have previously explained in this essay, I believe being American means that you are a proud patriot of your country and show some type of position in your country, having a voice in your country and using your liberties promised to you by the government. What is your definition of being an
Solid Freeform Fabrication(SFF) has been possibly the most large scale fabrication technique among the different types of design and fabrication methods (Bose, et al., 2012). The main feature of SFF has three dimensional parts which are printed layer-by-layer depending on computer aided design (ask plagiarism). The fabrication of SFF on polymer, ceramic, metal and composite scaffolds has been widely accepted in bone tissue engineering applications (Bose, et al.,

They can be seen as a collection of rolled sheets of graphene. CNTs demonstrate superconductivity with very large temperature transition. Electrons transport and resistance of CNTs do not depend on the sizes of CNTs. Carbon nanotubes electrodes are constructed by combining graphite powder and multiwall carbon nanotubes in a pestle and a mortar. Then, paraffin is added to the mixture by a syringe before the mixture is packed in a glass tube. After the construction, its electrochemistry is tested to verify its electro-activity by using standard solution of Fe(CN)63-/Fe(CN)64. Care is taken on information about electrode interfaces; mass transiport needs to be minimized in order to be used in catalysis, sensing and electrodeposition (Elrouby, 2013).
An American is someone who is free to do whatever whenever he wants. He is someone who doesn't care about who judges him or what people think. All he cares about is his version of the American dream. His version may be different from everyone else's but an American has the freedom to be different in whatever way he wants to. This is what an American is.
What does it mean to be a citizen of the U.S.A, well it means much more than just that fact that you are a citizen, but it in itself is an exceptional obligation to me. To be an American means many things to me. To be an American means that you are a part of one of the greatest countries in the whole world. To be an American means that you have freedom, to do almost anything as much what you want and to say what you want as long as it is constitutional. It means that you have equality because everyone is given an equal chance here. It means that you have the right to go out and chase your dreams and strive for your goals. To be an American also means that you are a citizen in one of the most diverse countries in the world and that you must
The advancement of material science over the past decade has allowed the scientists to create two structures of carbon namely carbon nanotubes and carbon nanowires. Nanowires are small wires with a diameter as small as 1 nanometre. These are being used to build tiny transistors with higher efficiency for computer chips and other electronic devices. In the last couple of years the carbon nanotubes have somewhat overshadowed the nanowires. A carbon nanotube is a cylinder full of carbon atoms. To put it into simpler words, nanotubes are simply sheet of carbon atoms in hexagonal shape. If this sheet is rolled into a form of a cylinder, you have a carbon nanotube. The properties of this carbon nanotube are based on how the sheet is rolled. Although they are formed from the same graphite sheet, their properties are dependent on the variations in length, thickness, type of helical structure and number of layers.

America isn't the chocolate lab pacing the white picket fence of a suburban bungalow, but rather every principle set in place to make that dream a reality. Being an American means having the freedom to live your life without intrusion; the freedom to liberty. It means having the freedom to make something of yourself, the pursuit of happiness. And finally, being an American means that your race, sex, nor orientation matters, you will not be denied your rights. America was founded on the principles that all people should have the freedom of life, liberty, and the pursuit of happiness.

...s in these structures are covalently bonded. Many types of fullerenes are arranged in large groups (many dozens of carbon atoms). Types of fullerenes discovered include C60 and C70. They can be used in products such as carbon nanotubes which in turn are used for electronic wires, science materials, and computer memory.
In this section I will discuss racial standards of beauty and how they are constructed and represented in the media. I will talk about the toys I played with as a child and what type of television I watched as an adolescent. For this paper, I will draw on the social concept definition of race. The social concept definition of race rejects the biological traits that are associated with race and is based on "specific social relations and historical contexts" that are associated with racial categories (Omi and Winant, 12-13).
Fullerenes are accepted as the fourth for of solid carbon after amorphous, graphite and diamond forms. Fullerene chemistry has provided a new dimension of aromatic and a new platform for discussion of mathematical techniques pertinent to large cages. They are basically, large carbon cage molecules. These fullerenes have attracted great interest a large number of physical and chemical properties. These properties of nanostructures strongly depend on this size, shape and chemical compositions. This property leads to very interesting and recent applications in medicinal chemistry, material science and nanotechnology. Functionalization, intercalation and doping by the addition of electron acceptors or donors are the way of modifying the properties of these nanostructures. Among these nanostructures carbon based nanomaterials such as nanotubes, nanocages, nanoshells,
In 1759 Hallwell repaired the injurd artery using wooden peg and twisted thread it was first time when biomaterials were used (7). Later on Lister developed aseptic methods for surgery in 1980 (8). Bone plates were used to repair the fractures in 1900 as a use of biomaterials (3). With the advancement of time newer more convenient materials were introduced. Later stainless steel and cobalt alloys were used in fracture fixation in 1930(3).
