Carbon is ubiquitous: we wear it, write with it, and 18.5% of our body is composed of it. By mass, carbon is the fourth most abundant element in the universe. Carbon is the element marked with the symbol C and the atomic number six. Carbon is nonmetallic; although, it is sometimes considered a metalloid. Carbon is composed of six electrons and four valence electrons. I chose carbon because of its many useful allotropes of which the three most well known are diamond, graphite, and graphene. Depending

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. Through researching both organic and inorganic materials, I have come to understand that there are many
Simple metal hydrides contain hydrogen in their crystal structure. These simple metal hydrides include binary and intermetallic hydrides. Binary hydrides contain only one metal and generally represented as MHx, were M stands for metal. The intermetallic hydrides contain at least two metals in addition to the hydrogen and generally represented by the formula AmBnHx, where A, B are metals. These are further classified in to AB (CsCl structure), AB2 (Laves phase), A2B (AlB2 structure type)
Introduction Carbon exists in different forms such as graphite, amorphous carbon, and diamond, among others. Its graphitic carbon has a hexagonal and crystalline structure that easily cleaves which in turn makes it a soft material and effective lubricant. Its widely occurrence in earth’s crust makes it one the most abundant elements. Carbon presents itself in different allotropes such as Graphene, fullerenes and carbon nanotubes. Some of these allotropes have proven to be conducting and others to
Drilling is a very significant and common activity which is used in many fields and industries in our everyday life; such as oil drilling and construction. Drilling requires large mechanical devices that dig deep into the ground and sometimes through several layers of rock and mineral. Drilling machines have a rotating mechanical tool attached to them known as drill bits which are used to cut and remove materials in order to penetrate deep below the ground. Drill bits come in different shapes, materials
I. Abstract This paper will provide a detailed discussion about iron metal. The chemical, physical and mechanical properties of iron metal will be discussed. Additionally, the occurrence and major applications of the metal will also be provided. This is intended to provide an understanding of the iron metal and the chemistry around it. The geometry of coordination together with the different oxidation states will be included in the discussion. It should be noted that iron is one of the few metals
Well, Expo 2020 is basically the world exhibition which will be held in Dubai, UAE in 2020. Expo 2020 is a global exhibition where countries will showcase their pavilions. The theme of Expo 2020 is Connecting-minds, creating-future which actually has three sub-levels which are Sustainability, Mobility, and Opportunity. Furthermore, Sustainability is the progress and the prosperity without the compact and the needs of future generations. Mobility is unlocking new possibilities for the people and Opportunity

Expo 2020 in Dubai, is set to be a very impactful event that will bring minds together to find solutions to global issues. The miraculous multi-functional material graphene will surely be featured in this world fair and it will definitely play a huge role in the future of not only the UAE, but also the entire world. Dubai is assigned to host the prestigious World Expo in 2020, a huge global event that acts as a stage to showcase new innovations and inventions that are mainly concerned with finding
flexible and exceptionally light weight at the same time. There are two materials which could potentially fit the criteria and this report will examine their feasibility in developing a space elevator. There are two possible candidates at the moment, carbon nanotubes and diamond nanothreads which we will discuss in section 2.0. 1.2 Literature Review 1.2.1 The Eiffel Tower Inspiration – Konstantin The idea of a space elevator is not entirely new. It was first envisioned in 1895 by a Russian Scientist
Material Science in Tennis Material science is the design and discovery of new materials that emphasis on solids. It is one of the big areas of innovation in technology today and also in the sports engineering that includes tennis and also across many sports. In some classes of sailing, the materials used play an important role in the performance innovation as the boat designs cannot change. Each and every sport is unique as the equipment design and the performance differs. Tennis rackets, a key
Graphene is a single thin strongly packed layer of pure carbon atoms that are joined together in a hexagonal honeycomb matrix. In more comprehensive expression, it is a carbon allotrope arranged in a flat sp2 bonded atoms with a very small molecule bond length (0.142 nm). Graphite is formed by the arrangement of graphene layers on top of each other, with tiny inter planar gaps (0.335 nm) (Cohen-Tanugi and Grossman, 2012). This quite novel material has progressed rapidly toward scaling up production
chemical process that occurred involved the reaction of sodium phosphate and organic compounds found in urine at the high heat at which brand was boiling the urine. This reaction produced carbon monoxide and elemental phosphorus which then condensed and solidified in the form of the white phosphorous allotrope, which has a tetrahedral structure, is insoluble in water, and is highly thermodynamically unstable. He named the element, though he was not aware it was an element at the time, phosphorous
Lab: Triple Point of Dry Ice Introduction When a substance undergoes a triple point change, then it goes through all three of the states of matter: solid, liquid, as well as gas. When all three matters exist at the same time, it is extremely rare and an interesting sight to experience. A triple point is defined, specifically, as “ the temperature and pressure at which the solid, liquid, and vapor phases of a pure substance can coexist in equilibrium” (1). An excellent example of a substance
environmental change” Greenhouse Effect: Apart from water vapour there are six main greenhouse gases in our environment carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride. The first three occur naturally in the atmosphere will the others are synthetic and used in industry or as the by-products of industrial processes Carbon Dioxide: Carbon dioxide is produced through respiration of all aerobic organisms, emitted from volcanoes and other places where the
