Graphene And Its Effects On Our Environment

Such as stated earlier in the paper nanotechnology in the near future can “help decrease production costs by reducing energy consumption” (Sabry and Nesreen. 119). The investments put toward nanotechnology to create an energy efficiencies tool that would make the cost of productions like food and clothes decrease. By decreasing things that are basic needs, it open opportunities for things that was not affordable before for example like the iphone or any other expensive tech. Since consumers now have enough money to buy the newest iphone their sell profits will go up. With the increase in profits Apple Inc. has the money to invest in a new development with

In 1779, Carl Wilhelm Scheele showed another allotrope of carbon graphite, which were known as a form of lead in early times. He found out that graphite was almost identical to charcoal except a small admixture of iron, and when it oxidized with nitric acid, it gave out “aerial acid” (carbon dioxide). In 1786, the French scientists Claude Louis Berthollet, Gaspard Monge and Vandermonde confirmed that graphite was mostly carbon by oxidizing with oxygen in the same way

The use of nano-materials and extreme precision micro-engineering has the potential for great improvement in the world of electronics and information technology by providing smaller, faster, and more powerful computers and this has been at the forefront of the nanotechnology commercialization . Great examples of how nanotechnology is currently being used in these fields are products such as processors, data storage, and memory components made with nano-materials, TVs, monitors and even smartphone screens that use organic light-emitting diodes (OLED), and waterproof electronics such as smartphones due to the application of nano-coatings

Some examples of compounds formed by carbon include diamonds which are pure carbon and are the hardest substance known to man with no known other material that can cut them. Graphite which is also a pure carbon-based molecule can be found in your pencil as lead. The oil in our cars is made of carbon, and the plastic of your keypad is carbon-based. Additionally, Carbon nanotubes which can self assemble and provide not only incredible strength, but also electrical, optical, thermal and kinetic properties like no other materials (The Biochemical Essense of Life: Carbon, n.d.). Another key feature of carbon is that its bonds are strong enough to resist environmental stresses, but weak enough to be manipulated by our bodies with enzymes which is a requirement of any organism’s metabolism (The Biochemical Essense of Life: Carbon, n.d.).

Different structural arrangements in the carbon atoms determine the outcome of the mineral. Diamonds are the hardest mineral; they are formed under a covalent bond which is very strong. Graphite on the other hand is one of the softest; it is held with a softer bond. Despite the difference in structure, both of these minerals are made from the same substance, pure carbon.

Graphene is easy to make you only need Scotch tape and some pencil lead (carbon is not lead it is graphite). It is one of the most versatile elements and is in all forms of steel. Due to graphite being so soft it is a great lubricant and can be bought in a very fine powder for that application. Diamonds are one of the hardest material. Diamonds have found applications in jewelry to tools and equipment. The best tools you can buy have micro diamonds inserted into the metal of the tools. Diamond drill bits are able to drill into hardened metal without breaking or severely disfiguring the bits. However if you heat diamonds up to much they will be oxidized into carbon dioxide. Fires make micro diamonds that almost immediately burn up. The structural difference of these two forms are interesting. The graphite has a hexagonal structure, and the diamond has a square crystalline structure which accounts for its hardness. Since carbon is a group 4a element, meaning it has two inner electrons and four outer and needs four or to give four electrons to get its perfect form, and most bonds of carbon are hexagonal or like a tree with branches coming off from the carbon. Carbon has the highest number of possible bonds of all of the elements, which is why it is the basis of life and organisms are able to be so different.

The purpose of immobilising enzymes before they are used to catalyse a reaction is to be reused again because they are not completely lost in the solution. We immobilised lactase enzyme by dissolving it in sodium alginate gel. This is one of the more widely used practises in industry as it is very efficient and effective. We can see that by our experiment by immobilising the enzyme and could retain it even after it has been involved in the reaction by catalysing the breakdown of lactose in glucose and galactose.

The use of the classic engineering design approach has been a deciding factor in the ability to make more rapid progress. Understanding the physics, mathematical models, and parameters allowed the optimization of sensor design. Multiple disciplines have allowed sensor signaling, experimental in vitro, and product testing to be applied to the process of the engineering design. “The development has been based on principles of mathematical modeling, chemical engineering, materials engineering, electrical engineering, dynamic systems analysis, enzymology, organic chemistry, electrochemistry, physiology, tissue engineering, and manufacturing. Research groups that have taken narrow disciplinary approaches limited to only a few of these areas have been

While graphene has become one of the leading researched materials in electronics it was found that large area graphene does not have as many useful properties as graphene nanoribbons. The nanoribbons are graphene that has a finite width.

Graphene is a form of carbon which has recently been receiving a great deal of attention. Some have come to call it “the wonder material” due to its many extraordinary properties. Although isolated in 2004, graphene's properties had been calculated decades earlier. It consists of a single layer of carbon atoms arranged in a hexagonal lattice. A single sheet of graphene is stronger than steel and yet remains very flexible, retaining all of its properties despite being bent and unbent multiple times. It is able to sustain extremely high electric current densities, is impermeable to all gasses, has a thermal conductivity double that of diamond and a very high electron mobility at room temperature. It is also easily chemically functionalized,

Figure (2) shows the Raman spectrum of prepared activated carbon (AC). The sample shows the characteristic D and G carbon peaks at 1380 cm−1 and 1585 cm−1, respectively. In simple terms, for carbon materials, the D peak intensity correlates with defects in the carbon lattice and is linked to the extent of sp3 hybridization while the G peak arises from the graphitic network and extent of sp2 hybridization. ID/IG = 0 .663, it is smaller than 1, so the structures are considered to show a higher concentration of sp2 hybridization (i.e. extended graphitic character). Moreover, the ratio is close to 1 then the material is considered to have a more amorphous structure with a mixture of sp2 and sp3 hybridization. In this case, where ID/IG is close to 1, the presence of a 2D peak, further associated to interactions between graphene-like planes, suggests a strong graphitic component.

Nanoscience is a rapidly-developing field that covers a wide-range of application in a large variety of areas of science and technology. It is a phenomenon and manipulation of materials at atomic, molecular and micro molecular scales, where properties differ significantly from those at a larger scale. The subject nanotechnology deals with study of manufacturing and manipulation of matter at nano-scale in the size range of 1-100 nm in any of the one dimension of the object which are called as nanoparticles (Rajan, 2004). Nanoscience and nanotechnologies are widely seen as having huge potential to bring benefits in areas of interfacing physical, chemical, medical, biological, agricultural, environmental, and engineering sciences with myriad
