Conductivity of Graphite Paper Aim The aim of this experiment is to find out how much the length of graphite paper affects the amount of electricity conducted in a circuit. I will perform a series of experiments to draw a conclusion. Method For this experiment I will be varying one factor. This factor may affect how well the graphite paper conducts electricity. The factor I have chosen is the change of length of the graphite paper. To ensure that my test is accurate I will have
Resistance of a Piece of Graphite Paper is Affected by the Width of the Graphite Paper Planning I will be investigating how the resistance of a piece of graphite paper is affected by the width of it. The aim of the investigation is to carry out a suitable experiment to find various different resistances for various different widths of graphite paper. Preliminary Experiment The purpose of the preliminary experiment is to find a suitable length of graphite paper to use in the real experiment
Tennis rackets today are made from a high modulus graphite and/or carbon fibre, which is used to keep the frame lightweight and stiff for increased racket head stability and performance. The process of them being made quite a few steps. Step 1, there are two ways you can form the frame of an aluminum racket

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
particular artist is communicating. Drawing or making marks has been around longer than any other art form as cavemen where the first to discover the art. Since this time artist have been able to manipulate line and colour using not only pencil or graphite, but using charcoal, ink, water colour pencils and micro pens, creating a mixed media artwork classified as contemporary drawing art. The artists Keith Barley, Caitlin Hackett and Kiel Johnson all have very unique styles of drawing and the language
In 2010 two Russian-born scientists pioneered and synthesized a form of “wonder material” that generates heat and electricity at faster speeds, copes with high temperatures, and is almost transparent. Graphene is arranged in a flat hexagon lattice (like microscopic chicken wire) and is one atom thick two-dimensional 〖sp〗^2 bonded carbon. It is the world’s thinnest and strongest material, which can be manufactured into a plethora of provisions that can be used for next generation technology, such
produced what he calls “Arch.” The machine was a vacuum like cylinder that would create a small wind storm inside the cylinder when activated. Sommerhasuer would tape paper on the inside of the cylinder and would toss in pencils after. He watched as the pencils would rotate around, leaving bits of graphite marks on his sheet of paper. Many trials later, “Arch” was created. “Arch,” can be described as a steep hill losing altitude as you look to your right, after
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
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 of 30 in graphene membranes
1 Part A – Nanoscale Technology This section of the report will contain a detailed description of composite materials and nanoscale technology. An investigation will then be carried out on the use of nanoscale technology in composite materials, focusing on the approaches used for incorporating graphene into composite materials and what effect it has on the final product. 1.1 What are Composite Materials Composite materials are simply materials created by combining two or more materials with different
Polyolefin: It is one of largest group of organic thermoplastic polymers [1] as well as because it’s non-porous or non-polar and odorless material that is used in structural plastics, consumer goods, food packaging and industrial products. Polyolefin states “oil like” and is commonly cited to as thermoplastic or polyalkene has a waxy texture. This type of compound for the most part utilized in the field of research and production in the petrochemical and organic chemistry industries. The production

work involves cutting a heart out of paper (fold the paper, then follow the pre-drawn dotted lines to cut the heart shape), the children in this class are familiar with cutting works as there are always about three available. It is important to note, that the children were asked to cut out their hearts and put them in a plastic ziploc bag when they were finished with them, the ziploc is a new thing for all the kids. I watch as A. cuts the heart out of the paper. He starts to look around the classroom
Carbon-fiber-reinforced-polymer (CFRP) is a composite polymer made up of carbon fibers and a binding polymer. The binding polymer can be a thermoset resin or thermoplastic polymer(s). Examples of thermoplastic polymers that can bind with carbon fiber to make CFRP are polyester, nylon, or vinyl ester. A thermoset resin that can combine with the carbon fiber to make CFRP is epoxy. The combination of the carbon fibers and a thermoset resin or thermoplastic polymer producing CFRP results in a light
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 on the allotropic form, the physical properties of carbon vary, for example, the diamond is transparent and graphite is black and opaque. I also chose carbon because it has untapped potential to benefit our lives and its many uses continue to
Self-Analysis Before taking this course my writing styles and habits were very different. I was the typical procrastinator because I would wait until the night before a paper was due to start it. This did not allow me enough time to properly proofread everything, which resulted in getting points deducted for simple grammatical errors that could have been avoided if I would have had the time to proofread. My writing styles have many strengths and weaknesses and I have been able to improve my
It is important to have good grammar, punctuation, and spelling, but what you have to say is the most important. People spend so much time worrying about what their paper looks like, then what it sounds like. Sitting down to write a paper can be intimating and sometimes it is hard to organize our thoughts to put them down on paper. I feel that reading books like Style: Lessons in Clarity and Grace is helpful, but practice is the key to good writing. I had never heard of Blooger.com until I was
