...Super Material We are on the brink of a new era in material science and technological development, much like the world was in 1862 with the advent of polymers. No one can truly know what the lasting effect of a new product will have on the world, but graphene has the potential to propel us further into the 21st century with astounding technological might. Much like the introduction of plastic and rubber, graphene will play a role in how we live our lives. Shaping the way we work, eat, live, and play. However, in order to understand how this wonder material will change lives, we must understand what it is, define its potential uses, and overcome the significant hurdles in cheap and efficient production. Graphene can best be described as a one atom thick layer of graphite. It was first discovered in 2004 by Andre Geim and Konstantin Novoselov at the University of Manchester. It is a 2-D crystalline allotrope of carbon, the world’s first 2-D material in fact. An allotrope is just a different arrangement of carbon, like diamond for example. Due to its sp2-hexagonal arrangement, graphene exhibits special properties. Most forms of carbon exist in a sp3 arrangement, (like graphite in the image above). What this means is that graphene can exist in a 2D state. Due to this configuration electrons are free to move across the whole compound with relative ease. Endowing it with remarkably high electron mobility. This ability allows any current to easily make its way through the molecule;...

...One of the most amazing discoveries of the twenty-first century was the isolation of graphene. Graphene is a thin layer of pure carbon; it is a single, tightly packed layer of carbon atoms that are bonded together in a hexagonal honeycomb lattice.1 If we stack these thin layers upon each other it forms graphite, which is found in every pencil lead. When isolated, graphene exhibits remarkable properties that can be used to help improve the performance and efficiency of current materials and substances. Graphene was first studied theoretically in the 1940s. During this time, scientists felt that it was physically impossible for a 2D material to exist, so they did not pursue any form of mechanical exfoliation. Decades later, interested sparked and researchers began trying to peel apart the layers of graphite to isolate graphene. Scientists tried various techniques, but they never got to a single layer. Eventually, they were able to isolate graphene on top of another material, but not on its own. In 2003 a physics professor and his PhD student achieved the impossible; they were the first to isolate a single layer of graphene. Andre Geim, who won the 2000 Noble Prize for levitating a live frog over a magnetic field,2 asked a new PhD student to see how thin he could make a piece of graphite. That student Kostya Novoselov, was only able to produce a sample around 1,000 layers thick, but set in motion a side project for Geim that would turn into the scientific find of the century...

...Weisenberger 1 Center for Applied Energy Research, University of Kentucky, 2540 Research Park Drive, Lexington, KY 40511-8410 USA Received 7 October 2003; accepted 29 October 2003 Abstract The state of research into carbon nanotube/polymer–matrix composites for mechanical reinforcement is critically reviewed with emphasis on recent advances in CNT composite toughness. Particular interest is also given to interfacial bonding of carbon nano-tubes to polymer matrices as it applies to stress transfer from the matrix to the CNT. Potential topics of oncoming focus are highlighted. 2003 Elsevier Ltd. All rights reserved. 1. Introduction Since the documented discovery of carbon nanotubes (CNTs) in 1991 by Iijima [1] and the realization of their unique physical properties, including mechanical, ther-mal, and electrical, many investigators have endeavored to fabricate advanced CNT composite materials that exhibit one or more of these properties [2,*3,*4]. For example, as conductive filler in polymers, CNTs are quite effective compared to traditional carbon black micro-particles, primarily due to their large aspect ratios [5]. The electrical percolation threshold was recently re-ported at 0.0025 wt.% CNTs and conductivity at 2 S/m at 1.0 wt.% CNTs in epoxy matrices [6]. Similarly, CNTs possess one of the highest thermal conductivities known [*7], which suggests their use in composites for thermal management [2]. The main focus of this paper, however, will be on the use of CNTs...

Laptop, mobile phone, camera and otherwise are using battery to make it to function. In order to improve the efficiency the batteries, several methods are discussed in this paper. INTRODUCTION In this advanced technology era, batteries have been commonly used by the consumers. We use them in different fields like cars, mobile phone, laptop and other else. (Hiroki Kitamura, 2012).Batteries is divided into two main groups which are primary and secondary batteries. (Clean Up Australia, 2009) Primary batteries are the batteries that normally use in dairy life such as remote control, clock but for this kind of batteries is a non rechargeable battery which means that we only can use it for one time and will be throw away after used. This kind of batteries is actually converting the chemical energy to electrical energy and they are normally known as the alkaline batteries. Secondary batteries are batteries that can be rechargeable and recycle after it cannot be recharge. This batteries mostly use for our mobile phone, laptop and other. Although...

...Carbon from Latin: carbo "coal" is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. There are three naturally occurring isotopes, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity. There are several allotropes of carbon of which the best known are graphite, diamond, and amorphous carbon. The physical properties of carbon vary widely with the allotropic form. For example, diamond is highly transparent, while graphite is opaque and black. Diamond is among the hardest materials known, while graphite is soft enough to form a streak on paper (hence its name, from the Greek word "to write"). Diamond has a very low electrical conductivity, while graphite is a very good conductor. Under normal conditions, diamond has the highest thermal conductivity of all known materials. All carbon allotropes are solids under normal conditions with graphite being the most thermodynamically stable form. They are chemically resistant and require high temperature to react even with oxygen. The most common oxidation state of carbon in inorganic compounds is +4, while +2 is found in carbon monoxide and other transition metal carbonyl complexes. The largest sources of inorganic carbon are limestones, dolomites and carbon dioxide, but significant quantities occur in organic deposits of coal, peat, oil...

...You have just witness “bro science” in action. It’s wellintended. It can also be deadly. The difference between 5 grams and 5 micrograms, depending on the substance, can indeed be the difference between life and death. Where should one get such information? From qualified sources, of course. Not from your bro. Want to know about proper dosage? Look in the medical literature and find out what dosages have been shown through experimentation to render the desired effects. Want to know about a proper manufacturing method? Then you need to read technical manuals written by actual engineers. As much as possible, I’ve pointed you to more qualified sources of information than myself throughout this guide. I’ve deliberately left out information about dosages in order to force you to use this as a starting point rather than a definitive resource. At the same time, I’m obviously encouraging DIY experimentation. Allow me to clear up the apparent contradiction. See, I intend for this report to be, among other things, a bit of a shot across the bow of the troubled ship that is the nutritional supplement industry. Here’s a field that can do so much good but that exhibits so little true innovation. When anyone can privatelabel the same substandard supplements everyone else is selling and “win with better marketing,” it doesn’t seem there’s much incentive to raise the bar. The best way to shake up such a market is to educate the buyers. When consumers are aware of...

...technology. It is being used to enhance the properties of existing materials. This is largely attributed to the fact that the technology has clearly not been understood and there is still much more to nanotechnology than meets the microscopic eye. It is rare for a single technology to have the power to dramatically influence almost every major industry in the world. Nanotechnology falls into this category and offers fundamentally new capabilities to architect a broad array of novel materials, composites and structures on a molecular scale. This technology has the potential to drastically redefine the methods used for developing lighter, stronger, and high-performance structures and processes with unique and non-traditional properties. This paper focuses on some of the automotive applications for nanotechnology and showcases a few of them that are believed to have the highest probability of success in this highly competitive industry. No discussion of nanotechnology is...
