Description and Specification of Graphene - 0 views

  •  
    Graphene is a single-atom-thick sheet made from combined carbon atoms. The carbon atoms are bonded together to share electron in a hexagonal, honeycomb-like structure. It is a single atom thick layered 2D material ever discovered in the world. It is made up of a hexagonal lattice pattern of carbon atoms in a monolithic honeycomb-like structure. It is a layer of SP2 single bonded carbon atoms arranged like a chicken wire mesh. It is 200 times stronger than stainless steel (SS) and 100 thousand times thinner than the human hair. It is the slimmest and strongest compound available on the earth. Anybody would be amazed when they know that we have found a material which is harder than diamond, yet lightweight, stronger than steel, but also highly flexible, and this material can be mined from the earth as it occurs naturally. It is yet thin enough to be mistaken for a saran wrap. Apart from the optimum physical properties, the other features are also impressive. Properties of Graphene These are some prominent features which make it a hi-tech material: Excellent Electronic Conductor Chief electronic property makes it an efficient Zero-Overlap Semi metal and gives it sufficient electrical conductivity. Carbon atoms possess typically 2 electrons in the inner shell, and 4 electrons in the outer orbit, total 6 electrons. Although conventionally, the outer 4 electrons in carbon can connect with another atom, each, the atoms can form a 2-dimensional bond with three atoms per single atom. This leaves an electron available for electronic conduction. Such electrons are known as 'Pi' electrons and found above and below in sheet. Ultimate Tensile Strength Mechanical strength is another prominent property of the material. It considered as being the foremost most robust material ever discovered, owing to the 0.142 Nm-long carbon bonds. It also possesses ultimate tensile strength, measuring 130 Gigapascals (or 130,000,000,000 Pascals). Compared to the tensile strength of industr

Light Emitting Devices with Fluorographene - 0 views

  •  
    Professor Andre Geim, who along with his colleague Professor Kostya Novoselov won the 2010 Nobel Prize for graphene - the world's thinnest material, has now modified it to make fluorographene - a one-molecule-thick material chemically similar to Teflon. Fluorographene is fully-fluorinated graphene and is basically a two-dimensional version of Teflon, showing similar properties including chemical inertness and thermal stability.

YouTube - ‪3D Printer‬‏ - 0 views

  •  
    3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes.

UK scientists develop optimum piezoelectric energy harvesters - 2 views

  •  
    Piezoelectric energy harvesters are typically vibrating cantilevers, covered with a piezoelectric layer that converts mechanical strain to an electrical charge to power devices. Most developers cover the entire length of the cantilever with piezoelectric material in an attempt to maximise the conversion efficiency.

Study predicts nanoscience will greatly increase efficiency of next-generation solar cells - 0 views

  •  
    "As the fastest growing energy technology in the world, solar energy continues to account for more and more of the world's energy supply. Currently, most commercial photovoltaic power comes from bulk semiconductor materials. But in the past few years, scientists have been investigating how semiconductor nanostructures can increase the efficiency of solar cells and the newer field of solar fuels. "

US approves world's biggest solar energy project in California | KurzweilAI - 0 views

  •  
    The U.S. Department of Interior approved on Monday a permit for Solar Millennium, LLC to build the largest solar energy project in the world - four  plants at the cost of one billion dollars each - in southern California. The project is expected to generate up to 1,000 Megawatts of energy, enough electricity to annually power more than 300,000 single-family homes, more than doubling the solar electricity production capacity of the U.S. Once constructed, the Blythe facility will reduce CO2 emissions by nearly one million short tons per year, or the equivalent of removing more than 145,000 cars from the road. Additionally, because the facility is "dry-cooled," it will use 90 percent less water than a traditional "wet-cooled" solar facility of this size. The Blythe facility will also help California take a major step toward achieving its goal of having one third of the state's power come from renewable sources by the year 2020. The entire Blythe Solar Power Project will generate a total of more than 7,500 jobs, including 1,000 direct jobs during the construction period, and thousands of additional indirect jobs in the community and throughout the supply chain. When the 1,000 MW facility is fully operational it will create more than 220 permanent jobs. Adapted from materials provided by Solar Millennium, LLC.

The future of metabolic engineering: Designer molecules, cells and microorganisms - 0 views

  •  
    ScienceDaily (Dec. 3, 2010) - Will we one day design and create molecules, cells and microorganisms that produce specific chemical products from simple, readily-available, inexpensive starting materials? Will the synthetic organic chemistry now used to produce pharmaceutical drugs, plastics and a host of other products eventually be surpassed by metabolic engineering as the mainstay of our chemical industries? Yes, according to Jay Keasling, chemical engineer and one of the world's foremost practitioners of metabolic engineering.

RepRapWiki - 0 views

  •  
    RepRap is a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap can print those parts, RepRap is a self-replicating machine - one that anyone can build given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend...RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too.Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. Our community portal and New Development pages have more information on how to get involved. Use the links below and on the left to explore the site contents. You'll find some content translated into other languages.RepRap is described in the video on the right.

People who really identify with their car drive more aggressively, study finds - 0 views

  •  
    The studies found:People who perceive their car as a reflection of their self-identity are more likely to behave aggressively on the road and break the law.People with compulsive tendencies are more likely to drive aggressively with disregard for potential consequences.Increased materialism, or the importance of one's possessions, is linked to increased aggressive driving tendencies.Young people who are in the early stages of forming their self-identity might feel the need to show off their car and driving skills more than others. They may also be overconfident and underestimate the risks involved in reckless driving.Those who admit to aggressive driving also admit to engaging in more incidents of breaking the law.A sense of being under time and pressure leads to more aggressive driving.
