  • 2. OverviewIntroduction to GrapheneGraphene is an allotrope of carbon, whose structure is one-atom-thickplanar sheets of sp2-bonded carbon atoms that are densely packed in ahoneycomb crystal lattice. The term graphene was coined as acombination of graphite and the suffix -ene by Hanns-Peter Boehm, whodescribed single-layer carbon foils in 1962. Graphene is most easilyvisualized as an atomic-scale chicken wire made of carbon atoms and theirbonds. The crystalline or "flake" form of graphite consists of manygraphene sheets stacked together.The carbon-carbon bond length in graphene is about 0.142 nanometers.Graphene sheets stack to form graphite with an interplanar spacing of0.335 nm, which means that a stack of 3 million sheets would be only onemillimeter thick. Graphene is the basic structural element of some carbonallotropes including graphite, charcoal, carbon nanotubes and fullerenes. Itcan also be considered as an indefinitely large aromatic molecule, thelimiting case of the family of flat polycyclic aromatic hydrocarbons. TheNobel Prize in Physics for 2010 was awarded to Andre Geim andKonstantin Novoselov "for groundbreaking experiments regarding the two-dimensional material graphene". © 2011 Gridlogics.

  • 3. Benefits of GrapheneResearch and development around graphene is moving ahead yielding newforms, new applications and new material based on this unique structureand we take a look into this breakthrough in science and the innovationthat surrounds it as it promises to be a large part or small devices of thefuture. Transistors made using these graphenes can work faster than those made of silicon, in electronics. Computer chips should be very much thin in order to work faster and also to use less electricity. As a result, the distance to be travelled by the electrons will be reduced. This can in turn improve the speed of the computer. Since graphene transistors will be small in size, it can be of much use for this purpose. Graphene electrodes can now be flexible and transparent. It is possible to produce computer monitors which are having thickness as like a paper and are transparent. Image Source: Graphene is being used to conduct researches for knowing more http://www.nature.com/news/2009 about two dimensional materials having special features. /090114/full/news.2009.28.html Graphene provides scope for researches that can chance the path of quantum physics. When mixed with graphene, plastic also turns as conductor for electricity. At the same time, it would also tolerate heat. Based on this fact, harder mixed materials can be produced in future. Along with having thin shape, they also have quality of expanding. These mixed materials may be used extensively in the making of satellites, air planes, solar panels, cars and others. Graphene will be 98% transparent and at the same time will absorb electricity well. Based on this feature, transparent touch screens, light panels and mobile phones can be made. Graphene is used in LEDs for brake Because of special structure of graphene, sensitive sensors can lights, stoplights, flashlights be manufactured. They can detect pollution even at the smallest Image Source: range. http://products.cvdequipment.com/ applications/4/ © 2011 Gridlogics. All Rights Reserved.

  • 7. Publication TrendWhat has been the IP publication trend for Graphene?Patents related to Graphene can be traced back to before 1950, although the number of filingsremained relatively low all the way up till the year 2000. Noticeably there was a very large spike inpublications for 2010 which saw more than 600 patents published during the year.Just a month and a half into 2011 and we are already seeing around 100 patents. It’s clear that thistechnology picked up slowly, grew consistently and has now reached new heights and is evidently onan upward trend.How we did it?Once the patents were populated in Patent iNSIGHT Pro, the publication trend chart was generated on a singleclick using the dashboard tool. © 2011 Gridlogics.

Compounds compositions systems and methods for the chemical and electrochemical modification of the electronic structure of graphene and especially epitaxial graphene (EG) are presented. Beneficially such systems and methods allow the large-scale fabrication of electronic EG devices. Vigorous oxidative conditions may allow substantially complete removal of the EG carbon atoms and the generation of insulating regions; such processing is equivalent to that which is currently used in the semiconductor industry to lithographically etch or oxidize silicon and thereby define the physical features and electronic structure of the devices. However graphene offers an excellent opportunity for controlled modification of the hybridization of the carbon atoms from sp2 to sp3 states by chemical addition of organic functional groups.

  • 63. A detection system in which a single sensor is employed to detect an extensive range of a parameter. The output signal from the sensor is fed to the input of the electrical circuit having a feedback loop wherein the electrical circuit has a non-linear transfer characteristic. The non- linear transfer characteristic is achieved by changing the behavior of the feedback loop of the electrical circuit at a predetermined level of input signal. The output of the circuit has a proportional relationship with the input until the input signal reaches this predetermined value whereupon the behaviors of the feedback loop changes and the relationship of the output to the input of the circuit changes. While the input signal is above the predetermined value the output of the circuit has a linear but disproportionate relationship with the input at a gradient different to that when the input signal is below the predetermined value.
