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

A study appearing Feb. 10 in Science Express calculates the world's total technological capacity to store, communicate and compute information, part of a Special Online Collection: Dealing with Data. The study by the USC Annenberg School for Communication & Journalism estimates that in 2007, humankind was able to store 2.9 × 1020 optimally compressed bytes, communicate almost 2 × 1021 bytes, and carry out 6.4 × 1018 instructions per second on general-purpose computers. General-purpose computing capacity grew at an annual rate of 58%. The world's capacity for bidirectional telecommunication grew at 28% per year, closely followed by the increase in globally stored information (23%). Humankind's capacity for unidirectional information diffusion through broadcasting channels has experienced comparatively modest annual growth (6%). Telecommunication has been dominated by digital technologies since 1990 (99.9% in digital format in 2007), and the majority of our technological memory has been in digital format since the early 2000s (94% digital in 2007).

"In 2009, the scientific literature caught up with what top climate scientists have been saying privately for a few years now: * Many of the predicted impacts of human-caused climate change are occurring much faster than anybody expected - particularly ice melt, everywhere you look on the planet. * If we stay anywhere near our current emissions path, we are facing incalculable catastrophes by century's end, including rapid sea level rise, massive wildfires, widespread Dust-Bowlification, large oceanic dead zones, and 9°F warming - much of which could be all but irreversible for centuries. And that's not the worst-case scenario! * The consequences for human health and well being would be extreme. That's no surprise to anybody who has talked to leading climate scientists in recent years, read my book Hell and High Water (or a number of other books), or followed this blog. Still, it is a scientific reality that I don't think more than 2 people in 100 fully grasp, so I'm going to review here the past year in climate science. I'll focus primarily on the peer-reviewed literature, but also look at some major summary reports."

During the past 15 years, the World Wide Web has created remarkable new methods for harnessing the creativity of people in groups, and in the process has created powerful business models that are reshaping our economy. As the Web has undermined old media and software companies, it has demonstrated the enormous power of a new approach, often referred to as Web 2.0. In a nutshell: the secret to the success of bellwethers like Google, Amazon, eBay, Craigslist, Wikipedia, Facebook, and Twitter is that each of these sites, in its own way, has learned to harness the power of its users to add value to-no, more than that, to co-create-its offerings.

To know what the most important virtue of our age is we need to have at least a basic understanding of our age. Our era is becoming increasingly characterized by uncertainty. Fortunately or unfortunately, more than a cursory elucidation of our situation is beyond the scope of this essay. There are geopolitical, economic, technological and environmental trends worth mentioning. When the more philosophical portion of this  discourse arrives I will argue that the virtue of wisdom underlies the meaningfulness and efficacy of all other virtues, and this in broad strokes is primarily due to (1) the aforementioned instability in our surroundings ; (2) the relationship between the deontological and virtue; and (3) the nature of agency itself.  Whether uncertainty itself can provide an ethical foundation for us to elaborate on will be a separate question, and finally I speculate on where wisdom leads us in the context of a philosophy that is politically active and not doomed to irrelevance to and by the larger population.

There are differences between the group's demonstrations. For crystals, Tittel's group used thulium-doped lithium niobate, whereas Gisin's group opted for neodymium-doped yttrium silicate. In addition, a different type of laser set-up has favoured Gisin's group, which reports a maximum storage time of some 200 ns at an efficiency of more than 20%; Tittel's group reports a storage time of 7 ns at an efficiency of 2%. On the other hand, the quantum memory of Tittel's group functions at a bandwidth of 5 GHz - some 40 times greater than Gisin's group - which means, potentially, far more information could be sent in the same time.

Social media present risks and benefits to children but parents who try to secretly monitor their kids' activities online are wasting their time, says Larry D. Rosen, Ph.D., professor of psychology at California State University, Dominguez Hills. Rosen identifies potential adverse effects of social media, including: Teens who use Facebook more often show more narcissistic tendencies, while young adults who have a strong Facebook presence show more signs of other psychological disorders, including antisocial behaviors, mania, and aggressive tendencies. Daily overuse of media and technology has a negative effect on the health of all children, especially preteens and teenagers, by making them more prone to anxiety, depression, and other psychological disorders, and making them more susceptible to future health problems. Facebook can be distracting and can negatively impact learning. Studies found that middle school, high school and college students who checked Facebook at least once during a 15-minute study period achieved lower grades. Rosen says new research has also found positive influences linked to social networking, including: Young adults who spend more time on Facebook are better at showing "virtual empathy" to their online friends. Online social networking can help introverted adolescents learn how to socialize. Social networking can provide tools for teaching in compelling ways that engage young students. "If you feel that you have to use some sort of computer program to surreptitiously monitor your child's social networking, you are wasting your time. Your child will find a workaround in a matter of minutes," he says. "You have to start talking about appropriate technology use early and often and build trust, so that when there is a problem, whether it is being bullied or seeing a disturbing image, your child will talk to you about it."

What does the future of science look like? About a year ago, I was asked this question. My response then was: Transdisciplinary collaboration. Researchers from a variety of domains-biology, philosophy, psychology, neuroscience, economics, law-all coming together, using inputs from each specialized area to generate the best comprehensive solutions to society's more persistent problems. Indeed, it appears as if I was on the right track, as more and more academic research departments, as well as industries, are seeing the value in this type of partnership. Now let's take this a step further. Not only do I think we will be relying on inputs from researchers and experts from multiple domains to solve scientific problems, but I see society itself getting involved on a much more significant level as well. And I don't just mean science awareness. I'm talking about actually participating in the research itself. Essentially, I see a huge boom in the future for Citizen Science.

DARPA, the Pentagon's advanced concepts think-tank, is looking to take propaganda to the next level, and they're hoping to do so by controlling the very way their targets perceive and interpret the flow of incoming information.

Today at the Techonomy conference in Lake Tahoe, CA, the first panel featured Google CEO Eric Schmidt. As moderator David Kirkpatrick was introducing him, he rattled off a massive stat. Every two days now we create as much information as we did from the dawn of civilization up until 2003, according to Schmidt. That's something like five exabytes of data, he says. Let me repeat that: we create as much information in two days now as we did from the dawn of man through 2003.

When we talk about participation, we have to be a bit more specific. On the publishing side, there's clearly more participation than we've ever seen in the past. But in order for this tidal wave of information to be useful, we need to be able to separate fact from fiction. We need to encourage participation on the receiving end. What we need is evaluating participation. With the breadth of niche information and sources we have the ability to get at the best of what is known on a myriad of topics and contexts. Every niche has its experts and its hacks, its enthusiasts and detractors. But for the remaining 95% of us who are not subject matter experts, deriving the accurate or useful information from the sea of what is available can be complicated, time-consuming and simply unverifiable. We need a way to quantify the value of information, or more specifically, the veracity of information.
