    New Form of Carbon Is Super-Strong, Can Kick Diamond’s Ass

    Carbon is kind of awesome: other than the element that, you know, is what all organic life on earth is based on, it's now even more than sparkly, gorgeous diamonds and many an artist's best friend in graphite and charcoal. In a new paper, scientists theorize that double- or triple-bonded carbon atoms will make the world's strongest material.

    Let’s Go Ahead And Add “Makes Lasers” To Graphene’s Already Impressive Resume

    We get it, graphene -- you're amazing. We've more or less accepted that there's nothing graphene can't do, but that doesn't stop us from being amazed every time it does something new. It's newest feat is that the super-material can be used to create ultrashort-pulse lasers. Damn, graphene. Save some cool stuff for the other materials to do.

    Is There Anything It Can’t Do? Researchers Propose Artificial Muscles Made Of Graphene

    We've seen graphene do some amazing things, but every time we think we've seen the coolest potential application for the wonder-substance, it continues to impress. The latest impressive feat? Researchers at Duke University have taken advantage of one of the things that makes graphene difficult to work with -- the fact that it "crumples" easily -- and turned that quality into a desirable trait that they can control. By running the show as graphene crumples and flattens out, the team could one day use the substance to form artificial muscles that expand and contract on command.

    New Super Hard Form of Carbon Discovered Can Dent Diamonds

    Move over, diamonds -- there's a new toughest form of carbon in the world. A new form of the element that blends both crystalline and chaotic structures has been created by researchers at the Carnegie Institution, and it's so durable it can put a dent in the former world's hardest substance and automatic relationship apologizer.

    Graphene Reacts Based on Material Beneath It, Continues to Amaze

    Most compositions react to different chemicals due to the nature of their atomic structure and other similar factors. This, apparently, is one of those things that doesn't necessarily apply to graphene. When layered on top of various materials, a one-atom-thick sheet of the stuff can exhibit drastically different properties. This includes both how the graphene reacts chemically with other materials introduced to the sheet and how it conducts electricity.

    Graphene Boosts Artificial Photosynthesis Efficiency, This Is Getting Ridiculous

    We already know that graphene is a wonder-material, so it's no surprise that it has yet another superpower. It is, however, a little bit of a surprise that there are still superpowers left that it isn't yet known to have. A recent study by a team of scientists from the Korea Research Institute of Chemical Technology, and Ewha Womans University, both in South Korea, have found that graphene has potential in increasing the efficiency of artificial photosynthesis. This is probably thanks in part to its ability to generate electricity when struck by light, and the same qualities that make it great for supercapacitors.

    Sheets of Graphene can Patch Their Own Holes, Will the Wonders Never Cease?

    The "God-particle" has been getting all the attention lately, but nevermind that for a moment. We've got an up-and-coming God-material on our hands. Graphene -- already proven to have the strength steel in sheets as thin as paper, uses in super-powerful, flexible capacitors, applications in improving the efficiency of desalination by a factor of 100, and the ability to generate electricity when struck by light -- has just demonstrated a new miraculous quality: Sheets of graphene can patch their own holes. It seems that the question of "is there anything graphene can't do?" is becoming less and less rhetorical with each passing day.

    Graphene Can Improve Desalination Efficiency by Several Orders of Magnitude, Can Do Pretty Much Anything

    Graphene. It can be stronger than steel and thinner than paper. It can generate electricity when struck by light. It can be used in thin, flexible supercapacitors that are up to 20 times more powerful than the ones we use right now and can be made in a DVD burner. It's already got an impressive track record, but does it have any more tricks up its sleeve? Apparently, yes. According to researchers at MIT, graphene could also increase the efficicency of desalination by two or three orders of magnitude. Seriously, what can't this stuff do?

    Flexible Graphene Supercapacitors Can Be Made With a DVD Burner

    If it wasn't enough that graphene is photovoltaic and that it can be as strong as steel in sheets as thin as paper, it turns out that graphene has yet another useful application; graphene can be used to make thin, flexible supercapacitors that are 20 times more powerful than your average electrochemical variety. On top of that, the production process can be performed with a DVD burner. The applications, as you might imagine, are plentiful.

    Graphene Creates Electricity When Struck by Light

    According to researchers at MIT, graphene generates an electrical current when struck by light. If you aren't familiar, graphene is something of a miracle material. It's basically a one-atom thick sheet of carbon that manages to come in sheets as thin as paper while being as strong as steel. That's already pretty impressive, so the ability to generate electricity from light is just icing on the cake.

    The way it works is that when hit by light, pretty much any kind of light, graphene generates a hot carrier response. This means that the electrons of the molecules in the graphene sheet gain enough energy to start moving (creating the current) but the carbon underneath still manages to stay cool.

    Aussies Unveil Graphene That’s Stronger Than Steel, Thin as Paper

    The University of Technology Sydney announced yesterday that they have created sheets of graphene, specially processed graphite, that is stronger than steel, but has the thickness of paper. The new material has incredible properties, as described on the UTS website:
    Using a synthesised method and heat treatment, the UTS research team has produced material with extraordinary bending, rigidity and hardness mechanical properties. Compared to steel, the prepared [graphene paper] is six times lighter, five to six times lower density, two times harder with 10 times higher tensile strength and 13 times higher bending rigidity.

    Graphene Researchers Win 2010 Nobel Physics Prize

    Russian-born physicists Konstantin Novoselov and Andre Geim, both faculty members at the University of Manchester, have won the 2010 Nobel Prize in Physics for their work with graphene, which is an arrangement of carbon consisting of a flat, atom-thick layer in a honeycomb-like lattice. In 2004, Novoselov and Geim discovered a low-tech but highly effective way to produce graphene flakes: With Scotch tape. By putting tape on a piece of graphite and repeatedly peeling away, you can create a layer of graphene. Now known as the so-called "Scotch tape technique," according to Dr. Geim, this discovery has had theoretical as well as practical implications: New Scientist reports that it wasn't previously known that such two-dimensional sheets would be stable.
