Researchers are discovering that graphene stronger than steel in protection against bullets




The US researchers to conduct ballistic tests mini to prove how effective use of material graphene shield protection against bullets, and that by throwing balls of tiny silicon dioxide, also known as silica, on a sheet of graphene.

In the magazine “Saans” Science Scientific, researchers reported that the thickness of the layers of corn this article can be stronger than steel when it comes to absorbing effects.

Graphene consists of a single sheet of atoms arranged in a honeycomb cell shape, and characterized this article as a thin, powerful, flexible and electrically conductive.

And use Jae-Hwang Lee of the University of Massachusetts at Amherst and his colleagues lasers to control silica tiny bullets penetrate a sheet of graphene thickness of 10 to 100 layer.

The researchers compared the kinetic energy balls before and after the break graphene sheets, and revealed the notes using an electron microscope that graphene is wasting energy by expansion in the form of a cone and then squandered in different directions.

Ballistic tests showed that the mini-strength, flexibility and rigidity extraordinary enjoyed by graphene allowed it to accommodate between 8 to 10 times the effects that can be carried by steel.

However, resulted in the way that was received graphene sheets tiny bullets also for a broader impact crater, which could be a potential defect in graphene. So Jae-Hwang suggested to me that the combination of graphene and other material or more may be a compound able to solve this problem.

In 2010, researchers sharing Andre Jiem and Konstantin Novoselov of the University of Manchester, United Kingdom, the Nobel Prize in Physics for their discovery of graphene material.

Another study published in the journal “Nature” Nature this week revealed that the graphene sheets to allow molecules to pass through a proton, a property that will improve the efficiency of hydrogen fuel cells.
