The journal Nature Communications published an article where scientists from Monash University showed a procedure that, for the first time, allow a three-dimensional shape of the graphene , as this is a two-dimensional carbon mesh since it is only one atom thick.

is a material incredibly durable, chemically stable, an excellent conductor of electricity, which was only discovered in 2004 and earned its creators the Nobel Prize for Physics in 2010 .

The potential of graphene that could range from printed circuits or serve as a basis for batteries with 10 times the current capacity , to prevent theft or increase the speed of the Internet (more above is repair only , so it could be used to regenerate tissues).

The technical team of scientists, led by Professor Dan Li – for molding three-dimensional graphene was inspired by nature, and would mimic the design incredibly efficient, because it generates a very strong and lightweight structure, but also flexibly .

“When assembled three-dimensional structures with atomic layer graphene, they tend to form porous monoliths are fragile and do not have a good performance,” said Professor Li.

The method of the scientific graphene would create blocks that would be lighter than air, capable of withstanding 50,000 times its own weight, extremely resilient, could recover from an 80% deformation, and very good conductors of electricity.
