Scientists ‘cut’ grafeenvormen for construction of nanomachines




Scientists have found a way to make all kinds of layers of graphene on a nanoscale. This form of ‘kirigami “the cut variant of origami, to make it easier to create all kinds of nanomachines with graphene.

The researchers are working at Cornell University in the United States and have their findings managed to publish in the authoritative scientific journal Nature. In their experiments, they showed that it is possible to cut shapes in layers of graphene which are only 10 microns thick. According to the scientists with their methods possible to cut graphene in forms as if it were paper.

In order to obtain graphene in the desired shape, use is made of a laser. This, the researchers from Cornell University, what they call ‘kirigami’; that’s origami, but then cut instead of folding. In one of the demonstrations they showed a layer of graphene to cut a feather. It showed why graphene has interesting properties: the material was first completely ‘wrinkled’, but then bounced right back again. The example shows how graphene is strong, says one of the researchers.

The goal of such research is to find a way to build nanomachines based on graphene. The methodology of Cornell University would be easier to build such devices. When the kirigami can be used on a nanoscale in the practice is not yet clear. However, the scientists have received a scholarship from the US Department of Defense to do more research.
