Researchers have developed a revolutionary method to intricately grow and protect some of the world's most exciting nanomaterials—graphene and carbon nanotubes (CNT).

When curved and rolled into cylinders, thin graphene layers form CNT structures. These rolled sheets of carbon can be a thousandth of the diameter of human hair and possess extraordinary properties such as extreme electrical conduction, or 100 times the strength of high tensile steel. Although widely regarded as the key to developing future batteries and supercapacitor technologies, CNTs are plagued with environmental 'poisoning' which causes the materials to lose their catalyst properties.

In a paper published by the journal Carbon, researchers from the University of Surrey detail their new method for covering the CNTs' catalyst by using a that is configured to allow carbon diffusion and thus can be used to protect the catalyst from . The technique allows the catalyst to be transported, stored or accurately calibrated for future use.

This is a very big development.  Graphene is ready for prime time. To read more, click here.
