Graphene is one of the most recently-discovered materials in the scientific community, at the tender age of 5 years old. In spite of only being discovered in 2004, it is already considered to be one of the possible replacements for silicon, the chemical that at this point provides the basis for the world of electroni... |

The economic factor is one of the main things that dictate whether an oil well will be opened or not, economists say. Experts at the Rice University have recently entered a new research effort, aimed at producing a nanometer-thick layer of graphene that would constitute an additive for average drilling bits. The inno... |
