The new centimeter-size crystals were produced via the utilization of practically nothing but surface oxygen and thin sheets of copper. The graphene crystals

The discovery: the many impressive properties of graphene, such as extreme conductivity and “complete” transparency for example, are apparently completely unaffected by the application of thin silicon film. The discovery

The new research has found that the sharp edges of graphene sheets can easily pierce cell membranes, and then after piercing the membranes, be pulled into the cell where they then disrupt normal cellular

The general drive in the solar energy technology industry has been towards the development of higher solar cell efficiencies and lowered manufacturing costs, but are there other avenues of improvement worth exploring? Such as the development of ultra-thin, ultra-lightweight solar cells? That’s exactly what new research from MIT

Researchers in the University of Florida’s physics department have reportedly set a new record for graphene solar cell efficiency. Here’s more from the University of Florida: Graphene solar cells are one of industry’s great hopes for cheaper, durable solar power
