Scientists have created a new graphene nanostructure called the graphene nanomesh (GNM). The new structure is able to open up a band gap in a large sheet of graphene to create a highly uniform continuous semiconducting thin film. The concept of the GNM therefore points to a clear pathway towards practical application of graphene as a semiconductor material for future electronics.

To monitor the real-time performance of bone implants is the challenge of “Smart Hip,” an innovative medical device that aims to reduce the number of surgical interventions in the hip area and regenerate bone tissue by using non-evasive methods. The device — developed by an engineering doctoral student in Portugal — has already been successfully tested on animals.

Mechanical engineers have fabricated an ultra sharp, diamond-like carbon tip possessing such high strength that it is 3,000 times more wear-resistant at the nanoscale than silicon. The end result is a diamond-like carbon material mass-produced at the nanoscale that doesn’t wear.
