Researchers in Italy have demonstrated the feasibility of quantum communications between high-orbiting global navigation satellites and a ground station, with an exchange at the single photon level over a distance of 20,000km. The milestone experiment proves the feasibility of secure quantum communications on a global scale, using the Global Navigation Satellite System (GNSS). It is reported in…
A Cost-Effective Solution to Tuned Graphene Production
Graphene has been called the miracle material but the single-atomic layer material is still seeking its place in the materials world. Now a method to make ‘defective’ graphene could provide the answer. Today (30 July), in the journal Nanotechnology, a team of researchers report that they have developed a simple electrochemical approach which allows defects to…
