Scientists report that they could observe experimentally the current flow along channels at the crystal surfaces of topological insulators. The channels are less than one nanometer wide and extend along atomic steps of the crystal lattice. The scientists demonstrated also how these steps can be introduced in any arrangement.

Read moreThe overall goals of EFSA's Nano Network are to provide a forum for dialogue among participants; build mutual understanding of risk assessment principles; enhance knowledge on and confidence in the scientific assessments carried out in EU; and to provide increased transparency in the current process among Member States and EFSA on nanotechnology. All this with the aim to raise the level of harmonisation of the risk assessments developed in the EU on nanotechnology.
