The incorporation of magnetism to the long list of graphene capabilities has been pursued since its first isolation in 2004. The use of spin as an additional degree of freedom would represent a tremendous boost to the versatility of graphene based devices. On one hand, spin information transfer or spin diffusion phenomena are favored by the expected long spin relaxation times of graphene carriers.

Viruses package their genome in a robust protein coat to protect it during transmission between cells and organisms. In a reaction termed uncoating, the virus is progressively weakened during entry into cells. At the end of the uncoating process the genome separates, becomes transcriptionally active, and initiates the production of progeny.

The response of superconducting devices to electromagnetic radiation is a core concept implemented in diverse applications, ranging from the currently used voltage standard to single photon detectors in astronomy. Suprisingly, a sufficiently high power subgap radiation may stimulate superconductivity itself.
The extraordinary strength, stiffness and lightness of graphene have generated great expectations of its application in flexible electro nics and as a mechanical reinforcement agent. However, the presence of lattice defects, un avoidable in sheets obtained by scalable routes, might degrade its mechanical properties.

Introducing a giant spin-orbit interaction on graphene/Ir(111) by intercalation of Pb. The intercalation of an ordered array of Pb atoms below graphene results in the appearance a series of equally spaced, sharp peaks in the differential conductance, as revealed by laterally resolved Tunnelling Spectroscopy at 4.6 K.
