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.
Amber has been appreciated by mankind for its color and natural beauty since the Neolithic Era. However, amber can also be a gemstone for physics and chemistry research on glasses.
