Read morePhysicists build stable diffraction structure in single-layer graphene
Quantum physics tell us that even massive particles can behave like waves, as if they could be in several places at once. This phenomenon is typically proven in the diffraction of a matter wave at a grating. In a European collaboration, researchers carried this idea to the extreme and observed the delocalization of molecules at the thinnest possible grating, a mask milled into a single layer of atoms.

'Flocking' or 'swarming' behavior is omnipresent in the living world, observed in birds, fish, and even bacteria. Strikingly similar collective action can also be seen in biomolecules within and between cells. New insights into how this action is coordinated at the biomolecular level are emerging from studies of a model system based on actin filaments.

Read moreSelf-assembled aromatic molecular stacks, towards modular molecular electronic components
Researchers describe the electron-transport properties of aromatic stacks aligned in a self-assembled cage, using a scanning tunneling microscope (STM) based break-junction method. Both identical and different modular aromatic pairs are non-covalently bound and stacked within the molecular scaffold leading to a variety of fascinating electronic functions.
