Atomic-scale Control of Graphene Magnetism by Using Hydrogen Atoms


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.

Fluorescence Tracking of Genome Release during Mechanical Unpacking of Single Viruses


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.
