Advances in solar cell technologies are rapidly changing the landscape of global energy supply. Conversion efficiencies are however ultimately limited to a maximum ~40% in conventional silicon-based solar cell designs.
We report isolation of antimonene, a new allotrope of antimony that consists on a single layer of atoms. Graphene is well-known by its tremendous potential applications; however the lack of electronic gap limits its use in the electronics technology.
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.

Electrostatics is one of the fundamental driving forces of the interaction between biomolecules in solution. In particular, the recognition events between viruses and host cells are dominated by both specific and non-specific interactions and the electric charge of viral particles determines the electrostatic force component of the latter.
