Researchers part water: 'electric prism' separates water's nuclear spin states Posted: 08 Sep 2014 09:10 AM PDT Using an 'electric prism,' scientists have found a new way of separating water molecules that differ only in their nuclear spin states and, under normal conditions, do not part ways. Since water is such a fundamental molecule in the universe, the recent study may impact a multitude of research areas ranging from biology to astrophysics.

Doped graphene nanoribbons with potential Posted: 08 Sep 2014 05:33 AM PDT Graphene possesses many outstanding properties: it conducts heat and electricity, it is transparent, harder than diamond and extremely strong. But in order to use it to construct electronic switches, a material must not only be an outstanding conductor, it should also be switchable between "on" and "off" states. This requires the presence of a so-called bandgap, which enables semiconductors to be in an insulating state. The problem, however, is that the bandgap in graphene is extremely small. Empa researchers from the "nanotech@surfaces" laboratory thus developed a method some time ago to synthesize a form of graphene with larger bandgaps by allowing ultra-narrow graphene nanoribbons to "grow" via molecular self-assembly.
