Overview of dynamic graphene oxide sorting: (a) The system uses electron beams on silicon nitride membranes to create electric field patterns that generate opposing forces on graphene oxide sheets ...

Meret Aeppli, Sébastien Giroud, Sanja Vranic, Andreas Voegelin, Thomas B. Hofstetter, Michael Sander, Thermodynamic controls on rates of iron oxide reduction by extracellular electron shuttles, ...

We report on a large electric-field response of quasi--two-dimensional electron gases generated at interfaces in epitaxial heterostructures grown from insulating oxides. These device structures are ...
