Graphene applications in mobile communication

No matter what the wireless standard, signal processing could not be done without the filtering of frequencies. Micro-acoustic piezoelectric resonators are the dominant technology in the market for this purpose. Theory predicts excellent oscillation characteristics for these resonators, if the electrode used for the excitation of the oscillation becomes very light. And the lightest conceivable electrode is electrically conductive graphene.

You can't play checkers with charge ordering

Physicists observed the shape of a strange phenomenon that interferes with high-temperature superconductivity called charge ordering, discovering that it is stripy, not checkered, and settling a long-standing debate in the field.
