Scientists from Columbia University have reportedly proven a 30-year-old theory called “the even-denominator fractional quantum Hall state” and established bilayer graphene as a promising platform that could lead to quantum computation. The team observed an intensely studied anomaly in condensed matter physics—the even-denominator fractional quantum Hall (FQH) state—via transport measurement in bilayer graphene.
Researchers have created a graphene nanoribbon sensor which can measure high vacuum pressures. The Researchers synthesized a mixture of graphene nanoribbons (of varying size and chemical composition) from a combination of multi-walled carbon nanotubes, sulphuric acid and phosphoric acid in a chemical exfoliation approach. The result was a mixture of several graphene nanoribbons which were separated and purified ready for device implementation and testing. The Researchers also synthesized graphene oxide through a modified Hummers’ method for use as a reference material.
Graphene’s two-dimensional physical attributes have offered some of its most attractive properties. But over the past couple of years, it’s been shown that adding a little wrinkle to the material—effectively making it three-dimensional—offers some new possibilities for the wonder material in wearable electronics and biological or dispensable sensors. However, adding those wrinkles comes at a price: the manipulation is performed under harsh conditions that compromise precision or tunability.
