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 […]
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 Graphene Flagship has achieved most of its objectives and milestones and delivered exceptional results with significant immediate or potential impact. This is the conclusion of the European Commission in its interim review report of the project’s first year following the two-and-half-year ramp-up phase. Having reported over 600 scientific publications, 37 patent applications, 17 products […]
Many types of sensor now use graphene as the response material and has become a hot area of graphene research. Despite not being the most obvious use of graphene to outsiders, it is an area in which a lot of research is being undertaken and commercialized. A new addition to the graphene sensor family has […]
A team led by Cory Dean, assistant professor of physics at Columbia University, and James Hone, Wang Fong-Jen Professor of Mechanical Engineering at Columbia Engineering, has definitively observed an intensely studied anomaly in condensed matter physics—the even-denominator fractional quantum Hall (FQH) state—via transport measurement in bilayer graphene. The study is published online today in Science.
EPFL scientists have greatly improved the operational stability of perovskite solar cells by introducing cuprous thiocyanate protected by a thin layer of reduced graphene oxide. Devices lost less than 5% performance when subjected to a crucial accelerated aging test during which they were exposed for more than 1000 hours to full sunlight at 60°C.
Swinburne will create the world’s first graphene certification centre as part of its revolutionary research into graphene and digital manufacturing processes.
Graphene, a sheet of carbon just one atom thick, can be forged into 3D shapes using a pulsed laser beam, according to new experiments by researchers in Finland and Taiwan. The technique, dubbed optical forging, works thanks to the laser light expanding local areas in graphene, and it could be used to fabricate 3D architectures […]
James Baker, Business Director for Graphene at The University of Manchester, talks to AZoNano about the current state of the graphene market and the key next steps needed.
