Scientists combined buckyballs, which resemble tiny soccer balls made from 60 carbon atoms, with graphene, a single layer of carbon, on an underlying surface. Positive and negative charges can transfer between the balls and graphene depending on the nature of the surface as well as the structural order and local orientation of the carbon ball. […]
Researchers at MIT and Harvard University have found that graphene can be tuned to behave at two electrical extremes: as an insulator, in which electrons are completely blocked from flowing; and as a superconductor, in which electrical current can stream through without resistance.
The Korean state-run Electronics and Telecommunications Research Institute (ETRI) announced the development of a graphene-based optical modulator device capable of performing arithmetic and remembering it at the same time. According to ETRI, the device works much like a human brain. The institute said its researchers have artificially recreated neural synapses in the device. It added […]
A sandwich of two graphene layers can conduct electrons without resistance if they are twisted at a ‘magic angle’’, physicists have discovered. The finding could prove to be a significant step in the decades-long search for room-temperature superconductors.
Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory are part of a scientific collaboration that has identified a new electrocatalyst that efficiently converts CO2 to carbon monoxide (CO), a highly energetic molecule.
Fraunhofer scientists have developed biosensors with graphene electrodes, produced cheaply and simply by roll-to-roll printing. A system prototype for mass production has already been established. This may change the current situation in which cell-based biosensors can be quite expensive to make, which often prevents them from being used. Cost factors for sensors that perform measurements […]
Scientists from CSIR–Central Electrochemical Research Institute (CSIR-CECRI) and CSIR–Central Salt and Marine Chemicals Research Institute (CSIR-CSMCRI) in India have collected discarded lithium-ion batteries and created reduced graphene oxide from them. The material reportedly showed high specific capacity at low current, making it an ideal material for next generation high-performance supercapacitors.
Researchers at the Korean Advanced Institute of Science and Technology (KAIST) have developed a graphene-based aqueous hybrid capacitor that is stable, safe and boasts high energy and power densities, in addition to recharging in under 30 seconds.

Foldable phones will be on the market within five years, according to the Graphene Flagship programme. As Ivor Bennett reports, the miracle material will revolutionise not only mobiles but medicine too.
