Neither of the earlier observations was sufficient to launch the "graphene gold rush" that awaited macroscopic samples of extracted atomic planes. One of the first patents pertaining to the production of graphene was filed in October 2002 and granted in 2006. [24] It detailed one of the first large scale graphene production processes.
In 2015, a coiled form of graphene was discovered in graphitic carbon (coal). The spiraling effect is produced by defects in the material's hexagonal grid that causes it to spiral along its edge, mimicking a Riemann surface, with the graphene surface approximately perpendicular to the axis. When voltage is applied to such a coil, current flows ...

Manfred von Ardenne invented and developed the flying-spot scanner, Europe's first fully electronic television camera tube. In Britain, the first television advertising and the first TV interview; 1931 The British engineer and inventor Alan Dower Blumlein (1903–1942) invents "Binaural Sound", today called "Stereo".
In 2009, the European Commission identified the need for Europe to address the big scientific and technological challenges of the age through long-term, multidisciplinary R&D efforts. One of the first European Future and Emerging Technologies (FET) Flagships, the Graphene Flagship was founded in October 2013. It was initially implemented as a ...

They also discovered a note from 1634 detailing a plague outbreak that killed more than 15,000 people in 1632-1633, which says almost 2,000 people were buried near St. Sebastian Spital, the site ...
This finding raises the possibility of carrying a drug in graphene droplets and releasing the drug upon reaching the targeted tissue by making the droplets change shape in a magnetic field. Another possible application is in disease detection if graphene is found to change shape at the presence of certain disease markers such as toxins. [22] [23]
