Will your future computer be made using bacteria?

Scientists are making graphene easier and more environmentally friendly to produce

12-Jul-2019

In order to create new and more efficient computers, medical devices, and other advanced technologies, researchers are turning to nanomaterials: materials manipulated on the scale of atoms or molecules that exhibit unique properties. Graphene--a flake of carbon as thin as a single later of ...

Producing Graphene from Carbon Dioxide

Direct Synthesis of Technological Material Graphene from Greenhouse Gas Carbon Dioxide

10-Jul-2019

The general public knows the chemical compound of carbon dioxide as a greenhouse gas in the atmosphere and because of its global-warming effect. However, carbon dioxide can also be a useful raw material for chemical reactions. A working group at Karlsruhe Institute of Technology (KIT) has now ...

Playfully discover atom manipulation

Online simulation game makes graphene research available to the public

10-Jul-2019

The team of Toma Susi at the University of Vienna uses a state-of-the-art electron microscope, the UltraSTEM, to manipulate strongly bound materials with atomic precision. Since the instruments used are fully computerized, it is possible to show in a simulation how researchers actually use them. ...

Branching out: Making graphene from gum trees

Cost-effective and eco-friendly way of producing graphene using eucalyptus trees

26-Jun-2019

Graphene is the thinnest and strongest material known to humans. It's also flexible, transparent and conducts heat and electricity 10 times better than copper, making it ideal for anything from flexible nanoelectronics to better fuel cells. The new approach by researchers from RMIT University ...

Strain enables new applications of 2D materials

Application of mechanical strain appears to manipulate the conductivity of low-dimensional materials

23-May-2019

Superconductors' never-ending flow of electrical current could provide new options for energy storage and superefficient electrical transmission and generation, to name just a few benefits. But the signature zero electrical resistance of superconductors is reached only below a certain critical ...

Stickier than expected: Hydrogen binds to graphene in 10 femtoseconds

07-May-2019

Graphene is celebrated as an extraordinary material. It consists of pure carbon, only a single atomic layer thick. Nevertheless, it is extremely stable, strong, and even conductive. For electronics, however, graphene still has crucial disadvantages. It cannot be used as a semiconductor, since it ...

Decoupled graphene thanks to potassium bromide

02-May-2019

The use of potassium bromide in the production of graphene on a copper surface can lead to better results. When potassium bromide molecules arrange themselves between graphene and copper, it results in electronic decoupling. This alters the electrical properties of the graphene produced, bringing ...
