Graphene Walls – Walls of Graphene

Putting 100 trillion Field Effect Transistors (FETs) on a one square centimeter chip may become possible using graphene walls. The term “graphene walls” in this context describes tiny strips or “nano-ribbons” of carbon atoms. Other researchers have developed ideas for creating cheap and flexible lighting and display substrates made of graphene components embedded in plastic. In this context, “walls made of graphene” would imply household surfaces (walls, ceilings, floor, furniture…) that can provide both lighting and display information. These two different technologies seem to have a future of convergence.

Calculations by Rice theoretical physicist Boris Yakobson, Assistant Professor Feng Ding of Hong Kong Polytechnic and their collaborators showed substrates not only of diamond but also nickel could chemically bind the edge of a strip of a graphene nanoribbon. Because the contact is so slight, the graphene walls retain nearly all of their inherent electrical or magnetic properties.

And because they’re so thin, Yakobson and Ding calculated a theoretical potential of putting 100 trillion graphene wall field-effect transistors (FETs) on a square-centimeter chip.

Super Material Will Make Lighting Cheaper and Fully Recyclable – [expertvar.se]

With the use of the new super material graphene, Swedish and American researchers have succeeded in producing a new type of lighting component. It is inexpensive to produce and can be fully recycled.

The invention, which paves the way for glowing wallpaper made entirely of plastic, for example, is published in the scientific journal ACS Nano by scientists at Linköping University and Umeå University, in Sweden, and Rutgers, The State University of New Jersey.

Wallpaper doubles as television – [theage.com.au]

JAPANESE scientists are developing a wallpaper that can be turned into a television screen, with the help of nanotechnology.

The living room of the future could be coated in the revolutionary wallpaper, thanks to the efforts of researchers at Toshiba. As well as being able to turn entire walls into a screen, the flexible paper can be adjusted to show images that fit the home owner’s mood.

The breakthrough in wall coverings is the result of improvements in organic electroluminescence (OLED) screen technology that enables the paper to emit light.
