Researchers may have solved graphene’s production problems, cleared way for mass production

Researchers may have solved graphene’s production problems, cleared way for mass production | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it
A new method of producing graphene could be the major breakthrough scientists are looking for. If the new method of producing the material on a thin polymer works at commercial scale, it could clear the way for mass production.


The potential for reproducing and adopting these graphene-like carbon nanosheets for other markets is what makes this story interesting. The team didn’t say what percent of the graphene was defect-free, but they do claim that this new manufacturing method is far simpler and less prone to failure than previous types of graphene production.


If this technique can be adapted to semiconductors or other types of solar cells, it could be far more useful than any marginal gain in organic solar cell efficiency.


According to Dr. Han Ik Joh at the Korean Institute for Science and Technology, graphene can be produced in a similar manner to carbon fiber — and while that’s hardly cheap, it’s still better than our current methods.

Georgia Tech Researchers Show That Graphene Antennas Would Enable Terabit Wireless Downloads | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it
Researchers calculate the potential of using graphene for ultrafast wireless communications.

 

A terabit per second could be done at a range of about one meter using a graphene antenna, which would make it possible to obtain 10 high-definition movies by waving your phone past another device for one second. Akyildiz and colleagues have also calculated that at even shorter ranges, such as a few centimeters, data rates of up to 100 terabits per second are theoretically possible.

Gust MEES's insight:

Graphene is ideal because carbon “chicken wire” is only a single atom thick and therefore highly flexible. It is also held together by carbon bonds, which are among the most stable known to chemists. That means it should be relatively stable inside the human body.

Unlike silicon transistors used now, graphene-based transistors could be extremely thin, making the device much smaller, and since electrons move through graphene much faster than through silicon, the devices would enable faster computing.

In addition, silicon-based transistors are being manufactured to function as one of two types – p-type or n-type – whereas graphene could operate as both. This would make them cheaper to produce and more versatile in their applications.

New Form of Graphene Should Finally Make Graphene Electronics Possible

New Form of Graphene Should Finally Make Graphene Electronics Possible | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it

For years, scientists have struggled to build graphene-based electronics that could do the same thing as silicon superconductor chips. A new breakthrough from an international team of scientists might just change all that. These geniuses just invented a new form of graphene that's ten times more conductive.

The trick to this new form of graphene is that it allows electrons to act like photons. The impressive material is simply nanoribbons of epitaxial graphene—that's the honeycomb arrangement of carbon atoms you're used to seeing to illustrate graphene—that's manufactured using a relatively simple process.


The scientists grew the nanoribbons on silicone carbide wafers in which they had etched circuit patterns using standard microelectronics techniques. The silicone was then heated to about 1,000º Celsius, melting the silicone off and leaving these novel graphene nanoribbons with perfectly smooth edges. The graphene forms spontaneously on the etched edges of the silicon.
