For years, graphene has been hailed as the new wonder ___ because of its extreme bendability, transparency as well as electrical and thermal conductivity.

With these outstanding properties, graphene may one day enable firms to produce bendable displays and supercapacitors as well as flash memory storing enormous amounts of ___ .

___ all over the world have therefore been working on graphene, but the most influential ones are the Russian-born scientists Andre Geim and Konstantin Novoselov.

In 2001, Geim and Novoselov started their ___ on graphene at the University of Manchester and gained ___ in this field.

They made ___ regarding its production and finally composed the first layers of graphene in 2004 via mechanical exfoliation with sticky tape.

When they reported about their graphene production in several scientific journals, they stirred ___ with ___ worldwide.

However, mechanical exfoliation is rather impractical for large-scale graphene production. Therefore, ___ been initiated to develop more feasible methods.

Scientists usually share their ___ in scientific journals. However, there ___ that they will soon experience a breakthrough in this respect.

Most newly developed graphene production methods are still too expensive or produce graphene layers which contain too ___ in the honeycomb lattice.

Nevertheless, most researchers see chemical vapor deposition as the most promising method and provide ___ in diverse publications how to best utilize it for the production of graphene layers.

___ will show which method will be the most efficient one for industrial graphene production.

You can find ___ about graphene and its current production methods on the internet.

A few years ago, for example, the Mechanical Engineering journal published the article "Graphene: The Not-So Wonder Material?" in which pros and cons of diverse production methods are discussed. ___ especially interesting, as they also consider environmental issues.
