This section of the website is here to help people identify good (and bad) Graphene suppliers and production techniques. We want to provide potential purchasers of Graphene with enough unbiased information about what's out there to encourage educated and swift purchasing decisions. It's common sense that you need suppliers you can trust and we could all do without the expensive trial and error process that can sometimes be involved.
In this thread, I've scrutinized the content of a rather suspicious article entitled: 'Polish discovery – large scale production of graphene made possible'. (I'm not responsible for the poor grammar contained in the article)
I found the content of this article talking about a 'Polish discovery' to be highly dubious and factually incorrect in a variety of places. The writer of the article appears to be oblivious to the many amazing developments coming from the rest of the World. The article makes out that the USA are the only other country aside from Poland worth mentioning.
What they've written about how Polish scientists have overcome the shortcomings of Geim and Novoselov in such context is borderline libelous and almost certainly insulting. It creates the impression that Polish scientists have 'saved the day' which just simply isn't true. It was suggested to me earlier today that the production process they are referring to involves too much oxidization and by no means is 'Graphene of the highest quality' - However it doesn't really say anything tangible about how and why their production process is so good, other than 'it's going to be ready next year'. If you agree or disagree please comment on this thread.
We're just as intrigued as we are confused about the motivations of the author of this article - Quote: 'Poles are ahead of other groups of scientists around the world who work on methods of industrial production of graphene'. We'd also like to add that the owners of this site have many Polish friends and share the stereotypical view that Polish people are generally very hard working, friendly and honest people. However, allegedly this article contains some proper whoppers!

Polish discovery – large scale production of graphene made possible
December 18 2013 at 9:39 PM
The discovery can help to revolutionize computer market in the future. Poles are ahead of other groups of scientists around the world who work on methods of industrial production of graphene.
Graphene is an extraordinary material. It consists of a single layer of carbon atoms. It is several hundred times stronger than steel but bends. Conducts the current hundred times better than copper and much better than silicon, which is still a base of all systems used in electronics, including computers.
For the discovery of graphenes properties, scientists Andre Geim and Novoselov Konstantin got a Nobel Prize in physics last year. However, graphene they had made was in a form of tiny flakes with an area of tens of microns. This is not enough and the material was not suitable for commercial exploitation.
Polish scientists from Institute of Electronic Materials Technology, and from Department of Physics, University of Warsaw have overcamed this barrier and managed to devise a way to transfer the production of graphene from the laboratory to the factory scale. They used standard equipment being used for years for the manufacture of semiconductor structures. Success is reported in one of recent issues of NanoLetters journal.
- Our method allows to produce large areas of graphene of highest quality. It will be possible to fit more electronics on a small area explains Prof. Jacek Baranowski As a result, computers will be smaller, more fuel-efficient, and several hundred times faster.
According to professor new material is in advance of silicon, which electronic era is inevitably coming to an end. In ten years miniaturization of silicon based systems will achieve an end and graphene will replace them he says.
It is true that Americans have already found a way. But their proposal, based on the use of silicon carbide requires heating to extreme temperatures over 1500 °C. This is a significant drawback from economical point of view.
Poles now work on graphene-based transistor, which should be ready next year. These devices will operate at frequencies of hundreds of terahertz, values inaccessible for silicon.
