Dear @AndrewRodgers-g7c, ISO has a well crafted standard definition of what graphene is, and what it is not which is what we follow to make that determination. Some forms of graphene are turbostratic which is what you may be referring to, but these are still graphene according to the ISO standard. The Graphene Council offers testing and characterization services produced in the form of a Technical Data Sheet for anyone that wants to know for certain if their material is actually graphene or some other form of carbon.

@@TheGrapheneCouncil The ISO website says that graphene is "a two-dimensional material up to 10 layers thick FOR ELECTRICAL MEASUREMENTS". By any other definition, including IUPAC's, graphene is a SINGLE LAYER. The editors of the journal Carbon published a paper in 2013 entitled “All in the graphene family - A recommended nomenclature for two-dimensional carbon materials”. In this paper a set of basic principles is set out, the most important of which is the recommendation that the term “graphene” should be STRICTLY RESERVED FOR THE ISOLATED MONOLAYER. Structures with more than one layer should be specifically labelled as “bilayer graphene”, “trilayer graphene”, “multilayer graphene”. To call the junk that James Tour is making "graphene" is deeply misleading.

We do not discuss pricing in public forums, prices vary by producer and are very volume dependent. We do have a market report at www.thegraphenecouncil.org which has this kind of information.

Totally agreed, that religious nonsense makes me irritated. Drop it and get to the facts and the pure science, which is (thankfully) what this video is about.

His science is also BS

Many thanks for the feedback. We have looked at EPA as partners from the beginning and work with them to help graphene companies meet their compliance obligations.

Hi Kim, thanks for your question. AGM was acquired by Universal Matter and integrated, in particular the application development team in the UK. We expect, as in any new industry, to see continued consolidation from the current set of more than 300 commercial graphene producers.

Dear @quantumenergysolutions9128, We cannot discuss specific company pricing in a public forum. There are vast ranges in pricing for graphene based on the specific form of graphene (number of carbon layers, lateral flake size, whether it is functionalized, Graphene Oxide, etc. as well as the volumes purchased). For complete market data we encourage interested parties to check out The Graphene Report: www.thegraphenecouncil.org/page/TGR

It is always complicated to scale up lab scale innovation. They have a track record of bringing products to market, so I think it could work and if it does it will be a major disruptor for the likes of the automotive sector in Norway. Much lower cost of materials to produce than Lithium batteries, but it will attract a lower weight tax than sodium batteries.

Using graphene to reduce embedded CO2 and improve the physical characteristics requires only a very, very small amount of graphene. At those low levels, it is not sufficient to generate a current sufficient to detect changes. That does not mean graphene could not be engineered into a sensing role within a structure but it is unlikely that it is near term possible to make an entire structure capable of sensing.

@pranavvaidya3634 I am not entirely clear about your question but I would say that using Raman to evaluate a graphene sample is the minimum test needed which gives you some basic but incomplete information. Raman y itself is less expensive than other tests but it is also not sufficient on its own to characterize a graphene sample. As in other cases, we encourage you to contact us about what you are trying to achieve and we can give you better guidance. tbarkan@thegraphenecouncil.org

Thank you for your question. Testing costs will vary of course depending if you are testing a graphene sample or if you are testing a product that claims to contain graphene. In the case of testing graphene material directly, we can conduct a complete analysis that complies with the Graphene Classification Framework and results in a Technical Data Sheet that can be used by the company that produced the graphene, or we can conduct more limited testing. The best approach is simply contact us to discuss what type of material you have, what you want to test and what the intended application might be. We can then provide a quote for the testing services. Send me a note: tbarkan@thegraphenecouncil.org.

@@TheGrapheneCouncil Thank you very much for your quick reply, it is greatly appreciated. I will contact you by email very soon. Again, thank you for taking the time to respond. Have a great day.

I don't want an expensive analysis at this moment in time. I just want someone to confirm if I have graphene (one to several layers) from my optical microscope samples, but it seems impossible.

@@rogerwilson6367 I'm afraid it is, the graphene gate keepers were already established.

Glad you enjoyed it!

Dear @crobinso2010, It is stated in the webinar and in the Q&A that Gerdau does not make their own graphene ut instead that they source different forms of graphene from different products according to the end use application and the attributes they are trying to drive. Which suppliers they use may be business confidential so you would have to contact Gerdau directly though they likely might not disclose who they purchase from for confidentiality reasons.

Dear Ryan, All of the materials we tested are defined as graphene under ISO Standards. The 19 forms and types of graphene included graphene nano-platelets, graphene oxide, reduced graphene oxide and functionalized graphene materials. We do not name the producers or products because our objectives was to conduct an unbiased, head to head, non-optimized test to simply determine if graphene can significantly improve composites. The net results is that even though the tests were not optimized at all for the materials tested, we saw significant improvements which can be made even better when optimizing specific graphene materials with the target application. Anyone that would like to connect with qualified graphene producers and those that provide functionalized graphene for the composites sector can contact The Graphene Council at tbarkan@thegraphenecouncil.org or visit www.thegraphenecouncil.org to request more information. Thank you for your interest.

I appreciate the details and patient diligence in your response.

Hi Ed, graphene is being used in devices and sensors, primarily for diagnostics.

Tell me does it matter that they are moving product already that has your attention more or the partnerships?

@@lifeisgood339 The main draw for me was the batteries. But the other segments are very exciting. Note: In the lubricant, only a fraction of 1% is graphene. And I'm *guessing* that graphene for lubricants & coatings is probably easier to make than battery graphene, so I suspect that there will be more competition there. But all in all, getting $6 million in non-dilutive funding for the battery from Rio Tinto is a nice sign. So, it's all of that. Getting some revenue while the battery is advanced is a very good thing.

Dear "Beaver Buoy", real examples of graphene use in actual products and applications abound, from the graphene companies making batteries and battery materials using graphene (Lyten, Talga, Nanotech Energy, Ceylon Graphene Technology . . .) to the auto companies using graphene enhanced components (Ford Motor, Briggs Automotive, Renault, . . . ) to performance textiles (Kyorene, Safety Gloves, performance sportswear, Versarien, Graphene-X) to use in concrete and cement (Nationwide Engineering) to next generation sensors (Bio, Hall effect, Pressure, etc. from companies like Paragraf and Graphenea). And these are the examples that are not under NDA or are trade secrets and therefore not public.

seems like a scam@@TheGrapheneCouncil

I haven't seen real applications in the industries, these are all concepts@@TheGrapheneCouncil
