Thanks for sharing ... sums up current situation without standards nicely!

[mryl] 08/10/2018 19:00

Standard methods that can be found in research laboratories around the world:
- Atomic force microscopy (AFM) measures the thickness of graphene stacks.
- Optical microscopy provides us with the flake size.
- Raman spectroscopy provides information on the structural integrity of the sample as well as indicates the presence of GO and/or rGO.
- X-ray photoelectron spectroscopy (XPS) measures the carbon content (purity).
- Scanning electron microscopy, and transmission electron microscopy providing the Supporting Information on the sample morphology.

What he said is we are in a strong position. Doesn't mean China will accept it

This is why

@GrapheneCouncil
@NPL
and
@isostandards
are so important, I'm cool and relaxed, everything comes to those that wait.

It depends on how you measure 'close'. I cannot be specific publicly, but if close means signing a deal, then we could honestly sign something tomorrow, no problem at all; but it wouldn't be right unless everything was perfect for the future of the company and our fab investors.

Progressing royally on a number of things China and non-China related and on aspects that go 100 miles beyond the present.... which is my whole point - timing is an important concern, yes, but 'present time' is being balanced against 'aspiration'.

They are too modest but as Ceo and largest shareholder I am amazed at their progress, @PeterJVRS has only just come back from negotiating face to face in China. We are in a very strong position now.

[wuzy] 08/10/2018 18:42

Evening all, topped up twice this morning but hay ho still getting as many as l can afford, pray what is the post or article everyone is talking about. Ps, nice to put a face to you superg, but they really need to put out some contract news or this is just going to keep on going south have a good evening all.

[1crackupboom] 08/10/2018 18:41

The Chinese are obviously playing for overly good terms and VRS sticking to their guns. This means the contracts are written and ready to sign. We have 30 different partners that can sign. One of them will and then they all will. Then we sit back eating chips AND rice.

Of course, in the supplementary report pdf re 'fake graphene' article, the use of Raman Spectroscopy by the authors cites previous research undertaken under reference number (8) "Raman Spectrum of Graphene and Graphene Layers" A. C. Ferrari, J. C. Meyer, V. Scardaci, C. Casiraghi, M. Lazzeri, F. Mauri, S. Piscanec, D. Jiang, K. S. Novoselov, S. Roth, and A. K. GeimPhys. Rev. Lett. 97, 187401 – Published 30 October 2006



Which as you will note refers to research done by our prof ferrari (now cambridge graphene) et al in the use of raman spectroscopy to characterise graphene.

This refers to the conclusion prof ferrari et al made :-

"In conclusion, graphene’s electronic structure is
uniquely captured in its Raman spectrum, that clearly
evolves with the number of layers. Raman fingerprints
for single-, bilayer, and few-layer graphene reflect changes
in the electronic structure and electron-phonon interactions
and allow unambiguous, high-throughput, nondestructive
identification of graphene layers."

And here is the link to prof ferraris research: click on 'view at acudemia.com' to link to the pdf:




So as a layman, it seems identifying upto few layers of graphene using raman spectroscopy is acceptable practice. Aimo. Dyor. Best ellis

Twitter link, sorry if already posted but fascinating:

[sonsonnyjim] 08/10/2018 18:37

Did I just get a compliment, where's my diary?

[richardc77] 08/10/2018 18:33

Well the comment from Neill on Twitter sounds pretty conclusive to me. It WILL happen just when not IF. I’ll be topping up.

[anotherdrink] 08/10/2018 18:32

Good tweet sonnyjim. Looks like we are edging closer to a deal in China:)

[sonsonnyjim] 08/10/2018 18:28

They say they COULD do a deal now, but not on the terms they want. This means a deal won't be done UNTIL those terms are agreed. This is different to saying a deal WILL be done. Understand? If you said a deal looks likely then I agree

[1crackupboom] 08/10/2018 18:26

They have. They said they could have signed a deal already. They are being picky. Have you gone short?

[sonsonnyjim] 08/10/2018 18:24

Crackup, no they haven't please don't ramp

[1crackupboom] 08/10/2018 18:22

Neill and co have confirmed that a deal will be done on Twitter. They are just waiting to get all the terms to their satisfaction.

That's not an answer to the question Hatty

[hattie1] 08/10/2018 17:49

Sonny if youve got a question personal to our CEO why not ask him or are you yet again less than subtley deramping ..

[ridicule] 08/10/2018 17:49

Amen to that ChimpAndy1! I have not topped up, but I have not sold any either!

[scottishfield] 08/10/2018 17:44

Any (additional) sells turned up yet? Must be some, as more buys than sells shown.

[haz101] 08/10/2018 17:43

Chimp currently on 22k (paused for breath at 20k) my capital outlay would of bought over 200k if I’d of purchased at IPO, as u prob know being a fellow LTH ive only been in the game since July so am very happy to have accumulated as much as I have at the prices since then, sort of puts it in perspective though,
best regards Haz
