Nice to see this thread back to its best with some excellent informative posts today, thanks all :)

Bloomberg article shows EU planning to match china and US in world passenger car production. Looks like the penny has dropped. Policy being used to push EV's via quotas. Aimo. Best ellis

Lovely colour in the presentation slides too 😁

With plastics and global warming being high profile at present I'm sure that graphene will make a contribution in reducing both in the future.

Higher than usual volatility of October? Dow in green now.

Also good to read Chris Ciovacco on such days.

cdub1, good find, thanks for sharing!

Lovely presentation esp the market demand and scale up slides ... time to sit on hands and wait for things to play out

[rogerbridge] 08/10/2018 21:28

Cheers Ellis.

Yes that’s from the Chemspec Europe show earlier in the year. Was kept rather hush hush, just happened to stumble over it this evening. Does make you wonder the potential of this company! If we have cracked the Graphene scale up problem why the heck we aren’t worth A LOT more. Heck pot companies in America have had markets of $25 billion+ recently and any idiot can grow weed but try making few layer “real” Graphene!

The Ricketteer says we are in a very strong position and I believe him. Glad I used my hooker money for more VRS shares today.

[ashehzi] 08/10/2018 20:53

Thanks for above link. Quite a good one. Worth going through for everyone invested here (not trading 😊)

For reinforcement of your belief in vrs after markets turmoil, see above post of ppt from Dr Stephen Hodge.

A good VRS presentation I found whilst surfing the net this eve with pictures of our product: [url]hxxps://www.chemspeceurope.com/2019/assets/2._Versarien_Graphene_scale_up_Hodge.pdf[/url]

P.S thanks mryl

So I have gone through the data in the article "the Worldwide Graphene Flake Production" and I am going to share the highlights for those who can't access the content or are too lazy... I mean busy :)

First, the authors have characterized "graphene" flakes from 60 UNNAMED producers worldwide, so we do not know whether Versarien's Nanene or GNP-HP are amongst these...

What we do know is the following:

-Out of 36 companies, no company is currently producing above 50% graphene content... only one company produces 40-50% graphene flakes, and 2 companies produce 30-40% graphene. The majority of the companies are producing less than 10% graphene content, so they are essentially 90% graphite.

- Most companies do not control at all the distribution of the number of layers of their flakes, all samples actually contain some graphene, but it is often lost in a sea of graphite. So some companies claim to be making graphene when their product is actually 1% graphene...

- only 17 products have a carbon content of 90-100%, all the other samples had less than 90% carbon. They do not differentiate within the 90-100% range, although 99% carbon is probably way better than 92%...
Similarly, only 7 samples had more than 50% sp2 bonds (crystalline graphene should have 100% sp2 bonds).
So most products are heavily contaminated.

-Then the lateral size... only one company with an average lateral size of 11-100 microns, 1 company in the 5.1-7 microns range, and 2 companies in the 3.1-5 microns range. 85% of companies produce a lateral size under 2 microns, which is essentially useless for mechanical properties according to many previous posts although I have not checked that myself.

They do highlight the fact that they haven't tested all the products out there and they may have missed some high-quality graphene platelets on the market.

Also, I find it really annoying that they haven't linked the various properties that they have measured, what I mean is they do not explain whether the sample with a lateral size of 11+ microns is one of those with a high graphite content, or whether it has a high or low carbon content... They could have been a lot more transparent in the way they presented the data! and they could have named the producers as well.

Bottom line is most of the graphene companies out there produce either fake graphene which is essentially graphite and/or flakes with a tiny lateral size and/or heavily contaminated flakes.


Now what we know about Nanene, according to its data sheet:
- 60% under 5 layers
- 90% under 10 layers
- 98% carbon purity
- lateral size under 10 microns

So according to this data, Nanene was not one of the products tested in this paper and is superior to all the graphene platelets that were tested.
But could it be that it is one of them? in which case probably one of the 3 samples only that contained 90% flakes under 20 layers (the issue I have with data transparency in the article shines here, under 20 layers could be 11 or could be 19, huge difference!!). But if it is one of them then there is still room for improvement, especially regarding the graphite to graphene yield and the sp2 hybridisation (related to contamination and defects).

Westcott space cluster link roger :). Best ellis

Great danes ! Policy makers upping the ante here. Good news for 2D ev solutions hopefully. Aimo. Best ellis

Amazing what venture capitalists will fund ! Best ellis

And Total Carbide have joined the Westcott Space Cluster.

A nice October Versarien update in my inbox. Nearly missed it as it was from Samuel Nivison.
Good to see Stephen Hodge and Neill, Both speaking at separate events in the USA later this month.

[squire007] 08/10/2018 19:53

Shares bad golf good !!!! Dunno what to make of the day .. :-) :-( ??Anyway added 20k midday ...one last top up and i then have to give in!Blame IOF ... lol

[ellissj] 08/10/2018 19:48

Thx serratia. Could all the samples be graphene/graphite oxide ? Rather than gnp's ? Just thinking if tested in asia. Atb. Ellis

[serratia] 08/10/2018 19:41

The original paper was from the University of Singapore with a contribution by Novoselov the Manchester Nobel guy.
Of the samples tested 6 contained over 20% Graphene, 21 had less than 10% Graphene. The 'other' material will be materials used in the production process. 36 samples had 9 layers or less. 8 averaged 5 layers, 11 averaged 4 layers and 7 averaged 3 layers.
We know layer number is only part of the requirement so on to laterals. From memory 2um laterals don't provide strength in composites. Too long a lateral also doesn't work. I've still to pin down how long is too long.
32 samples had laterals under 2.5 um., one had 11 to 100 um. 2 were at 3 to 5 um and 1 at 5-7 um
Nanene is sub 10 um so there's a fair chance that it's the 5 to 7 um sample.

I have said since the start of the year that it would be a bonus if we get the first commercial deal this side of the New Year. It is 2019 and 2020 when you can really expect things to kick in.

Having said that they do seem very confident in how things are progressing.

[sonsonnyjim] 08/10/2018 19:11

All positive noises, still wondering what superg was hinting at as very near term

[festario] 08/10/2018 19:07

Confusing innit?
