Morning, played San Roque Sunday, my last day of 4 today, drive back up near Alicante this afternoon :-( ....Great idea, next time, yes plz ...

[freddievas] 10/10/2018 07:17

Squire, that’s my part of the world! Fancy a round at San Roque? Weather permitting of course.

And also this quote from grabsters article :

"The newest paper, on which Novoselov is a co-author, focuses only on the “liquid phase exfoliation,” the slicing graphite method."

This method explained below and not relevant to vrs to my laymans knowledge. Aimo. Dyor. Best ellis




EDIT : just checked excellent mike bremner research in header, part one. This quote :

"Mechanical exfoliation of graphene - Mechanical exfoliation is the original method used by Prof Sir Andre Geim and Prof Sir Kostya Novoselov to isolate a single graphene flake. Scotch tape was used to remove layers from bulk graphite, these layers are then transferred to a substrate such as silicon. On removing the tape single layer graphene with large crystal sizes is left on the substrate.

My Opinion: exfoliation produces graphene with the lowest number of defects and highest electron mobility - 3M would be keen if we used Scotch Tap still, however this is the process that the University of Manchester focussed on with their 2D-Tech Graphene production company in partnership with the University of Ulster who patented the process to create high quality few layers of Graphene – this process is also sometimes called grinding."

So the method used by vrs to produce +nanene wasn't included in the 'fake graphene' report, and so +nanene not tested by them. This article has proved useful in highlighting the need for industry standards, and also shows why many companies producing non iso compliant graphene/graphite are resisting their introduction. Aimo.

Not yet ??!!

Here is research paper of cambridge graphene detailing their method to produce graphinks. Single layer and few layer graphene produced. Graphinks data sheet on 2dtech website is for few layer graphene. And a secondary lesser grade graphink too. But at least companies know what they are buying and investors in vrs know the quality of the products being produced ! Aimo. Best ellis

"Graphene is a promising alternative conductive filler.(36) Graphite can be exfoliated viasonication using solvents(37-42) ;or water/surfactant solutions.(40, 43) Dispersions of single layer graphene (SLG) flakes can be produced at concentrations ∼0.01g/L(37)&nbsp;with a yield by weight Yw ∼ 1%,(37) where&nbsp;Yw is defined as the ratio between the weight of dispersed material and that of the starting graphite flakes.(44) Dispersions of few layer graphene (FLG) flakes (<4 nm) can be achieved with C &sim; 0.1 g/L(45) in ;N-methyl-2-pyrrolidone (NMP) and ∼0.2 g/L in water.(40)"

From that article grabs;

“Kauling and colleagues’ article is, therefore, a much-needed wake-up call for graphene producers, buyers and researchers to agree on and to adhere to sound standards: a transparent graphene market would benefit everyone, except perhaps unscrupulous vendors,” he writes."

Hurry up UK GOV; get uk graphene testing service up and running asap while we have world lead ! It was announced in august, surely it will be in place before GEIC opens in december ? :-0 aimo. Best ellis

So who will be going to the Total Market Solutions Event in London on Thursday? I’ll be there and would love to meet fellow members of the Versarien family.

[redchef] 10/10/2018 01:43

These articlesare probably also the cause of the selling we saw yesterday. PIs who haven't done their research panicking in case all graphene producers are as bad as each other

[grabster] 10/10/2018 00:35

“Our extensive studies of graphene production worldwide indicate that there is almost no high-quality graphene, as defined by the [International Organization for Standardization] in the market yet,”


Just reminding Tim Kempster (aka loglorry) who keeps banging on about how many graphene producers are outselling Versarien - and who keeps insisting that superg1 is wrong to describe so many competitor products as rubbish; many of them apparently ARE rubbish.



(Article based on yesterday's Fake Graphene report in Nature magazine)


The report goes a long way to explaining why big-name companies and Chinese provinces are so keen to talk to Versarien if Versarien is one of so very few (maybe the only one?) producing best grade graphene.


It also means that - contrary to what Tim Kempster (loglorry) argues - we are not just basing our confidence on whatever we hear from Neill Ricketts and superg1. Versarien really is something special. That became evident last year when Versarien did so well in the CPI tender, setting the company apart from others:

La Reserva tomoz, Sorogrande etc ...

[chillpill] 10/10/2018 00:09

There are some warped individuals around....especially on ADVFN!

[freddievas] 09/10/2018 23:59

Where in Spain are you playing Squire?

[diversification] 09/10/2018 23:48

And so it begins, the adoption of graphene into products such as cement in America. Ford adopting graphene to reduce noise from the engine.

The race to a competitive advantage begins, others will follow suit and fast.

Who’s graphene provides the best results will determine market share, watch this space.

Last man or woman please turn the lights off. Sleep soundly while the shorters sweat... :-)

[serratia] 09/10/2018 23:34

O/T,
As it's very late one for squire/sg. On a phone in Lee Trevino was asked how do you get the ball to come back to you when you hit the green ? He said how far do you hit an 8 iron ? Ans 120 yds. Reply then why do you want it to come back to you ?

[1crackupboom] 09/10/2018 23:21

Just sussed it. Rainbow is that nutter from last November who used to put loads of posts about failed iof ramper. This is nothing to do with vrs but a vendetta against superg.

[thetrophyman] 09/10/2018 23:08

Reading this board is like drinking 16 cups of 3 heaped coffee in one day! happy to have averaged down today though, didn't think I'd get a chance after my first buy at 164

[haz101] 09/10/2018 22:56

Not ot at all Hew well spotted

[rainbow23] 09/10/2018 22:50

NR still stringing his followers along with rampistic tweets I see.

I remember, a few years ago, the chief ramper Superg ramping Iofina to the high heavens as it plunged into oblivion. Looks like he's trying to repeat the trick here. Beware,he comes with a wealth warning.

[haz101] 09/10/2018 22:37

Agree with several posts this evening regarding shorters, I have started to filter as I go along, do not engage, ignore! no time for these kinds of people whatsoever, im getting cross just thinking about it :(

[squire007] 09/10/2018 22:33

Hew, very well spotted, I have all NR tweets today and there are hints of a RNS tomoz/soon! Just my sceptical self feels if it was due at 7am we would have seen an uplift late on! My money is on Thurs, with an outside chance of midday tomoz...Now get that stockmarket open :-)

[1stokie] 09/10/2018 22:31

The usual suspects on this board should be prosecuted.They are so transparent and so desperate .Its a tough job massaging your short.
