So as Oper the FCA warning

Once you spot obvious BS then you know the company is lying. So what else are they lying about.

Hence at that point I stop reading about the relevant graphene company.

As per AGM they lied in news.

super - Thanks for your comments! As you say a very difficult science. I'll be glad when the ISO accreditation transpires in order to sort the wheat from the chaff!!

"As the price goes up , there will be less of the herd as it requires a bigger outlay to make the gain"

with respect, and based on my own experience and observations over the years - so obviously just my own opinion - that's not how the herd mentality works...

Interesting find Curtain Twitcher (love your user name),What a perfect fit for Nanene that would be to enhance a critical piece of kit like a propeller.

[superg1] 28/7/2018 09:26

psx

100's are out there.

Like Haydale apparently said they tested over 200 graphenes out there and only about 5 would fit the bill of graphene.

There are a vast array of uses for nano graphite and the various types of graphene.


It's not just about production, you need an effective method of separating out the few layer content, drying it and along the way creating few defects in a microscopic platelet and having the correct aspect ratios.

EG

A typical Nanene platelet is about 4 times smaller on the lateral size than a red blood cell red blood cell and over 1000 times thinner.

In the production process you need to be able remove the larger platelets.

Now scale that to tonnes.

At an average of 5 layers and 2um lateral it's about 250 mill platelets per gram. 250 billion per kg.

They are small, it's a difficult science to master to produce few layer, with few defects and the right lateral size.

Hopefully the above gives some an idea of the microscopic nature of Nanene.

innovate Round 2 of the open grant funding is open, I should imagine that we would have put in our bid in some are.
VRS really are at the cutting edge, Fortunately most long term and some relatively new holders can see the bigger picture of where UK plc is going. VRS is an integral part of that future, not some small company making a product.
We all want those orders, but there is more to this story, I can sense it, it will come.

Thanks Scottishfield, we like to do our bit in the background now and again!

[scottishfield] 28/7/2018 09:03

For Shavian : good post over at SMT, well done.

[superg1] 28/7/2018 09:01

One of a long long list.

You need go no further than this comment

'Nanotech has invented a process to manufacture in quantity the highest quality graphene by comparison to every other'

So they have tested all the 1000's of graphene variables out there in all uses and all chemically doped forms. It would costs millions to do that.

I think not.

My rule is any BS then jog on as it always leads to more extensive BS.

[psxtalks2u] 28/7/2018 08:50

66s...certainly an interesting video in your link! Any comments super?

[66sequoia] 28/7/2018 08:41

Super, has this company been discussed here?https://www.nanotechenergy.com/our-technology

[superg1] 28/7/2018 08:15

Same paper they checked and tested some GNPs from Haydale.

The graphene nanoplatelets from Haydale, UK, were produced using a “split plasma” process.

Both types of GNPs tested shown as less than 50 nm IE less than 150 layers.

On checking the thickness was 23 and 33 nm. 70-102 layers.

The functionalised GNPs (GNP-COOH and GNP-O2 Haydale GNPs) also did not have a significant effect on the fracture performance of the epoxy.

In short multi layer graphene which is in fact graphite will not work for improved strength.

Yet so many companies still call it graphene.

Yet Hayd claim to be at the front of getting rid of the BS and list such junk with Goodfellow for sale.

So yes his eyelids do blink rapidly.

Science papers

Worth a mention as some seem to have afraid a few names as viable, EG the bears go on about XG sciences.

Once they do that you know they are way behind the curve. XG product is trash and their customers have got to know that over time.

I have said many times the key is few layer but the need to maintain aspect ratios and limit defects. That is something XG are really poor at.

So from tests at Imperial college London.

Manfacturers discription.

The XG-C GNPs, which have a platelet size of 0.3 μm, were more particulate- like than platelet and did not have any significant effects on the mechanical properties.

H grade 11-15 nm = 33-45 layers

M grade 6 nm = 18 layers

C grade 2nm =6 layers and 2um lateral

However this what they found when they measured them

'However, the thickness of the XG-H and XG-M GNPs were larger than expected, at 31.1 and 28.8 nm respectively'

So around 90 layers for both products which XG call graphene which we know is graphite.\

On the C grade they found then to be tiny platelets and as result clumped together with the clumps measuring 16 nm thick (48 layers).

"The XG-C GNPs did not have a platelet-like structure and thus the mean lateral size was approximated to be the size of each particulate agglomerate."

"The carbon content of the GNPs from XG Sciences (XG-H, XG-M and XG-C) and Graphene Supermarket (GS) were measured to be lower than the manufacturer’s quoted values"

It goes on about the platelets as being rough and damaged.

"The XG-C GNPs, which have a platelet size of 0.3 μm, were more particulate- like than platelet and did not have any significant effects on the mechanical properties."

For the XG-C GNPs, it would appear that the pull-out and void growth mech- anisms have insignificant energy contributions, compared to debonding due to the small lateral lengths of the XG-C GNPs. However, as debonding was not observed from the fracture surfaces, the fracture performance was not improved by the addition of the XG-C GNPs. Indeed the observed reduction in Gc indicates that the XG-C GNPs do not act as coherent agglomerates, but, act as defects as has been observed with some other nanoscale particles

From Preliminary Results

March 2018

Collaboration with world leading aerospace group

Applications of graphene into a propeller have been reviewed and a schedule of initial works with a total value of £0.2 million has been defined.

------------------------------------------------------------------------
16 January 2007, Dowty Propellers became part of GE Aviation Systems through GE buying Smiths Group’s aerospace division.

New facility for Dowty Propellers in Gloucestershire

Dowty Propellers, a leading manufacturer of aircraft propeller systems for both civil and military applications, intends to invest in a new facility at Gloucester Business Park, Hucclecote, Gloucestershire, UK.

The facility will be subject to planning approval and if such consent is granted, it is expected that operations will commence in late 2019.

The new facility follows Dowty Propellers announcement last year of its commitment to continue operations in the Gloucester area following a fire that destroyed its operating headquarters and blade manufacturing facility in February 2015.

Since the fire, Dowty Propellers and its employees have been operating from several interim facilities in Gloucestershire. Employees will progressively transfer to the new facility once it is operationally ready.

GE Aviation and Dowty Propellers are committed to investing in this new multi-functional facility at Gloucester Business Park and a seamless transition for both employees and customers.

The new facility will house the business headquarters and production facility, along with the main UK repair and overhaul operation.

Well , it has ended the day with a bull signal; makes me wonder if that is because an RNS is expected Monday or is it because of the large late reported buys?

Anyway, as we know an RNS can land any day Monday to Friday and not particularly fussed when one does. However, I do like the Continental/Dekabank theory although I doubt if it has any substance it is nice to have a little bit of interest from Germany in whatever guise.

Having written that it makes me wonder what their interest is, no foreign company is going to be able to take out VRS for themselves in the current circumstances and it doesn't seem as if any particularly large holding has been built up by any individual insti.

The reason for the upgrade to 3 tonnes is to be able to meet any orders for the collaborations according to the reporting in Punchline

""New production equipment is on order for scale up in the UK, we have substantially strengthened our team and I consider Versarien to be extremely well placed to produce the quantities needed for the commercialisation of these collaborations when required."

So that explains the 3 tonne move to some extent and I would guess that one of those would be Continental for a production run as I believe it doesn't require any change of machinery etc; for the production process.

The proposed collaboration with the machinery maker as mentioned by NR should be mutually beneficial financially and wonder if there will be any detail when finalised and RNS'd?

I also wonder if the Nanene has been delivered for the China 'testing' order as they won't hang about with that.

Arrow Greentech , I hope they approach the India tyre manufacturers, very innovative in India and interested to see where that goes if anywhere. Neill of course will be aware of how they are all moving along and disappointed that he is busier than before all of the appointments... not really ;)

Blood moon far more interesting- except for the clouds!

[realcooltrader] 27/7/2018 20:38

Ta ls, I think I understand!

[lovat scout] 27/7/2018 20:20

Rct- the closing price for a share is firstly the auction price (Uncrossing Trade) or if there isn’t an auction, the mid price of the buy/sell quote for shares with market makers. If there is no closing auction for shares with no market makers VOD etc ( which is rare) then it’s the last trade.

[axotyl] 27/7/2018 19:03

DimTim has retreated to his own Twitter lair, and appears to have given up hassling NR, and lick his wounds. Not easy to sympathise when he comes out with beyond-ignorant gems like this (earlier today):

'....I've also seen nothing to justify the claim that #nanene is any better than other similar products which current sell in vast quantities in comparison..."

Where does he do his research? The Beano?

At least he had the sense not to post it on NR's Twitter feed.

[lovat scout] 27/7/2018 19:02

Fest - I’m nothing like Jacob Rees Mogg!

[realcooltrader] 27/7/2018 18:34

So, the UT is at 125.5p, does that mean we should open slightly up on Monday? I never really understand UTs.

[festario] 27/7/2018 18:28

I like Lovat Scout's posts.... and I nod in agreement at them, as if I have the faintest clue what they mean.
