The source article for the concrete claims made earlier is here

Interesting that they produced their own GNP which they describe as FG and also bought some commercial product which they label IG (no name of product given). Their own stuff seemed to produce the same results.

Oh dear. I can't read them but it looks like the desperate posts are multiplying.

@HK the only guarantee VRS can give is that the platelet lateral size is between 0.1 and 10um. They have deleted the average platelet size during a "typo" incident at some point in the past although we don't know when. We have no idea where it sits in that range anymore.

XGS are one of the few GnP companies actually selling their product with CONFIRMED sales from Ford Motor Company. They are valued at around £25m based on their last fund raise which was successfully completed recently I believe.


Oh and you wrote
"Nanene sits in the range of 1um to 10um in terms of particle size."

I think you mean 0.1um to 10um if you are referring to lateral size? Probably another "typo".




------------------------

Spid,

You are aware that XG Science's Grade C particles are aggregates, right?

In fact, the only guarantee they can give is that their particle size is 100% <75um - nearly 38 times the average platelet size of 2um that they quote.

Nanene sits in the range of 1um to 10um in terms of particle size.

Hoverflyman, regarding the strength within the 2D graphene plane, and the weakness between the planes, it's probably easier to visualise than to describe.

Have a look at a C6 ring of carbon:

The image on the right shows carbon atoms covalently bonded in a ring, the building blocks of graphene. The covalent bonds between the carbon atoms are incredibly strong and this gives graphene its strength.

The p-orbitals (the balloons sticking up and down from each carbon atom in the ring) allow for pi-bonding between molecules, but this is very weak. This is how pencils work, the layers of graphene slide over one another and are deposited on the paper/surface.

Too many layers of graphene, and you'll get "sliding" within the composite, which is great if you want modulus/elasticity/sliding, but not so great if you want improved strength.

These vertical bonds (pi bonds) need to be "exhausted", i.e. mopped up or absorbed by components other than graphene to prevent this sliding.

I think this is partly what Haydale's business model was based on, the fact that graphene would need a degree of "functionalisation" to make it dissolve better into composite materials, by helping to "exhaust" some of the non-carbon-carbon covalent bonding.

I hope this helps?

My mistake HK, I thought the XG Science C 2um was an average like the other products,

BTW C grade is graphene,

well worth reading the following research paper that tests XG product range in the same application,

Good post @spid although you refer to V1.3 may have completely different numbers once the typos are fixed :-)

You might want to check your figures SugerG1, it appears to only be 73% that is under 10 layers or is this another typo ?

"Some seem to forget what is leftover from the Nanene process it's called HP and does have a value.
That's 91% less than 10 layers or less. Nanene is 90% under 10 layers.
HP under 5 layers 18% Nanene under 5 layers 60%."

Hi Ratpat,

There is nothing wrong with correcting information that is incorrect, NR learnt that his TDS had a typo. I thought his personal attack on Loglorry was uncalled for, He could have said thank you for pointing out this mistake, we will promptly correct it.

Good thing Superg1 has the edit button to correct his post that has the incorrect information, Maybe he was going off memory rather than reading the TDS.

Does anyone know what the capacity is of GNP - HP ?
is the future 3tpa capacity based on both Nanene and GNP-HP ?

I wonder if Dim recuperated the losses he has lost this year? Probably not!

"XG Science's Grade C ( the closest product to nanene)is few layer graphene, with a average platelet of 2um, can be ordered with surface areas of 300, 500 & 750 m2/g

Why does Nanene few layer graphene only have a surface area of 45m2 /g Vs XG sciences 300-750m2 ?"

Nanene sits in the range of 0.1um (edited) to 10um in terms of particle size.

Loglorry1. I may have missed it but have you answered the question "Why are you here"

[ratpat999] 24/10/2018 12:53

Spidi spouting nonsense !! go away lick your wounds and grow up, pathetic attempt to deramp idiot 🤐

[mj10] 24/10/2018 12:51

loglorry was correct in his assumption that the share price would rise today that nobody seems to have commented on
this leads me to think he has already closed his position

Spid, I think Super answered your question before you asked!Several posts before you posted that the first time he had posted regarding surface area.

How do you the bulls explain the deletion of a whole row describing the average platelet size of Nanene as a "Typo"?

[superg1] 24/10/2018 12:33

Some seem to forget what is leftover from the Nanene process it's called HP and does have a value.

That's 91% l 10 layers or less. Nanene is 90% under 10 layers.

HP under 5 layers 18% Nanene under 5 layers 60%.

Nanene lateral <10um, HP <27.5um.

HP doesn't see as much gains as Nanene, the key factor being the fewer layer and more desirable lateral sizes

So once you go over 10 layers as stated many times, performance for all the gains from graphene falls off a cliff.

Graphene also strengthens aluminium -

In recent years, graphene has attracted considerable research interest in all fields of science due to its unique properties. Its excellent mechanical properties lead it to be used in nano-composites for strength enhancement. This paper reports an Aluminum–Graphene Nanoplatelets (Al/GNPs) composite using a semi-powder method followed by hot extrusion. The effect of GNP nano-particle integration on tensile, compressive and hardness response of Al is investigated in this paper. It is demonstrated that 0.3 wt% Graphene Nanoplatelets distributed homogeneously in the matrix aluminum act as an effective reinforcing filler to prevent deformation. Compared to monolithic aluminum (in tension), Al–0.3 wt% GNPs composite exhibited higher 0.2% yield strength (+14.7%), ultimate tensile strength (+11.1%) and lower failure strain (−40.6%). Surprisingly, compared to monolithic Al (in compression), Al–0.3 wt% GNPs composite exhibited same 0.2% compressive yield strength and lower ultimate compression strength (−7.8%), and lower failure strain (−20.2%). The Al–0.3 wt% GNPs composite exhibited higher Vickers hardness compared to monolithic aluminum (+11.8%). Scanning electron microscopy (SEM), Energy-Dispersive X-ray Spectroscopy (EDS) and X-ray diffraction (XRD) were used to investigate the surface morphology, elemental percentage composition, and phase analysis, respectively.

Hi Superg1, I posted this earlier, I am still yet to see your reply.

Can you please explain the following as I find it really hard to understand why you think FGR are BS their investors,

Single layer graphene having a surface area of 2630m2 / g

FGR's Multi Layered Graphene, Has a surface area of 500m2 / g (you consider this graphite)

XG science's Grade H is 15nm in thickness (44 layers)has a surface area of 50-80m2/g - this is very similar to the nanene surface area.

XG Science's Grade M is 6-8nm in thickness (17-23 Layers)has a surface area of 120-150m2 /g

XG Science's Grade C ( the closest product to nanene)is few layer graphene, with a average platelet of 2um, can be ordered with surface areas of 300, 500 & 750 m2/g

Why does Nanene few layer graphene only have a surface area of 45m2 /g Vs XG sciences 300-750m2 ?

Is the 45m2/g another error, or is the error the description - Few Layer Graphene ?


It seems odd to me that all of these other companies you claim produce graphite have a much larger surface area vs nanene.

VRS - up 18.5p. The rise was bound to come. VRS is massively oversold. I see £1.50 end of week with possibly £2.00 within 2 weeks. Nothing had changed apart from the doomsters frightening PI's. If bad news was coming, NR would have been compelled to tell us. In fact, he told us that all is well on Twitter. Good news and we'll see £2 immediately. I've made a fair bit on my recent purchases.
