There is just no real volume or appetite for buying at the moment.

My advent calendar is faulty, like last years was.

Some news into these really thin markets would really shift the share price now (Hopefully upwards) Come on Neill et al!

This isn't the specific one (looking for it) but in looking I found this one from Manchester Uni and the chief guy there Prof Robert Young.

This is a typical example of what 3 of us were finding in various science papers and it's the source of why we go on about performance dropping off a cliff over 10 layers re tensile strength to the point of being detrimental.

In this paper Manchester Uni tried the M grade from XG which is the multi-layer, the claimed average thickness by XG is 18 layers.

As you will see in this case adding the GNPS was detrimental for UTS.

'The incorporation of graphene nanoplatelets in the polypropylene matrix resulted in a drastic decrease in the elongation at break of the composites.'

'The presence of GnP into PP matrix has resulted in the improvement in the Young’s modulus but the tensile strength and elongation at break decreased with increasing filler loading.'

We have said all along multi-layer will not give the full spectrum of gains from graphene. Thermal yes, electrical yes, modulus yes, UTS no.

Hence multi-layer can be used for some gains but for the full spectrum, you need quality few layer GNPs.

It' a common theme and by looking through various papers it became obvious the issue was to do with the weak bonds between layers of the multi-layer product.

Serratia has since found other issues in the curing process with multi-layer as in his concrete examples. Perhaps this is an issue with other composites too.

I don't hold IQE, but this is of interest here too depending on who else joins the hub https://www.google.co.uk/amp/s/www.bbc.co.uk/news/amp/uk-wales-46543384

Grabster - looks like investors preferred DCTA to FGR!

I randomly pick through papers.

I’ll see if I can find a few including that one.

Typically XG C grade is smashed to bits giving poor laterals. In one it says they are so small that they shouldn’t be called platelets.

M and H grade have always been known to be multi-layer.

The spec was 5um plus on laterals on the low end so wouldn’t that mean anything below that is not covered by the patent and it’s a US patent.

Others go on about concrete quite a bit, like Talga.

I’ve not really seriously considered concrete for VRS. I have noted the few layer curing process gain though as explained by Serratia.

"Graphene@Manchester CEO James Baker suggested that commercialization of graphene was teetering at a tipping point where it could really take off."

“I think graphene is already out there in products,” added Ian Kinloch, Director of Materials at University of Manchester’s School of Materials... “I think the applications are already out there and it will only leak out gradually over time that those products are using graphene, so I think the tipping point is already here.”

I agree with James Baker. I disagree with Ian Kinloch; but I think he is only a few months premature in his assumption where it applies to real graphene.


".. One of the stumbling blocks for industry has been the abundance of different types of graphene with varying purity, crystal quality and numbers of graphene layers, which all affect what sort of applications it will be suited to. ..."
Quite; And some of those 'different types of graphene' are not graphene at all and will need relabelling.

500v - as far as I can see nobody is "ruling out any deal" regarding concrete - merely saying that one particular deal known of is something else.

[mryl] 13/12/2018 00:58

super, could you please give the reference/link for this science document if you can find it? It is exactly what I need!

[500kv] 13/12/2018 00:19

Thank you for your reply. Consequently, you are ruling out any deal between VRS and Aecom in regard to graphene in concrete? So who has an interest in 'graphene' in concrete, and should this be relevant to VRS?

Ask yourself why so many big names have appeared with VRS including DOW (check the details of the relevant news). Then wonder why the big backers of XG in the early days (Hanwah, Posco, Samsung etc) have done nothing with it after so
long.

Btw a science document the other day put 2 grades of XG platelets in the 50-60 layer range and grade C 13 layers.

[superg1] 12/12/2018 23:18

No

The Aecom bit I saw has nothing to do with concrete.

I know what it is, what it is made of, how it is made and also I believe I know who Aecom have the project with.

All of the pieces to work it out were on the web, Aecom have removed some pages since it was pointed out.

Advent hit rate now down to 6 in 8 . But the weighting of those six!Some market go all square for the year probably on Friday. Be good to have a real belter tomorrow or Friday.And to keep-going next week. We can sand out from the crowd , why not? .

To superg1
Of course the US patent was not filed by VRS - it was filed by Uni Michigan and licenced to the Dow/Dupont-supported 'graphene' manufacturer XG Sciences.
My question is rather that of how this would affect VRS supply to AECOM.
Note that I am a fervent paid-up supporter of VRS, but I still do not understand whether VRS has a sustainable commercial advantage in this field.

I reiterate my original question, "Is U.S. Patent 8,951,343 relevant to VRS?"

[lovat scout] 12/12/2018 22:37

The Apprentice isn’t about business any more - it’s Big Brother in suits as someone recently described it. Ratings rather than content driven now.

Scary isn’t it, one that has made nut milk in her kitchen and the other saying I know a swimwear brand.

Cleaning homes and offices along with kids tennis events.

So that is apparently the best the UK can do.

Wtf did he kick out in previous weeks, I dread to think.

[superg1] 12/12/2018 22:26

Besides other obvious points the date if application suggests it’s not VRS.

[alchemy] 12/12/2018 22:19

The Apprentice and any other popular business drama on TV gives everyone a false view. Alan Sugar ,,,,,,words fail me. As for Dragons Den. I'm sure our leader is two quartile above such er ... trash .

Lucky - 80%? The spread betters are improving! Used to be 90% of SBs lose 90% of money within 90 days. You are right though, the costs of trading are much higher than vanilla investment.

I've had a meeting with Claude before and he's not as scary as he's made out to be. In fact he said very little - perhaps he was more scared of me than I was of him!
