Scalable 100% yield production of conductive graphene inks
(Nanowerk News) Conductive inks are useful for a range of applications, including printed and flexible electronics such as radio frequency identification (RFID) antennas, transistors or photovoltaic cells. The advent of the internet of things is predicted to lead to new connectivity within everyday objects, including in food packaging. Thus, there is a clear need for cheap and efficient production of electronic devices, using stable, conductive and non-toxic components. These inks can also be used to create novel composites, coatings and energy storage devices.
A new method for producing high quality conductive graphene inks with high concentrations has been developed by researchers in the GRAPHENE FLAGSHIP, working at the CAMBRIDGE GRAPHENE CENTRE at the UNIVERSITY of CAMBRIDGE, UK. The novel method uses ultrahigh shear forces in a microfluidisation process to exfoliate graphene flakes from graphite. The process converts 100% of the starting graphite material into usable flakes for conductive inks, avoiding the need for centrifugation and reducing the time taken to produce a usable ink.

hi sandbag...good to see you and others here

[1madmarky] 22/2/2017 06:13

Good to hear from you skylite. Fingers crossed for the price of iodine.

[spike_1] 22/2/2017 06:09

Lucky - your recent post on ThinPly and F1 certainly adds importance credence to the 'notion' that one of the F1 teams is planning on using VRS's GNP's.

Exciting times!

Best wishes - Mike

[spike_1] 22/2/2017 06:00

Off topic: Hi skylite - good that you are still alive and hopefully well. I see from your recent posts that you've not been around much since IOF ;0(

Yes I'm also waiting for the iodine price to get back to the long term trend line (at least!).
How long have you been 'interested' in VRS?

Best wishes - Mike

Hi Sandbag; busy time here in the Nam. Festival is around the corner and Richard has introduced Rose into the pub. Once we've got these local issues sorted and out of the way we'll be a bit more vocal.

That said, no different from a few years back, praying for Iodine price rise! It's been a while, my eldest has gone through her first set of gnashers and into her proper ones during the wait.

This though is a very welcome distraction.

Good luck and good health.

It's hard not to get very excited by VRS.

The blue sky growth opportunities are obvious.

They look to be able to deliver and crucially have the buy-in of leaders in this nascent industry (UoM, NGI, UoC/Cambridge Graphene, Haydale etc)

The stock still seems very undervalued on most metrics for judging such concept stocks and maybe a corollary of this they seem very undiscovered amongst PI and Institutional Investor communities.

Not sure how old this is , but a little insight into what graphene could do for formula 1http://www.grafoid.com/videos/graphene-has-the-potential-to-revolutionize-the-formula-one-racing-industry-and-everything-else/

[sandbag] 21/2/2017 23:21

So,
Jointer13, skylite, Spike_1 and sg1, this is where you're all hiding. Any more from the Somerset here? Hope you're all well. I am.

Bought in here the last two days and am very optimistic. GLA.

Formula One composite engineers are always looking for new materials to find the milliseconds which distinguish pole position from the rest of the field.

Our considerable experience supporting F1 Teams means we understand the need for: performance, reactivity, technical support, and innovation.

Our offer to high performance motorsport is:

Performance: Thin ply composites show significantly improved mechanical properties compared to conventional composites. (Read more on the technology page). Thin plies are necessary for multiaxial, thin skin sandwich panels and our ability to spread even ultra-high modulus fibre allows the necessary optimisation of strength and stiffness.
Reactivity: The relentless F1 calendar allows very little time between races for tuning and optimization of the car. Our high responsiveness and ability to deliver in as little as 2 or 3 days enables a Team to upgrade the car quickly. Preforms mean lamination time is minimised, allowing faster iteration.
Technical support: Our composite experts are available to help you to understand fibre options; ply weight choice; preform design; drape-ability; and processing to make your use of Thin Ply simple.
Innovation: We offer material with new fibers and new resins. We work with our customers to evaluate and tune the properties of these materials within a short timescale. This evolution is critical to ensure compliance with the changing F.I.A. regulations.
TPT® solutions can be applied to many parts of the car, from ultralight body panels to structural components.

Our success and experience in F1 projects over the past seasons makes this a strategic market for NTPT™.

[superg1] 21/2/2017 21:45

The one thing that troubles me re F1 is the time from the order to adding into the car and testing. Or it could be one part. Boullier did mention a coating for heat dissipation too.

Hey ho we'll know come Friday then if it's not that WTF are they putting it in.

[billbyrne] 21/2/2017 19:28

Yes, some clever stuff TP. Not sure I would want the grandkids bringing
these round on a regular basis though. :-)

[the prophet] 21/2/2017 18:09

That's some pretty clever and cool stuff in that post 1997 link SG1.Worth checking out SG's link re the 'Audi TT brochure hack'Amazing they can do that sort of stuff and good to see companies like Audi taking it on.

[hastings] 21/2/2017 17:44

Spoke with the CEO following the piece yesterday and suffice to say I felt it was very worthwhile.

Naturally I'm particularly excited about the Cambridge association and have to commend Billy on an excellent link.
Speaking of Cambridge and Shavian's question, I guess VRS is effectively a member, if not as yet officially there in black and white, given the alignment to Cambridge Graphene.

Nothing further to pen at present, but I do expect to revisit and add further in due course.

[luckyorange] 21/2/2017 17:43

Must admit I don't get excited about shares and had a few hard lessons on AIM, so when people were posting 50p and double that I do tend to think yeah... right!

However, graphene did get me interested in VRS and to be fair NR did have a major coup in buying Cambridge Graphene, he must have gone there and hypnotized them?

Can't quite believe that they are aware of and have access to a process that will produce 100% GNP's, isn't that what the world has been waiting for?

Having bought lower down I don't feel like a bum who knows nothing about business any more and glad that the person who said that will not be able to buy at a discounted placing to 10p as they probably hoped.

Well done all PI's who saw the possibilities here and bought in before this news, you all deserve financial success and nobody more so than Neill Ricketts, well done Neill and don't let those money men talk cheap to you.

The boot is firmly on the other foot now.

[shavian] 21/2/2017 17:21

I'm wondering why VRS is not yet a member or an associate of Graphene Flagship, the consortium funded by EU to promote research and commercialisation of graphene.

See membership list:



I note that HAYD is in there, and lots of links with Cambridge, but no VRS. Odd.

However, the Nokia spin-off Emberion OY has a UK subsidiary in Cambridge, and NR certainly has links with Prof Ferrari.

19.25p finish - exciting! No 4 on the ADVFN leader board...more...more..

[superg1] 21/2/2017 17:13

Interactive paper. They mention Novalia.

Look at this from Novalia, just one example.

[superg1] 21/2/2017 17:10

Bill

My digging revealed it was ready to go so I'm glad to see that spelt out by the main guy Ferrari.

Bu the big news within that it's it's own production method for the ink. I had questions about conductivity which are answered.

EG in the NGI ink post print it needed to be compressed.

Water based, ready to go, no changes to printing presses and the mention of rfids again.

[billbyrne] 21/2/2017 17:05

All ready to go by the sounds of it.

Andrea Ferrari, Science and Technology Officer of the Graphene Flagship and Chair of its Management Panel, stated "This is an important conceptual advance, and will significantly help the innovation and industrialization goals of the Flagship. The fact that the process is already licensed and commercialized indicates how it is feasible to cut the time from lab to market even during the lifetime of the Flagship."

[luckyorange] 21/2/2017 16:59

Well, it's nearly all out there now, just need orders and the sky is the limit!

[the prophet] 21/2/2017 16:57

excellent link billbyrne,thanks, enjoyed reading that one, lovely stuff!

[superg1] 21/2/2017 16:55

Bill

There is a lot of previously unknown detail re the ink and that article should help some get to grips with it.

[luckyorange] 21/2/2017 16:53

'The novel method uses ultrahigh shear forces in a microfluidisation process to exfoliate graphene flakes from graphite. The process converts 100% of the starting graphite material into usable flakes for conductive inks,'

Sounds like they are having to use 3 in 1 oil on the pencil sharpeners now!

[billbyrne] 21/2/2017 16:52

As you say superg1 exciting stuff, things are moving so quick at the
moment its hard to keep up. Looking forward to Friday that's for sure.
