Post 2884, Billwave talking to himself, best post yet

All scientists in Uni's now realise that a lot of the work they do must highlight commercialization opportunities.

Commercialization of any idea and process takes a lot of time and money, that is what Versarien was set up to do, take it out of Uni's and get it into the market, as anyone who has been invested in VRS over the years knows it isn't easy or straightforward and there are a lot of hurdles to overcome.

Fortunately 2D tech approached Neill and in turn China approached Versarien due to a meeting/presentation in Bath, little bit of luck involved? who knows (and we all need it from time to time) but the rest has been hard hard graft by a professional team.

Point of the post is that there are 1000's of things that can be commercialized (ARM did it) but very few that have so many opportunities to improve products, lives, greener tech and so ad infinitum.

The work has been done , even Mississippi get it now thanks to the NGA, groundwork done , next stage incoming.

Moonie ^^^.

The truth hurts, huh?

"To introduce multifunctionalities to concrete using graphene, we first prepared suspensions of graphene in water by high-shear liquid phase exfoliation of graphite powder using the surfactant sodium cholate (see Fig. 1A), resulting in surfactant functionalised graphene (FG). Fig. 1B shows the high-shear mixer used in this work. The exfoliation process occurs inside the square hole head, shown in the inset of Fig. 1B, where the rotor blade shears platelets at very high speed (up to 8000 rpm) against the square hole head. When graphite flakes are trapped in the narrow space between the rotor and the head, shear forces developed in the liquid separate the weakly (van der Waals) coupled graphene layers of graphite."

Right, the old pencil and sticky tape;)

The post 83983

"They might of bought it from 2d tech"

prompted a wee bit of research into where the Exeter uni. graphene came from. It turns out that it was made in-house.

Anyone seen the elusive bigt? Come 31st December it will still be invisible. A truly transformational year for vrs.

Fest - surely it's not what colour is on the monitor that counts, it's whether your investment has, or is giving a return, which based on many years posts here regarding your situation VRS is I understand. GLALTH, TBOB

That was really worth a post.......honestly!!

[loglorry1] 22/11/2019 09:19

@billwave ofcourse there are other types of Graphene. In one of the papers the bulls got very excited over about increased concrete strength published I think at Plymouth university they made their own graphene.

The point surely has to be that VRS graphene is far higher quality so can command a premium price. However we've really seen no evidence of that as nobody seems to want to buy it.

Great . Become a contrarian!

"They may have bought it from 2D tech" they may have, but if they did I'm fairly sure the sale would have been shouted from the roof tops, extreme exuberance has been displayed for less.

VRS is the only red on my monitor today! Out of 33 companies.

"Only vrs has genuine graphene. How many times?"

So all of the other reports of progress being made throughout the world towards a commercial use for Graphene and other 2D materials is just fantasy I presume? Someone somewhere is selling something that appears to work and it's not VRS for sure, regardless of any self proclaimed verification of their product. How many times?

[metis20] 22/11/2019 08:53

So if Exeter uni's graphene can produce the improvements reported in #83969 (see below), can VRS' products do even better?

"The graphene-reinforced concrete is produced by the addition of water‐stabilised graphene dispersions, with high yield, low cost, and compatible with the large‐scale manufacturing required for the use of this material in practical applications.
They demonstrated an extraordinary increase of up to 146 % in compressive strength, up to 79.5 % in flexural strength and a decrease in the maximum displacement due to compressive loading by 78 %. At the same time, they found an enhanced electrical and thermal performance with an 88 % increase in heat capacity.

Moreover, they proved a remarkable decrease in water permeability by nearly 400 % compared to standard concrete. This is an extremely sought‐after property for long durability of concrete structures and makes this novel composite material ideally suited for constructions in areas subject to flooding.
Finally, the researchers showed that the inclusion of graphene in currently used concrete would lead to a reduction of the amount of concrete material required by 50 % while still fulfilling the loading specifications for buildings. This would lead to a significant reduction of 446 kg per tonne of the carbon emissions from cement manufacturing.

we are on it big style...and as you know we have the quality.

"We are also trialling a new grade of concrete at the Graphene Engineering Innovation Centre and at a civil engineering institute featuring a graphene based material. These trials form part of our collaboration agreement with AECOM, along with a further four projects in China and the Middle East."
