Hello Folks,

I read about interesting packaging company in Daily Mail:

'Gift-wrapped - our packaging firm tip.'

McFarlane ticker MACF

Looked like a very good 'fit' for Nanene.

Perhaps NR has allready spoken to them.

I liked the industrial, aerospace and medical bit of the company.

I have the loan as those lending being completely oblivious and denied the true circs. So I imagine they are not very happy and as you point out it has to be repaid.

Haydale imo have been highly deceitful. Ray knew what was coming and sold shares.

He needs removing from the graphene industry now imo and should hang his head in shame, that and be prosecuted for insider trading.

[superg1] 24/2/2019 13:47

So for those that couldn't see major updates in the last news then I'm afraid you need to go to specsavers.

The truth is of course many just do a quick read and have no idea whatsoever of what is coming.

Funnily enough the casing of electrical wiring is something I have been mentioning to VRS for a while, it's a huge problem in the industry.

The wiring in a house can't cope with what could be plugged in and turned on in a typical house. They work on a diversity value of what is likely to be on at any one time, otherwise houses would have considerably larger copper wiring running through them. Heat is a big problem.

Just picking up on the interim comments about that too.

[superg1] 24/2/2019 13:42

Just to expand on Tunghsu interims comments.

Our collaboration with Tungshu is progressing with a number of projects identified. These include incorporating graphene ink in consumer heating systems, incorporating Gnanomat's technology into Tungshu's battery products and using graphene insole sensors in Tungshu's smart wearables.

Now if you look at the recent China update (I've picked out the Tungshu relevant ones)

The Company and its various current Chinese partners have agreed to progress the use of Versarien's graphene powders and inks for the following applications:

The development and manufacture of new generation graphene heaters using graphene inks.

The development of graphene-enhanced smart wearable devices, including sensors and smart earphones.

The incorporation of the Company's subsidiary, Gnanomat S.L.'s, proprietary nanomaterials into supercapacitors and lithium-ion batteries.


Now off to check out the Tungshu annual report.

Plus, the Company, taking the waterborne graphene conductive ink technology as the core, has developed the graphene electric heater, graphene heating floor and other products, and the company signed the "Strategic cooperation agreement" with Shanxi Nengtuo and Shanxi Jianbang Group to cooperate on the rural project of adopting graphene electric heating replacing the burning and heating of bulk coal in Shanxi Province.

the company has actively expanded the production of new energy vehicles and strived to build the Closed Loop of Industrial Chain of “high-end materials— Graphene-based Lithium-ion Battery-New Energy Vehicle".

The advance layout for new graphene materials is a strategic input for the company's long-term development in the future, which fits the future development direction of new materials and new energy vehicles, having the great growth potential and market space.

Superg1 re your #61,288
You did not mention the RNS of 21 Dec by Haydale to say they had issued 1.25m new shares at 20p (that £250k being included in the £961k cash balance at 31 Dec per the narrative in the interim results released on Friday but not included on face of the cash flow statement within those results). I can only think that the subscriber for those shares is just a little unhappy when only 2 months later a rescue new share issue at 2p per share is announced for 93% of enlarged share capital. The other part on financing in that RNS of 21 Dec was about a £750k loan at 11% coupon to be drawn down in Janauary that will be repaid in instalments over 16 months. That expensive loan will now be repaid from new shares and in hindsight was unnecessary.

You and I are VRS supporters and believe that VRS is investable as it will not be afflicted by the type of problems shown by Haydale and other quoted companies with graphene in their name. But newcomers to investing in graphene companies can only be made more wary of that belief by what’s happening at these other companies..

Being demostatable is key 😉

[rafboy] 24/2/2019 11:42

Isn’t it the case that once a small airline replaces their seat backs with part graphene ones, it becomes more likely that others will follow? Especially, when the weight and fuel savings are demostatable. Moreover, this logic should apply in many areas where graphene added to objects or structures improves a multitude of things. That is why VRS has such a bright future IMO.

Indeed hattie :) and toray supplied material in UoM 2D-tech carbon fibre research, innovate project and Mclaren watch came out of that i think. Atb. Ellis

29 August 2018

'Science behind world’s lightest graphene watch revealed'

Leading the research Professor Robert Young said: “In this work, through the addition of only a small amount of graphene into the matrix, the mechanical properties of a unidirectionally-reinforced carbon fibre composite have been significantly enhanced.

“This could have future impact on precision-engineering industries where strength, stiffness and product weight are key concerns such in as aerospace and automotive.”

Hattie, re yr bbc breakfast comment concerning airbus composites, would make sense given boeing going this way too per below 2019 outlook article. Both are said to be looking at redesigns in 2020. Looks like thermoplastic and metal hybrid/composite products the way forward. Toray purchased thermoplastic firm 'tencate' too. Toray are japanese, and UoM NGI members (as of 2016-current status unknown). Long article (click thru for it all), couple of graphene mentions. But an Interesting trend, one to watch ! Aimo.

Composites 2019: A multitude of markets

"The composites industry, in general, continued to show health and growth, powered particularly by the aerospace, automotive and wind energy sectors..."

Article Post: 1/1/2019


"The composites industry, in general, continued to show health and growth, powered particularly by the aerospace, automotive and wind energy sectors. Not to be overlooked however, is the marine end market, which in 2018 finally returned to pre-Great Recession health, continuing a trend begun in 2015. Mergers and acquisitions (M&A) activity in the composites industry continued to make news in 2018, highlighted in March by carbon fiber specialist Toray paying $1.1 billion for thermoplastic and thermoset prepreg specialist TenCate Advanced Composites. Toray, which had little thermoplastics capability prior to the acquisition clearly saw in TenCate a chance to stake a long-term claim on viability of thermoplastic resins in high-performance composite structures.

Indeed, the entire aerospace composites supply chain has its eyes firmly set on what is expected to be a series of new aircraft manufacturing programs, starting with the Boeing 797, which has been informally announced by the company but not yet officially launched. The assumption among composites professionals is that composites will be used extensively on this aircraft; the questions are where will they be used, and what type will be used? Wings almost certainly are a good candidate for composites. Less certain, but still probable, is the fuselage. Further, if the fuselage is composite, might it be thermoplastic?

Development of thermoplastic materials and processes for aerostructures has been significant in the last decade, particularly in Europe with efforts like the Thermoplastic Affordable Primary Aircraft Structure innovation program (TAPAS), which is evaluating the use of thermoplastic composite structures in wing, fuselage and tail applications. The appeal of thermoplastics is significant as the material can be stored at room temperature, can be processed out of the autoclave and is more easily recycled. Thermoplastics, however, are hobbled by a simple lack of familiarity — the aerospace supply chain is mostly used to working with thermoset composites, thus thermoplastics represent a departure from the norm.

On the heels of the Boeing 797, it is expected that Boeing and Airbus will announce, probably in the early 2020s, a cleansheet redesign of their single-aisle stalwarts, the Boeing 737 and the Airbus A320. This will trigger, again, a new round of material and process assessment to determine where and how composites might be used on these aircraft. The big concern with these aircraft among aerospace composites engineers is the pace of manufacturing. Airbus manufactured 55 A320s per month in 2018, and in 2019 that number will increase to 60. Boeing manufactured 52 737s per month in 2018, and in 2019 that number will increase to 57. Composite materials and manufacturing processes will have to be substantially optimized and sped up to meet this pace of manufacture. Signals from the composites industry indicate that this is possible, particularly as automated manufacturing and quality inspection systems are matured...."

And he says that compared to other discoveries, graphene is being commercialised relatively quickly. Testament to it's disruptive potential imo. Best ellis

Time to market

"It's amazing people say it's taking a long time because if you look back in history it's taken a lot longer for new tech to get to market than graphene has," says Frank Koppens from the Institute of Photonic Sciences (ICFO) in Barcelona, and the Scientific Chair of the Graphene Pavilion at last week's MWC 2018. "If you look at your smartphone, the technology inside it was invented 30-40 years ago – there are about 25 Nobel Prizes for Physics inside in there," he says. "All those inventions were made in the 1960s, and it wasn't until much later on that they found their way into consumer products."

Discovered a little over 10 years ago, it is already possible to buy products that contain graphene. "So I would say the opposite," says Koppens. "Graphene has been remarkably fast to market."

Wonder if serratia can have a look at this exeter university concrete research ? They say issues with cnt's and GO - interesting because exeter use GO in their research. Graphite flakes (24nm particles) weakened the concrete. Microfluidised flakes (average 6 layers) and gnp's (average 10-14 layers) performed the best. See figure 2 charts. Aimo. Best ellis.

'Ultrahigh Performance Nanoengineered Graphene–Concrete Composites for Multifunctional Applications'

First published: 23 April 2018

hxxps://doi.org/10.1002/adfm.201705183

Abstract

"There is a constant drive for development of ultrahigh performance multifunctional construction materials by the modern engineering technologies. These materials have to exhibit enhanced durability and mechanical performance, and have to incorporate functionalities that satisfy multiple uses in order to be suitable for future emerging structural applications. There is a wide consensus in the research community that concrete, the most used construction material worldwide, has to be engineered at the nanoscale, where its chemical and physiomechanical properties can be truly enhanced. Here, an innovative multifunctional nanoengineered concrete showing an unprecedented range of enhanced properties when compared to standard concrete, is reported. These include an increase of up to 146% in the compressive and 79.5% in the flexural strength, whilst at the same time an enhanced electrical and thermal performance is found. A surprising decrease in water permeability by nearly 400% compared to normal concrete makes this novel composite material ideally suitable for constructions in areas subject to flooding. The unprecedented gamut of functionalities that are reported in this paper are produced by the addition of water‐stabilized graphene dispersions, an advancement in the emerging field of nanoengineered concrete which can be readily applied in a more sustainable construction industry."

1 Introduction

"The new global standards of modern civil technologies, continuously requiring more demanding infrastructure, are driving the development of ultrahigh performance multifunctional construction materials. In particular, extensive efforts are focused on increasing the performance and functionality of concrete, the most used construction material worldwide. A truly step changing approach to enhance mechanical performance and to provide novel functionalities requires intervention at the nanoscale since most of the damage caused to concrete can be traced back to chemical and mechanical defects in the cement structure. Current research efforts are therefore directed at exploring new ways of enhancing the performance of concrete by nanoengineering the chemical and physico‐mechanical properties of cement, the main binding element in the composition of concrete. The cement particles, which consist of a variety of chemical elements (such as calcium silicates, aluminates, and aluminoferrites), undergo transformation from powder form to fibrous crystals upon reacting with water, known as the hydration reaction.1 Their growth and mechanical interlocking over time are the most significant factors in shaping the material properties of concrete. The outstanding chemical and physical properties of nanomaterials provide the most efficient enhancement for the internal matrix of concrete, and recent progress in nanomodification of cement composite materials has enabled applications in structural reinforcement, reduction of environmental pollution,2 and production of self‐cleaning materials.3

Previous studies4-10 have largely focused on the incorporation of nanomaterials in cement. These include the incorporation of carbon nanotubes (CNTs)7 and graphene oxide (GO)4, 5 in cement which resulted in a 50% (for CNT) and a 33% (for GO) improvement of the compressive strength, while industrial‐grade thin graphite platelets (100 nm thickness)6 were shown to improve the thermal conductivity. However, these findings do not extend directly to concrete, as the addition of sand and aggregate changes the physico‐mechanical behavior of the material. Moreover, to date the role of atomically thin materials on nanoengineering of concrete is yet to be explored, and this holds the promise to change the landscape of construction materials leading to a more sustainable urbanization with lower carbon foot print and more resilient constructions against natural disasters.

Here we report innovative few‐atoms̴8;thin graphene‐enabled nanoengineered multifunctional concrete composites which display an unprecedented range of enhanced properties compared to standard concrete. We demonstrate an extraordinary increase of up to 146% in the compressive strength, up to 79.5% in the flexural one, and a decrease in the maximum displacement due to compressive loading by 78%. At the same time, we find an enhanced electrical and thermal performance with 88% increase in heat capacity. A remarkable decrease in water permeability by nearly 400% compared to the standard concrete, which is an extremely sought‐after property for long durability of concrete structures, makes this novel composite material ideally suitable for constructions in areas subject to flooding. Finally, we show that the inclusion of graphene in nowadays concrete would lead to a reduction by 50% of the required concrete material while still fulfilling the specifications for the loading of buildings. This would lead to a significant reduction of 446 kg per tonne of the carbon emissions by the cement manufacturing. Crucially, we demonstrate that the unprecedented gamut of functionalities that we report in this paper are produced by the addition of water‐stabilized graphene dispersions, with high yield, low cost, and compatible with the large‐scale manufacturing required for the use of this material in practical applications. The unprecedented range of functionalities and properties uncovered in our study represents an advancement in the emerging field of nanoengineered materials which can be readily applied in a more sustainable, environmentally friendly construction industry...."

3 Discussion

"....Previous studies4-6, 8-10 on nanoengineering cement through the incorporation of nanomaterials such as CNTs, GO, hexagonal boron nitride (hBN), and graphite have shown improvements on the strength and thermal properties. However, the conventional approach to disperse nanomaterials in the dry cement matrix powder is costly, involves complex procedures, difficult to scale up, and can lead to degradation of the mechanical properties of concrete. Progress on reinforcing cement materials with CNT is largely hampered by their chemical incompatibility with cement hydrates.26, 27Likewise, while promising advancements have been made on GO–cement nanocomposites,4 GO reinforcement of concrete still poses major challenges. For example, GO is hydrophilic enough to absorb most of the water contained in the cement mortar, and it has been shown to hamper the proper hydration of the cement, making dispersion of the GO within the matrix difficult. The multiple steps and additives linked to the oxidation change the molecular structure of GO sheets and can introduce defects, resulting in further uncertainties in the GO–cement molecular interactions. The cost‐ineffectiveness of the method4 used for the preparation of GO–cement nanocomposites turns the production of GO–cement into a nonviable method for industrial scale production. Finally, most of the previous studies were performed on small samples of GO–cement composites that cannot be directly applied to concrete, as the addition of sand and aggregate changes the physico‐mechanical behavior of the material.

The results presented here indicate that nanoengineering concrete through reinforcement with graphene leads to concrete composites with ultrahigh strength and at the same time it widens the range of functionalities. These materials will be of particular interest for the construction industry to develop new competitive structural applications. Besides enhancing the mechanical performance, we demonstrate that the novel graphene–concrete composites satisfy multiple uses, with the added functionalities derived from the intrinsic properties of graphene. Thus, we show that graphene–concrete composites act as a barrier against water infiltration, which is an extremely desired property for long durability of concrete structures. In addition, we demonstrate enhanced thermal stability mainly through the increase in heat capacity of concrete by incorporation of graphene.

More importantly, it is evident that graphene‐reinforced concrete will have positive impact on the environment. First, when compared to other reinforcement methods such as carbon nanotubes and graphene oxide, our method of production and final product are nonhazardous. This, along with the decreasing price of graphene, due to its continuous production scaling up would allow the direct fabrication and incorporation of graphene‐reinforced concrete in the construction industry. Another way in which graphene‐reinforced concrete will have a positive impact on the environment is by contributing to the decrease of carbon emissions due to cement manufacturing. Specifically, the production of concrete accounts for up to 7% of the global CO2 emissions.28 We estimate that reducing the quantity of cement by 50% of the required concrete material, while still fulfilling the specifications for the loading of buildings, would lead to a significant reduction of 446 kg per tonne of the carbon emissions by the cement manufacturing (see Section S10 in the Supporting Information). These considerations make our graphene‐reinforced concrete a promising material for a better, more environmentally friendly construction industry...."
