remind me why people wanted to get the market open?

I think you are all missing the point of Fests and Luckykids post,

SG1 has already told us how many graphite / graphene companies sort their product to make sure the sample is graphene not GNP,

post 47406

"Now that is a key point. Anyone can get put out a sample of graphene and then claim they can do high quantities. One method is to use a centrifuge to keep removing the heavier (multi-layer) graphite. In the end you have the lightest platelets which will be few layer"


VRS uses centrifuge as part of their process to separate the ionic liquid from the graphene.


The purpose of the independent third party test, is for them to collect a random sample from the production facility. not have Versarien or any other company just hand them some centrifuge graphene for them to test,

I don't believe any graphene company has recently completed this process.


From the AZO - Graphene Council Interview.


Tell us about the Verified Graphene Producer program that the Graphene Council have recently launched. What impact on the production process will this have?


The Verified Graphene Producer program is very important. We have just launched this internally. What the program involves is a physical, in-person inspection at a graphene producer's facilities. What we do while we're there, we look at the entire production process from raw material intake until the product is shipped to the customer. We look at things like their quality control processes as well as health and safety measures.

While we're there inspecting the facilities, we take a random sample from the production stream and then have this sample material characterized by a first class lab. For example, we're working with the National Physical Laboratory, or the NPL, in the UK. The tests that are performed on the material will include AFM, XPS, SEM, TEM, as well as potentially other tests to verify if the material matches the specifications published by the producer.

This is especially useful for end users. In fact, in recent discussions that I've had with major companies including; a plastics products company, an advanced engineering company, a composites producer, and others, all these end users, these buyers of material, when we shared with them that we had launched this Verified Graphene Producer program, expressed how important and valuable it would be to them having an independent third party validate a particular graphene producer.

If you look at the testing, in order to do a full materials characterization of a graphene sample costs anywhere between $10,000 to $15,000. End users or customers are simply not going to go through that process to test if the material they get from producer ‘A’ or from producer ‘Y’ meets the spec sheet.

Having this third-party validation process in place is hugely valuable, especially because today the graphene market is both confusing, because a lot of the end users don't understand the different types of graphene, and it's very non-transparent.

It's very hard for industrial companies that don't understand the nuances of different graphene materials or which supplier is reputable. The Graphene Verified Producer program is designed to bring a measure of transparency to the market.

'Waterproof Graphene Electronic Circuits Developed For Next-Gen Sensors'

 Niloy Banerjee February 11, 2019

"A team of European researchers has discovered that when this two-dimensional material is integrated with the metal of a circuit, the contact resistance is not impaired by humidity.

This finding is known to help develop a new sensors-the interface between circuits and the real world- with a significant cost reduction.

The many applications of graphene, an atomically thin sheet of carbon atoms with extraordinary conductivity and mechanical properties, include the manufacture of sensors.

These transform environmental parameters into electrical signals that can be processed and measured with a computer.

Due to their two-dimensional structure, graphene-based sensors are extremely sensitive and promise good performance at low manufacturing cost in the next years.

To achieve this, graphene needs to make efficient electrical contacts when integrated with a conventional electronic circuit. Such proper contacts are crucial in any sensor and significantly affect their performance.

But a problem arises: graphene is sensitive to humidity, to the water molecules in the surrounding air that are adsorbed onto its surface. H2O molecules change the electrical resistance of this carbon material, which introduces a false signal into the sensor.

However, Swedish scientists have found that when graphene binds to the metal of electronic circuits, the contact resistance (the part of a material’s total resistance due to imperfect contact at the interface) is not affected by moisture.

“This will make life easier for sensor designers since they won’t have to worry about humidity influencing the contacts, just the influence on the graphene itself,” explains Arne Quellmalz, a PhD student at KTH Royal Institute of Technology (Sweden) and the main researcher of the research.

The study, published in the journal ACS Applied Materials & Interfaces, has been carried out experimentally using graphene together with gold metallization and silica substrates in transmission line model test structures, as well as computer simulations.

“By combining graphene with conventional electronics, you can take advantage of both the unique properties of graphene and the low cost of conventional integrated circuits.” says Quellmalz, “One way of combining these two technologies is to place the graphene on top of finished electronics, rather than depositing the metal on top the graphene sheet.”

As part of the European CO2-DETECT project, the authors are applying this new approach to create the first prototypes of graphene-based sensors. More specifically, the purpose is to measure carbon dioxide (CO2), the main greenhouse gas, by means of optical detection of mid-infrared light and at lower costs than with other technologies.

In addition to the KTH Royal Institute of Technology, the companies SenseAir AB from Sweden and Amo GmbH from Germany are likewise participants in the CO2-DETECT project, as is the Catalan Institute of Nanotechnology (ICN) from Barcelona."

Picking out just one line from Maisto's post - regarding the Aecom deal:

"... the companies expect to make further announcements in Q1 2019..."

There are only 7 weeks left in Q1.
36 trading days.

announcements, plural

MOU SIGNED TO PROMOTE IGCC-EPEC CERTIFICATION
11-28-2018
Nov 28th, 2018, International Graphene Product Certificate Center (IGCC) attended the start meeting of “Incubation Program of Chinese Graphene Industry Leading Enterprises”, co-hosted by China Innovation Alliance of Graphene Industry (CGIA) and EPEC E-commerce platform (EPEC).

During this meeting, CEO of IGCC, Mr. Li-jun YIN signed the Memorandum of Understand together with EPEC and CGIA, aiming to promote the graphene materials and related applications to enter EPEC platform and open a worldwide market.

At the beginning of this meeting, held in the headquarter of Sinopec Group, Wen-hui GAO, general manager of EPEC and Yi-chun LI, general secretary of CGIA gave ebullient opening speeches. EPEC announced the open up of EPEC Global Graphene Products Trading Center. This center will of course become the most important bridgehead for graphene materials and related applications to enter petrochemical and other industrial fields.

Later, EPEC, CGIA and IGCC introduced their own focus and expertise, respectively. The three parties also signed the Memorandum of Understand. Each party will play their respective advantages. EPEC will provide trading platforms, global markets and financial services; CGIA will organize and recommend leading enterprises to enter this platform; IGCC will participate in the drafting of relevant standards and master the thresholds. With the efforts of all three parties, select the best from the best, jointly promote the preeminent graphene products and companies to enter the EPEC platform, and sold to global demanders.

Front Left: Li-jun YIN, CEO of IGCC; Middle: Shi-hao BIAN, vice manager of EPEC; Right: Yi-chun LI, general secretary of CGIA, Back from left: Chun-sheng WEI, Bidding Administration Office of the Materials and Equipment Department of SINOPEC; Wen-hui GAO, general manager of EPEC; Ping LI, vice secretaries of CGIA; Ming-ming WU, vice secretaries of CGIA; Guan WANG, Manager of IGCC Product Certification Department; and Chao ZHANG, Manager of IGCC Materials Certification Department.

It is reported that the EPEC Global Graphene Products Trading Center will not only covers graphene materials and related products, but also plan to include graphene raw materials (such as graphite, hydro carbons and other carbon sources). Relying on the quality guarantee method of IGCC-EPEC certification and EPEC standard (ES), all three involved parties will commit to building a global-leading-level comprehensive, one-stop trading platform for graphene materials and related products. It is believed that in the near future, high-quality graphene products will gather in EPEC platform and go global via EPEC.

Chun-sheng WEI, Bidding Administration Office of the Materials and Equipment Department of SINOPEC, Ye-qiu SUN, Director of Chemical Engineering Department of SINOPEC, Shi-hao BIAN, vice manager of EPEC, Hong-jian ZHANG, manager of Operation Center of EPEC, Zeng-feng WANG, vice manager of Operation Center of EPEC, Lin LI, major customer manager of EPEC, Yang LUO, operation manager of Operation Center of EPEC, Ping LI and Ming-ming WU, vice secretaries of CGIA, some other responsible person of related CGIA teams, Guan Wang, Manager of IGCC Product Certification Department, Chao Zhang, Manager of IGCC Materials Certification Department, and dozens of representatives from the first round of enterprises selected for “Incubation Program of Chinese Graphene Industry Leading Enterprises” attended the meeting and made in-depth exchanges.

Well said Maisto. I would also add to that, Neill’s and Versarien’s invites to join the advisory board of the NGA and the NGA Industry Council respectively.

[realcooltrader] 10/2/2019 22:42

Woody, beats our ten times over about twenty five years! We’ve only stayed at the Princesa Yaiza and TP, prefer the latter as it’s Adults Only.
Anyway, in the absence of Fest, may I just say “get that market open!”

[772] 10/2/2019 20:21

Ridicule, I'm more of a 'Lanzarote Princess' man myself, can only dream of the 'Princess Yaiza' when VRS hits the big time. I think Neill said there would be news when we least expect it, i'm not expecting anything next week!!(fingers crossed)

[horatio4] 10/2/2019 19:50

Ellissj, Thank you for your replly re NGA accreditation/verification.

[ellissj] 10/2/2019 18:50

Indeed woody. I agree with the title of this thread, and have confidence that neill and co are building a "substantial" and successful company. Neill says 'game on' at geic. They are to announce 2 more tier 1 partners. For me, The competition is healthy; the more successful geic becomes the better. As i posted earlier, the stronger the evidence case becomes, the more likely it will attract further govt support and private investments. To help develop the emerging UK graphene industry and cement manchester as a world hub. Therefore, the more likely it is further opportunities shall come vrs way, and we are well positioned to take them. :) Aimo. Best ellis
