sg,

Correct you can get galvanic corrosion with Graphene but not Hexotine. Hexotine has similar strength/permeability properties to Graphene but is non conducting.

Someone asked a question re ceramics a while back. Hexotine is better where high temperatures occur. Graphene gives up the ghost around 400 centigrade but Hexotene hangs in there to 800 centigrade.

He did . Maybe he shouldn't have? LolHoliday with gno xxxxx Partly?

It has me pondering for a moment and then I thought of the corrosion with electrical reactivity, I forget the term used for that.

Is the about right, as Hexotene is an insulator, if so good point.

Edit

Galvanic corrosion

Another cracking day for the hot air share of the year.

I didn't realise that, thanks

Didn't he say he was going on holiday to Spain?

Edit: must learn to type faster...

[festario] 30/7/2019 16:11

He's been on holiday with his kids in Spain, they are allowed some family time!

[wuzy] 30/7/2019 16:10

Is it me or have l got it wrong, Neill hasn't posted on Twitter for 4 days must be really busy.

"According to the Chinese Academy of Sciences, China paid $300 billion in 2014, or roughly 3% of its gross domestic product, on corrosion." You can see why they want to get theirs hands on some good quality graphene!

i reckon we are due a bolt out of the blue!

Scumbag anley? Superg is a bad influence!

[anley] 30/7/2019 15:21

Price the stuff in the country you are selling to in their currency......

its easy for them to send that to the UK bank...........

making sure that VRS gets the best rates on conversion with one of the new banks and not the scumbag banks such as RBS/HSBC/Lloyds etc etc.

[mavfav] 30/7/2019 15:16

Get well soon Mike B and thanks for the updatesI agree we need to be able to proactively seek and address the existing infrastructure and initiate controlled downtime rather than scrambling and causing disarray when it fails.I have no doubt these are all risk acknowledged and accepted yet not held to account I know nooothing

[pshevlin] 30/7/2019 15:14

A slight concern for me is that this may be marked down a bit in line with the £ even though most of the sales will be to other countries. Does anyone know what we denominate our products in these days. Perhaps it should be dollars but I seem to remember Neill saying it depends on who we are selling to. I would certainly rather that I could spend my ill-gotten gains anywhere in the world without having to depend on UK currency movements.

[superg1] 30/7/2019 14:49

Yes run away, the countdown is on.

[realcooltrader] 30/7/2019 14:46

O/T "First shalt thou take out the Holy Pin, then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then lobbest thou thy Holy Hand Grenade of Antioch towards thy foe, who, being naughty in My sight, shall snuff it."

In general great! I suspect we're involved but are we ? Yet ?

3D printable 2D materials based inks show promise to improve energy storage devices

For the first time, a team of researchers, from the School of Materials and the National Graphene Institute at The the University of Manchester have formulated inks using the 2D material MXene, to produce 3D printed interdigitated electrodes.

As published in Advanced Materials, these inks have been used to 3D print electrodes that can be used in energy storages devices such as supercapacitors.

MXene, a ‘clay-like’ two-dimensional material composed of early transition metals (such as titanium) and carbon atoms, was first developed by Drexel University. However, unlike most clays, MXene shows high electrical conductivity upon drying and is hydrophilic, allowing them to be easily dispersed in aqueous suspensions and inks.

Graphene was the world’s first two-dimensional material, more conductive than copper, many more times stronger than steel, flexible, transparent and one million times thinner than the diameter of a human hair.

Since its isolation, graphene has opened the doors for the exploration of other two-dimensional materials, each with a range of different properties. However, in order to make use of these unique properties, 2D materials need to be efficiently integrated into devices and structures. The manufacturing approach and materials formulations are essential to realise this.

Dr Suelen Barg who led the team said: “We demonstrate that large MXene flakes spanning a few atoms thick, and water can be independently used to formulate inks with very specific viscoelastic behaviour for printing. These inks can be directly 3D printed into freestanding architectures over 20 layers tall. Due to the excellent electrical conductivity of MXene, we can employ our inks to directly 3D print current collector-free supercapacitors. The unique rheological properties combined with the sustainability of the approach open many opportunities to explore, especially in energy storage and applications requiring the functional properties of 2D MXene in customized 3D architectures.”

Wenji and Jae, PhD students at the Nano3D Lab at the University, said: “Additive manufacturing offers one possible method of building customised, multi-materials energy devices, demonstrating the capability to capture MXene’s potential for usage in energy applications. We hope this research will open avenues to fully unlock the potential of MXene for use in this field.”

The performance and application of these devices increasingly rely on the development and scalable manufacturing of innovative materials in order to enhance their performance.

Supercapacitors are devices that are able to produce massive amounts of power while using much less energy than conventional devices. There has been much work carried out on the use of 2D materials in these types of devices due to their excellent conductivity as well as having the potential to reduce the weight of the device.

Potential uses for these devices are for the automotive industry, such as in electric cars as well as for mobile phones and other electronics.

Advanced materials is one of The University of Manchester’s research beacons - examples of pioneering discoveries, interdisciplinary collaboration and cross-sector partnerships that are tackling some of the biggest questions facing the planet.

Hope you are feeling better soon Mike - strongly echoed by all of us on this board I am sure.

[ad631] 30/7/2019 12:53

Not too sure I like the 'will prob' much prefer 'I will' with regards future Doc holiday interviews - I warm to modesty.

[mikebrenner] 30/7/2019 12:08

Thanks for the kind messages from the Doc Holiday interview ... will prob do a few more in future.

Been off work ill since investor event so nothing to add from the excellent updates by graham and roger about the day. All in all very positive esp hearing from the client their perspective of the VRS team and how their graphene can help solve problems for their partners.

Excellent progress on textiles with LOI - possibly the fastest segment that can be commercialised at scale due to scalable manufacturing process to add graphene inks to textiles.

Couldn’t not post this little snippet of news today that is v positive for us vrs shareholders. Our infrastructure needs updating!

O/T,

There is a Science Party, they put up a candidate to stand against the Tory MP David Tredinnick who believes in astrology and homeopathic medicine. He's also critical of science !
Somehow he became a member of the Health Select Committee and was co-opted into the Science and Technology Select Committee.
In 2009 he told Parliament that blood does not clot under a full moon.
This guy has a role in governing the country !

At the last election he had an 18,000 majority. There must be some strange voters in Bosworth Leicestershire. The Science Party got 0.4% of the vote. I wonder what DT thinks of Graphene.
