Big buy order being worked in the background? Chinese? Lansted? II?

[clint fleecewood] 20/7/2020 09:39

That or big buy going through in the background. I haven't checked the trades but often you can see if they are obvs one or the other due to two price bands, even if both bands fall an one side of the mid.

[jbennett] 20/7/2020 09:26

You would think the early trades were in fact buys hence the mark up on Fridays close?

[high park] 20/7/2020 09:21

But the volume is mainly sells, and yet we're up.

[ewads] 20/7/2020 09:13

With all the anti Chinese rhetotic, you would think the China jv would be a no no.

[brassneck2] 20/7/2020 08:57

Something going on here. More volume in the first hour than on pretty much any of the last 12 trading days bar 13th July.

[aquaesulis01] 20/7/2020 08:28

Hi roger and ty for the response. I realise there have been no issues reported, just wondered whether delay in production might have been due to the fact that because we had such a mid winter with virtually no frost whether they are extending the trial through this winter in order to complete the "all weather" testing

[vs9] 20/7/2020 08:21

More volume in 10 mins than for most of the days in July??

[luckykids] 20/7/2020 08:18

Huge volume in first 10mins 1/2millionUnusual

[cotswoldsparky] 20/7/2020 07:28

It may be quiet over here on the news front but our man Jin Xin is still busy in China. You'll see him on the front row, far right at a recent event in Beijing.

It’s been a long time coming FF, but the Graphene Revolution is now upon us.

Recent article I read
There appears to be a particularly significant upside to the potential use of graphene-reinforced materials in the fuselages of commercial aircraft, according to reports coming out of the conference. In the course of a typical day, an aircraft will experience temperature swings of 60 degrees Celsius or more as it travels from ground level into the atmosphere and back down to ground level.

Airplanes are also routinely hit by lightning strikes, which can have devastating consequences. Representatives from Airbus who attended the conference said the company is dedicated to researching graphene-related materials in aerospace applications because of their potential to withstand challenging conditions.

Meanwhile, conference representatives from Fiat Chrysler said they are looking into graphene composites to create safer vehicles.

The arch was on mandatory test in Bristol and there are no issues. Daniel was very excited, I presume he would not have joined Versarien otherwise. Apart from TFL the arch has many applications elsewhere.

Hoping to add this week as funds become available.

[aquaesulis01] 19/7/2020 15:07

Does anyone know whether AECOM received a Trial certificate following the prototype demonstration of their Railway Arch?



Also bit more about the material selection process included in the attached

Of the six material options were tested the one selected for use was gASA (graphene Acrylonitrile Styrene
Acrylate), reinforced with Glass Fibre (GF). The gASA material is extruded, from pellets, with the addition of
graphene enhancing the manufacturability of the product. Details of the QA/QC process for the print/extrusion
and the thermal dynamics of the print/extrusion process were also defined at this stage. The measured material
properties for gASA were used in revised calculations and Finite Element Analysis (FEA), to consider the main
loading cases, namely self-weight, torsion, aerodynamic loading, and fatigue, which confirmed that the
maximum stresses, strains and deflections were below the allowables, with significant margin

Graphene and 2D materials can turn 'Moore's law' into the past

A group of researchers in Manchester (UK), Netherlands, Singapore, Spain, Switzerland, and the United States recently published a new study on a field of computer equipment development commonly known as ' spintronics' , which uses graphene as the foundation for making next-generation electronics.

Recent advances in theory and experimentation, as well as groundbreaking findings in spin electronics research involving graphene and related 2D (2D) materials, have drawn people's attention. into an exciting new field of research and development.

Spintronics is a combination of electronics and magnetism , at the nanoscale and could lead to the introduction of next-generation high-speed electronics. The device spins the solution viable alternative to electronic devices nano (nanoelectronic) beyond the framework of Moore's Law, with the ability to use energy more efficient and less wasteful than devices traditional electronics, which rely on electric charge. In theory, we could make phones and tablets that work with semiconductors and memory chips based on electronic spin.

The research, published in the Review of Modern Physics, focuses on new aspects of heterostructure and the phenomena associated with them.

You probably already know spintronics on laptops and PCs - these devices have been using spintronics in the form of magnetic sensors in the hard drive's reading area. These sensors are also used in the car industry.

Spintronics is a new direction to develop electronic devices, in which both memory devices (RAM) and logic devices (semiconductors) are designed to take advantage of "spin" (rotation), which is part of basic properties of electrons, making them act as tiny magnets, as well as being charged.

Dr Ivan Vera Marun, lecturer at the University of Manchester, said: " The developments related to graphene spintronics, and more broadly, 2D heterogeneous structures, have allowed us to create, transport, and detect. spin information using effects that were previously in graphene alone cannot be accessed . "

" . We believe that in the future, spin transport will be performed in 2D heterogeneous structures, even at room temperature. Such transport will allow the utilization of quantum mechanical properties. of electron wave functions, bring spin into 2D materials for use in future quantum computing devices . "

Controlling spin transport in graphene and 2D materials has been opening promising new applications in electronic devices, especially customized heterogeneous structures - heterogeneous structures. van der Waals - contains many ranges of 2D materials arranged in an orderly controlled manner. This study gives us an overview of the field of graphene spintronics research and clarifies theories and experiments related to this field.

Billions of spintronics devices such as sensors and memory chips are being produced. Every hard drive has an electromagnetic sensor that uses spin currents, and magnetic RAM chips are also becoming more and more popular.

Spintronics is a new direction to develop electronic devices.

Interesting results have been produced over the past decade in the field of graphene spintronics, and consequently further research has been carried out to expand into new 2D compounds.

Since its discovery in 2004, graphene has opened the door for other 2D materials. Researchers have since been able to use these materials to create rows of 2D materials called heterogeneous structures. They can be combined with graphene to create new design materials, to produce devices that were previously only available in science fiction works.

Professor Francisco Guinea, co-author of the study, said: " The field of spintronics, properties and spin applications in materials has brought a host of new concepts in the study of solids. The fundamental aspect of the motion of spin-carrying electrons is one of the most exciting fields in solid matter physics . "

The identity and properties of new quantum materials with unusual topology electrons and magnetic properties are being studied more and more globally after the concept of topological insulators has been shaped. founded in 2004. Spintronics is at the center of this quest. Because of their purity, durability, and simplicity, 2D materials are the best platform for finding unique topological features related to physics, electronics, and quantum magnetism. .

Overall, the field of spintronics in graphene and related 2D materials is now fast-forward, with graphene spintronics devices such as nano oscillators for applications in communication, space, and communications. High speed radio waves, car radars, and interchip communication applications.

Poor old mavvy - drinking again after another depressing week :¬( I suggest you give that last post a quick edit before a less sympathetic reader than me tries to decipher it.

Just to clear your head, you might like to look through a typical Innovate loan agreement. I'll be interested to see the vrs version, if and when it arrives...

DAveMAc3,


Yes, and it's as dry as the Sahara Dessert. I admit to giving up before the end, but there are some timeless salutary lessons about investing, and you wouldn't see him saying let's chuck my lot in on one risky AIM listed share, even if AIM had been around when he wrote the book.


The one lesson new investors need to learn is proper position sizing and a diverse portfolio, don't bet the house on one stock because a whole BB full of punters say it's a good idea, and that is the main danger of BB's, IMHO.


That's a general comment, not directed at this thread specifically,


Have you ever read comments posted on the LSE madhouse?

I doubt any of them are Buffet in disguise.........

Ok I'll give a little hint. Some organisations are openly going out and touting for business. They may even be providing the stuff for free and on some occasions it's down to knowing someone in the company so potentially some regional elements are relevant.There product may make a difference based on what it is the operational requirement is. What you will see is figures produced which may be unsubstantiated and in some cases no figures at all produced to support the benefit only the "its got Graphene" init. I think some spell graphite wrong by the way Other organisations actively seek out those with the right product to make that difference and give the very best chance of success .Now if they produce a sh1t ice cream and sprinkle salted caramel on it it's still a sh1t I've cream that is better than without.Having said that I am glad that some companies are getting some stuff to market but I'll guarantee it's not as good as it could be using what they are I know nooothing
