Is graphene starting to live up to its hype?

When graphene was first isolated in 2004 the so called “super material” was meant to change the world. The material has remarkable properties - it is 200 times stronger than steel, transparent, extremely light, flexible and also exhibits excellent electrical conductivity. Twenty years on it is starting to live up to the original hype and is being incorporated into a wide range of materials and products.
RAZOR’s Reya El-Salahi traveled to Cambridge to meet Prof. Sir Colin Humphreys, Co-founder and CSO of Paragraf, one of the first companies in the world to mass produce graphene-based electronic devices. Founded with Dr. Simon Thomas and Ivor Guiney in 2018, after a breakthrough they made at the University of Cambridge, the company now produces enough graphene to make 150,000 electronic sensors a day.
Graphene was first isolated by the University of Manchester's Prof. Sir. Andre Geim and Prof. Sir. Konstantin Novoselov. Manchester has become the UK’s home of Graphene and 2D materials research. Opening the National Graphene Institute in 2015 and the Graphene Engineering Innovation Centre - known as the ‘GEIC’ in 2018. Apart from electronics, graphene is mostly incorporated into another material to lighten and strengthen it. It’s been used in building materials such as concrete, consumer products such as plastic bottles and in trainers, and also in the automotive and aerospace industries.

Vapour Deposition is used to make Silicon Chips, that we all know and love. In a vacuum, one can make a cloud of the element that you need, but it is several atoms thick. For metals this is easy, because they melt at a particular heat level. Carbon is very different, and I don't know how they make a cloud of Carbon, that deposits only one atom thick.

This is amazing. Many people dogmatically believe that free market will solve everything - in reality the free market operates on moment. Any new ideas will have to compete with entrenched existing industries and somehow find funding with no guarantee of return generally by people with no interest in the technology, rather who just want a return. This rarely benefits totally new technologies. In the US at least there are programs to fund completely new ideas, through NSF, agriculture department, DARPA, etc. but the amount of funding supplied is usually laughably inadequate. Some friends of mine had a startup idea teach electronics and embedded programming in a novel way, they actually wln a first round NSF grant - the grant was for I think $26k. That might be enough for materials for a year or so but that's not paying for any real equipment, rent, salaries, or healthcare. The startup died.

Been curious about the research/production status of graphene for a while, as there haven't been too much about it in the news the past few years... The hype died down a bit, while the researchers and engineers were working out the kinks, I guess. Constructive feedback: I feel a few lines got repeated and/or said by several people a bit too many times; specifically the electrical properties, that's already fairly famous. Overall high quality production; got the right people to ask the questions, and had the right questions. Seem to be prioritizing the right topics to cover at the right times.... Honestly surprised this channel hasn't gotten more followers... Algorithm has been killing it, I guess...

No, the number 1 use for hall sensors is in brushless motors ( also current clamp metres). Most brushless motors have at least 1 hall sensor. Brushless PC fans use a cheap hall sensor. Joysticks use microswitches and/or potentiometers. Ive never seen a joystick with a hall sensor, Its always a potentiometer per axis. Joysticks certainly won't be using expensive graphine hall sensors anytime soon.

@stage274
@stage274 День назад
Graphene oxide promises to revolutionize lithium ion batteries. However current production methods make it cost prohibitive for mass application. Regular non oxidized, non functional graphene will not due. Regular graphene is very difficult to work with. Hates everything; not easily dispersed on substrates! Kinda good for capacitors only. This is why graphene has not changed everything as we know it yet. It’s just not functional.

Good question. The atoms in the layer are linked so they are side by side, basic hexagon shapes connected to eachother. I might be wrong with the next statement, but graphene where layers are connected to eachother are called graphite. If you take a sticky tape and stick it to a pen's lead and pull it, you have created graphene.

This is cute but Let me tell you know this will never see the light of day in leading edge chips. Anyone in the chip industry knows who is the biggest manufacturer of the leading edge chips: TSMC. And how much have they invested in silicon based manufacturing? $50B per year in last 4 years. Right. $200B of infrastructure has been put in place. It will take roughly 16 years for it to pay off. Not to mention, an entire industry of etching, dies, lasers built on Silicon as rhetoric substrate! You would have to build equipments, testing, fabs to shift to graphene. Roughly $2T dollar change. 😂Yeah that may be a hard thing to entertain. Especially because all those companies are public. Now, that being said, the paragraph company is a small foundary. They are thousands of such small scale foundaries everywhere. They do small chips, not leading edge chips that go in your iPhones or computers. And here’s the rub, it is cheaper for a lagging tech chips like cars, calculators, home pods, cameras to use silicon based chips because the capex cost by TSMC is already low due to years of manufacturing. So it would be costly for everyone to move to graphene. All the beneficial properties of graphene may be used in very niche cases. Experimental stuff. Maybe even space and Quantum Computers. QuantumC’s timeline is 12 years at the moment. It’s a good marketing video but don’t expect this in your iPhones or Google phones.

If you draw a pencil line on a paper, would you say it is 3D? And that's hundreds or thousands of molecules thick. For practical purposes, a single-atom thick layer of graphene has no nominal height. At the molecular level, it is, of course, one atom in height, but for practical application, there is no reason not to treat it as a 2D material.
@Phyde4ux
@Phyde4ux День назад
@@jerrys.9895 Well. Mathematically, a line would be 1D, not sure your point is there. A square would be 2D, again, mathematically. But we're not in the field of mathematics, this is applied science. And yes, of course a carbon atom is dimensional. To be specific, its atomic radius is 0.0914 nm... in all 3 dimensions.
@jerrys.9895
@jerrys.9895 День назад
@@Phyde4ux You proved my point with what you said. A line on paper drawn by a pencil is functionally two dimensional because it has a width (the width of the pencil tip) and a length (the length of the line). But we can shorthand it to 1D because we all understand that is how best to communicate the practical information about a drawn line. By definition, there may be no such thing as a true two-dimensional *material* that can be worked with and manipulated. That said, our experience of the world is only 3D by way of brain processing; your whole visual world is a "true" 2D reflection on the photoreceptors in your eyes. So, you can be myopic in a video explaining high-level materials science to a broad audience, relying on pedantry to muddy up the communication, or you can insist that everyone immediately learn up to your level of knowledge, without gaining them any practical benefit for the work. If you watched the whole video, you'd have even noted that they make at least two references to the "thickness" of the material, belying a third-dimension, but since we have access to the entire molecular area of the material at all times, it is for all practical applications, 2D. This is what effective science communication looks like. If a subsection of the audience becomes interested enough to research further, the nuances will become self-evident, and no one loses any meaningful information in the process.
