Kinda like LEDs. We could produce red and green LEDs for decades. But without blue LEDs we couldn't make white LED. So green and yellow LEDs were just useless and people thought LEDs would never become a reality until one day an unexpected breakthrough happened.
The graphene batteries on HobbyKing right now are only ~10% lighter, but due to less electrical resistance generate substantially less heat and can therefore be discharged/charged faster, or not need cooling at all. Teslas wouldn't need a cooling system for their batteries.
First time i used one was with a spot welder pulling 250+ Amps. I was pretty sure it was going to catch fire, but it didnt even get warm the battery can handle 500+ Amp draw, its wild. Never thought i would be able to pull that kind of power from a lithium battery the size of a pack of ciggs. (I used to use big 12v lead acid batteries)
well "only" 10% lighter is pretty huge for a technology that is completely new, considering lithium batteries have many decades of development behind them

I can't believe it's taken 20 years to start to see real development of some of the products. Hopefully I'll be alive long enough to see this and other 2D materials relatively commonplace. So the next 20 years or so had better be innovative! ;)

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.
The said in the video that it is a mixture of a few different carbon compound gases which react together on the 1000 degree surface of the deposition substrate, releasing the non-carbon elements in some other compound, presumably
If you have done the salt / sugar crystal growing experiment where the crystals are 'grown' as the temperature drops , then I would expect the temperature of the substrate to be slowly lowered so that the cloud of disassociated atoms can grow the flat crystal. A slight electrical charge could promote deposition.
For diamond growing, some use co2 and use electricity and plasma in a particular way to eject the oxygen atoms when they come in contact with the crystal structure. I suspect it is similar with graphene.

There's a concept known as Amara's Law (people tend to overestimate the short-term impact of new technologies while underestimating their long-term effects.) It indicates that many if not most technological breakthroughs/discoveries take years, often decades before they make significant inroads in everyday life. Electricity, the telephone, the automobile, the transistor, the Internet to name just a few examples. It was decades after development/invention/discovery that each of these were commonplace. Graphene "discovered" in 2004, it's now 2024 and it's just making a few inroads. By 2044 we'll wonder how ever did without it.
Don't forget that it took 80 years after the invention of the fridge before you could buy one in a store. (And it was actually a freezer that made ice)
@@lordgarion514 That may be but I strongly doubt it would take that long to be found on cellphones, laptops and computers in general. Once it's available every single company in those areas would kill for the opportunity to sell you one of these, as long as the cost of manufacturing it doesn't exceed the potential financial gain.
Anyone who knows graphene, knows that it is a lot easier and safer to use when in a liquid suspension, as opposed to dry powder. Unfortunately, most liquid suspension products contain no more than 15g of graphene per GALLON of product. At NanoCrete, we have completely upended this paradigm with our X15 graphene jelly product. We suspend over 480 g of graphene PER GALLON with our proprietary, 18-month shelf-stable technology, ensuring you can utilize consistent graphene safely and for longer.
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.
Yeah we need a new system that promotes innovation much better. If startups do manage to get funding, it’s usually from venture capitalists who will bleed the company dry.
@@thecsslifeWe already have the systems to do this, we just need to fund them. But like everything else, we’ve let the rich evade paying their fair share and convince us to cut funding for all public works to the bone. So now our programs simply can’t give out adequate awards, and it can’t give out enough of them. We don’t need to reinvent the wheel. All we have to do is adequately fund the system we already have.
Exactly 💯 %. Documentaries should not have a background music, instead ; a calm, specialist or highly knowledgeable reporter, a video displaying understandable circumstances, blending its original sound
This video needs far higher global views. The technology is already making our lives better, what will it be like in the next 20 years? I hope I live long enough to see it.
Hall sensors are mostly used to measure current in a wire. The current measurement is usually digitized and accumulated/integrated in order to monitor and control battery systems.
Such a top quality show. I'm surprised there's only 14.2k subscribers to the channel right now. Guess I'm one of the early ones to discover it. Keep it up, I'm betting you're about to explode soon.
Textiles, clay pottery, knapped flint, paper, oh the horrors of new materials technology! Any of us can cherry pick. It's not the exclusive right of fearmongers.
"Without being specific" it can help improve batteries. Sounds like it will be another decade before any of us experience graphene's effect on our lives...
That is why it is called a discovery and not an invention. The advancement comes from identifying the possible usecases of the already present substance.
I doubt you will ever get those even though diamond coatings are an industry standard in optics. It is better for spectacle manufacturers to keep everyone on a 1~3 year replacement schedule for glasses than to provide a longer lifecycle product. Also better for your eyes and things like driving safety to change your prescription more regularly as your eyesight ages.
im sort of disapointed when graphine was discowerd i was in my fourties i was looking forward to see the nano material revolutionizing th world now in my sixties im not sure if i could have the chance of seeing graphine revolution nuclear fusion or see watter disalination
There have recently been great leaps in desalination technology. I know one for three isn’t the best but i think it can be a new pillar of society. I’m glad you made it this far. Much love
practical application of nuclear fusion is getting relatively closer, probably in 5 years we can have small working modules that can supply power for 1 entire city. we all know what the REAL problem are when it comes to revolutionary tech. imagine nuclear fusion and its effect on fossil fuel power plants. these industries won't let new players come in that easily and take profit away. same problem why renewable energy research is taking too long even though we've had the tech and capability for decades now. politics and businesses hinder real progress.
@@illumi1011 same story it’s always been. They’re making money hand over fist and would like to continue doing so. So any innovation in energy is actively suppressed. They create propaganda to appease us. They lie right to our faces.
Sepsis detection was also solved by the Swiss company abionic - they do it in 5 minutes - but I think they could use these sensors in their equipment. Fantastic development.
Graphene seems to be have the same hype sales pitch as Teflon did back in the day. I really have fears that it may be even worse for the environment and health of our planet.
The method they use to manufacturer it may have potential issues, but the substance itself is literally the most abundant solid in the universe. And tbh, you wont be able to see it anyway :P
That depends, is graphene harmful as plastic? worse?, or neutral, graphene is carbon, so it shouldn't be like plastic, I think is a better replacement for plastic, if you can make it at scale.
I was thinking about that too, however, I think that grapheme infused plastic might be more useful than ordinary plastic for detection, properties and recycling.
@@Voltaje_YT Maybe the harm from a microplastic is not that it 'is plastic' - but that it is small enough to pass through animal permeable barriers , chemically stable enough to persist, cause inflammation etc. In which case, graphene might be just the same. But you already have an opinion on this without looking at studies or data....
For this to be a pressing problem, while the production volumes remain a trillion times less than ordinary plastics, it would have to be toxic beyond all comprehension. If the dose is the poison, factors of one trillion should not be idly discarded. Just my two femtocents on the problem.
We are talking about astonishingly minuscule quantities of graphene used in soles and tarmacs, plus it's just a fine layer of carbon an atom size width, so I'd say the environmental impact would be close to zero.
it is worth noting that it took at about15 years from the Bardeen & Bratton's transistor to appear in usable devices like portable radios, and that was on the back of years of research making pure enough crystals. So you can bet we won't see computors using graphene chips rivalling Silicon before the mid 2030s even at todays breakneck pace. Even in military evirons, which demand performance any any price.
To be honest, who cares? Silicon based computing power still hasnt reached its physical limitations and probably wont until the year 2040 or so. That means graphene has yet another 15 years to progress to becoming a viable alternative. Adoption takes time too so we will be fine in that regard till the year 2060 or so and after that computing should be „solved“ or close to it. And dont forget the impact AI can have in the years ~2030-2035 and that will most likely advance progress even faster.
@@Slayer666th Oh, there will be limitations in silicon, so niche applications will appear in other metals. Graphene Hall effect looks to be one. Some of us remember when HDD were touted to replace tape drives, and we scoffed. Tape is still around. & cheap. Horses for courses. Silicon may hold its ground in audio with analogue, but CPUs? An atom is an atom, and that is a limitation. Far more worrying is the energy used in servers/mining/AI and that gets you back to the size of the atom, eventually.
I've been so excited about graphene since I first heard about it years ago. It is now known that as it is made from carbon, we can flash burn general household waste to create it! Also, given the information on this video regarding the sensors made to detect different bacteria and virus, I know there is an ongoing attempt to create a Star Trey style medical Tricorder - a fictional device which is used as a handheld medical scanner - and I can see how graphene could be a game changer for that!
It's not a new material it's been around for a long time we've been waiting for the price to get to a reasonable level so we could actually use it in all the ways we want to
If graphene can be used in semiconductor, that would be a blessing. AI chips are expected to push power consumption thru the roof. Graphene in semiconductor with reduce that demand.
The main reason gaphene hasn't already come to the forefront is because Silicone is not only currently cheap and easy to produce.. it also still sits nicely with the technology advancement line, one, we're still able to advance using the stuff.. Silicone however is closing in on its limits, we are down to about 3nm in the domestic market, and heat Vs energy transfer is becoming a problem, with cooling solutions actually going backwards *large cooling solutions to keep silicone chips cool*.. For this reason we are not far away now from the next best thing, which may well be graphene otherwise tech advancement will halt and that isn't acceptable. I think theres a manufacturing issue with graphene aswell *mass production* but I'm sure they will iron that out
It's nice to see Manchester is in the lime light again. It was at the forfront of British computers. Also, microprocessors, the silicone on saphire F100L made by Ferranti, who were developing the F200L. Unfortunately, we are great at inventing products, but our financial system hinders the development. Leading to these being sold off to foreign competitors.
Good show with (for me at least) the right level of technical information to enable me to understand the fundamentals and their links to the applications.
It's strong and lasts longer than microplastics so that's plus. Ohh wait we already have something stronger than microplastics in our lungs silica or sand in the form of dust.
Graphene has been in industrial use for well over 15 years that I'm aware of and Swnts for 25 a bunch of swnt data was rechecked against graphene as it's a million times easier to produce in ugly format. To what you refer is the jump in quality manufacturing and classification we use bulk sluice graphene in everything from concrete to carbon fibre. In carbon composites 2% can give a 20% stronger product if you use swnts or 5-10 just as graphene. Also used to help promote self healing in high calcium carbonate concretes that breath co2 and heal cracks over time. And swnts have been used as nucleation sites in lab smelted focal magnets. So many applications aside from purely nano electronics.
Im going to show this video to my granddaughter... she will never hear about this breakthrough in elementary or high school... don't want her to wait ten years to learn about this substance1
Probably, because this video only talks about and focuses on the use of graphene but for electronics, it is not other aspects like the example you gave.
This report would have been so much better without the loud background music. Any sound engineer would have used dynamics side-chaining to control the voive-to-music levels
Something important that it doesn’t seem like they explain here is that in computers energy efficiency = speed. Generally cpus are limited by the heat they put out, and basically all of the energy a cpu uses is turned into heat. If you make less heat while computing more you have a faster cpu. The heat, ie the energy efficiency is what limits our computing.
I really hope graphene doesnt turn out to have health risks. Asbestos was the graphene of the last century. We really need a wonder-material right now.
I use a Hall Effect transistors on my automatic arduino blinds. It counts how many times the blind has turned round using a magnet glued onto the blind end.
Supposedly it biodegrades when exposed to digestive enzymes but information is extremely thin. Still, given the advantages in electronics the drawbacks may be worth it.
Something that would have served humanity as a whole *GREATLY(!)* is if they had done research on the health implications of so called "forever chemicals" *BEFORE* it was released into circulation. Now, they're everywhere and they're making us sick. So ... has anyone done any health research on graphene finding their way into humans? As great as this technology is, can we at least *try* and learn from past mistakes?
plasma sputtering isn't any big secret but the order in which they inject the molecules and how much so the ratio occurs correctly definitely a "trade secret" when developing things like this.
Interesting how they develop it and other materials. It can be used in electronics. Especially computers and chip making applications would bring the most benefits. The other applications seem like trendy thing to add graphene to everything even when it is extremly pricy
What a vacuous, vague statement. Did you think people are going to devote their lives and money to give you something for free? How entitled are you exactly?
Very cool. Tho, i was hoping to see graphene being produced in continuous sheets. Some perhaps several hundred miles of the stuff wound on a small spool. (Which must be good for something, like space elevators.😄)
I’ve been waiting since like 2012 or something. I’ve seen CAT brand power tools have graphene batteries. They are like 3x the size of dewalt power stack and way heavier and more expensive. I still think once they can get it more practical it’s going to change the world
1:11 the old man is wearing protectives when the actual workers behind him clearly are not wearing them. so from the getgo this is showing its self as something it is not. when it comes to the powerdraw of current hall effect sensors the amount is so little as it is. it is one of the components we make that uses the least from what i know at least. so the gain may not matter as much as you might think by the way the lay it out for you here.
@@dagon_hydrA what format do u want? did not say it was not special did i? said it does not matter. current ones use so little energy that their sales point on energy use is as futile as resistance to the borg ;)

(And it was actually a freezer that made ice)
@@lordgarion514 That may be but I strongly doubt it would take that long to be found on cellphones, laptops and computers in general. Once it's available every single company in those areas would kill for the opportunity to sell you one of these, as long as the cost of manufacturing it doesn't exceed the potential financial gain.
On that note, let me go and get me some NanoXplore (NNXPF • OTCMKTS) shares. They are headed in the right direction.
Anyone who knows graphene, knows that it is a lot easier and safer to use when in a liquid suspension, as opposed to dry powder. Unfortunately, most liquid suspension products contain no more than 15g of graphene per GALLON of product. At NanoCrete, we have completely upended this paradigm with our X15 graphene jelly product. We suspend over 480 g of graphene PER GALLON with our proprietary, 18-month shelf-stable technology, ensuring you can utilize consistent graphene safely and for longer.
Great, now fuckers are putting ads in the comments.
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.
Yeah we need a new system that promotes innovation much better. If startups do manage to get funding, it’s usually from venture capitalists who will bleed the company dry.
@@thecsslifeWe already have the systems to do this, we just need to fund them.
But like everything else, we’ve let the rich evade paying their fair share and convince us to cut funding for all public works to the bone. So now our programs simply can’t give out adequate awards, and it can’t give out enough of them.
We don’t need to reinvent the wheel. All we have to do is adequately fund the system we already have.
How does background sound improve our hearing of what’s being said in this presentation ?
Interesting, thanks. However, I had to turn off because of that annoyingly loud background music
Winer, boo who
Exactly 💯 %.
Documentaries should not have a background music, instead ;
a calm, specialist or highly knowledgeable reporter, a video displaying understandable circumstances, blending its original sound
Turn on cc and set volume to zero.
@@mrspeigle1that works, but it shouldn’t be necessary. Hearing the voices aids in comprehension. Everybody’s brain works differently.
How are you listening? Cell? Buds? TV? Loud ? Queit volume? It might be a eq on the device. Trying to help
We're still too busy putting it on tape and looking at it under a microscope for the cameras.
CGTN produce really quality documentaries like this one. Thank you.
So glad to know so much progress is being made.
Thank God there are people like this in the world!
This video needs far higher global views. The technology is already making our lives better, what will it be like in the next 20 years? I hope I live long enough to see it.
Now I know how a hall effect joystick works and how is made do why is so precise and expansive.
Hall sensors are mostly used to measure current in a wire. The current measurement is usually digitized and accumulated/integrated in order to monitor and control battery systems.
Such a top quality show. I'm surprised there's only 14.2k subscribers to the channel right now. Guess I'm one of the early ones to discover it. Keep it up, I'm betting you're about to explode soon.
"It's going to change the World".. I have heard that one before... R.I.P. Theranos... I wish it can become true, this tme, indeed
exactly
Lead, Plastics, Asbestos. All revolutionary and popular with ubiquitous usage... What Happens next?
Exactly- no one ever thinks about issues to deal with later and try to address those up front.
Textiles, clay pottery, knapped flint, paper, oh the horrors of new materials technology!
Any of us can cherry pick. It's not the exclusive right of fearmongers.
"Without being specific" it can help improve batteries. Sounds like it will be another decade before any of us experience graphene's effect on our lives...
At least
Graphene's been in earbud drivers for years. In this video she the narrator says it's currently in 40 million products.
you guys should maybe try to normalize the volume levels of your videos
Amazing. Nobody trusted graphene until very recently so its good to see actual research being done with trust
The amazing discovery was made with two objects, a piece of cellotape & a block of graphite. Nobel prize worthy apparently.
You didn't think of doing it.
Watch the video dude. Its not that simple.
That is why it is called a discovery and not an invention. The advancement comes from identifying the possible usecases of the already present substance.
i am, still waiting for my diamond coated scratch proof glasses from 30 years ago so i doubt this .
I doubt you will ever get those even though diamond coatings are an industry standard in optics. It is better for spectacle manufacturers to keep everyone on a 1~3 year replacement schedule for glasses than to provide a longer lifecycle product. Also better for your eyes and things like driving safety to change your prescription more regularly as your eyesight ages.
@@MadnessQuotient yes but it had the same headlines 30 years ago ..`game changing...
I just want a non-tear fleshlight, I promised myself watching this video
Cool, nice to see graphene take off . . . @ 14:24 pizza bag keeps it oven fresh for days + future oven
it's nice to see this, in theory, if we could find the right material, a logic gate could be constructed with a solitary atom :)
Love how the non descript medical use is smoothed over
im sort of disapointed when graphine was discowerd i was in my fourties i was looking forward to see the nano material revolutionizing th world now in my sixties im not sure if i could have the chance of seeing graphine revolution nuclear fusion or see watter disalination
There have recently been great leaps in desalination technology. I know one for three isn’t the best but i think it can be a new pillar of society. I’m glad you made it this far. Much love
practical application of nuclear fusion is getting relatively closer, probably in 5 years we can have small working modules that can supply power for 1 entire city. we all know what the REAL problem are when it comes to revolutionary tech. imagine nuclear fusion and its effect on fossil fuel power plants. these industries won't let new players come in that easily and take profit away. same problem why renewable energy research is taking too long even though we've had the tech and capability for decades now. politics and businesses hinder real progress.
@@illumi1011 same story it’s always been. They’re making money hand over fist and would like to continue doing so. So any innovation in energy is actively suppressed. They create propaganda to appease us. They lie right to our faces.
Nuclear fusion, always 5 years away for 30+ years and counting.
becaus the ecos are against technology and industry, they only care about there climate and drugs
Sepsis detection was also solved by the Swiss company abionic - they do it in 5 minutes - but I think they could use these sensors in their equipment. Fantastic development.
0:38 Did anyone else dab their forehead with a handkerchief?
I am still waiting for the revolution RAZOR.
Graphene seems to be have the same hype sales pitch as Teflon did back in the day. I really have fears that it may be even worse for the environment and health of our planet.
The method they use to manufacturer it may have potential issues, but the substance itself is literally the most abundant solid in the universe.
And tbh, you wont be able to see it anyway :P
That sepsis device, is incredible
Added to shoe soles and tarmacs… becoming the next environmental microplastics?
That depends, is graphene harmful as plastic? worse?, or neutral, graphene is carbon, so it shouldn't be like plastic, I think is a better replacement for plastic, if you can make it at scale.
I was thinking about that too, however, I think that grapheme infused plastic might be more useful than ordinary plastic for detection, properties and recycling.
@@Voltaje_YT Maybe the harm from a microplastic is not that it 'is plastic' - but that it is small enough to pass through animal permeable barriers , chemically stable enough to persist, cause inflammation etc. In which case, graphene might be just the same. But you already have an opinion on this without looking at studies or data....
For this to be a pressing problem, while the production volumes remain a trillion times less than ordinary plastics, it would have to be toxic beyond all comprehension. If the dose is the poison, factors of one trillion should not be idly discarded. Just my two femtocents on the problem.
We are talking about astonishingly minuscule quantities of graphene used in soles and tarmacs, plus it's just a fine layer of carbon an atom size width, so I'd say the environmental impact would be close to zero.
it is worth noting that it took at about15 years from the Bardeen & Bratton's transistor to appear in usable devices like portable radios, and that was on the back of years of research making pure enough crystals. So you can bet we won't see computors using graphene chips rivalling Silicon before the mid 2030s even at todays breakneck pace. Even in military evirons, which demand performance any any price.
To be honest, who cares?
Silicon based computing power still hasnt reached its physical limitations and probably wont until the year 2040 or so.
That means graphene has yet another 15 years to progress to becoming a viable alternative.
Adoption takes time too so we will be fine in that regard till the year 2060 or so and after that computing should be „solved“ or close to it.
And dont forget the impact AI can have in the years ~2030-2035 and that will most likely advance progress even faster.
@@Slayer666th Oh, there will be limitations in silicon, so niche applications will appear in other metals. Graphene Hall effect looks to be one. Some of us remember when HDD were touted to replace tape drives, and we scoffed. Tape is still around. & cheap. Horses for courses. Silicon may hold its ground in audio with analogue, but CPUs? An atom is an atom, and that is a limitation. Far more worrying is the energy used in servers/mining/AI and that gets you back to the size of the atom, eventually.
@@Slayer666th Silicon progress already broke down when the Dennard scaling ended around 15-20 years ago. Dark silicon problem.
That’s one exemplary professor , wearing his eye protection 🥽 at all times
I've been so excited about graphene since I first heard about it years ago.
It is now known that as it is made from carbon, we can flash burn general household waste to create it!
Also, given the information on this video regarding the sensors made to detect different bacteria and virus, I know there is an ongoing attempt to create a Star Trey style medical Tricorder - a fictional device which is used as a handheld medical scanner - and I can see how graphene could be a game changer for that!
"to see how graphene is used in the world i came to this lab here" 😂 see you in 5 years
My friend, there are other labs ;)
Buddy the products are already out there. In 5 years this stuff will be common already. This isn't 10 years ago when the products didn't even exist.
Good job, the author knows his stuff.
It's not a new material it's been around for a long time we've been waiting for the price to get to a reasonable level so we could actually use it in all the ways we want to
Best video. Thank you to everyone who made this video
If graphene can be used in semiconductor, that would be a blessing. AI chips are expected to push power consumption thru the roof. Graphene in semiconductor with reduce that demand.
Keep dreaming.
The main reason gaphene hasn't already come to the forefront is because Silicone is not only currently cheap and easy to produce.. it also still sits nicely with the technology advancement line, one, we're still able to advance using the stuff..
Silicone however is closing in on its limits, we are down to about 3nm in the domestic market, and heat Vs energy transfer is becoming a problem, with cooling solutions actually going backwards *large cooling solutions to keep silicone chips cool*..
For this reason we are not far away now from the next best thing, which may well be graphene otherwise tech advancement will halt and that isn't acceptable. I think theres a manufacturing issue with graphene aswell *mass production* but I'm sure they will iron that out
It's nice to see Manchester is in the lime light again.
It was at the forfront of British computers.
Also, microprocessors, the silicone on saphire F100L made by Ferranti, who were developing the F200L.
Unfortunately, we are great at inventing products, but our financial system hinders the development.
Leading to these being sold off to foreign competitors.

How did she miss the most common use for hall sensors there used in brushless motors
Good show with (for me at least) the right level of technical information to enable me to understand the fundamentals and their links to the applications.
It is only with the heart that one can see rightly, what is essential is invisible to the eye.
I am very happy to have nanographene in my lung beside microplastics. Thank you! 😊
It's strong and lasts longer than microplastics so that's plus. Ohh wait we already have something stronger than microplastics in our lungs silica or sand in the form of dust.
You are welcome…
you probably already had some from soot and smoke from wood and coal
We are made of carbon. and graphene is carbon. you're welcome. now go play in the sandpit.
@@Fanta....Benzopyrene is also made of carbon. That doesn’t make it safe.
Graphene has been in industrial use for well over 15 years that I'm aware of and Swnts for 25 a bunch of swnt data was rechecked against graphene as it's a million times easier to produce in ugly format. To what you refer is the jump in quality manufacturing and classification we use bulk sluice graphene in everything from concrete to carbon fibre. In carbon composites 2% can give a 20% stronger product if you use swnts or 5-10 just as graphene. Also used to help promote self healing in high calcium carbonate concretes that breath co2 and heal cracks over time. And swnts have been used as nucleation sites in lab smelted focal magnets. So many applications aside from purely nano electronics.
The discs are great, but there's a technology that allows graphene deposition along a long ribbon.
Im going to show this video to my granddaughter... she will never hear about this breakthrough in elementary or high school... don't want her to wait ten years to learn about this substance1
Nobody mentions water filtration. Much better than RO.
Probably, because this video only talks about and focuses on the use of graphene but for electronics, it is not other aspects like the example you gave.
Nobody. 23:55
Mind control
Graphene is so cool. I am especially interested in the low power and high performance semiconductor properties of it.
The biggest problem Graphene has is that it is not a semiconductor.
My mountain bike tyres (Vitorria) contain graphene. Widely regarded and reviewed as grippy, fast rolling, and long lasting
It seems that carbon nanotubes are better suited for this.
Nothing makes me feel more giddy for a new technology when its touted to beat "The Climate Crisis" 😒🙄
This report would have been so much better without the loud background music. Any sound engineer would have used dynamics side-chaining to control the voive-to-music levels
Something important that it doesn’t seem like they explain here is that in computers energy efficiency = speed. Generally cpus are limited by the heat they put out, and basically all of the energy a cpu uses is turned into heat. If you make less heat while computing more you have a faster cpu. The heat, ie the energy efficiency is what limits our computing.
I See lots of Gold on these wafers . I hope for the better this changes Humanity .
I really hope graphene doesnt turn out to have health risks. Asbestos was the graphene of the last century. We really need a wonder-material right now.
I use a Hall Effect transistors on my automatic arduino blinds. It counts how many times the blind has turned round using a magnet glued onto the blind end.
Is it recyclable? Is it degradable? Is it safe or more like a plastic issue?
Supposedly it biodegrades when exposed to digestive enzymes but information is extremely thin. Still, given the advantages in electronics the drawbacks may be worth it.
Something that would have served humanity as a whole *GREATLY(!)* is if they had done research on the health implications of so called "forever chemicals" *BEFORE* it was released into circulation. Now, they're everywhere and they're making us sick. So ... has anyone done any health research on graphene finding their way into humans?
As great as this technology is, can we at least *try* and learn from past mistakes?
The power companies won’t like this , but the consumer will.
There are 348 downvotes on this. I need somebody to explain that, because this all seems like genuinely interesting science being done.
What a fantastic age we live in.
and how much energy do we need to make graphene compared to how much energy will it save if its in every pc?
Well it’s about time. Thanks for the update.
id like to buy a hall sensor, love to see the resolution and if it could improve an idea i have
Some of the component packaging is 35 years old.
Who wold like to see terestrial and aerial vehicles changing in different forms and shapes ? 👇
plasma sputtering isn't any big secret but the order in which they inject the molecules and how much so the ratio occurs correctly definitely a "trade secret" when developing things like this.
Also HDPE can break down into micro and nanoplastics.
If graphene becomes the new wonder material, what will be the environmental impact of its potential ubiquity?
carbon is the most prevalent molecule in the universe.
I now love the color blue.😊
Interesting how they develop it and other materials. It can be used in electronics. Especially computers and chip making applications would bring the most benefits. The other applications seem like trendy thing to add graphene to everything even when it is extremly pricy
I fail to recognize how this is exciting news for regular people, in the world where corporations are tightening their death grip on humanity.
What a vacuous, vague statement. Did you think people are going to devote their lives and money to give you something for free? How entitled are you exactly?
@@ElectronFieldPulse Science works for the development of all mankind, not for the boss's pocket.
Very cool. Tho, i was hoping to see graphene being produced in continuous sheets. Some perhaps several hundred miles of the stuff wound on a small spool. (Which must be good for something, like space elevators.😄)
I’ve been waiting since like 2012 or something. I’ve seen CAT brand power tools have graphene batteries. They are like 3x the size of dewalt power stack and way heavier and more expensive.
I still think once they can get it more practical it’s going to change the world
Very informative video, but why those annoying background sound effects?
1:11 the old man is wearing protectives when the actual workers behind him clearly are not wearing them. so from the getgo this is showing its self as something it is not.
when it comes to the powerdraw of current hall effect sensors the amount is so little as it is. it is one of the components we make that uses the least from what i know at least. so the gain may not matter as much as you might think by the way the lay it out for you here.
You're right. There's nothing special about this hall sensor at all. Try finding a compatible ASIC!
@@dagon_hydrA what format do u want? did not say it was not special did i? said it does not matter. current ones use so little energy that their sales point on energy use is as futile as resistance to the borg ;)
Love it , when does it come to Walmart? 😅
