It’s crazy how I remember watching tons of videos about graphene back in 2008/2011 and the main issue with it was the mass production of it, now it looks like that’s been kinda solve, it will be amazing to see the actual implementation of the material truly from now on.
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.
I remember reading about Graphene when it was first announced and thinking about the possibilities it opened up. 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! ;)
Because they give the best and most advanced applications to the military first. They're keeping this technology partially hidden from the general public.
Honestly, why not... LOL if I was running a successful business that was organically drawing in press interest, I'd absolutely tell them to wear their best or give them new ones... best foot forward and all... if they wore the perfectly clean but stained daily clothes on TV, few would take them as seriously
To be fair, a lot of the shots in this piece are in small chip fabs. While they may not necessarily need to be clean rooms at the scale they're working at, actual researchers working in these will wear lab coats with fibers engineered to shed less and not offgas as much.

A lighter diaphragm would greatly increase this. and its higher conductivity/gram could further decrease the mass of the voice coil. dynamic speaker technology could greatly benefit from this.

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

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...

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
The same thing that happened with plastic is happening with graphine. Everyone was skeptical until it took over. Hopefully we have ways to get rid of the stuff when we throw it out eventually for whatever reason.
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.

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.
I met someone who worked on a company that installed MRI machines in hospitals. He said the main cost is a refrigerator the size of a small car and pumping a chemical around the scanner to keep it at a low temperature. And a lot of insulation to stop warm air getting into the scanner. I thought Graphene would solve that by a higher temperature super conductor.
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.

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.

They aren't using these hall effect sensors in joysticks they cost over $1000 per sensor. They use regular silicon sensors in joysticks that cost fractions of a penny.
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.

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.
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.
Hmmm can't wait for the first phone with graphene ARM processor that lasts a week on a charge, and graphene photosensors that can take perfect pictures. But the big step will be, data centers that can be passively cooled, saving all that energy for other important things in life.
We have already accepted the current energy use. Rather than reduce energy use, they'll more likely scale up performance to match the current energy usage while serving juicier ads to you at your most vulnerable times. That's the true meaning of innovation 😎 I'm partly joking of course. But only partly. Lots and lots of incentives point towards other outcomes than reduced power use, unfortunately. Apple make their devices thinner and lighter as major selling points when they could instead have fit a larger battery to get longer run time. Same thing happens with absolute performance numbers vs power consumption. Big performance number good, long battery life secondary!
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.
could grahine operate on light, rather than electricity ? so the power source for chip is particular wave length ? A processor with no exteral electricy source
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!
So is the main iteration of graphene with electronics to just replace pcb? It seems its use is nothing more than a wafer for copper traces. How is graphene going to improve upon lithographic transistors other than to offer a lighter material for smd parts. If that’s the case I’d rather see it implemented as filament for smaller leds.
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.
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.
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
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.
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 ;)
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
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.😄)
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.
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.
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 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
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.
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
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.
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.
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
Graphene plus nuclear battery, has some very exciting electronic applications, would love a watch that never needs charging, a childs toy helicopter drone that never needs to land, a games console orders of magnetitude faster. Hall effect sensors are used in some game controllers not sure if they're graphene though. Go science!
18:30 What a crock. There hasn't been a breakthrough in lithium batteries since the late 1980s. The only improvements have been marginal. The lowered cost was largely due to making them in China.

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
Hmmm can't wait for the first phone with graphene ARM processor that lasts a week on a charge, and graphene photosensors that can take perfect pictures.
But the big step will be, data centers that can be passively cooled, saving all that energy for other important things in life.
We have already accepted the current energy use. Rather than reduce energy use, they'll more likely scale up performance to match the current energy usage while serving juicier ads to you at your most vulnerable times. That's the true meaning of innovation 😎
I'm partly joking of course. But only partly.
Lots and lots of incentives point towards other outcomes than reduced power use, unfortunately. Apple make their devices thinner and lighter as major selling points when they could instead have fit a larger battery to get longer run time. Same thing happens with absolute performance numbers vs power consumption. Big performance number good, long battery life secondary!
Has there been any research on what graphene does when ending up in landfill/incinerator/nature? any risks?
Now I know how a hall effect joystick works and how is made do why is so precise and expansive.
Well it’s about time. Thanks for the update.
and how much energy do we need to make graphene compared to how much energy will it save if its in every pc?
There's a claim by Universal Matter that one ton of graphene may cost 100 dollars in electricity with the flash method.
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.
id like to buy a hall sensor, love to see the resolution and if it could improve an idea i have
you guys should maybe try to normalize the volume levels of your videos
could grahine operate on light, rather than electricity ? so the power source for chip is particular wave length ? A processor with no exteral electricy source
Cool, nice to see graphene take off . . . @ 14:24 pizza bag keeps it oven fresh for days + future oven
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!
How did she miss the most common use for hall sensors there used in brushless motors
So is the main iteration of graphene with electronics to just replace pcb? It seems its use is nothing more than a wafer for copper traces. How is graphene going to improve upon lithographic transistors other than to offer a lighter material for smd parts. If that’s the case I’d rather see it implemented as filament for smaller leds.
That sepsis device, is incredible
Amazing. Nobody trusted graphene until very recently so its good to see actual research being done with trust
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.
Very informative video, but why those annoying background sound effects?
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.
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
What devices are running on this so far?
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.
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 :)
‘1000x less’.
Is this a meaningful statement [when not comparing to a previous reduction]?
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.
Great questions, excellent production.
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 ;)
Can graphene stop metals moving at extremely high velocities? , it is super strong, also can grapheme store energy?
Very Interested in this topic.😉🤔
"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.
Wish I could have heard what they were saying above that row in the background
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
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.😄)
Exciting new technologies!
Some of the component packaging is 35 years old.
It is only with the heart that one can see rightly, what is essential is invisible to the eye.
Love it , when does it come to Walmart? 😅
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.
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.
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.
Graphene being a 2D material means that its volume doesn't follow the same square cube law for volume, right?
Love how the non descript medical use is smoothed over
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
We're still too busy putting it on tape and looking at it under a microscope for the cameras.
Great questions, great info, great vd
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
The music / noise only detracts from the message. Provide a way to turn it off
Thankyou
I wonder what it costs to manufacture these 2 inch graphite circles. This is potentially huge, if it can be done affordably.
Just a stupid question, if it works 2d, why not make a 3d version, it could be stronger, but “bigger”, and more reliable to grow/build.
Space elevator plausible now?
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.
I now love the color blue.😊
That’s one exemplary professor , wearing his eye protection 🥽 at all times
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’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
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.
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.
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
Graphene plus nuclear battery, has some very exciting electronic applications, would love a watch that never needs charging, a childs toy helicopter drone that never needs to land, a games console orders of magnetitude faster. Hall effect sensors are used in some game controllers not sure if they're graphene though. Go science!
18:30 What a crock. There hasn't been a breakthrough in lithium batteries since the late 1980s. The only improvements have been marginal. The lowered cost was largely due to making them in China.
The discs are great, but there's a technology that allows graphene deposition along a long ribbon.
Is graphene the haskell of manufacturing materials? Theoretically useful but destined to only shown in white papers?
Can graphene be the next Teflon? (Besides food applications, that sounds like a terrible idea)
