- A new process introduced in Nature by the Rice University lab of chemist James Tour can turn bulk quantities of just about any carbon source into valuable graphene flakes. The process is quick and cheap; Tour said the "flash graphene" technique can convert a ton of coal, food waste or plastic into graphene for about $100 in electricity costs.

You guys cracked it, mass production! Everything's about to change. Excellent work!
Nahh we haven't find a way to mass produce graphene in a 2d structure that's the real game changer. That's the type of graphene we can put in anything.
@@leonesperanza3672 Exactly. That process only creates nanometer-sized products that aren't yet applicable to most usages. Best that version of graphene made from that is for stronger cement, high-density batteries, faster charging, and a few more. The 2D is far more usable in many applications like computers, nanotech, robotics, medicine, etc...
YES ,that's why my batteries now last 50 years . Oh wait a minute , no they dont . That will be when all the oil has gone .
@@irish-medi-weed-grower5240 This is year old science dude, it doesn't turn into magical consumer products overnight. Expect it in another 7-10.
@@TrackZero Graphene as an isolated product is over 16 years old bro . I remember reading a piece in the dailies about the two guys who discovered it getting a Nobel prize. The headlines where something along the lines of "5-10years and we will have batteries that will last a lifetime ." Now that was about 11 years ago . Take my modest word for it bro , this is more about oil than graphene.
NightHawkInLight just did a video on doing this at home. This process is amazing in it's effectiveness and simplicity.
Good job, fruits of research always worth a lot and change the world for better
This is incredible!
okay, so I converted/converting my sailboat to an electric sailboat. I will be adding some amount of capacitors for burst speed (to try to outrun rouge waves) and I feel I could dual-purpose the bank of capacitors for Diy flash graphene. maybe use the motor controller to control the timing. I would like to add it to the epoxy resin as I rebuild and repair the boat.
I really really hope this lives up to the promise.
Promise of $$$$$$ maybe
@@mpirron1
More money means further advancements and an incentive to improve.
@@bighands69 nope, In this case James Tour is gatekeeping for those that Insist themselves entitled over natural law. He's got it all wrapped up In IP Law NDAs, patents trademarks for likely another dozen years or more. Shuffeling among private business intrests incorporated in Canada. Under Crown and City of London Trust Law protection. It's criminal that some things hold more value buried than in the light.
@@mpirron1
Patents are the only way that research can be protected and that the ownership can clearly be established.
Otherwise there would be no research and development.
@@bighands69 bullshit, they didn't have patents and bronze still got created, they protect greed
guys! do you know graphene has the highest thermal conductivity?!?!?
you can passively heat the house!)
it is enough to paint a couple of barrels of water (heat accumulators) with graphene paint
the sun will heat the graphene to a high temperature in 10 minutes (in winter), and this is very cool
because it is at least environmentally friendly
Thermal conductivity (W·m−1·K−1) 4500 - 5500
!!!
OMG Duy Luong, this will make History! You will get the Nobel Prize.
can we do this or is it copy righted
is it free for all innovation
sir , so we can implement this method on e waste plastic which is separated from other components and make graphene yea? Also can any person copy or study this method and start an e waste recycling startup(eg: me).
Can this process be done by using concentrated sunlight heat ?
There is a better path to mass production. I calculated that a 20m radius sphere that is mirrored on the bottom half would reflect enough sunlight to the focal point to heat several kg of rubber (any carbon source would work though) per second to the same temperatures as your flash process. This is assuming a 75% theoretical efficiency (1kw/m2-25%). Since it is a sphere you can pump it down to a vacuum and spray melted/liquid feedstock through the focal point and into a catch pipe. The bottom of the catch pipe can have a double gate to allow continuous removal of graphene.
Another option is to use a mirrored tube, which allows for lower density/slower heating feed stock to be brought to temperature over a longer time. This requires a much larger diameter though because the reflective area is reduced greatly.
This process would be sun powered, so there is very little cost once the sphere is built. Glass is cheap and so is a first surface silver mirror treatment. By adjusting the shape of the sphere slightly you can widen the focal point to account for the volume of the feed stock. This is needed because a perfect parabola would focus too much energy to a small point.
I would assume the flash process probably has a greater efficiency at a control level. The question for this flash process is how scalable is it.
Can lightening be used in some way...?
The graphene gained with this method comes out in granules? Like powder? What would cause that substance to bind with itself, how can that be induced so that it can be molded with the help of a cymascope?
It's at this point that Duy Luong's student visa isn't renewed and James Tour takes all the credit for his discovery.
He has openly admitted that his team does this. He comes up with the general chemical processes and they fine tune and develop new methods.
It stands to reason that James Tour gets most of the credit by being in charge of the whole research process and creates the space for the students to do their work.
Gays you doing great work but is ac capacitor is used
amazing discovery! Could welding machines be turned into production units like this? Just a thought.
Very likely with some retooling and warranty voiding.
You only need around 7 kilojoules per gram and I don't see any requirements for precision tools other than carbon purity of the materials used.
NightHawkInLight just did this. Check out his video.
@@Scott_C going to break his precious patents.
@@mpirron1 lol
The winds and currents of SE Asia drive all the plastic/rubber thrown into the sea, in SE Asia, into the Gulf of Carpentaria. Cape York Peninsula enjoys huge solar energy resources. Combine the two ... and anything's possible!
What we will more than likely see in the future is mining of plastics and other materials from dumps. And probably a new industry of plastic harvesting from the oceans.
Most of the plastics we use will probably get recycled in some sort of organic chemistry industry.
Rice husk agriculture convert into graphene is possible ?
please tell me fg dissolves in ordinary water?

I've gotta ask -- Could you could put rice in there?
Anything that is made of carbon can be put in there
yes
Hello! Is it Carbon? A: Yes!
I think people missed your joke...since it is rice university... =)
@@TheVinceVoice no they didn't, they just answered the question.
"Rice Lab" fits it perfect .... lol
How easily can you scale this up?
Sky Hiker 9, rather than 'how easily', 'how soon', and, 'at what cost/investment' seem more important. Clearly the components used in the vid are available in commercial sizes, and larger sizes can be fabricated. However, the closing statement of electricity cost of $100 to convert a ton of coal begs for explanation.
Sean Flanagan I disagree. Scalability is what keeps graphene in the lab.
@@skyhiker9669 there's a graphene powerbank you can buy now, name "Real Graphene"
@@seanflanagan2441 As per your last sentence: $100 is the cost of one ton. of coal, per James Tour's estimate. It's not the electricity cost (which I think is unknown at this point).
Anyway, I read (link below) the current cost of graphene is $67,000 to $200,000 per ton, so the electricity cost should not be an issue.

How can i contact you?
lets see you do this with pressurized gas? co2 or co. use the coal to power a plant, use the output and exhaust for graphene.
Coal plant produces ash and suit the gases could be used for other processes. So it could be a two staged process of ash and gas.
Now graphene is only eternally 14 years away!
As long as he can keep renewing his patents nobody will ever see it
Graphene is already being used industrially and what is happening now is new and more improved production methods.
anyone guesses on the gas they isolated it in? or why it was in a tube?
The tube probably is a control mechanism.
This is interesting for sure but I'm not convinced of the applicable nature of it. Powdered graphene is great for research. But, how well is the thickness controlled? I sure there's a bit of randomness to it but is there a specific method for controlling that? Otherwise, it's not much different than reorganized graphite.
You can get hydrogen too, it doesn't matter though we're talking about eliminating plastic waste and most of what goes into landfills, how much money, carbon, and living things might that save? Maybe no one actually wants to save lives or reduce our carbon footprint for free.
@@mpirron1 There's no reason to take a condescending stance where you think you know more than I do or that I can't appreciate the research. I'm literally a 4th year Physics PhD who studies graphene through CVD production. My questions, in terms of condensed matter, are valid.
@@JohnFerrier I didn't say I knew more than anyone. If I come off as condescending, it's because I am straight up accusing him of dragging his feet purpose fully and hiding behind IP Law as he is doing it. I am saying he doesn't care to address any question or concern you or anybody else has because he is actively suppressing his own lab's technology. Sometimes it pays more that way ya know?
@@JohnFerrier maybe you'll be the kind of scientist like Nikola Tesla. But most scientists, no matter how brilliant, are much more like Edison.
I have a doubt.. If you put pure black carbon inside the quartz tube and give it one discharge, how much of this carbon is turned into graphene? Thanks! Great work!!
NightHawkInLight just made a video explaining the process a little better. Check him out.
@@Scott_C Really Thanks!!
1:28 look's like sun shine actually grapheshine :o
Could the graphine particles used for the concrete pose a risk similar to asbestos?
Nature already has particles and they would not be allowing the graphene to freely escape. Graphene like structures already are present in nature all around us.
The Romans two thousand years ago were using volcanic ash in their concrete process to make structures that still stand today. This would be a much more advanced process that could be giving us roman standard concrete today.
Are they starting to selling online? or is it just the announcement
They are licensing the technology out.
Is it posible and easy enough to replicate this at home?
NightHawkInLight just did it in his garage/studio. So, yes.
@@Scott_C Im gona do this as my high school graduation work . I study as an electrical engineer.
Wow
Could I purchase a small amount of this from you?! - a nerdy Canadian
How much electricity would it take to convert 1 ton of coal into how much graphene?
U need a fusion reactor for that :)
They claim$100 dollar in electrical power.
Do you need a ton? Or just enough for your needs? Nighthawk channel and Robert Murray Smith channel do it at home. Small batches.
Build water welder for power needs.
The key in this would be to use the coal to generate electricity and then use that ash as a raw material for the process.
scrubbing technology as a filtration process is getting so efficient that nearly all of the waste from coal is captured and with further engineering it probably could end up at extremely high 99.9% efficiency.
So a coal energy plant and graphene plant could work together. And excess energy could be put on the grid or used in surrounding industrial processes.
Succesfull
In which applications did your type of graphene prove its value?
Cement industry
@@virtualprogrammer2057 In the past, cements with organic ingredients used to fall apart after a few years, much faster than the inorganic cements.
@@HarryKhan007 Tour said that this graphene will strengthen cement by 30%.
@@virtualprogrammer2057 It will take a few years to assess the long term stability of this new composite material.
@@virtualprogrammer2057 OK, but a cubic cm production of concrete is not impressive. What is this 30% stronger material going to cost - per cubic meter - compared to traditional concretes?
Commercialization is important
lol did the teacher want some credit
He is the professor and chemist who directs the research from the beginning an has put decades of work into it.
SO yes he gets to take some credit for it.
@@bighands69 Fair enough
Where is the funding?!? GOGOGO
Waste-to-graphene Method: Flash Graphene Rocks Strategy for Plastic Wast
Waste-to-graphene method gets an update
Rice University researchers have modified an electrical technique to convert plastic waste into turbostratic graphene. The updated method involves using a different sequence of electrical pulses to increase the quality of the graphene, which can be used to enhance concrete, composites and other materials.

Are you planning to develop this method for mass production??
When you can use garbage as a source, why on earth would you mention the coal industry is really hurting so we could save it by using coal? Why would you use a mined mattress instead of a waste product?
So...this is Mr. Fusion?
Yes.
One of many.

selam jsvsjsdhs
We cut our hair, cut our nails, or stool as wastes... Can it be converted to graphene? it is still carbon. It's a legit question.
Yes it is a legitimate process to consider. What they probably would do is break down the waste into a solid material that can then be used in a process like that.
There are other chemistry methods that can be used as well for dealing with the waste.
im waiting for very low price for it)
want to build my new house
now im collect graphite from batteries)))))
hello from russia
You call 2 cubic cm a bulk production?
How about 2 cubic meters?
I did not see your graphene float on magnets, to corroborate the quality.
Why did you construct a bank of capacitors, instead of using a welding inverter?
You are using a highly purified carbon as a basis,
so why not stuff some of the beloved garbage into the tube?
Highly purified carbon like carbon black is used just to simplify this "flash" process. In order to get to the stage of carbon black, there are specified processes to deal with that....Even if they propose to use coal, you still need to get that "purified" too...
Is graphene toxic to the lungs tho?
Nope, it's just carbon. You're based on it, ... unless you're a computer... .
@@Scott_C Depends on the size, carbon particulate matter is just carbon too, but kills around ~
who's that girl behind??
Token girl lol... The left will claim she invented this process 20 years from now... 🤣
Is part of the research team.
@@snaz27
As funny as that is and probably true in what the modern media does that girl is probably an excellent chemist and does lots of hard work on the team.
Unsaid is that they'll get filthy stinken rich from this.
That is a great thing if they do.
I'm only here because of Ian crossland
In 2030 we will be making graphene out of poop
Is this patented?
So much that even asking that can probably get you sued!
The funny thing about patents is any change to the process which has a benefit renders the original patent toothless, and the definition of benefit is wide.
Patents are what make the modern world so spectacular as the person who develops the concept gets rewarded.
Hence why the research takes place.
Yeah! Now we can make a BUNCH of graphene FLAKES!..... We want sheets of the stuff guys. (I know the flakes are great as an additive to other things (concrete, plastic) I do not care.
Why does youtube's spell checker still not recognize the word "graphene?" that's pathetic.
That girl 👧 in the left is beautiful though. 😍😜
What did he say about girl scout cookies is he talking about weed
He is talking about the fact a cookie which is made out of carbon can be used as a raw material for the process.
Soo, there's dead roches in girl guide cookies?
We have garbage piling up on our planet and you want to use this on COAL??
It's a start...
lol. That's what I thought!
Maybe coal can yield more graphene than trash? Great stuff here. Hopefully goodbye Lithium.
In other vids about this, they actively state that garbage will be a huge source of carbon for this.
www.sciencenewsforstudents.org/article/converting-trash-to-valuable-graphene-in-a-flash, they used coal as a main example. read this.
lol why would you use coal when there's a million other cheaper forms of carbon.
Investors
Purity of carbon content. With an electrical setup such as this you can only get so many shots per day, the more carbon pure the base ingredient the more graphene will be produced by this method in a given time frame. Coal is readily available and cheap, plus each ton that gets converted to graphene will be one less ton that could get burned. That is a win win. Nylon is also made out of coal.
