- In this video we explore the recently discovered process for creating flash graphene: the first economical method to make high quality turbostratic graphene in bulk. Using this method it's possible to convert nearly any carbon source (recycled materials, coal, carbon black, etc.) directly into graphene.
This was discovered by a graduate student, Duy Loung of Rice labs, as detailed in this article (videos of the process are contained within): news.rice.edu/2...
The first Flash Graphene article as published in Nature: www.nature.com...

As a result of these discoveries Dr. James Tour (the lead chemist at Rice labs), and his team have founded the company Universal Matter Inc. in their endeavor to scale and automate the flash graphene process for commercial production. In only a few months they have multiplied their methods to produce 6 grams with each 30-100ms discharge of 48 high voltage capacitors, in a scalable model that may produce as much as 1 ton per day.

Thank you Ben for the great demonstration. These type of DIY demonstration was my inspiration for the discovery. Keep up good work! By the way, you might want to pretreat the coffee at multiple lower voltage treatments first to remove the organic volatile before the real flash.
great job
you are going to create a public company that we can invest in right?

First, off I wanna say great video. But I looked up the paper and have some huge concerns. I've actually done a lot of work with graphene and what they're demonstrating is... odd. And frankly seems a bit cherry picked. Things that are interesting: ease of dispersability, and the seeming strength increase when added to stuff. Things I find concerning: those electron microscope pictures and some key notes.
When you look at the microscope images, and then their simulations, what they've made isn't really graphene per say, and especially not graphene in an ideal form. Graphene at it's strongest are big flat sheet. What they made are weird onion shaped chunks. At least, in the images they chose to show. In that mixture there's very very likely to be various other carbon materials; nanotubes, other fullerenes, carbon onions, and random amorphous debris. They did no purification to remove any of that stuff and when mixed into a solution, it'll all just look black. Only a few fullerenes have a distinct color in solution. So mixing it with a solvent will look like you've made a graphene solution when in reality it's just shmoo floating around. In fact, when you look at the cuvettes of "graphene solution", they look more than 50% full of sediment, with only a very small amount of liquid on top.
This could explain the strength increase, but also the error bars on that test are fricken massive, their sample size is 3, and they use a weird surfactant to dissolve the "graphene" which they have no negative control to compare to. Like there's no concrete sample with just the surfactant and no graphene. So either the mismash of components is what's making it strong, or the surfactant is, or they just didn't run the test enough times, or any of 100 other reasons that sample looked stronger.
ALSO, they show a side by side comparison of "commercial graphene" vs FG. Why... is the commercial sample clear? Like not just clear, but with no sediment at the bottom? To me that screams "one of these vials just has water in it because we didn't add anything to it". Because any commercial sample should dissolve at least a little, and the rest would sink to the bottom. Unless they're showing supernatant? I dunno, very weird. Also the way they're solubilizing things is odd. They're using this weird surfactant pluronic 127 which I'd never heard of but I suspect makes things appear a lot more "soluable" or at least dispersable than they really are.
Further, saying "graphite is the 3d form" isn't really accurate. Graphene are big 2d sheets of carbon. Graphite is simple those sheets stacked up. If anything, the stuff they made is the "3d" form because it's a jumbled mess of interconnected layers and closer to amorphous carbon. This will make it utterly useless at being turned into fibers as you won't get the large sheets forming a liquid crystal in solution which is required for that. Also they don't talk about the oxygen content of the "graphene". If what they made was highly oxidized, then that alone explain why it's soluable in water. Graphene oxide is already water soluable. I've got a bottle of it. So if that's what they made, then it explains some of it's weirder properties.
All in all, none of this is NOT a criticism of your video. The video was great. But their paper to me, was super super sloppy and leaves a lot of unanswered questions. Especially when it comes to things like graphene, there's a lot of really crappy research that turns out to be useless on further study.
Soluable.
Thanks for your comments! You certainly have way more depth of knowledge in this area than I do. I'll be playing with the process more myself and see what comes of it. Most of the graphene research I've looked at is really lacking in side by side performance comparisons of various other graphenes and graphites.
And the paper was published back in January, i would assume companies would have started (or talked about starting) any form of mass production lines using this process by now. But nope, no word about it at all. So im also calling bs
I think at least this is a good start....
@@Nighthawkinlight Ya for sure, give it a go. I'm excited to see your results. But ya this is what I mean. Most graphene papers... suck.
Also, making graphene can literally be done in a blender or ultrasonic bath at many-gram scale. A solution of tannic acid (green tea works as a lazy substitute) is mixed with a bit of graphite powder, then you just ultrasound (or blend) the hell out of it for 2-4 hours. A mixture of acetone and water also works but I don't remember the exact ratio and that's obvious more sensitive to heat because the acetone will evap off.
Or you can oxidize graphite first using the Tour method, then ultrasound it briefly to get a stable solution of graphene oxide in water. Lots of way to do this that'll produce big sheets of graphene and not weird clumpies.
You guys remember when I was making videos about paper crossbows?
Pepperidge Farm remembers.
yea.. also.. graphene crossbow?
you came a long way brother , keep it up !
That was bait to get us hooked into the real stuff
Of course. That's around the time when I subscribed!
I wish you had been my neighbor when I was a kid! My dad didn't have time nor was interested in my questions as a kid. I saved up money from walking beans and mowing grass for a high quality microscope, and then put together a seriously awesome chemistry set. I successfully made nitroglycerin, built a smelter and refined gun range lead, made ingots of aluminum cans and various junk metals found around the neighborhood, I made hydrogen and oxygen for various burning and oxidation experiments, made chemical fertilizer for my garden and never blew my family's basement! Moved on to making various solar concentrators, cookers, burners and such. Got into magnetism, electronics and radio wave theory. My point is information presented in the way you present it was not available back then to but a very few lucky kids with overachiever dad's. Thank you for doing the teaching you are doing! You may well inspire and help some young inquiring minds to further explore areas of research and be the genesis of new technologies! Subscribed and liked! Thank you again, well done!!!
wao
great struggle for knowledge i appreciate. And would love to have that passion for my goals.

“Oh yeah, it’s all coming together”
I am more impressed by Rice Labs sharing this information than them discovering it.
A bit late, but anyway. Haha good one. They have patent (2019) out,... so is available to public. If they didn't have a patent,.... then you will not get any info out from RIce 😁😁
Apparently they omitted a couple things, i watched another channel (tech ingredients) follow the directions much more closely and I recall they had to figure a couple things out on their own that apparently wasn't in the paper, heh. Really great video btw if interested.
Uh oh, graphene optimism. You really painted that target on your back brightly with this one. ;)
My fingers may fall off with how tightly I have them crossed...But I am optimistic!
@@Nighthawkinlight I have the highest of hopes, however I have learned over the years that graphene is the sweet spot for crushing them expertly. This could also be something that could help fuel a surge in renewable energy now that I think about it, if graphene becomes cheap enough that electricity costs are what affects the profit margins significantly, the industrial complex that would surely form around this material would surely push us forward in the direction of cheap renewable energy. Awe man, now I'm excited. What have you done?!
@@robotslug "Renewable" energy is the dumbest possible application for this. Come on.
@@websterri I mean, expanding and hardening our energy infrastructure, while reducing cost and at the same time reducing our destruction and poisoning of the earth to a dull roar at the same time doesn't seem dumb at all. Not to mention I only brought it up as a supplemental benefit to the expansion of a graphene industry. I never brought it up as an "application" of graphene tech, but if I had then I would absolutely support it, as the transition to renewable energy is one of the most important hurdles humanity faces currently. Energy storage and efficiency of production could be greatly benefitted by graphene.
@nighthawkinlight, I sincerely hope that you're successful in commercialising this new technique. I also hope that you'll continue to educate us even when you don't need youtube money
That capacitor bank looks terrifying.

Ben's a Patron on this channel, isn't he?
This channel (and I've been saying this for years) is an ever expanding repertoire of knowledge. I hope yt is still a thing in 20 years so I can show my kids all these amazing content creators.
In your reading, did you find any alternatives to carbon for producing a substance with similar properties? I mean, there are tons of other hexagonal atomic configurations. If we're so hung up on using carbon every time, we might be overlooking a (probably still difficult) possibility that could at least work until we crack the case. It's just a logical precept that if everyone's stuck in a doorway, maybe it's prudent to go around.
Sorry to offer up lateral thinking as though it were an original idea. lol.
I once worked with an engineer who believed it probable that life on other planets would be boron-based. Garbage speculation if you ask me, but who knows? Simple geometries can give rise to some incredibly divergent emergent properties. Either case, congratulations on becoming one of the bright spots here on UA-cam; using this medium for furthering the experimental cusp is some seriously solid content. Mad respect, and keep tinkering ;)
I think I've read about silicon as an alternate for similar structures, but I haven't looked into it much. If i get the setup going properly I might try throwing some other things in the tube and see what comes out. Not a bad idea!
monolayer molybdenum disulfide is supposed to be promising for electronics applications
Heard of boron-nitride (iirc) that has similar strength but massively reduced brittleness compared to graphene.
Graphene would be the ultimate, carbon bonds are the strongest because they have 4 electrons and need 4 more to fulfill the rule of octets. With 4 bonds it makes it optimum. So think of diamond, thats pure carbon, which then decomposes to graphite, graphene would be like having a superbendable flat version of diamond. So diamonds can be broken because of how they are but they are hard, but adding it bendability means that any force applied would disperse over the surface. Image graphene body armor like multiple layers thick. It would be way better then even black widow spider silk.
@@doodman3502 The question posed related to carbon _alternatives._ Remember that analogy about being stuck in a doorway? I had asked about another way out of the burning building, but you're still explaining to me the ways in which the doorway is preferable.
Sorry to jump on you over this, but consider: such responses are thought-stoppers. Ask a forum how to avoid buying an 'x' by instead using a 'y' and (nine out of ten times) they'll love to tell you about how 'x' works best; such conformity is antithetical to creativity, no matter how spot-on a given re-statement of the ideal solution is.
So~ thanks for adding the peripherally-related explanation, but you didn't RESPOND TO THE QUESTION.
Saw that giant capacitor bank (a major flex) and clicked immediately. In another era, you'd be the top show on PBS. Amazing production value of consistently amazing videos.
Excellent - thanks, Ben

yeah i know... ffs
You know you're going to have to do a batch of flash graphine infused starlite now right?
@ニンコー it is thermally conductive but thermally resistant and thermal shock resistant (thermally tough), it might make a good cover layer on top of the starlite maybe? It's a for fun experiment.
@ニンコー I think it would actually be fine. Since the flakes would be mixed into more or less homogenously, what you'd probably end up seeing is heat that more quickly penetrates deeper initially (as the graphene helps transmit the heat deeper into the material), but then the added strength from the graphene in the carbon foam that is produced should help this foam layer last longer. End result would be a more durable starlite that can take a beating for longer, despite initially generating foam faster.
I’d love to see a part 2 where he uses the capacitor bank and tests blocks of concrete to show the difference
The moment i saw the huge capacitor bank i just thought to myself: coil guns....
For your next video you sould make a coil gun it will be so awesome!
even better, a rail gun. :)
@@MrTubeuser12 you've got that around the wrong way. coil guns are better than rail guns. they can achieve much higher velocities

This is the sort of videos that are REALLY the reason I paid my Internet. Mind you, since an engineering viewpoint, you could build a DIY setup at home and charge your capacitor rack with solar or wind. Using your favorite carbon source and flashing it, then shipping it by the crate to some refining facility for post-processing into graphene, once the primary process is already tuned up.
If this production scheme doesn't get the costs lower, then I don't know what would do it.
Thanks for this, buddy.
Fabulous!

Thank you.
Amazing video!! :)
as per usual 😉
Wooooooahhhhhh thank you! Thank you! Thank you!
Off to the drawing board!
This will combo with the geet plasma refinery I made!
Now I can direct the excess carbon BEFORE the main chamber gaining the graphine before it hits the plasma and dematerializes. This allows the engine to operate as a generator and production machine! And I'm currently running it off just air. For 17 months now it's never turned off once, uses air as fuel, and produces more oxygen as waste than three forests annually. It's been an un-upgradable system for too long. Extra money printer/construction resource refinery! Here I come 😁!
To those wondering, no the geet normally doesn't run off air. I had to work three years to tune it to intake enough larger gaseous molecules to break into workable sub elements, then make whatever fuel I was aiming for, then use the reactor to waste only oxygen molecules while returning anything else for plasma continuation. The free pdf anyone can download runs on nearly any liquid. I tuned mine to run on any gaseous mix.
Thank you for introducing me to geet - after researching just a bit, it is highly interesting - I'm only confused as to how it's so little known that I haven't heard of it until now.
Where could one find your PDF? I'd love to read it.

Love your videos. Clear, precise and free of annoying music.
I love your comment on the graduate student that made this possible. Professors at universities might be great at teaching something but they are most certainly not hands on usually. This is a case of the student being more resourceful than the teacher for sure.
That’s amazing! I could see this process becoming automated generating tons of material.
You, Sir, are a freaking genius!
I admire your knowledge, I admire the way you think and I admire that you can build those things with mostly cheap components.

I’ve been expanding my knowledge of many things in many ways lately and you explain the most complex stuff very easily to understand and I wasn’t planning on learning the content of the first video that I saw of yours, but I gave it a few seconds and low and behold I was learning serious major stuff in less than one minute. You are Awesome! THANK YOU!
It took me until the age of 40, to finally get a science teacher I can learn from...
I used to volunteer at a science museum; we had a teacher conference where a NASA rep have us the latest on upcoming stuff. He talked for a considerable length about how graphene was going to revolutionize everything from plumbing to skyscrapers. This was back in 1994 or so. I look at it as a slightly more believable product than fusion at this point... so maybe, just maybe... you have me changing my mind
The most exciting development I've heard in a long time!
Great video. I've worked in biomedical and induction industries for years and have followed graphene for some time. It is great that we are making big strides toward making it affordable to produce. Than you.
Did my chemistry final self directed lab on Flash Graphene!! This is super cool!!
Robert Murray smith showed us how to make graphene a few years ago using a cd burner in a computer I believe it was. I am not sure how his final results compare to this or any of the other methods as all of you guys are now way over my head. Keep up the good work.
Just google (carbon coater work principle) and you will find something 90% similar to this. The only addition in this paper is they used more capacitors so the current was ultra high and the carbon exploded very much to make flakes and loads of other things that very likely not graphene because it is simply chaotic process! What made the buzz here is the name of the professor behind it not the novelty of the actual work. Sorry!
OMG YOU ARE BACK i remember watching your video when i was 12 and its been 5 years. Awesome dude

Remember it mentioned for the first time probably 10 years ago. The miracle material that is going to change everything but i see it hasnt left the labs for the most part. Still working out production means. Im sure its gonna be worth it.
A SCR is the best way to switch a capacitor bank. In your case you would need two: One for the main discharge and one for a emptying discharge since SCR's cannot be turned back off as long as a voltage is present. So use a big SCR for your working discharge and a second smaller one do dissipate the rest of the energy through some halogen lamps.
One thing I misremembered: SCR's have a holding *Current* , not a Voltage.
You could start off with a couple of these:
TYN80W-1600TQ
To trigger them you can just look up SCR Trigger circuit. Typically a couple of AA's should be enough. If one isn't sufficient just add another one in parallel.
YOU ARE THE BEST SO IS RICE LABS!
Those capacitors are scary looking.
Really nice video, Canatu Oy in Finland do quite well. -I was even going to say it's a process like spot welding and then you turned on a welding box even though I know you it's not proper and that a cap bank is needed. Really cool stuff dude, keep posting videos :D
It's cool to see how simply this can be done. If you haven't, I suggest Tech Ingredients' video on flash graphene, they go extremely in depth, and do some structural integrity testing as well. (They use carbon black and use a vacuum chamber for better efficiency). 0.6% graphene effectively quadruples the bend resistance of an acrylic tube filled with epoxy. Fun stuff.
Hi Nighthawk. would you please make the additional information that you put up on the screen, last a little bit longer? It disappears before I have a chance to finish it. You make great videos. Very informative & entertaining. Thank you for sharing your knowledge.

I hope this is true and we can start to make it with human and food waste, this would really help lower CO2 in the atmosphere.
We can make some good methane and fertilizer out of that food waste but the graphene would be really good too.
Methane and organic fertilizer would both contribute to CO2, we need a way to store the excess carbon that used to be stored underground in the form of coal and natural gas.

Graphene oxide (GO), an oxidized derivative of graphene, is currently used in biotechnology and medicine for cancer treatment, drug delivery, and cellular imaging. Also, GO is characterized by various physicochemical properties, including nanoscale size, high surface area, and electrical charge.
Cool, now we can start extracting C02 from the atmosphere and converting it to Graphene .

This channel is gold!
Hey Ben saw an article about a new cheap way to produce graphene, and immediately thought of this video. Look up "High-Quality Graphene Using Boudouard Reaction," researchers claim it's a "garage solution"
Hey Ben, I enjoy seeing you making great stuffs and love the way you explain them so neatly. I wonder can you make some supercapacitors out of those graphene that you just created.
I'm a glass artist. We use carbon graphite hand tools for working with hot and molten glass.
This is interesting!!
I am going to keep a close eye on this channel. I think you are going to solve the mass production of this and revolutionise the battery/energy storage industry for the better. Many thanks Ben.👍
So now I have this and the fireproof material, time to make some badass armor
That’s epic, I’m impressed by the capacitor bank, it looks lethal. I’ve made Graphene using a pencil and sellotape.
You could use a large knife switch to discharge the caps and a fuse to cut it out at around 5ms. You would have to design a new fuse to handle the current for 5ms though there might be a commercial lightning fuse available. You could possibly use a magnet and a few loops of thick copper in the circuit as an electromagnet to push the knife switch open as soon as the current flows, that should provide a quick interrupt.
I am interested in learning more about the two step process first using AC current, then DC. I have been watching videos regarding the Flash process trying to get my head around it, this was very helpful.
This is hilarious. I've been thinking the last few mornings as I through out my coffee grounds how I could use them rather than trash them.
Fkn wow man, always impressed when you display some high level shit like this. The range from fun silly projects to this kinda stuff is refreshing.
Thanks for the info. I have used the electrical method to make graphene.

You know its gonna be a great vid when you see a houmongus capacitor bank only a couple seconds into the vid
They have actually known about this for a long time and only recently chose to release it to the public. This is how they built up the hype for the "future", drive orders and stay ahead of everyone.
That's good food for thought! Happy to hear that you have safety in mind.
石墨烯。 您总是带给科技迷无尽的期待。
Usually I would recommend SCRs for switching such high energies but those devices will run several 1000s of $ for the power rating you need for this capacitor bank (450V at several mF is nothing to sneeze at). The voltage is too low for using a triggered spark gap w/o losing .5 of your energy on the switch. What you could try however is to use the reaction chamber as the switch intself:
Introduce a small gap into the material and use a inductor in series, and one inductor coupled to it (think single pulse transformer) to send a small high voltage spike on the gap. If done right you can dump the entire energy of the CAP bank on your reaction chamber.
Safety precautions:
#1 USE BLEEDER RESISTORS, plural!
#2 attach multiple voltage readouts on you cap bank.
#3 never touch the cap when charged to any voltage other than 0V
#4 test any setup at smaller scale first! Having a charged cap bank sitting on your bench that you cannot discharge because your switch failed is no fun experience.
... these devices are dangerous, treat like unexploded primary explosives.
There's some 900v 500a relays for around $100, which is what they used for the setup at Rice labs.
Great video! This is truly an incredible discovery, and this is the first demonstration ive seen of it. If you were to remove the other impurities, and if they could be refined/reused, i wonder just how much more we can find here!
Dr. James Tour phenominal guy!
Your channel is one of the best.thanks
Graphene is legit dope, I prefer it over Borophene because it has everything I could desire especially for a Supercapacitor System.
Great job I didn't think that anyone besides myself in the backyard Labs or DIY community would be interested in this. You can up with some great information that can help us. The independent researchers and engineers.
i look forward to the video on the cap bank! i love all the science that you do, ever since ive started watching when you made your video on the wood gas generator.
Raman Spectroscopy would be much better than EM to detect and qualitatively analyze the end products. From the Original Paper, the energy supplied was not inordinately high. Of the order of a few hundred Joules, IIRC. Great Explanation of the process! Now put a couple holes in the quartz tube and make this process automated! :).
This is interesting and broken down to a more simple explanation.
Graphene has been making its mark in car products like waxes and coatings.
Now makes me question how much graphene is actually in a "graphene infused wax" etc.
What amount of graphene could be flashed from a 30Lb tire?
Love your videos.
Keep up the great work!
