+CK A Because of mass manufacturing of graphene sucks!! How many years did it take for silicon chips to develop?? Ever thought of that?? Aren't you a college graduate?
Sadly Graphene is brittle. In theory it looks good, but mostly graphene only works as a powder and here is the biggest issue. It doesn't get along with other material, which means, yes, it can't be combined with other to harden the composition. So it's never gonna leave the lab.
Graphene is like plastic. You want plastic socks? Go into your pantry and put grocery bags on your feet, then put your shoes on and walk around for a while. Awaiting your results.
Yes they will get money but as long as people give them money at there own free will and they carry out what they said they were going to do then what is the big deal,everytime someone makes something new should they just give it away for free ?
A Who Snackbar the Pentagon will take tax money to develope it and then give it away to corporations to profit while assuring barriers to copying if natural cost barriers aren't around
SR Productions You will get disappointed... fulrene and CNT were once the most amazing materials discovered and are completely useless! Great properties in microscale, useless in practical applications
yh ik that but it can make better batteries..possibility might be unstable like the note 7 one but it can minimize alot of things and save alot of space to pack more power in devices and give it better durability hopefully if they smart enough to manipulate it
wow I understand physics at a low undergraduate level but this is honestly such an amazing video for people who understand little to nothing about physics. very well spoken and produced video.
Honestly, this is the first good video on graphene that I've come across. When you say "graphene is X times stronger than steel", you actually explain what it means, and you stay away from pie-in-the-sky technologies, and instead scientifically explain what it can do. Well-done.
asian professor: I work at a university curious person: oh which one? asian professor: i work at RICE university *awkward silence ensues* how could they be so mean to asian professors
Basically you could build a 60 mm plate of graphene with the same amount of protection against kinetic energy of 600 mm of armor and with the same weight of a 6mm steel plate
It'd break the heck out of your ribs. It'd replace kevlar but not solid plates. You'd still need something like steel or ceramic to absorb the energy or you might not be full of holes but you'd die of internal bleeding from ruptured tissue and blood vessels from the massive punch in the gut
@@MrWhangdoodles yeah obviously it gotta be composite, but even as composite, the shock would be to big to be absorbed by your body. But the situation would change if you used graphene in a tank: you'd just need a sandwich of 15mm of steel + 100mm of graphene +15mm of steel +some anti spawling material to have a protection equivalent to 1030mm of steel at the weight of a 45mm plate.
hey.. i have seen cutters come out of a mill spindle or parts come out of the chuck in a lathe.. something doing 14k tends to make it around the inside of the machine a few times... you respect this technology when the part hits the window your looking thru dead on.. you realize you still have your head.
It doesn't matter whether it is penetration proof ( most of the material already prevent penetration) , the main question is how much of the kinetic energy is passed through the material to the other side.
somebody say.... *_REAL LIFE CAPTAIN AMERICAS SHIEL?!D_* lol jk, it would make a bit more sense to just make body armour. Although it would be pretty cool to have a shield out of it
Charlie Doing Stuff this metal is so similar to vibranium.it blocks the power too.btw it is cool to make black panther suit out of it it would be so cool
The problem with graphene is that it's a 2D structure! It does not scale! 3D graphene is graphite, and that's weak because very little is holding the graphene sheets together, save for weak Van Der Walls forces.
Actually, the main issue with graphene is making continuous sheets of it. The reason graphite is weak isn't because it's make of sheets stacked on top of each other, it's weak because its made of tiny sheets no larger than a grain of sand wide and full of elemental impurities that break up the structural integrity. If you were to make continuous sheets of atom thick graphene with the length and width of a credit card, you could stack thousands of those sheets on top of evach other as much as you want without losing structural integrity. Unfortunately, we're still struggling at making continuous sheets of graphene without other elements getting mixed in and weakening the end product.
Tbh the real gem would be a non Newtonian fluid graphine mix + graphine armour. Graphine armour would take the impact where as the fluid would harden as the pressure hit it, absorbing more energy at a lighter weight.
Is it a good design though? Would be more efficient to just use a flexible material. Having a Fluid inside your vest is weight as well as the potential for it to leak out for some reason leaving you more exposed.
Scott, I don't see any conceivable way that would work. When non-Newtonian fluids are hardened by pressure, they also become brittle. That might work if you are hitting the body armor with a hammer, but bullets are penetrative, and would simply break through the fluid.
it is a big problem, roads cause a lot of damage not just to peoples pockets by ruining their cars but it also wastes a cities money that could be put to better use
the best thing to use this for is things like wind turbines and solar panels we need solar panels that wont be damaged by the weather and are available to everyone so that people could reduce power usage from outside sources
In a world, where the nation who can sustain a nuke strike is king, graphene, and other defensive research, will be the new oil. If North Korea wanted to randomly send everything it had at the US, we'd currently have a 50/50 success rate of countering about 50 inbound rockets, regardless of their nuclear capabilities, while they were still over the Pacific.
Why do people think this material is super expensive, it is not, huge quantities yeah, everything is too expensive in large quantities, but it is not, search Hummers Modified Method, it is not expensive.
Now it is easily available ! I don't know the source of it for this video. But the production of quality GNP has been achieved for ~ 30 cents per gram !
I really don't like it that this same test is not demonstrated with CNT's... There is amazing kinetic dispersion with CNT's. This feels more like... a downplaying of its properties when it comes to stopping conventional weaponry.
Perhaps, with enough research, graphine could be used to create a small electromagnetic field around space craft to protect against solar radiation. Possibly similar to a farade cage.
I do understand that preparation of graphene for conduction of heat and electricity is rather easy. Just use those thin sticky sheets with graphite dust... My question is how do I obtain/prepare the strong version of it, like the one that can be used for strength demonstrations?
Wait Graphene is only 10X better than steel now? That used to be a much bigger number. What happened? And it's also per weight and since carbon is much less dense, it would take more volume of graphene to = the same penetration proofness as steel. What happened to the whole, you can stand an elephant on a single layer sheet of graphene analogy? I'm sure an elephant can't stand on the equivalent sheet of steel without it tearing.
What i want to ask is if employed on say a satellite how are you able to come up with a thickness or model of what you would need for protection from micro meteorites, is there a velocity or uniform speed that you use or is it based on theory. I would also like to know what happens to graphene when you have a lot of it together does it act the same or does it become reliant on its shape or form.
The sword advances and the shield follows. Same as its always been but "theoretically" and small scale perfectly conducted tests in a perfect environment can't hold a candle against practicality, low cost and a tangible made product. It has to work better, much better and for the same or less manufacturing cost to beat something everyone knows and loves. You came up with the idea, now send it to the engineers and the workers on the factory floor so see if it can actually be done.
There was the punchline: deployed to protect "the war fighter" along with satellites. We'd better start thinking about things other than war fighting or we're goners no matter how smart we are.
Even if you can invent new ways for people to avoid war, politics wants war regardless so they can remain in power. Industries don't like new inventions that changes hand from those in power, there are even people who may have disappeared or 'removed' by those in power for attempting to do so. You could change how humans live, but you can't change human greed.
dra6o0n, in a world where secrets are harder to make by the day, human greed, in my opinion, will forcibly change. It's how humanity works. Over 90% of past humans fucked their cousins.... today it's being weeded out rapidly. Our ancestors were more or less okay with old men fuckin kids.... today, capital punishment linked to child fuckers aren't unheard of. If we can apply order to how humans function sexually within a society, I have little doubt we can apply order to the greed that life burdens itself with. And no, this isn't to say that we've perfected applying moral orders to sexuality, as morals are no more real than opinions, to which we all do differ, but the degree to which we've re-shaped what our ancestors did in the bedroom is quite possibly the largest, questionably baseless, transformation since religious circumcision. And no, this is not to say that fucking siblings or children is chill, but making babies with your 2nd cousin is about as dangerous as having babies with someone from across the planet, while pregnant 15 yr olds are about as dangerous as having a 35 yr old pregnant lady, for baby and mom.
Doesn't take more than 3 years, given how fast technologies is coming by. 2017 and 2018 is likely the years we'll see rapid advancement in space technologies, mainly because everyone knows it's necessary given the amount of crazy climate change we are seeing. Face it, some people are getting a bit unnerved by the unusual changes in the environment (and the threats increasingly imposed by other humans) and nations are now doing a space race to colonize mars.
dra6o0n il I'm not that optimistic, I think we will see this in more like from 2025-2035. I remember back in 2005 they walked about wireless charging, but still w haven't got that far. Yes, we have for example Samsung mobile phones charging wireless, but that requires placing your Samsung device on a charger. So, after 13 years we still don't any advanced form of wireless charging.
There are different types of expectations though. For example, it's common sense for radio wireless charging to be extremely inefficient as you're shooting a cone into a device, with 90% or so of the energy dissipating. Wireless charging has always been about induction, and not radio ionizing which I think you're referring to. And like you said, induction is everywhere from cars to phones now. But graphene is much more practical. And with recent synthesizing techniques just discovered a few months ago, it can be mass produced much easier now.
Probably a small coilgun with their dust-like metal particle put into it, just a series of coils that apply a magnetic force to the metal ball and propel it forward. Obviously done in a vacuum.
I've searched and they used lasers, they put a very thin sheet of gold behind it and shoot it with a laser, the gold vaporizes and propels the microbullet. physicsworld.com/cws/article/news/2014/dec/02/supersonic-bullets-test-graphenes-strength
so this in combination with spider silk amor could basically be a really good sub dermal set of body armour. couple that with traditional armour reinforced (or outright made of graphene as well.) and you'd have really friggin good armour. not to mention sub dermal armour is virtually undetectable, unless under X-rays. (I'm assuming X-rays would pick it up, but you wouldn't really be able to get rid of it, since its already under the skin of the wearer.)
Just because there are conflicting theories doesn't mean it isn't productive. In fact, it's what makes our science and tech function and improve. Conflicting theories, the best ideas clash to form better ones.
What about a space elevator? Could this be used one day to make an elevator to space a possibility? I feel like this feat is a technical issue and not a theoretical issue anymore. And it would revolutionise the world in a big way. It'd be the next "industrial revolution" or "discovery of agriculture"
There's always the issue of other human nations before you get to build a space elevator without having conflict of powers. The first nation to gain access to unlimited energy basically can sustain production of humanity at little to no cost, where as other nations with no access to it has to 'pay' to use it. This invites jealously of other powers, can result in them attacking or threatening the owners of a space elevator, thus the powers having control of absolute infinite energy source would be paranoid of those without it. Look at Gundam 00 where 3 super powers had space elevators and some smaller nations still are at war regardless of the situation.
no, if you built an elevator to space it would take a lot longer to get up there than would be worth it and if you're talking about an elevator to the moon than only an idiot thinks we can make a functional elevator to the moon
It's scientifically very possible to build an elevator to the moon.... it'd just have to have a magnetic based attachment point that allows the moon to still freely orbit. It'd be wildly expensive for the overall benefits, but is definitely within the wheelhouse of even modern technology, if we really really wanted to pursue such a baseless endeavor.
10x stronger than steel *at the same weight* graphene is super light.so your saying id need a block as thick as a car to stop a bullet...are you sure? Maybe im confused...
no, because they are incredibly tiny and would just bounce off your intended victim (remember skin is far thicker than the stuff they're testing). Also drag would ensure that the effective range is only a few inches at best.
Laminates of graphene and diamond/Q-carbon (several thousand layers each) would be much like the armor of IRON MAN, though much lighter (I assume). It could also incorporate internal electronic circuitry including super-capacitors to store power and electronic sensors/processors (weapons?) internally. The Martian spaceship in the movie 5 MILLION YEARS TO EARTH seems similar...
They still can't make large (read visible) sheets of graphene reliably. We're still decades away, but! We've got gaseous lithium ion batteries coming soon! Lithium ion batteries that have triple the lifetime!
At the current rate of research and I'm obviously just guessing, I won't expect to see one for at least another 10-20 years in the consumer market. That is best-case scenario. As with any graphene project, manufacturing is still too costly and complex. That is currently the major limiting factor right now.
Sinbreaker Oh, actually a PhD candidate in delft university found a way to make high quality graphene at 1/1000th the cost. This was like 2 or 3 weeks ago from today's date 2/16/2015
some start up companies claimed that they are going to mass produce in late of 2015 like Zap&go. they are well funded on Kickstarter. according to them, their charger can be charged in 5 min and have enough energy for iphone.
Graphene can do everything except leave the lab.

Graphene was already hyped by one of my professor in college way back 2010. So much potential yet until now we havent seen actual application.

Graphene condoms?
A condom is one of those things you need to have 100% confidence in.
Trust me on this one...
im pretty sure graphene is similar to plastic so its not a good idea because rubber is more effective and better lubricated
one word: ouch
Graphene is a semimetal not a polymer, and it could be used in a composite material with rubber for lubrication.

Make weapons out of it? I'd be happy with a few pairs of socks that stayed in shape and never get holed.

Is it a good design though? Would be more efficient to just use a flexible material. Having a Fluid inside your vest is weight as well as the potential for it to leak out for some reason leaving you more exposed.
Non-newtonian fluids dont work like that moron.
A sudden impact like a bullet would make obleck harden immediately try dropping a hammer onto oobleck so it doesn't make a difference
Scott, I don't see any conceivable way that would work. When non-Newtonian fluids are hardened by pressure, they also become brittle. That might work if you are hitting the body armor with a hammer, but bullets are penetrative, and would simply break through the fluid.

yes because that is the biggest problem we have
it is a big problem, roads cause a lot of damage not just to peoples pockets by ruining their cars but it also wastes a cities money that could be put to better use
they would be wasting much more money producing graphene for something as trivial as roads
Sren this doesnt have to be a first worry but once we find a way to make it cheap and mass produce it should be somthing we consider greatly
I'd like real bullet proof clothing
if this set up were to be used as a weapon would it be a violation of the Geneva convention? (shrapnel too small to see in an x-ray)
Yeah i don't think they care much about the rules.
Does this take into consideration the differential behavior observed between the same material at the macro, and microscopic levels?
It is going to be interesting when graphene is developed enough for mass production. Ballistic protection is just the tip of the iceberg.

3:00 why do you show the graphene film with individual atom bond strings but the micro projectile is a solid ball?
That is a lattice of graphene 3 microns thick, or 3 millionths of a meter. Atoms are closer to 0.1-0.5 nanometers, or 0.1-0.5 billionths of a meter.
It's simply easier for the demonstration if the material has a recurring pattern.

Yes, we have for example Samsung mobile phones charging wireless, but that requires placing your Samsung device on a charger. So, after 13 years we still don't any advanced form of wireless charging.
There are different types of expectations though. For example, it's common sense for radio wireless charging to be extremely inefficient as you're shooting a cone into a device, with 90% or so of the energy dissipating. Wireless charging has always been about induction, and not radio ionizing which I think you're referring to. And like you said, induction is everywhere from cars to phones now.
But graphene is much more practical. And with recent synthesizing techniques just discovered a few months ago, it can be mass produced much easier now.

Donald duck-1984 graphene production is increasing exponentially. I think by 2019 we will see it everywhere
Are there Graphene bullets or arrows yet?
How do you shoot something that small at such a high speed?
Probably a small coilgun with their dust-like metal particle put into it, just a series of coils that apply a magnetic force to the metal ball and propel it forward. Obviously done in a vacuum.
I've searched and they used lasers, they put a very thin sheet of gold behind it and shoot it with a laser, the gold vaporizes and propels the microbullet.

Witchcraft. Better known today as particle physics 😂
so this in combination with spider silk amor could basically be a really good sub dermal set of body armour. couple that with traditional armour reinforced (or outright made of graphene as well.) and you'd have really friggin good armour. not to mention sub dermal armour is virtually undetectable, unless under X-rays. (I'm assuming X-rays would pick it up, but you wouldn't really be able to get rid of it, since its already under the skin of the wearer.)
i imagine captain america just holding up a cloth to protect himself
But does it have the same strength at freezing temperatures?
Very good explanations!
The beauty of the youtube comments section is the way it demonstrates how easily humans interact in a positive and prroductive manner. /s
Just because there are conflicting theories doesn't mean it isn't productive.
In fact, it's what makes our science and tech function and improve. Conflicting theories, the best ideas clash to form better ones.
What about a space elevator? Could this be used one day to make an elevator to space a possibility?
I feel like this feat is a technical issue and not a theoretical issue anymore. And it would revolutionise the world in a big way. It'd be the next "industrial revolution" or "discovery of agriculture"
godonlyknows13 we going to space, bois.
There's always the issue of other human nations before you get to build a space elevator without having conflict of powers.
The first nation to gain access to unlimited energy basically can sustain production of humanity at little to no cost, where as other nations with no access to it has to 'pay' to use it. This invites jealously of other powers, can result in them attacking or threatening the owners of a space elevator, thus the powers having control of absolute infinite energy source would be paranoid of those without it.
Look at Gundam 00 where 3 super powers had space elevators and some smaller nations still are at war regardless of the situation.
no, if you built an elevator to space it would take a lot longer to get up there than would be worth it and if you're talking about an elevator to the moon than only an idiot thinks we can make a functional elevator to the moon
It's scientifically very possible to build an elevator to the moon.... it'd just have to have a magnetic based attachment point that allows the moon to still freely orbit. It'd be wildly expensive for the overall benefits, but is definitely within the wheelhouse of even modern technology, if we really really wanted to pursue such a baseless endeavor.
+Jake Hix lol, yea. We can probably be traveling to other planets now. But they're not so important as to invest our money into right now.
Not to burst your bubble but graphene is currently 3x more expensive by weight then gold...
10x stronger than steel *at the same weight* graphene is super light.so your saying id need a block as thick as a car to stop a bullet...are you sure? Maybe im confused...
The future of light weight impervious space craft for human exploration.
What if graphene was layered with Kevlar? Just wondering.
Can it stop bullets
this has DARPA written all over it
What would that micro bullet do to someone? So many questions. This graphene stuff is interesting
So it’s elastigirl essentially
Would a microbullet be the perfect murder weapon? because it would be just about undetectable
no, because they are incredibly tiny and would just bounce off your intended victim (remember skin is far thicker than the stuff they're testing). Also drag would ensure that the effective range is only a few inches at best.
It makes good radiation shielding too. Many awesome uses in space.
I'm pretty sure that's what 's on the tie fighters.
Laminates of graphene and diamond/Q-carbon (several thousand layers each) would be much like the armor of IRON MAN, though much lighter (I assume). It could also incorporate internal electronic circuitry including super-capacitors to store power and electronic sensors/processors (weapons?) internally. The Martian spaceship in the movie 5 MILLION YEARS TO EARTH seems similar...
Can Graphene be bonded to Kevlar?
1:49 on an equal weight basis... yup. What about volume?
The pen is truly mightier than the sword, but the pencil!.... let me tell you....
They have Aluminum glass now , 8 times stronger
Where are my graphene super capacitors?
They still can't make large (read visible) sheets of graphene reliably. We're still decades away, but! We've got gaseous lithium ion batteries coming soon! Lithium ion batteries that have triple the lifetime!
can it stop my toe from stubbing ?
When we'll see graphene super capacitor batteries? ??
At the current rate of research and I'm obviously just guessing, I won't expect to see one for at least another 10-20 years in the consumer market. That is best-case scenario. As with any graphene project, manufacturing is still too costly and complex. That is currently the major limiting factor right now.
Sinbreaker Oh, actually a PhD candidate in delft university found a way to make high quality graphene at 1/1000th the cost. This was like 2 or 3 weeks ago from today's date 2/16/2015
some start up companies claimed that they are going to mass produce in late of 2015 like Zap&go. they are well funded on Kickstarter. according to them, their charger can be charged in 5 min and have enough energy for iphone.
This proves CGP Greys theory.
Hexagons are the bestagons.
