Why does the graphite in the pencil not have similar qualities? Isn't it essentially the exact same thing as graphene except stacked together? Why is one layer of graphene stronger than a solid piece of graphite? Why do the atoms in graphite not want to be evenly spaced; but they do like being evenly spaced when they are in a single layer?
The layers of graphene in graphite is easily removed from the graphite, meaning it is easy to break the graphite into smaller pieces of graphene. When breaking apart the graphite, you do not destroy the bonds of the material, but just remove the layers of graphene. I can elaborate further if needed.
While layers of graphene inside graphite behave as in the video, the bonds between these layers are very weak and corrupt all the advantages. Thus graphite is excellent in two dimensions, but very weak in the third. Moreover, the orientation of bits ("crystals") of graphite is not all the same, and they are not united into a single crystal like a diamond, therefore what might be the right dimension for one bit is a wrong one for another, so everything becomes more-or-less a mess.
ty_ger The carbon atoms in the graphite aren't in that perfect lattice yet - all the atoms are jumbled together and create weak bonds in every direction rather than strong bonds in single directions. Remember, for the graphite to become graphene they had to make a pile of graphite and slice it down repeatedly until it locked into a single layer and became graphene. Saying graphite and graphene are essentially the same is like saying diamonds and coal are essentially the same. How a thing is built has just as much to do with its function as what a thing is made of.
***** Resorting to name calling is fairly petty, but I'll try to clarify: Pure graphite is composed of Carbon atoms. In graphite, those atoms are arranged in such a way as to create weaker bonds in all directions with atoms at varying distances, because carbon atoms _want_ to group up and share electrons with other carbon atoms, however graphite as a substance has a very high viscosity - the atoms aren't allowed to move around easily to strengthen those bonds. Now if we take a big clump of pure graphite and applied tons of pressure to it from all sides the carbon atoms would start to move closer and closer together and create stronger and stronger bonds, until it hits a certain point where the atoms can't get any closer to each other and they form a 3-dimensional lattice-shape. At that point every carbon atom has a *very strong* bond to every _other_ carbon atom nearby, and we've created Diamond. *_SAME ATOMS_*, different configuration. EDIT: As an analogy, think of a snowball. At first, it's loosely clumped together; almost falling apart. So you take your hands and _squeeze_ it from all sides until it gets harder. It might even get so hard that it turns into ice instead of snow. *_SAME MOLECULES_*, different configuration. In graphene the atoms arrange in a similar configuration to diamond, but along a single plane. Since it's in a single layer, the atoms have extra electrons that aren't bound to other carbon atoms in other directions so it becomes an incredible conductor. EDIT: Extending the analogy, imagine the difference between a meter of snow compared to a layer of ice. If you jump into the snow, it sprays and breaks off into smaller and smaller bits. On the other hand if you run on ice, you'll slip and slide around because of the way that it's structured. *_SAME MOLECULES_*, different configuration. The reason we don't see graphene appear naturally is that very little in the universe happens along a single axis on its own - the atoms innately jumble together unless something acts on them.

I think one of the most exciting applications of graphine is water filtration. Since a water molecule but nothing larger passes through graphine without resistance it can purify water with almost no energy input. Some scientists think it could permanently solve the worlds clean water problem by enabling oceanic water treatment facilities with very low energy input.

There is a difference between strength, hardness, and toughness. For example, a diamond is one of the hardest minerals, if not the hardest, with a score of 10 on the Mohs scale - it can cut anything but can only be cut by things as hard as itself.; however, it's not very tough - you can shatter it with a hammer. Tensile strength is how well it can resist a force trying to pierce it or pull it apart. Also, graphite is not the same thing as graphene - graphene is a single layer, where graphite is many layers stacked on top of each other. The pencil is breaking between the layers.
Graphene is a single layer of graphite. Graphite is a material that peels of layers because the bonds are very weak but once you get to a single layer there is no more to peel off. This is the difference between them.

In graphene and graphite layers, there are 3 strong sigma bonds in the plane of the layer and 1 weak metallic-style delocalised "glue" bond. in graphene, all the layers are in the same plane, meaning that all of the strong bonds stick strongly in one direction; in graphite the layers are jumbled up in different planes so that the graphite is uniformly strong but not exceptionally strong in any given direction due to the easy to break bonds between layers.
A single layer of atoms can support the weight of an elephant concentrated into the size of a pencil? I cannot believe that. It might make a good video. It's easy to test in a materials lab. Provided you can find a reasonably large slice of graphene.
+Veritasium Well... the one with the elephant is misleading (if not just plain wrong). A single layer of graphene can hold only 4 kg without breaking. But multiple layers stacked on top of each other (with a total thickness comparable to that of paper) COULD hold that elephant on a pencil. Just saying...
Triboluminescence is an optical phenomenon in which light is generated through the breaking of chemical bonds in a material when it is pulled apart, ripped, scratched, crushed, or rubbed. The phenomenon is not fully understood, but appears to be caused by the separation and reunification of electrical charges. Triboluminescence can be observed when breaking sugar crystals (especially Wint-O-Green Life Savers) and peeling adhesive tapes.

"The earliest TEM images of few-layer graphite were published by G. Ruess and F. Vogt in 1948"'.

Graphene oxide is not a sheet of graphene. To answer your question, almost transparent and nearly impossible to feel- easy to tear, even. It's the relative strength that counts.
antiHUMANDesigns That's correct. The actual color of graphene is in fact a very dark, blackish grey but due to the molecular structure what we see is near-complete transparency.
(sorry,just had to write a few notes for myself) Thinnest material known to man, strong, best thermal conductor, good conductor of electricity. Nano tech (devices or material less than 10 nanometers in size) Nanometer = a billionth 1/1,000,000,000 of a meter. About the size of ten atoms. Pencil has graphite which has carbon in a hexagonal bleh When you write, sheets of those graphite stick to the paper, usually many layers at a time, sometimes there's a single layer of carbon atoms and that's graphene It conducts electrons faster than any other substance at room temperature. No atoms out of place. Strong but flexible bonds. Scientists making faster touch screens, more efficient solar panels, tougher material, and better computers with nano tech (probably other stuff too)
So i could make graphene using tape, and while this graphene stuck to the tape is super strong, i wouldnt be able to say, stab a pencil through the tape and the graphene as well?
Felix Coreston and that means we could make flying saucers outta this stuff. Spider silk is stronger than steel, btw, which will be perfect for spacesuits ....(-:

because every layer itself is super strong, but a lot of layers aren't. it's like a bunch of paper. you can easily slide the one at the top to the side, right? (your force is parallel to the bunch of paper) but it's harder to tear one sheet of paper apart. (the force is parallel to the surface of the paper) : ] hope it helped a bit

so if one layer of atoms taken from a penciltip is stronger than diamonds and a pencilmine itself persists out of millions of those layers, how come that the pencilmine itself isnt stronger as diamonds?
Although I think that when you have a 1 Atom thick Graphene then its stronger rather than billions of layers of graphene making graphite. I guess it has something to do with the fact that you can really put any actual pressure on it since its just one atom thick but Graphite is billions of atoms thick so you can actually put pressure on it and break it!
+Alpha Mineron i guess bc the strong structure only exists in 1 2D layer of graphene, and 2 layers or more on top of each other dont have nearly as strong of a connection than the single layer has. its like stacking 100 carpets on each other. 1 carpet itself is maybe strong and cant be ripped apart, but you can easily remove 1 carpet from another, and a stack of 100 carpets wouldnt be that stable either. sadly that would mean that u could never have a block of graphene or something, that would than be harder than diamond
+Roman Randhahn Well We can make a a 1 atom thick layer of graphene. The Block thing can't happen :( I would love having a Graphene Super Car so I can actually play GTA in real life :/ guess Its never gonna happen BTW, your right. The bond between individual layers Is weak that's why Graphene is stronger.
+Roman Randhahn the bond between two graphite atoms is super strong but the bond between layers of graphite is weak and hence graphene is strong but graphite is weak
In reality, the graphite in your pencil has microscopic-scale flaws. Not all of the graphite layers are perfectly aligned in the same direction. Some will be skewed in one direction or another. So the graphite will either break along the imperfections in the crystal structure or the individual layers will slide apart On a nano-scale, you are dealing with individual molecules (instead of a bulk collection of molecules like in your pencil), so the individual sheets are nearly as strong as diamond
the layers are only held together by weak intermolecular forces, so the layers arent very attracted to each other. the single layers are very strong, it's just the forces between THEM that make it so easy to break.
Because while a layer is very strong, the bond between each layer is not. Consider a sheet of paper. It hold itself together and if you grab a corner the rest will follow. Now you stack a bunch of sheet of paper together. If you kick the pile of paper it will shatter into a bunch of individual sheets of paper. This is not a perfect analogy but it should be enough to illustrate why graphite (pile of paper) is weak while graphene (single sheet) is stronger.
Im not qualified to answer this, But im going to have a chop at it. graphene is a 2D sheet. Stacking them makes graphite. If you wrap it into a tube you get a carbon nano-tube. If you wrap it in to a sphere you get a Buckyball.
Because the graphene is stacked in layers. And each layer is strong, because of the 2d hexagonal bonds. It doesn't bond in 3 dimensions, but stacks. That is why you can write with pencils. If you're looking for hexagonal carbon bonds in 3 dimensions, go look at diamonds.

Lightning won't go through two thick layers of plexiglass, through the air gap, and through you... None of those are very conductive. It'll pass through the aluminium body of the plane like a faraday cage. This is not a problem in need of fixing!
I have to confess that on a science test i was about to get a 100% and the last question was what is the hardest element that we studied in class (diamond) and because i saw this video i put down graphene to be smart and I didnt get a 100% i blame you veritasium
This is the first Vertasium Video of its kind... I LOVED YOUR EDITING AND WAY OF PRESENTATION IN THIS!!
That moment when someone drags you into a room and won't let you go until you have created the thinnest yet the most resistent material on earth with only a pencil,a sheet of paper and a scotch tape.#relatable
See y'all in 8 years when this gets in your recommendations.
Love your work guys.
These make great reference material.
Please keep making them.
I think one of the most exciting applications of graphine is water filtration. Since a water molecule but nothing larger passes through graphine without resistance it can purify water with almost no energy input. Some scientists think it could permanently solve the worlds clean water problem by enabling oceanic water treatment facilities with very low energy input.
Hi, from the future here. This video ended with an ad for "Monolayer Graphene Film" only 300 Trump Imperial Credits for 60mm x 40mm. What a capital deal!

At the time the vid was released, this was wayyy ahead of its time when it came to entertainment and knowledge
I cant explain how much I love Veritasium... and minutephysics too

i remember back then when Veritasium wasn't huge, one of the first few vids i watched. loved this channel ever since
You should make videos like this one. Now your videos are very long and you have explained in this video in an entertaining manner.

Am I the only person who want a knife made of this stuff?
***** Im thinking of a steel body with just the cutting edge made of this.

RunItsTheCat I know! >:{D
Could it cut anything? I mean, a knife is a wedge, and graphene is more like a plane.
John Sherer You could always orientate 2 planes to form an edge.
Great.. Awesome... Outstanding
If graphene is so strong, why does pencil lead break so easily?
There is a difference between strength, hardness, and toughness. For example, a diamond is one of the hardest minerals, if not the hardest, with a score of 10 on the Mohs scale - it can cut anything but can only be cut by things as hard as itself.; however, it's not very tough - you can shatter it with a hammer. Tensile strength is how well it can resist a force trying to pierce it or pull it apart.
Also, graphite is not the same thing as graphene - graphene is a single layer, where graphite is many layers stacked on top of each other. The pencil is breaking between the layers.
Graphene is a single layer of graphite. Graphite is a material that peels of layers because the bonds are very weak but once you get to a single layer there is no more to peel off. This is the difference between them.
***** Oh please. You know for someone who has a master's degree (which you don't) you act like your're some kind of bad ass. Are you kidding? I'm not old enough but I can guarantee that I can get a master's in what you get. It has nothing to do with not being intellectual enough. Also for a college graduate you're grammar is absolute garbage. Next time if you're going to tell someone their not intellectual enough, at least make sure you can properly type sentences. Unbelievable. Or you're some kid who is seeking attention.
***** So what are you exactly, a late 20 yr old with the temper of someone who is 4? trying to impress some faceless blobs of text disagreeing with you on the internet? I realize that is exactly what I am doing but I don't pretend to be better than my equal man. If all of your years of schooling have still brought you no wisdom, I would please ask you to get off of the internet and off of my level, sir.
cool...
That is a really good video...
Ya
2021 still waiting for graphene revolution
that was a great vid, loved it
In graphene and graphite layers, there are 3 strong sigma bonds in the plane of the layer and 1 weak metallic-style delocalised "glue" bond. in graphene, all the layers are in the same plane, meaning that all of the strong bonds stick strongly in one direction; in graphite the layers are jumbled up in different planes so that the graphite is uniformly strong but not exceptionally strong in any given direction due to the easy to break bonds between layers.
That missing comma at 0:45 makes me question if I want to use commas in numbers or not.
I wish that voice helped me in my exams
A single layer of atoms can support the weight of an elephant concentrated into the size of a pencil? I cannot believe that. It might make a good video. It's easy to test in a materials lab. Provided you can find a reasonably large slice of graphene.
I have absolutely no idea who dislike such great videos?

Oh Derek you are so charming its unbelievable

Michal Korcak so ur were like "oh Newton's Laww aawww awwwww"?
D'awww
+Veritasium Well... the one with the elephant is misleading (if not just plain wrong). A single layer of graphene can hold only 4 kg without breaking. But multiple layers stacked on top of each other (with a total thickness comparable to that of paper) COULD hold that elephant on a pencil. Just saying...
Correct me but graphene have layers it would become WEAKER.
+Trainer_Poke note : I'm not sure
No. The individual layers would remain strong. But the forces holding together two or more layers are weak.
toni8675 ok thx
You're wrong you fucknut.
Triboluminescence is an optical phenomenon in which light is generated through the breaking of chemical bonds in a material when it is pulled apart, ripped, scratched, crushed, or rubbed. The phenomenon is not fully understood, but appears to be caused by the separation and reunification of electrical charges. Triboluminescence can be observed when breaking sugar crystals (especially Wint-O-Green Life Savers) and peeling adhesive tapes.
This is the funniest science video ever created!!!
I think it is odd that he never mentioned how balls off the wall expensive the stuff is to produce.
there is a company that has a method to produce graphene that is affordable.
Mateusz J What is its name? What is the method? How much does it produce and in what amount of time? Also, could you please define what you mean by affordable.
***** I'm not saying it's not true. I just want to know what it is. I think it would be amazing if it were true, but I personally need proof. I'm sorry.
Andrew Halverson The company is called
'Azoty Tarnow'. Unfortunately they didn't give any details of how it's made.
Andrew Halverson look up how to make it now, you can make yourself dirt cheap
Can you extract single atom thick graphite layers from pencil leads? Can't right? From what I know pencil leads are mede of powdered graphite and clay
*made 😖
yeah but if I'm correct even very fine powder is of micro meter range particle sizes. So such particles have many graphite layers.
I didn't think of that :)
Now, there's carbyne.
I like the lecture David Sereda gave about the revolution of Graphene and how it will be used! Really Amazing!!
Got this in my reccomended
"The earliest TEM images of few-layer graphite were published by G. Ruess and F. Vogt in 1948"'.
Although, the most advanced- so far and by far- method of obtaining the graphene on a quazi-mass scale was discovered... it's hard to say that was invented... in Poland a decade ago or so !
The Blue Laser as well...
First professional computer in Europe made on a mass scale also in Poland- The ODRA- 1972
A Pole Copernicus busted Ptolomenian Solar Orbiting the Earth theory in 1543.
Maria Curie was a Polish girl.
Polish mathematicians; Rejewski, Zygalski and Rozycki broke the Enigma code in 1932...
Serendipity and Eureka rolled into one; yet... who cares ?!
Folks in China, Russia, India... everywhere out there have already taken advantage of it, made their own usage of the Polish inventions and discoveries..
Who cares ?!!!!
Well... I do!
Cheers guys !
All this but Poland STILL cannot into space.

Well...a good sport of you...
Anyway, some Poles are working on that...
By the way... Mr. Twardowski was according to the urban legend first into the moon back in XVII c.

but what does a sheet of graphene actually look like and feel like in real life?
Graphene oxide is not a sheet of graphene.
To answer your question, almost transparent and nearly impossible to feel- easy to tear, even. It's the relative strength that counts.
Ty Gísli
should look about like graphite its thin gray etc what we're doing now i don't know but the color wont change ,though transparency will
MyGamingTV I heard it's more transparent than glass.
antiHUMANDesigns That's correct. The actual color of graphene is in fact a very dark, blackish grey but due to the molecular structure what we see is near-complete transparency.
(sorry,just had to write a few notes for myself) Thinnest material known to man, strong, best thermal conductor, good conductor of electricity.
Nano tech (devices or material less than 10 nanometers in size)
Nanometer = a billionth 1/1,000,000,000 of a meter. About the size of ten atoms.
Pencil has graphite which has carbon in a hexagonal bleh
When you write, sheets of those graphite stick to the paper, usually many layers at a time, sometimes there's a single layer of carbon atoms and that's graphene
It conducts electrons faster than any other substance at room temperature. No atoms out of place. Strong but flexible bonds.
Scientists making faster touch screens, more efficient solar panels, tougher material, and better computers with nano tech (probably other stuff too)

So i could make graphene using tape, and while this graphene stuck to the tape is super strong, i wouldnt be able to say, stab a pencil through the tape and the graphene as well?

This is simply an observation (not a dis or otherwise) your accent is much more pronounced(pardon the pun) here in one of your earlier videos than in any of the video from the last 4 or so years since I have been watching your UA-cam channel. Please continue to make high quality science videos and please continue to not let those quintessential human emotions of pride and down right pig headedness get in the way of doing what you do. Science isn't about being right that one time but about amending your model to fit reality and I hope you continue to do so with the quality and charisma that you do in 2017.
because every layer itself is super strong, but a lot of layers aren't.
it's like a bunch of paper. you can easily slide the one at the top to the side, right? (your force is parallel to the bunch of paper) but it's harder to tear one sheet of paper apart. (the force is parallel to the surface of the paper) : ]
hope it helped a bit

Sir the was not correct please let me know what is 1.07 song
so if one layer of atoms taken from a penciltip is stronger than diamonds and a pencilmine itself persists out of millions of those layers, how come that the pencilmine itself isnt stronger as diamonds?
This needs to be answered!!
Although I think that when you have a 1 Atom thick Graphene then its stronger rather than billions of layers of graphene making graphite.
I guess it has something to do with the fact that you can really put any actual pressure on it since its just one atom thick but Graphite is billions of atoms thick so you can actually put pressure on it and break it!
+Alpha Mineron i guess bc the strong structure only exists in 1 2D layer of graphene, and 2 layers or more on top of each other dont have nearly as strong of a connection than the single layer has.
its like stacking 100 carpets on each other. 1 carpet itself is maybe strong and cant be ripped apart, but you can easily remove 1 carpet from another, and a stack of 100 carpets wouldnt be that stable either.
sadly that would mean that u could never have a block of graphene or something, that would than be harder than diamond
+Roman Randhahn Well We can make a a 1 atom thick layer of graphene. The Block thing can't happen :(
I would love having a Graphene Super Car so I can actually play GTA in real life :/ guess Its never gonna happen
BTW, your right. The bond between individual layers Is weak that's why Graphene is stronger.
+Roman Randhahn the bond between two graphite atoms is super strong but the bond between layers of graphite is weak and hence graphene is strong but graphite is weak
1 atom thick condoms?
Graphene isn't /that/ flexible.
+Alan Johnson and its surely indestructible! can we use this all over again? 1000 times hahahaha
+Robby trebor The necroposting is real.
tape was scratching her and the pencil dust rubbed off
The guy with you is totally an antique piece.
In reality, the graphite in your pencil has microscopic-scale flaws. Not all of the graphite layers are perfectly aligned in the same direction. Some will be skewed in one direction or another. So the graphite will either break along the imperfections in the crystal structure or the individual layers will slide apart
On a nano-scale, you are dealing with individual molecules (instead of a bulk collection of molecules like in your pencil), so the individual sheets are nearly as strong as diamond
This is a simultaneously adorable and informative video!
the layers are only held together by weak intermolecular forces, so the layers arent very attracted to each other. the single layers are very strong, it's just the forces between THEM that make it so easy to break.
@ 3:31 when two bodies of different mass collide with each other, the smaller mass body approaching a larger mass will bounce back in a collision. :-)
Wanna be a nanotechnologist but BY LAW my UA-cam account MUST be the center of my whole life (aside from my mom, of course)
Because while a layer is very strong, the bond between each layer is not.
Consider a sheet of paper. It hold itself together and if you grab a corner the rest will follow. Now you stack a bunch of sheet of paper together. If you kick the pile of paper it will shatter into a bunch of individual sheets of paper.
This is not a perfect analogy but it should be enough to illustrate why graphite (pile of paper) is weak while graphene (single sheet) is stronger.
As an artist who often works with graphite, I found this very interesting.
Didn't know, winning a Nobel was that easy.😁
A real case of the pencil being mightier than the sword
Im not qualified to answer this, But im going to have a chop at it.
graphene is a 2D sheet. Stacking them makes graphite.
If you wrap it into a tube you get a carbon nano-tube.
If you wrap it in to a sphere you get a Buckyball.
Because the graphene is stacked in layers. And each layer is strong, because of the 2d hexagonal bonds. It doesn't bond in 3 dimensions, but stacks. That is why you can write with pencils. If you're looking for hexagonal carbon bonds in 3 dimensions, go look at diamonds.
