So glad that here, 4 years later, graphene is everywhere and is the true savior of modern times, found in everything and making our lives better in every conceivable way. Combined with fusion energy, it is truly the world of tomorrow, today!

Well yes, according to this article graphene-enhanced batteries have been around for quite a while now. https://www.graphene-info.com/graphene-batteries But graphene-based batteries are still yet to go into production it seems like.

GRATOMIC INC. has a superior supply of graphite in Namibia. Partnered with Perpetuus Advanced Materials who have over 500 customers for their graphene. Together, they will commercialize graphene enhanced racing tires later this year. Road tested with 5/6 major tire manufacturers for 15 months and were impressed with the results. GRATOMIC.CA

I got an idea for computer storage Graphene punch cards. Let me say how it would work. A punch card is a piece of paper with holes in it. A graphene punch card would be 1 atom think. To store the data on this, individual atoms would be taken out of the graphene. Imagine how much storage a pint-size punch card system would hold. To delete the data, the carbon atoms would fill in the graphene punch card holes. Pretty cool huh?

Ok... So 3 years later (from this video) , we are still not seeing graphene in a wide variety of products (batteries, conductors, and other materials). Why is this? Is it expensive to produce? Is it too good to be true? Standard adoption delay? I'd love to see a follow up video on this.

Hank I love you. Seriously you and your brother do great work. But I can't show this to my non native speaking English class. Most of them are familiar with English enough to hold a decent conversation. But you're talking too fast and unclearly here to be understood by less skilled speakers.

well I have noticed a big advancement in computer technology with memory and processing speeds but I also have noticed a slow development in graphene and broad scale of applications and found a similar material called Boron Nitrite nano tubes like carbon nano tubes they show the same hexagonal shapes as carbon dose so whats the difference is my question to ask?

Dude, imagine if we put like the carbon nanotubes in like graphene sheet and make like crapzillion interconnected layers of it and stick it into like biocomputing motherbord gaenetically ingeneered for optimum performance, add holographic memory and connect it all together with supercondcuting otical fiber. That would be just AWESOME !!!

an elephant standing on a pencil point to pierce a piece of graphene as thick as plastic wrap? if graphene is one atom thick piece of graphite how many atoms thick would graphene as thick as plastic wrap be? If you stacked graphene then it would be graphite and wouldn't be any stronger than the pencil lead the elephant is standing on. So pull that one atom thick graphene of the tape stretch it then walk on it . then I'll be impressed.

Electrons DO NOT fly around in any material. They freely float but their drift velocity is slow! An E field translates energy across the sea of electrons at a fast rate but the e stay in place. Kinda like a Newton's cradle.

How to make a lot of graphene: Get a big piece of tape(like huge) Then get a crane to lift the tape on graphite. Next lift off. Finally somehow get it off the tape.

Quentin smith (2 года назад)
I don't get it, how does it retain its properties when you grind it up? I would have thought that if you grind up a layer of carbon atoms one atom thick it would break the bonds between carbons and essentially form graphite? Or the bits of layers would bond through van der waals forces to form graphite? Also does anyone know how graphene composites are made?

how much global resources to convert graphite to graphene and then graphene to applicable uses in all steps? are the processes safe for the environment and people? is graphene safe for ppl to be around all day everyday in low quality but in many low low low low low quantities adding up of many objects screen here, there, all over in a room full of say 200 people?

Graphene was discovered during the second world war and was first used to replace aluminum strips that were called Chaff.
Najey Rifai (2 года назад)
+Artytom Inquisitive Minds That's interesting, I'll have a look on WoS for it. Thanks for the info buddy :)
Artytom Inquisitive Minds (2 года назад)
I don't know how they did it but the speaker used the word Graphene and they used it as chaff because it was more efficient than aluminum. The scientists made the chaff in 3 days and he remarked that this was amazing as it took 2 years to make the same thing now. So he was convinced he was referring to Graphene.
Najey Rifai (2 года назад)
+Artytom Inquisitive Minds But in terms of independent graphene sheets?
Artytom Inquisitive Minds (2 года назад)
The term Graphene goes back much further than WWII. Robert Murray Smith mentions in one of his videos that it is over 120 years old.
Najey Rifai (2 года назад)
+Artytom Inquisitive Minds But that's graphite, not graphene, right?

First of all, the graphene can be mass produce. Secondly,  we can use graphene as oil-water separator for oil industry, which can lower their cost about TWO dollar per barrel. Moreover, we can use graphene as air filter which is better than 3M.  It is made in CHINA. How do I know? Because we made them.

Surprisingly, we are already mass-producing it! Basically, carbon is heated up to 1,100 Celsius in a copper chamber, and voila! Actually it's not that simple, but we are making larger quantities of it.
Neil Gupta (2 года назад)
I still don't understand how graphite is different from graphene other than it being just one layer.
Bruce Ryan (2 года назад)
Graphene is layered in discrete layers. Graphite is random structures.
