Commercial Graphene Production // Allotropes and Applications

[@NicoVeenkamp]

Again you managed to explain a complex issue pretty easily. What people need to remember that, as Neil deGrasseTyson said many times, carbon has more ways to combine with itself and other elements than all other elements combined. And carbon is one of the most common elements in the universe after H, He and O. What may be missing from this video, and what you address in one of the next videos, is how a relatively small amount of, some form of graphene, enable other materials to be stronger and have a better conductivity then itself on its own.

[@thelimitingfactor]

That's a great quote by NDGT! Great question how so little can stretch so far: 1) Usually these things are done by weight. If you fill a 1 liter jar with graphene, it only holds 70g or so. So, even a few weight percent of graphene in a volume of a material has a massive impact throughout the volume. 2) It's so extreme in it's conductivity and strength. Combine 1 & 2 and that's pretty much the answer. 😃

[@NicoVeenkamp]

The Limiting Factor Neal Stephenson wrote an SF book called The Diamond Age in 1995 where he explores a world where carbon based nanotechnology is ubiquitous. In this respect Diamond Age is comparable with the Graphene Age. The term Diamond Age was coined by Ralph Merkle who together with Eric Drexler popularized nanotechnology.

[@zber9043]

Nico Veenkamp I love that book. FYI The young lady’s illustrated primer was actually inspiration for the kindle.

[@danielguffey]

@@NicoVeenkamp There was a "Diamond Age" episode of Naked Science where they explored diamond applications and diamond semiconductors. I however spoke with a diamond material scientist who said that effort had flopped. It would be interesting to see what graphene could bring back, and more information on the 1.1-degree magic angle would be very interesting to cover too.

I believe that graphene is the material of the future. However, few people seem to talk about the possible environment impact. Carbon is pretty much eternal. Carbon fiber doesnt degrade and stays in landfills for very long time periods. Are we looking at similar issues with graphene? Or are there people working on finding ways to recycle graphene materials after the initial product has expired?

[@davordebrecin2054]

[@JakeWitmer]

You mentioned that carbon could be made with less-structurally-sound larger rings. Makes me wonder about whether such rings could be formed "bespoke" into "far harder than diamond" repeating structures, that are closer to a "woven textile" in design, or high-carbon steel at a micro-scale. (I.e. With interlocking rings of carbons that, if weaker than c6 tiling by themselves, would be strong if they were linked together like chain-mail armor.) A larger version of this would be weaving together ultra-long SWNTs with each SWNT forming "a single thread, to be woven." This stuff is fun to think about. Of course, it was nearly all predicted by Drexler's "Engines of Creation." Edit: Sure enough, my memory was correct. All kinds of geometries are possible. Here's a white paper discussing them, with a graphic. It's interesting to imagine A long wire of SWNT running down the middle of a long stack of the hexagonal toroids. Would it be ultra-strong and ultra-tough? Would it carry current without breaking? Once ultra-long kilns exist, reality is going to get weird. Ideally, we all live long enough to put our brains on a mostly-carbon neuron substrate.

What about a life-straw type method of starting with graphite at the top, slowly descending into a lesser volume 'tube' while tethered on the other end by graphine. Once it's tethered, a simple gravity drop should/could pull it out like taffy. And by tube I mean literal in a sense, but whatever can step down the layers. If it can be tethered in this model as abstract as it is the strength alone should hold through the pull. Just have to figure out what the 'tube' could be.

Exactly! You can run a current through it to slightly warm it. I don't know how much energy that would take, but that's the idea. It also has other uses without electricity if it's more conductive...like in situations where you need to radiate heat away from maybe high voltage cables?
