This research, announced last week in Nature Synthesis, fills a longstanding gap in carbon material science, potentially opening brand-new possibilities for electronics, optics and semiconducting material research.

"The whole audience, the whole field, is really excited that this long-standing problem, or this imaginary material, is finally getting realized,"

 

 I hope we can see significant innovation using this, just when silicon is reaching its limit.

For better understanding of graphyne and how it is different from graphene watch the video below.

The article below shows how graphyne is good for electronics.

Basically graphene on steroids!? Sounds very interesting. 🤓

 

Just need to figure out how to make tons of this stuff fast and for less than one beeeeeellion dollars.

Simply amazing to see how different structures and bonds make these materials so incredible.

For a moment there I thought this was about Graphene and was confused... Neat stuff. 
While I don't expect to see transistors made of it anytime soon, I'm particularly interested in this application:

Graphyne is also promising as a desalinator. Its double and triple carbon bonds form holes big enough for water molecules to go through but are not large enough for sodium and chlorine ions. This innate quality of graphyne offers another possibility for the alleviation of fresh water shortages around the world and other related ecological challenges.

Carbon is the coolest element,there are so many things we can do with it and so much potential.

Carbon is a great semi-conductor and has monstrous hardness and strength.

That's not Graphene, this is Graphene

 

The photo of the Graphene sample was taken in the Georgia Tech Nanotechnology Research Center:

Still waiting for graphene to replace silicon as we are endlessly promised... don't hold your breath on this one getting to consumer electronics any time soon. The thing with silicon is that it's common, cheap and easy to work with; it's not enough to find a material that is theoretically better, it has to be practical too.

Don't ask to ask, just ask... please 🤨

And that's where Silicon Carbide comes in.

Carbon Fiber:

i dont really like carbon fiber... they say its "hard" but in reality its also really brittle... even planes have issues with it (currently,  even though its really old tech by now, you'd think they'd figured it out). It also smashes in a billion sharp pieces, its really not that great as a building material (even though it has obvious advantages like weight,  but everything comes at a price, figuratively )

 

but yeah, carbon itself is pretty cool 😎

so, erm, does this have similar properties as graphene or is it easier to work with? Because they didn't figure that out yet either... but I read they found some "folding tech" for use as a "transistor"... that would be useful i suppose.  Origami stuff is fascinating anyways,  its crazy what can be done with this (mechanically) 

 

 

ps: also missed opportunity should be "for the first tyme" in the title 😉

Interesting,I have read that Carbon Fiber wears down machining tools pretty quickly so it's definitely a very hard material.

I wrote nonsense so i corrected that.

FYI in materials science "Hardness" is a measure of it's resistatance to erosive forces, whilst toughness is it's resistance to shattering.

 

The most obvious day to day material you might run into with a high hardness and a low toughness is high carbon steels. They retain sharp edges and the like well, but tend to break or shatter rather than bend.

yeah, it totally depends on the use case  But as with the planes (Airbus with issues currently i think) you'd think its the perfect material,  lightweight,  sturdy... except it somehow isnt and their planes just kinda self destruct and need constant extra maintenance...

 

I kinda almost think its too rigid for planes maybe? but its also design probably... just because a good material is available doesn't mean people fully understand how to... 

 

Space X also wanted to make carbon fiber rockets... i don't think they did...? 

 

Basically i don't hate the material,  i just think its a bit overhyped... similar to graphene, which is even worse... great material... no (known to me) actual use cases... 🤔

ah, i didn't know that either... but as i said carbon fiber seems a bit brittle... you can even rip off pieces with your fingernails sometimes lol (probably not when its "brand new" but thats the point things age...)

 

tldr. great material,  very high maintenance cost (so maybe not so great for many use cases)

 

ps:  Boeing 787

"At launch, Boeing targeted 20% less fuel burn than replaced aircraft like the Boeing 767, carrying 200 to 300 passengers on point-to-point routes up to 8,500 nmi (16,000 km), a shift from hub-and-spoke travel. The twinjet is powered by General Electric GEnx or Rolls-Royce Trent 1000 high-bypass turbofans. It is the first airliner with an airframe primarily made of composite materials"

 

I think that one doesn't have issues? 

 

Also the devil is in the detail, they don't use carbon fiber,  they use carbon fiber "composites". 🤷‍♂️

It may be practical in some use cases but it's expensive.

There are use cases for graphene: Interconnects for semi-conductor industry,diodes,LEDs.

But seems like it's difficult to produce,so difficult that there is only one source of photos for a graphene sample that is visible to the naked eye.

The intro for this song is the exact same "News update" sound in this video:

And I was seriously thinking that I somehow had two tabs open or my phone (which plays through the same headset) started playing music because this song pops up a lot.
