Penta-Graphene, A New Structural Variant of Carbon, Discovered

Penta-Graphene...

Researchers have discovered a new structural variant of carbon called 'penta-graphene' -- a very thin sheet of pure carbon that has a unique structure inspired by a pentagonal pattern of tiles found paving the streets of Cairo.

phys.org...

www.sciencedaily.com...

Most forms of carbon are made of hexagonal building blocks, sometimes interspersed with pentagons. Penta-graphene would be a unique two-dimensional carbon allotrope composed exclusively of pentagons.

Looks like this new material will be incredibly strong and will be able to withstand extremely high temperatures. The fact that Penta-Graphene is nothing but pentagon shapes is pretty bizarre. It will be interesting to see this material in action in the years to come. I wonder how it will be used and what sort of products will be made from it...

Space elevator?

Not unless is was for a 'live' version.

"When you take graphene and roll it up, you make what is called a carbon nanotube which can be metallic or semiconducting," Jena said. "Penta-graphene, when you roll it up, will also make a nanotube, but it is always semiconducting."

Wonder if it explodes when you flashy-thing it like regular graphene?

Hold plasma? Interstellar travel space ship material? Clothes? Greenhouse cover? Sounds pretty cool to me a reply to: Nurelic

a reply to: Boomy327

It is cool but it is always a semiconductor which limits its use.

Tell us about these limitations...

Educate the illiterate..

Why couldnt this be used as "Heat sheilds",
"Kinetic shielding"...
Imagin thin multilayers of this on a spaceship..

So its "semicunductive"... And?

Btw this came after i posted:

Semconductive, run a charge in specific
lengths and you might get radiation shielding
as well... Worth thinking about, no?

How about you go educate yourself on the limitations of said material.

Also, straw man arguments are low.

Why do you come here hammering down your points
and refuse to explain them...
So maybe not illiterate, uneducated. Is that
better...?

I mean seriously, i want you to tell me why...
Your post is clearly saying there are limitations.
Tell us about them....

a reply to: Miccey

Straw man arguments are futile as is your attitude.

I do not need to elaborate on anything. I choose to say or not. If I choose to say it has limitations that is my choice.

If you don't agree, then you can go elaborate if you want.

Either way I choose whether or not I discuss anything.

So your basicly letting us know
you DONT know, really..

Ok fine...

Any one else.....

Asking someone to clarify their statements is not a straw man argument.

a reply to: theabsolutetruth

Wow, ease up a little... Miccey is seemingly sincere, and wants to know more. Since your first two posts were one liners (which is against T&C) I think he was also encouraging you to elaborate. Otherwise, please don't waste our time and space with your one-liners that don't add anything of any real value.

You have already started this topic off on a really irritating and annoying note, acting like people are attacking you and trying to use shill level debate tactics. Straw man arguments? Posting definitions to common words? What is your problem? Take a step back and or go get some fresh air. You have been 'interneting' too long.

With that said... I was going to discuss this penta-graphene, but this topic already left a bad taste in my mouth. Sorry to waste more space.

I read up on the phys.org link
but i cant find the limitations,,

And please, lets starve the obvious....

Can someone elaborate on limitations....

Sometimes i feel like the situation in
Stargate SG-1, were the Asgards are
having some "issues" with the replicators...

You know, were O´Neill says "I dont know Carter,
you might not be dumb enough"...
Maybe we are loosing the ability to think like,
well him...LOL, like O´Neill....

"Yea, Guns.....LOTS of guns, and C4"

Asking and rudely demanding are not the same thing.

a reply to: WeAre0ne

Perhaps it is you that should ''ease off''.

I made a factual statement. I will choose whether or not to elaborate. I also won't be goaded into responding by an obviously rude comment by a poster that appears to consider themselves some sort of ATS enforcer. Nor to comment on anything suggested by you and your interfering comments.

a reply to: theabsolutetruth

Can you please elaborate on these limitations? I am curious as to how this substance could be used, and if there are limitations I'd like to know what those are.

I love learning new things. Thanks in advance!

a reply to: ScientificRailgun

All materials have limitations. Those that are semiconducting also do. How about you go do some searching for yourself, this thread is not exactly welcoming comments.

a reply to: theabsolutetruth

I ask you because it seems you're in the know on such things. Could you please give me a little information on the limitations? I don't see how this thread isn't exactly welcoming comments. We're discussing this new material. I'm genuinely curious what it's limitations are, and you appear to know this. So I'm very politely asking for a little elaboration, is all.

Again, thanks in advance!

a reply to: ScientificRailgun

I said it is limited due to being always a semiconductor.

There isn't much specific research information on the specific properties and applications of penta graphene available as yet. However it typically is graphene and is stated as always being a semiconductor.
