Scientists Discover Diamond Nanothreads
First time accepted submitter sokol815 writes Penn State University scientists discovered diamond nanothreads can be created from benzene when compressed. The compression brings the benzene molecules into a highly reactive state. It was expected that the molecules would create a non-ordered glass-like material, but due to the slow speed of decompression used, the benzene molecules ordered themselves into a naturally repeating crystal. The experiment took place at room-temperature. Early results indicate that these nanothreads are stronger than previously produced carbon nanotubes, and may have applications throughout the engineering industry.
Should it be called Diamondium or Diamondillium?
Well, my sega cd doesn't have kinect so I am safe.
How about "not diamond"?
Diamond is characterized by each carbon bonding with 4 other carbons. You can't get a thread out of it. You might claim that you have, but all along that thread there will be carbons not bonded to four others. Those are called defects.
From a diamond point-of-view, this stuff would be considered defect-laden pseudo-'diamond', or just simply not diamond.
Still, sexy headline.
I come here for the love
You wouldn't guess from the summary that the article title is "Going up! Cosmic elevator could reach space on a cable made of diamonds".
Now all we need is a manwich.
This is great and all, but the real question is does this new method allow them to produce it in large quantities while maintaining its strength?
Space Elevator!
or not...
The public and the press underestimate and understate the difficulty in mass-producing new materials. Just because we can make a little, enough to study, doesn't mean we can efficiently make more or that developing those methods will be trivial or guaranteed to succeed.
Carbon nanotube production is still a tangled mixed mess 25+ years after their discovery and study. Graphene production is improving but still not good enough for commercial use 10 years after its discovery and study. These diamond nanothreads look to require 25 GPa of pressure to create. That's not a trivial amount of pressure - it's several times that required to make synthetic diamond gems. Using this materials is going to depend on someone inventing a much easier method of production, probably some form of chemical vapor deposition, which is already used for diamond films, graphene and nanotubes.
The long work of developing those methods is less sexy than the initial discovery of a material or effect, and usually a gradual improvement rather than a single "eureka" moment. It's just now starting to be recognized as a scientific achievement (e.g. the invention of reliable, efficient blue LEDs just won the Nobel prize although the physical principles were clearly understood by others decades earlier).
If it's a nuclear fusion reactor, why not call it the Sun? Because it's not.
Chemicals can have the same molecular formula without being the same thing. Further the state of the chemical can also dictate its structure.
Diamond have a face-centered cubic crystal structure. It this carbon nanothread FCC? No. The threads are "carbon in a tetrahedral formation with a carbon hanging off" (John Badding, PSU). Essentially it's non-crystalline, almost amorphous, whereas diamonds are crystalline.
Basically it needs a new name. Something to the effect of Carbon Nanothreads, similar but different from Carbon Nanotubes.
Now I'm naming my daughter Lucy and making her wear a shirt made of it. That way I can say: Lucy in the sky with diamonds!
If you make a whole bunch of this stuff, you'll use up more of the carbon that could otherwise be used for CO/2.
Carbon sinks!
On the minus side, with all the extra oxygen, the planet will suddenly explode when some unhealthy sap lights his cigarette.
So you just got the Kinect/Xbox360 gaming system
Who is just getting an XBox 360? XBox One has been out for over a year dude.
Can I have my beanstalk now? Please?
I've fallen off your lawn, and I can't get up.
Diamond Nanothreads are forever.
Yeah but the 'D' is a girls best friend
People who wanted to play only Halo 3 to finish the story, and hate Microsoft for not releasing it on PC
Using this for a space elevator isn't the best use for this. If these fibers are flexible enough, you could weave them into flexible body armor. Imagine light weight "kitchen" gloves that you can't cut through even with the sharpest knife. Shark protection (but not against lasers...yet). These fibers could replace carbon fiber in high strength areas. Have short enough fibers and use them for 3D printing. They are already using carbon fiber in 3D printers, this could replace it for extreme strength parts. If cheap enough, this could replace carbon fiber in safety situations (racing, boating, aircraft). Now imagine a crash at a race, except this time, the body deforms, but does not disintegrate. I think this is a major announcement in materials science, and I'm curious just how many other areas this could advance.
and the nerves of the AI we born.
one step closer
A "D" are a guy's best friends aswell...
I hope that the process of creating this stuff is inexpensive. Maybe one day instead of a carbon fiber fishing rod I will be able to own a diamond thread woven fabric shaped into a hollow fishing rod.
But seriously this new material will likely open up numerous serious products. We might even see computer chips wired with this material.
each to their own, I prefer a pair of them to a single D.
I think I have a machine that makes this stuff all the time as a waste product. Unfortunately, it is likely to be quite difficult to extract the nanothreads as they are a tiny part of the residue in the diesel particulate filter in the exhaust of my car's diesel engine!

Not sure why we'd want to post to a CNN article. Here's the scientific american link:

Naked Wii party?
This is quite old news, but here's a link with some scientific information: Diamond Thread.
So would my mom. The cancer had other ideas.
At least she's alive and doing well.
If you think I voted for Trump because of this post, you're wrong. I voted for Dr. Jill Stein of the Green Party. Again.
Nanothread and the Benzenes.

Hence the plural 'friends' ;)
But push come to shove, a C or a nice looking B will do just fine :D
time to start growing those diamond spaceships :P
