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.

    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.

  6. Need a Synthesis Process by Anonymous Coward · · Score: 2, Insightful

    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).

      Even in unique yet known products development can take years. There is a kickstarted for an eink gps device with a seven inch screen and a solar pane on its back. It is currently 18 months behind original schedule. Primarily because product testing and certifications were a lot harder to deal with than they realized.

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.

      Now, if one were to have a handle from which sprang an end-disc by a telescoping rod, and attached to the circumference of that disc, and extending back down to the handle, were these insanely-sharp nano-threads, heated possibly by electricity akin to an everyday electrical heating element, or by the energy of the ultrasound energy itself such that it appeared like a column of glowing light growing out from the handle, you'd have a good approximation of a Light Saber.

      Heck, the slight differences in the precise frequency each thread would be vibrating at would likely cause relatively-low frequency harmonic notes equal to the difference in frequency between each thread. You would have the humming and slight frequency & phase shifts produced by light sabers being swung around.

      Wish I had the resources to throw at the problem. Heck, even if it didn't turn out to be exactly a "light saber", an ultrasonic nano-thread sword that could slice through heavy armor like butter would be awesome, not to mention all the practical industrial and medical potential such a tool would posses.
