We report an extensive study of the properties of carbyne using
first-principles calculations. We investigate carbyne’s mechanical
response to tension, bending, and torsion deformations. Under tension,
carbyne is about twice as stiff as the stiffest known materials and has an
unrivaled specific strength of up to 7.5×10^7 N∙m/kg, requiring a force of
~10 nN to break a single atomic chain.

Re: Carbyne from first principles
Fascinating. I had never heard of this before, which is odd given how much reading I've done on nanotubes and graphene.

I think this is new in the wild.
Looks promising.

Re: Carbyne from first principles
Ultra-Long, One-Dimensional Carbon Chains are Synthesized for the First Time
"Researchers involved in an international study, in which the UPV/EHU-University of the Basque Country has participated, have stabilised chains of more than 6,400 carbon atoms using double-walled nanotubes.
In a study, in which researchers in the UPV/EHU's Nano-Bio Spectroscopy Group led by Ángel Rubio have participated, a new route has been developed to produce carbyne (infinitely long carbon chains whose mechanical properties surpass those of diamond and graphene) by using double-walled carbon nanotubes to protect the carbon chain due to its extreme instability in ambient conditions. The results of the study have been published in the journal Nature Materials."
With a short description of confirmation techniques and a very short paragraph about applications.
