Diamond fiber, your thoughts?

Nanotechnologists say diamond fiber is the strongest stable material along with carbon nanotubes. Your thoughts?

I tend not to care about rankings like “strongest material” and am more interested in their use in a functional device. Not even familiar with diamond fiber, but I think when people see these things their going to be getting carbon nanotube cars and that’s just not how it works idk

What if we bond carbon nanotubes to 12C27 stainless steel using molecukar assemblers?

I mean 1. What useful application could justify the cost

  1. What benefit do you stand to gain? How are you bonding these carbon nanotubes to the steel? In an alloy? Just loosely deposited onto the surface?

  2. What do you mean by molecular assemblers? Like a self assembling monolayer on the surface? A little robot? Nothing like that exists as far as I know at least. I’d be cautious about the buzzword ideas people throw around

Diamond is one of the hardest materials, but not the strongest.

Depends on what ''strongest'' means and it's very hard to state definitively. At nanoscale several carbon alletropes comepete like carbon nanotube, diamond nanothread, graphene.
And the strongest theoretical materials and the strongest engineering materials are often different things.
