Inside tiny tubes, water turns solid when it should be boiling

1nm carbon nanotubes... I doubt these can be produced at macroscopic scale.

Moreover the difference between 1.05 and 1.06 nm drastically affected freezing point. I don't think these can be built, en masse, to such precision.

Well, they wouldn't have to be made with precision provided there's an easy way to separate them. Which is still difficult but could be doable.

I think the author might have misread something. The Van der Waals radius of a carbon atom is only 0.17 nm, so the radius of a single tube can't vary in steps of 0.01 nm. Maybe this just referred to the average tube radius?

Hmm. A tube is composed of many carbon atoms in a ring. Add one more atom, you increase the circumference by 0.34nm but the radius only by 0.34/2pi=0.054nm. So still looks infeasible.

Perhaps at this time.
