Maybe this is an easier way to produce them.
This process would create a VO2 nanotube–graphene hybrid.
I read VO2 tubes could also block heat, and could be interesting for window coatings.
You can buy VO2, but normal VO2 doesn't have the nanotube structure!
@ gerold, in the paper under methods they describe how to produce them (page 20).
You need a vacuum chamber and in…
Inside the VO2 tubes the saturation level is almost 100%, the paper does prove this.
The atoms are also aligned in a row.
According some theories how try to explain lenr, are this the perfect conditions.
I real hope someone has the equipment to…
This is also an interesting material to store atomic hydrogen/ deuterium!
Not yet commercial available and I don't have the equipment to make these tubes myself
