GD Second Timers: Bones 3 (A-D)

We use carbon nano-fibers to make some tennis rackets, baseball bats and bike frames.

Carbon nano-fibers also can be woven into clothes to provide a steady heat supply for the person wearing them.

There is a big effort to learn ways to keep the carbon nanofibers different thicknesses and to have them grow sideways to each other.

The 300 nm x 1.5 nm collagen molecule is astonishing! It’s 50-100 times as strong as steel.

Collagen proteins are parallel in parts of bone.
