That's exactly what a group of chemical engineers and biochemists attempted in a new study, embedding single - walled carbon nanotubes — microscopic tubes thinner than a human hair that can also absorb sunlight and convert it to electron flow — in living chloroplasts.

The models showed that thinner carbon nanotubes with a relatively high concentration of nitrogen would perform best, as oxygen atoms readily bond to the carbon atom nearest the nitrogen.

When Barron and his team began combining carbons and amines several years ago, they noticed an interesting progression: Flat graphene absorbed carbon dioxide well, multiwalled nanotubes absorbed it better, and thinner single - walled nanotubes even better.

He works with graphene, a stronger - than - steel infinitesimally thin lattice of tightly packed carbon atoms, and carbon nanotubes — sheets of graphene rolled into hollow tubes with walls that are just one atom thick.

A better alternative would be thinner, softer electrodes such as carbon nanotubes, a thousandth of the diameter of regular wires.

On carbon nanotubes, which are essentially only surface materials because of their exceptionally thin walls, the particle significantly changes the material's total electrical conductance.

When the material dried out, the silk was coated with a thin layer of nanotubes.

Carbon nanotubes, for example, are tens of thousands of times thinner than a human hair, yet are stronger than steel on an ounce - per - ounce basis.
