A substance that causes pollution by contaminating air, water, or soil?

The fabrication approach that builds products from the atomic or molecular level.

A new assembly approach that deposits layers one-atom-thick precisely onto a surface.

The fabrication approach that starts with large materials and trims them down to the nanoscale.
