The first images that come to mind when one thinks of a tank are typically a top-mounted cannon, treads, and of most importance to those inside, armor. The concept of a mobile vehicle protected by ...

This schematic shows an engineered material with composite layers. Layers of carbon fibers (the long silver tubes) have microscopic forests of carbon nanotubes between them (the array of tiny brown ...

In an approach they call 'nanostitching,' engineers used carbon nanotubes to prevent cracking in multilayered composites. The advance could lead to next-generation airplanes and spacecraft. To save on ...
