Nanotubes

It Slices! It Dices! Nanotube Struts Its Stuff, writes the NYTimes:

It is stronger than steel and far sharper than a pin. It shoots electrons and draws away heat. It can become the thinnest of wires and, potentially, electronic devices almost as minuscule as molecules.

In the last decade, the cylindrical molecule of carbon known as a nanotube has become a do-all wonder substance, touted for future use in everything from X-ray machines to paint. Nanotubes are already sprinkled in more than half of lithium ion batteries: their ability to carry electricity hastens recharging, and they act like tiny springs to hold apart the sheets of graphite in the battery, extending its lifetime.
