By aligning carbon nanotubes inside polymer composites, Wardle and his colleagues designed electrodes that allow ions to travel more quickly between the tiny cylinders.

‘Express lanes’ for ions

By aligning carbon nanotubes in electrodes, researchers boost performance.

This filament containing about 30 million carbon nanotubes absorbs energy from the sun as photons and then re-emits photons of lower energy, creating the fluorescence seen here. The red regions indicate highest energy intensity, and green and blue are lower intensity.

Solar funnel

New antenna made of carbon nanotubes could make photovoltaic cells more efficient by concentrating solar energy.

MIT chemical engineers built tiny channels out of carbon nanotubes — hollow tubes whose walls are made of lattices of carbon atoms. Small particles such as sodium ions and protons can flow through the channels.

Pushing ions through carbon nanotubes

The tiny, multitalented carbon tubes can carry single molecules, one at a time.
