Seriously Small Structures

Nanotube (c)

Seriously small structures are the focus of this week's Naked Scientists, as we look at nanostructures and their role in future energy technologies. We find out how nanostructures could hold the key to safe storage and retrieval of hydrogen fuel, and can help us to build better batteries. Also, how scientists have caught swine 'flu in the act of mutating, why females are more likely to suffer the effects of stress, and a way to weave bomb proof curtains that expand when they're stretched. Plus, in kitchen science, we find out why soap bubbles create such beautiful colours.

  • 11:33 - Creating Bomb-proof Curtains

    A new type of material, one that gets thicker rather than thinner when you stretch it, is being developed by EPSRC funded researchers and they're trying to provide better protection from the effects of bomb explosions. Jane Reck spoke to the inventors who are based at Exeter Un...

  • 19:13 - Storing Hydrogen safely

    With hydrogen tipped as the green fuel of the future, safer, more efficient methods of storage need to be found to make it possible. Stephen Bennington from ISIS at the Rutherford Appleton Laboratory is looking at how nanostructured materials could help...

  • 35:41 - Nanostructures in Batteries

    Lithium ion batteries are an essential part of most of our everyday lives. For each different job, you're looking at different properties whether itís fast-charging time, efficiency, safety, or cost. At the moment, thereís a trade-off between these properties, but nanotechnolo...

  • 41:47 - Bubble Colours - Interference Colours

    Make beautiful nanoscale structures using nothing more sophisticated than the washing up...

  • 50:03 - Is there Hydrogen on the Moon?

    Is there Hydrogen on the Moon?

  • 50:54 - How do we safely store hydrogen?

    A team of researchers from the University of Crete led by George Froudakis has designed a sponge-like material made of layers of one atom-thick graphene separated by carbon nanotubes 1.2-nanometers tall. The material contains positively-charged lithium ions that further strengthe...
