Seriously Small Structures
|
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.

Scientists monitoring pigs in Hong Kong have spotted human H1N1 swine flu rearranging its genes.
Research has shown that one of the deadliest strains of malaria travelled with early humans as they left Africa and colonised Asia...
Scientists have found a way to use gene therapy to combat HIV infection.
Researchers in Philadelphia have found that there is a difference at the molecular level between how male and female brains deal with a particular stress hormone, which could explain why women are more prone to stress or anxiety related illnesses like post traumatic stress disor...
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...
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...
We all know what happens to water when it freezes - it becomes ice. But it does some weird stuff as well, and there are still lots of unknowns about how this sort of transition from water to ice actually happens, especially on the nano scale. Understanding this could help with ...
How much pressure did steam locomotives work under?
Lithium ion batteries are an essential part of most of our everyday lives. For each different job, you're looking at different properties whether it’s fast-charging time, efficiency, safety, or cost. At the moment, there’s a trade-off between these properties, but nanotechnolo...
Make beautiful nanoscale structures using nothing more sophisticated than the washing up...
What is spintronics, and how might it be involved with nanotechnology?
Quick question, assume in the future all cars are run on hydrogen. The only biproduct is water. I'm guessing the oxogen from the water comes from the atmosphere. Will this upset the balance?

Is there Hydrogen on the Moon?
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...
A light has to interact with our tissue for us to see it. Is it true that women have a variant of the pigment to see in the red spectrum?
Why can't dogs watch CRT-style TVs? Can they see the images on LCD and LED TVs?
A new type of blast-proof curtain that gets thicker, not thinner, when stretched is being developed to provide better protection from the effects of bomb explosions.
