Turning saltwater into tasty, drinkable H20 at desalination plants is probably the biggest-selling point of reverse osmosis, but let's back up a minute. What's osmosis, and why — and how — is reversing it useful to us?
Welcome to the wonderful and weird world of nanowires. Scientists can adapt this incredibly thin material for a number of uses, whether as a fiber-optic nanowire or to build increasingly smaller microprocessors. They're even used in medical implants.
Plastics can be shaped or molded into any form, and they're everywhere -- in your car, computer, toys and even bubble gum. But because they don't degrade, they cause big problems when it's time to throw them out.
Nanotechnology is one of the hot buzzwords of the 21st century. You know that it has to do with things that are very small, but just what are the implications of technology on the molecular scale, anyway?
If people could create nanomachines, they might be able to help fight diseases on the molecular level. They might even be able to replicate themselves. But what happens if that process gets out of hand?
This not-so-new material looks like a hologram and could play a valuable role in the future of insulation, electronics, oil spill cleanup and green energy. So why don't aerogels have the A-list name recognition they deserve?
Versatile and efficient, electroluminescent (EL) wire is widely used by artists to illuminate clothing, bicycle spokes, turntables and even cars. But how does this cool product work with so little power and without a visible energy source?
Nanotechnology is so new, no one is really sure what will come of it. Even so, predictions range from the ability to reproduce things like diamonds and food to the world being devoured by self-replicating nanorobots.
Dyneema is trademarked as the world's strongest fiber. Find out how this high-strength synthetic is capable of protecting an individual (or an entire vehicle) from IEDs or even shots fired from an AK47.
