Soooo Close to Plasteel!

By mimicking a brick-and-mortar molecular structure found in seashells, University of Michigan researchers created a composite plastic that's as strong as steel but lighter and transparent.

It's made of layers of clay nanosheets and a water-soluble polymer that shares chemistry with white glue.

Engineering professor Nicholas Kotov almost dubbed it "plastic steel," but the new material isn't quite stretchy enough to earn that name. Nevertheless, he says its further development could lead to lighter, stronger armor for soldiers or police and their vehicles. It could also be used in microelectromechanical devices, microfluidics, biomedical sensors and valves and unmanned aircraft.


What happens we can make a real pasteel (ie plastic as strong in all ways as steel) as cheaply as any other plastic?

Will! I have a favor to ask!
Would you read through my latest mega-post, "Evolution for Dummies," and let me know what you think of it? I'm trying to build a lecture series around it for the Alaska Museum of Natural History, and I'd appreciate some feedback from my bestest blogger buddies. Thanks, brother.

And as durable?
