"From the Ted Talk by Angela Belcher: Using nature to grow batteries"

Unscramble the Blue Letters

I thought I'd talk a little bit about how nature makes materials. I brought along with me an abalone shell. This abalone shell is a biocomposite material that's 98 percent by mass calcium carbonate and two pnrceet by mass protein. Yet, it's 3,000 tmeis tougher than its gciagooell counterpart. And a lot of people might use structures like abalone shells, like chalk. I've been fascinated by how nature makes materials, and there's a lot of sceerts to how they do such an exquisite job. Part of it is that these materials are miaropcocsc in structure, but they're formed at the nano scale. They're formed at the nano scale, and they use pteoirns that are coded by the genetic level that allow them to build these really etqxusiie structures.

Part of it is that these materials are macroscopic in structure, but they're formed at the nano scale.
