A new breakthrough brings semiconductors made of wood closer to reality - Interesting Engineering

A new method of carbonization transforms cellulose derived from wood into a form of nanopaper with electrical properties and many types of useful 3D structures.

The idea of making semiconductors from wood isn't as far-out as it sounds. That's because cell walls in plants are made of a material called cellulose, and cellulose can be made to conduct electricit… [+3305 chars]
