A memorandum of understanding between PNNL and the University of Oregon will focus initially on materials science.

An enzyme called nitrogenase works each symmetrical half in turn to produce ammonia efficiently.

PNNL's self-powered fish-tracking tag uses a flexible strip containing piezoelectric materials to emit tiny beeps that are recorded by underwater receivers. The device is designed for long-living fish such as sturgeon, eels and lamprey.

There is a science website for kids that defines materials science as "the study of stuff" and, in the simplest of terms, that's right.
