Amy Barnes, a National Science Foundation (NSF) fellow and graduate student in materials science, makes phosphorus-rich phosphate glass to use with her doctoral research work studying the interaction between microbes and minerals. Phosphate glass is different from the glass that's in windows and is built around sand or silica. Glass surfaces can substitute for mineral surfaces in experimental procedures.
