Low-Temperature Material Synthesis

Nano-Fermentation

What is it?

Nano-FermentationA novel nanofermentation process that biologically converts solvents (precursors) to nanoparticles. Precursors and bacteria control the particle characteristics for a wide range of materials from CIGS to powder metals.

Why is it Important

  • A very scalable and low cost/low energy process for the production of a wide range of nano-particle materials
  • A 50,000 gal fermentor provides 500k g/month of nano-particle materials
  • Environmentally friendly process of no wasted materials

What is the Status?

  • Large quantities of CIGS have been fermented at ORNL
  • Providing materials for Additive Manufacturing processes for products such as thin film photovoltaics from CIGS
