"two crystal structures within same material... replacing small fraction of manganese with copper produced complex microstructures with interconnected nanodomains, defects, and coherent interfaces... affected material's transport properties for electrons and heat... stable up to 400 degrees C... range within waste heat temperature range. He is convinced that, based on this discovery, cheaper novel and nontoxic thermoelectric materials could be designed to replace more problematic materials"
