  1. Nontoxic Nanosheets Could Turn Waste Heat into Power Joel D. Brock, Cornell University, DMR 0936384 Broader Impacts: Two-dimensional (2D) oxide crystals present exciting opportunities for new scientific and technological breakthroughs with their novel electronic, ferromagnetic, magneto-optical, electrochemical, catalytic, and photoresponsive properties. One of the most exciting new applications for metal oxides is thermoelectrics. Thermoelectric oxides are chemically and thermally stable. They can be composed of nontoxic, light, cheap, and naturally abundant elements. They can be produced through environmentally friendly means, and are expected to play a vital role in extensive applications for waste heat recovery under atmospheric conditions.
