Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
Increasing the thermal efficiency of fossil power plants is a promising way to decrease fuel consumption and emissions and minimise global climate change. A new steel alloy promises to do just that for major global benefits.
