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).
Harvesting the Sun's virtually limitless supply of energy is an incredibly sustainable way to reduce dependence on combustion of fossil fuels. Novel technologies developed with EU funding promise to enhance widespread market uptake.
