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).
One of the main problems of the use of nuclear energy is nuclear waste management. An EU-funded project focuses on assessing the use of minor actinides from the used nuclear fuel as a fuel for next-generation nuclear reactors.
