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).
The EU is dedicated to reducing emissions associated with air transport. The objective applies equally to rotorcraft as to aeroplanes, so first-time measurements and models of helicopter flue gas emissions are of fundamental importance to the efforts.
