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).
EU researchers successfully designed an innovative system for storing concentrated solar thermal energy. The developed reactor concept promises to make a real contribution to the EU's ambitious energy and climate change targets.
