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-funded scientists are working to improve short-term forecasts for direct solar radiation and coming cloudiness. Reliable estimations will greatly benefit the solar energy sector, leading to decreased costs and massive deployment of renewable energy technologies.
