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).
An EU-funded study of vortices, waves and mixing processes in idealised models has provided a greater understanding of mechanisms behind weather patterns, climate and other natural processes.
