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).
How water interacts with different elements around it, such as soil, ice and structures, can reveal much about evolving climate patterns and help find ways to address global warming.
