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).
Researchers have shown for the first time how Arctic rivers are transporting vast quantities of organic carbon into the oceans. This process occurs as the permafrost melts, which is due to climate change.
