Graphene Pores When water molecules (red and white) and sodium and chlorine ions (green and purple) encounter a sheet of graphene (pale blue, center) perforated by holes of the right size, the water passes through, but the sodium and chlorine of the salt are blocked. David Cohen-Tanugi/MIT

Graphene Sheets Can Be Turned Into the Best Filters Ever, For Desalination and Much More -- Popular Science

Add another item to the list of things one can accomplish using graphene, the wonder material of the future: Clean drinking water. Graphene could cheaply and easily remove salt from seawater, potentially turning the oceans into a vast drinking supply for thirsty populations. With properly sized holes, graphene sheets may be able to serve as all-purpose filters.
