Global population projections suggest that worldwide demand for water will increase by a third before 2030.
But with more than a billion people already experiencing drinking-water shortages, and with a potential 3-4 oC increase in temperature and subsequent redistribution of rainfall patterns, things are likely to get even worse.
CNTs – essentially sheets of one-atom thick carbon rolled into cylinders – have been investigated by Reese and his research group, using computer simulations, as a new way of addressing this challenge and transforming abundant seawater into pure, clean drinking water.
Water filtration may be one of the first important and practical uses for newly emerging nanotechnology. To read the rest of the article, click here.
