Nanotechnology against climate change
History has shown, yes, that new methods and steps are needed to find solutions to big problems. Nanotechnology can also be a great contributor to reducing the effects of climate change.
If new energy sources are used, for example, the emissions of gases that cause global warming - such as CO2 - can be reduced. Examples are fuel cells and next-generation solar cells, whose structure is based on nanoparticles and nanoporous materials.
On a planet where drinking water is an increasingly limited resource, water treatment and purification are essential. Technologies based on nanofiltration contribute significantly to this, as does the improvement of safety and quality methods through nanosensors. In addition, there are several proposals for the use of nanoparticles and nanoporous systems to collect carbon dioxide and other contagious molecules.
Nanotechnology could also be useful for improving agricultural production, such as pest control and food packaging and preservation.
In addition, new materials for construction and automotive are being created using carbon nanotubes. Lighter vehicles and aircraft are thus made and, as a result, fuel consumption is reduced and thus the emission of polluting gases is reduced.
