Desert Beetle: Help for the Drying Planet
Chemists from the NCU, due to their observations of the desert beetle which can both collect and repel water, wish to develop membranes able to transport water and retain salt as well as other contaminants more efficiently.
A number of scientists whose work is inspired by natural behavior is constantly growing. The lotus flower, with its ability to self- clean, is commonly described in literature and can be best examples the trend. Researchers started to wonder why the flower behaves in this manner and they decided to study its structure with the use of microscopes. Hence, they could draw the conclusion that the structure is highly hydrophobic, i.e. it maintains water drops on the surface. Water then collects particles of dust and by flowing down, removes them by flowing down. It means the adhesion forces, those responsible for accumulating water on the flower, are weak, but at the same time, dirt easily attaches to droplets, which result
