Researchers developed a biodegradable sanitary pad using water hyacinth fibers and cotton, transforming an invasive aquatic ...

The Massachusetts Institute of Technology (MIT) Device Laboratory has developed a new material that boasts an unprecedented water absorption rate using natural water-absorbing materials and hydrogels.

Engineers find the hydrogel polyethylene glycol (PEG) doubles its water absorption as temperatures climb from 25 to 50 C, and could be useful for passive cooling or water harvesting in warm climates.

The vast majority of absorbent materials will lose their ability to retain water as temperatures rise. This is why our skin starts to sweat and why plants dry out in the heat. Even materials that are ...
