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.

A team of international researchers discovered a new hydrogel material that can increase water absorption from dry desert air, which could reduce water scarcity in arid regions. With global ...

A team of researchers has invented a novel gel-like material that not only effectively dehumidifies ambient air to improve thermal comfort, but it also harnesses the moisture in the air for a wide ...

Researchers have created a superabsorbent hydrogel that can pull moisture from the air in greater quantities than previously reported materials, even in desert conditions. The new material opens the ...

Scientists from Tomsk Polytechnic University, together with colleagues from the University of Bravijaya (Indonesia), have developed a hydrogel based on food waste for water purification from heavy ...

In many arid coastal regions, a great quantity of valuable fresh water is lost into the atmosphere every day, as it evaporates from the surface of the ocean. This situation prompted scientists to ...

In the early 2010s, researchers from the School of Chemical Engineering at the University of Campinas (FEQ-UNICAMP) found that as the proportion of biodiesel mixed with fossil-originated diesel ...

Using solar power and what they refer to "super sponges," a team of engineers at the University of Texas at Austin have developed a neat, and potentially life-saving, magic trick: pulling water out of ...
