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.

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 ...

(Nanowerk News) Huge amounts of water evaporate from water surfaces such as reservoirs and the open sea each day. To address this issue, especially in water scarce areas, researchers from the National ...

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 ...

Engineers synthesized a superabsorbent material that can soak up a record amount of moisture from the air, even in desert-like conditions. MIT engineers have synthesized a superabsorbent material that ...

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 ...
