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 ...

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 ...

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 from MIT recently made a groundbreaking discovery in the field of harvesting by producing a material with the ability to turn the air from even the most scorching environments into water.

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 ...

A hydrogel can cool off electronics and generate electricity from their waste heat. Scale bar, 2 cm. Courtesy: Adapted from Nano Letters 2020, DOI: 10.1021/acs.nanolett.0c00800 A new thermogalvanic ...
