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 gel material is cheap to make, and a single kilogram can produce liters of water in seemingly dry conditions. Reading time 4 minutes As the world becomes increasingly hot, fresh and clean water is ...

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 ...

Tom Sellars, CEO: “Sellars is one of two manufacturers with proprietary technology that makes the best overall performing wipes and towels. We’re the only company capable of making high-performance ...

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 ...
