Engineers have created a cooling hydrogel material that can convert excess heat from electronic devices into electricity. The thin hydrogel film, which is made up of a polymer and water, can draw heat ...

Coating the inside of glass microtubes with a polymer hydrogel material dramatically alters the way capillary forces draw water into the tiny structures, researchers have found. The discovery could ...

On the top floor of the University of Texas at Austin’s engineering building, students occasionally scribble notes as they quietly conduct experiments amid rows of cabinets packed with neatly labeled ...

With average summer precipitation of about 1 inch (2.5 centimeters), temperatures higher than 100 degrees Fahrenheit (38 degrees Celsius) and nutrient-poor sandy soil, it's easy to see why agriculture ...

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 ...

Researchers developed a low-cost gel film made of abundant materials that can pull drinkable water from the air in even the driest climates. More than a third of the world's population lives in ...
