The film—a water-absorbing, power-conducting hydrogel—is the most recent in a long line of discoveries to emerge from the Yu Research Group, a lab headed by Chinese-born chemist Guihua Yu.

In the researchers’ prototype device, a half-square-meter panel of the hydrogel is enclosed in a glass chamber coated with a ...

Hydrogel film could be equipped with great durability and high sensitivity as wearable sensors to track and distinguish human motions owing to electronic and ionic dual-conduction.

Hydrogel can be mixed into the local sandy soil, boosting water retention and nutrient distribution. Plants grown in the hydrogel membrane spread their roots throughout the top of the film.

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.

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 ...
