Lake County, California, is exploring a targeted strategy to fight harmful algal blooms on Clear Lake, one that pairs ...

Hydrogels are soft, water-rich polymeric materials that can swell or shrink in response to environmental stimuli. This ability to change shape makes them valuable in miniaturized devices for flexible ...

However, most current hydrogel pores use circular designs, which limit control over shape change and lead to unpredictable, slow actuation. They often close unevenly and recover poorly, reducing their ...

A gelatinous substance that would otherwise be waste from a nut often used to make herbal tea can be made into a hydrogel with all different biomedical uses, University of Chicago researchers recently ...

The proposed strategy utilizes facet-and-hinge architectures to guide the swelling of facets in polygonal pores along predefined directs, enabling precise control over pore closure and restoration.
