New 4D hydrogels — 3D materials that have the ability to change shape over time in response to stimuli — may lead to the development of human tissues, and even organs, that are more like their natural ...

With Valentine’s Day just two weeks away, science really is upping the stakes in exactly which flowers to buy your loved one on this Hallmark Holiday to show them how much you really care. First up, ...

3D printing has already transformed manufacturing, healthcare, engineering, and product development. Now, researchers are taking the concept a step further with 4D printing, a technology that allows ...

Combining materials with different swelling ratios creates structures that transform into tubes when exposed to water. (Courtesy: Yu Bin Lee) Materials that controllably change shape over time – often ...

Self-supervised learning needs no clean reference data; polymer tests reproduce earlier findings and reveal previously unanalyzed crystal components.

With 4D printing, the objects can change shape or properties using external stimuli such as temperature, light, pH, magnetic field, electricity, and moisture. Additionally, the changes in shape or ...
