Fast-scanning atomic force microscopy imaging of the molecule at two different time points shows positional shifts along the polymer chain on the left. On the right, the molecular structure of PEG ...

Researchers overcame the tradeoff between plastic toughness and degradability by developing plastics with movable crosslinks. The crosslinks both increased toughness by over eight times and increased ...

Imagine a microscopic locomotive moving back and forth along a track, propelling itself without any external force. At the molecular level, this concept forms the foundation of molecular motors -- ...

Conceptual figure showing the enzymatically sustainable resources of poly(ε-caprolactone)-poly(urethane) (PCL-PU) with movable cross-links catalyzed by lipase as the enzyme. Osaka, Japan—Achieving a ...
