A new study led by Colorado State University Distinguished Professor Eugene Chen outlines a path to creating advanced, recyclable plastics. Published in Nature, the study describes a breakthrough ...

In a win for chemistry, inventors have designed a closed-loop path for synthesizing an exceptionally tough carbon-fiber-reinforced polymer and later recovering all of its starting materials. In a win ...

Extensional flows dominate many polymer processes, including blow molding, film blowing, fiber spinning, thermoforming and many others. The rheology of polymeric materials under extensional flows can ...
