Semicrystalline polymers are known to have a rigid amorphous fraction (RAF), which is present at the interface of the amorphous phase and crystal due to the immobilization of a polymer chain caused by ...

The structure of semi-crystalline polymers largely depends on how strongly their molecular chains are entangled. Following numerous experiments, researchers developed a new model to predict the ...

Amorphous materials, broadly defined as condensed matter without crystalline structures, have become subjects of increasing interest in the twenty-first century. Philip W. Anderson once observed that ...

Photocatalysis, a technology that converts solar energy into chemical reactions, holds immense promise for addressing energy shortages and environmental pollution. However, traditional crystalline ...

Intrinsic structure of amorphous polymers is highly disorder with long molecular chains entangled with each other. They are usually considered as thermal insulator due to their ultra-low thermal ...

Conductive organic materials often derive their electronic properties from highly organized crystal structures. Now, researchers have developed an organic polymer that conducts electricity like a ...

This series of articles is designed to help molders understand how a few analytical tools can help diagnose a part failure problem. Michael Sepe is our analyst and author. He is the technical director ...

A polymer is a chemical compound that contains a large number of identical molecular repeating units. A plastic material is a polymer, typically modified with additives, which can be molded or shaped ...

The use of plastics materials has increased dramatically throughout the world over the past 50 years, and now stands at roughly 100 billion pounds. Commercial plastics are known as resins in North ...

Engel and Heraeus have reduced cycle times by up to 70 percent compared with previous production solutions for the injection molding of amorphous metals. In doing so, the two system partners have ...
