The properties of semi-crystalline polymers largely depend on two factors: the thicknesses of the above mentioned layers and how strongly the chains in the amorphous regions are entangled. According ...

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

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 ...

These 'polymer alloy' composition changes have enabled the creation of materials with optimized toughness, processability, chemical resistance, and cost structures. Polymer blends and polymer alloys ...

Starting with billions of molecules of monomer in a reactor, heat and pressure are applied in the presence of catalysts, causing one of the monomer double bonds to rearrange into two "half-bonds," one ...

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 ...

The preparation of dense Si 3 N 4-based ceramics has attracted great attention due to the achievable improvements in mechanical properties and high-temperature oxidation resistance. In general, the ...
