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 ...

Polymers are a popular material for everyday objects and have many industrial applications, with their use increasing rapidly. However, for new polymers to be developed and commercialized is often a ...

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 ...
