In addition, the absolute weight-average molecular weight and second virial coefficients of four polyethylene standards (three high density and one low density) were obtained using low-angle laser light scatter
Maximizing the natural frequency and harnessing them to certain target values were the key objective functions, and the fiber orientation angle and volume fraction along with the ply thickness distribution formed the design variables. With the aim of minimizing the compliance of FG beams and bridge ...
The first molecular weight to consider is thenumber averagemolecular weight (Mn¯). This average is like the averages you are probably already used to. The molecular weight (M) for each polymer in a sample is added, and the sum is divided by the total number of molecules counted. ...
To understand this contradiction, we conducted small-angle neutron and X-ray-scattering experiments using blends of deuterated polyethylene and hydrogenated polyethylene with various molecular weights drawn just below the melting temperature at three drawing rates. We found that more low molecular weight ...

Electronically reprogrammable photonic circuits based on phase-change chalcogenides present an avenue to resolve the von-Neumann bottleneck; however, implementation of such hybrid photonic–electronic processing has not achieved computational success. Here, we achieve this milestone by demonstrating an in-memo...
