This multi-faceted situation has led to questions about size distribution and composition along with inquiries into how bulk properties of plastics change in the ocean9,10,11. Consequently, a large amount of data on physical (i.e., density, surface roughness, weight loss over time), thermal ...

McKeen Chapter Chemical enhanced oil recovery 4.2.3.1 Molecular weight Molecular weight is the main factor that affects the flow behavior of polymers. In general, the polymer with a higher molecular weight has a larger ...
Molecular weight of the polymers that are used in engineering plastics affects many of the plastics properties. While it is not always known exactly what the molecular weights are, as mentioned above higher flowing plastics of a given series of products generally are lower molecular weight polymers...
Broadly, plastics can be categorized as being semicrystalline or amorphous. Understanding the implications of the structure, and specifically, the crystallinity, is important as it affects material selection, part design, processing and the ultimate anticipated service properties. Most non-polymeric ...
Despite some studies producing partial results, there has been inadequate research into the chemical composition, sources, and formation mechanisms of OA. The primary reason for this difference was the substantial variation in the physicochemical properties of OA, including its functional group composition...

Molecular doping is a crucial tool for controlling the charge-carrier concentration in organic semiconductors. Each dopant molecule is commonly thought to give rise to only one polaron, leading to a maximum of one donor:acceptor charge-transfer complex and hence an ionization efficiency of 100%. Ho...
