In the case of semidilute solutions, chains overlap and are to a certain extent entangled, meaning that a coherent filament is obtained with a low entanglement density, providing an optimum structure for ultradrawing. On the other hand, in the hypothetical case of melt-spinning the high ...
is viewed as the sum of weighted responses of diffusivity of all possible components, the ratio of cation diffusivity to anion diffusivity, D+/D−, in a specified IL affords the physical meaning: relative association degrees observed by anion-containing components to cation-containing components. ...

Surface molecular information acquired in situ from a catalytic process can greatly promote the rational design of highly efficient catalysts by revealing structure-activity relationships and reaction mechanisms. Raman spectroscopy can provide this rich structural information, but normal Raman is not sensitive...
