SYNTHETIC BIODEGRADABLE POLYMERS AS ULTRASOUND CONTRAST AGENTS
关键字：SYNTHETIC,BIODEGRADABLE,POLYMERS,ULTRASOUND,CONTRAST,AGENTS,
Ultrasound (US) imaging is now used more and more widely in clinical diagnosis because it can provide noninvasive, real-time cross-sectional images of tissues or blood flow. But it has a main problem that the signal discrimin...

OPTICAL RHEOLOGY OF AMORPHOUS POLYMERS IN JEFFREY-HAMEL FLOWS
关键字：OPTICAL,RHEOLOGY,AMORPHOUS,POLYMERS,JEFFREY,HAMEL,FLOWS,
Polymeric macromolecules exhibit isotropic behavior at rest when they are randomly distributed. However, flow deformation causes orientation of the macromolecules leading to anisotropy in the transport properties.
