Some of the factors that comprise the preferred viscous behavior of a cosmetic sample are flowability, processability, stiffness, and consistency. As such, they are essential parameters for quality ...

Traditional methods for measuring IV of hygroscopic polymers involve dissolving the polymer in halogenated solvents such as chlorinated phenols and comparing the flow time of the solution with that of ...

With their identification of negative velocity, scientists have made a physics-defying discovery about how cells move.

The cells in our bodies move in groups during biological processes such as wound healing and tissue development—but because of resistance, or viscosity, those cells can't just neatly glide past each ...
