Online viscometers measure the internal viscosity of polymers, proteins, and peptides that are coupled with GPC to characterize essential physico-chemical properties, such as the distribution of molar ...

Viscosity, a measure of a liquid’s fluidity, is measured through a substance’s resistance to motion under an applied force. Viscosity is also known as a fluid’s thickness. It is calculated by dividing ...

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 ...
