English

Noun

microviscosity ‎(plural microviscosities)

1. The friction experienced by a single particle undergoing diffusion because of its interaction with its environment at the micrometer length scale.
   • Both the crowding density and relative size of each co-solute in a mixture will contribute to the measured microviscosity as assessed by altered translational mobility. ^[1]
   • The friction experienced by a single particle can be thought of as a microscopic viscosity (microviscosity) and should not necessarily agree with the bulk viscosity since it is a measure of the probe's local friction whereas bulk viscosity analogously would be the measure of an infinitely large probe. "Aron Benjamin Goins" ^[2]

Synonyms

• microscopic viscosity
