Although water’s shear viscosity is important in accurate molecular dynamics modeling, the results from two popular water models differ from those of actual experiments by as much as 20%. In a recent ...

This study evaluates the shear-thinning effects of a commercial Viscosity Index (VI) improver in a variety of mineral oil base stocks to produce a series of viscosity grades from 0W-20 to 20W-50. All ...

Water is one of the most abundant substances on Earth and partakes in countless biological, chemical, and ecological processes. Thus, understanding its behavior and properties is essential in a wide ...

Models that inform how magma moves and volcanic eruptions unfold may need an update, according to a new study. It reports that gas bubbles in magmas can form through the mechanical forces of shear as ...

Suspensions may be acceptably stable to sedimentation for two reasons. Either the bulk material has a yield stress high enough to hold the particles in suspension, or the material has a ‘zero shear ...

Shear viscosity measurements were made as a function of temperature near the critical point and critical concentration for the binary system of nitrobenzene and n-heptane. The results above the ...

Flow curve in order to determine the plateau value of the vis­cosity performing a shear rate controlled flow curve at low enough shear rates in steady state.. The standard tests for measuring the Zero ...

Models that inform how magma moves and volcanic eruptions unfold may need an update, according to a new study. It reports that gas bubbles in magmas ...

A new low-shear-rate version of the ViSmart viscosity sensor instantaneously measures samples of low-to mid-range viscosity fluid. The sensor provides continuous, real-time, in-line viscosity ...
