The widely known principle of rotational viscometers is utilized for calculating the viscosity in most laboratory viscometers, by sensing the torque required for rotating a spindle at a constant speed ...

This article explores viscosity, covering definitions, measurement considerations, viscometer selection, and the symbiotic relationship between viscosity and rheology. The critical elements to ...

At a nanometre scale, the behaviour of biological fluids is largely governed by interfacial physical chemistry. This may manifest as slowed or anomalous diffusion. Here we describe how measures ...
