Investigation of the Effect of High Shear Stress on Mesenchymal Stem Cells Using a Rotational Rheometer in a Small-Angle Cone–Plate Configuration [PDF]

open access: yesBioengineering
Within the healthy human body, cells reside within the physiological environment of a tissue compound. Here, they are subject to constant low levels of mechanical stress that can influence the growth and differentiation of the cells.

On the evaluation of yield stress of soils for debris flow analysis [PDF]

open access: yesE3S Web of Conferences, 2019
Debris flow materials behave as a fluid, hence its analysis requires rheological parameters such as yield stress and viscosity. Yield stress is associated to the start and the end of the mass movement downhill in the sense that it denotes the yield ...

Rheokinematics for product development—Formulation screening in rotational rheometers

open access: yesAIChE Journal, 2021
AbstractProduct formulations for industrial processes are typically developed at laboratory scale. However, the mixing conditions are not easily mimicked in the laboratory. A rotational device is proposed in this study as a fast laboratory‐scale formulation development, which enables mimicking the mixing conditions in the industrial process.

Use of helical ribbon mixer for measurement of rheological properties of fruit pulps

open access: yesCzech Journal of Food Sciences, 2001
Fruit pulps contain fine particles of the flesh of the original fruit that are suspended in the fruit juice. This suspension has a tendency to settling or separation during measurements of its rheological properties in the rotational rheometer with ...
