The viscosity of a shear thickening fluid, or dilatant fluid, appears to increase when the shear rate increases. Corn starch suspended in water ("oobleck", see below) is a common example: when stirred slowly it looks milky, when stirred vigorously it feels like a very viscous liquid. A familiar example of the opposite, a shear thinning fluid, or pseudoplastic flui… WebNov 9, 2024 · Bingham plastic fluid medium has a higher viscosity and yield stress than normal media, which might prevent the mixing of the culture medium and limit the transportation of substrate and oxygen. Generally, pluripotent stem cells generate their energy via glycolysis, which does not require oxygen, so their oxygen requirement is low.
