WebApr 30, 2024 · Oscillatory shear stress (OSS) reduced the expression of GPR30 in human aortic endothelial cells (HAECs) in a time-dependent manner. HAECs were exposed to OSS (5 dyn/cm 2) for various periods of times (6, 12, 24 h). (A). Expression of GPR30 at the mRNA level; (B). Expression of GPR30 at the protein level (*, #, $, P<0.01 vs. previous … Web• The low shear results on several 5W-30 oils revealed some interesting behavior. The sheared or degraded oil had higher viscosity results than the fresh oil at 100 °C. Both the dynamic viscosity and the kinematic viscosity results showed the same trend. • This behavior of viscosity increase with shear was observed

Though the exact cause of shear thinning is not fully understood, it is widely regarded to be the effect of small structural changes within the fluid, such that microscale geometries within the fluid rearrange to facilitate shearing. In colloid systems, phase separation during flow leads to shear thinning. In polymer systems such as polymer melts and solutions, shear thinning is caused by the … WebHigh shear mixers are used to emulsify, homogenize, disperse, grind and/or dissolve …
WebShear thickening materials have found a choice place as smart shock absorbers. The apparent shear viscosity of these non-Newtonian fluids increases with increasing shear rate (Fig. 22.4 ): under static deformation, the material will flow while it becomes solid when shear stress is applied at high rate. WebJan 30, 2024 · Soft, flexible materials tend to have low shear modulus values. Alkaline earth and basic metals have intermediate values. Transition metals and alloys have high values. Diamond, a hard and stiff substance, has an extremely high shear modulus. Note that the values for Young's modulus follow a similar trend.
