High shear rate propulsion of acoustic microrobots in complex biological fluids. [PDF]
Sci Adv, 2022 Untethered microrobots offer a great promise for localized targeted therapy in hard-to-access spaces in our body. Despite recent advancements, most microrobot propulsion capabilities have been limited to homogenous Newtonian fluids.

Role of high shear rate in thrombosis. [PDF]
Journal of Vascular Surgery, 2015 Acute arterial occlusions occur in high shear rate hemodynamic conditions. Arterial thrombi are platelet-rich when examined histologically compared with red blood cells in venous thrombi. Prior studies of platelet biology were not capable of accounting for the rapid kinetics and bond strengths necessary to produce occlusive thrombus under these ...

Leukocyte margination at arteriole shear rate [PDF]
Physiological Reports, 2014 We numerically investigated margination of leukocytes at arteriole shear rate in straight circular channels with diameters ranging from 10 to 22 μm. Our results demonstrated that passing motion of RBCs effectively induces leukocyte margination not only ...

Viscosity of Liquids at High Rates of Shear [PDF]
Nature, 1950 WHILE it is well established that solutions of macro-molecular substances may show an anomalous fall in the coefficient of viscosity at high rates of shear, there is much conflict in the experimental evidence relating to the behaviour in this respect of ordinary lubricating oils.

Roles of solution concentration and shear rate in the shear-induced crystallization of P3HT. [PDF]
RSC Adv, 2021 The shear temperature and solution concentration determine the FIP content. Increasing FIPs can accelerate the crystallization kinetics and change the crystallization mechanism from a second-order to a first-order reaction.

The impact of blood shear rate on arterial thrombus formation. [PDF]
Future Sci OA, 2015 The shear rate and corresponding shear stress have impacts on arterial thrombus formation. In particular, the effects of increasing concentration of platelets at the vessel wall and activation of platelets at this site increase the growth and stability ...

Effect of over-consolidation and shear rate on the residual strength of soils of silty sand in the Three Gorges Reservoir. [PDF]
Sci Rep, 2017 Estimation of the residual strength of the soil on the landslide sliding surface is essential for analyzing reactivated landslides. This study investigated the influence of over-consolidation ratio (OCR) and shear rate on the residual strength of SM-type

Transient dynamics in dense colloidal suspensions under shear: shear rate dependence [PDF]
Journal of Physics: Condensed Matter, 2012 A combination of confocal microscopy and rheology experiments, Brownian dynamics (BD) and molecular dynamics (MD) simulations and mode coupling theory (MCT) have been applied in order to investigate the effect of shear rate on the transient dynamics and stress-strain relations in supercooled and glassy systems under shear.

Influence of shear rate on the soil's shear strength
Environmental engineering, 2021 One of the most important mechanical properties is shear strength. It is conditioned by the value of the maximum shear stress that the soil can withstand before failure. Exceeding the shear strength causes one particle to slide next to another, causing the failure of soil.
