Sedimentation of Suspensions in Shear-Thinning Fluids [PDF]

Oil & Gas Science and Technology, 2004
We present an experimental study of the sedimentation of non-Brownian monodisperse suspensions in polymeric shear-thinning fluids. In such media and contrary to what is observed in Newtonian fluids, no sedimentation front appears; particle aggregation moreover leads to the formation of vertical particle-rich structures and of an inhomogeneous particle ...

Ionic‐Electronic Hydrogel‐Liquid Metal Composite Bilayer with Tissue‐Adaptive and Adhesive Properties for Closed‐Loop Neuroprosthetic System

Advanced Functional Materials, EarlyView.
A hydrogel–liquid metal composite peripheral nerve interface (HLB‐PNI) combines electrically durable electrodes and tissue‐adhesive hydrogel for tissue‐adaptive implantation. In nerve‐injured rats, it enables the diagnosis of sensory‐motor connectivity via stimulation and neural signal recording.

The Hidden Internal Flow Dynamics of Shear‐Thinning Magma in Dikes

AGU Advances
The viscosity of magma has a first‐order control on the explosivity and hazards of a volcanic eruption, and the detection of diking within the subsurface may indicate an eruption is imminent.

Capillarity driven spreading of circular drops of shear-thinning fluid

, 2004
We investigate the spreading of thin, circular liquid drops of power-law rheology. We derive the equation of motion using the thin film approximation, construct source-type similarity solutions and compute the spreading rate, aparent contact angles and ...
