Comment on “Preparation and electrorheological property of rare earth modified amorphous BaxSr1−xTiO3 gel electrorheological fluid”

Organic/inorganic hybrid of polyaniline/BaTiO3 composites and their electrorheological and dielectric characteristics

“…(6) is believed to be very useful in constructing the master curve for ER fluids. In addition, note that the deviation of the E c do not change the scaled universal yield stress equation itself but the point moves following the universal yield stress equation, moving up for the higher E c and moving down for the lower E c 41…”

“…To better fit experimental data, a modified universal correlation introducing an additional parameter b was suggested for the systems that are partly discord with eq. (5) whereas the plots seem to follow an alternative curve 41. We rescaled $ \hat{\tau} $ with $ \hat{\hat{\tau}}=\hat{\tau}\hat{E}^{4b} $ and $ \hat{E} $ with $ \hat{\hat{E}}=\hat{E}^{1+2b} $ for the data, and derived a new equation as …”

Unveiling the Critical Role of Surface Oxidation of Electroresponsive Behaviors in Two-Dimensional Ti3C2Tx MXenes

“…As plotted in Figure g, both types of ER fluids show an alternative yield stress model, in which τ y is directly proportional to E 2 at a low electric field region, and approaches to 1.5 at a high electric field region. The cross-point of the electric field, which is called as the critical electric field ( E c ), was introduced to describe the derivation of the hybrid yield stress equation as follows …”

Pickering emulsion polymerized smart magnetic poly(methyl methacrylate)/Fe2O3 composite particles and their stimulus-response

“…The value of m is varies empirically from 1.0 to 2.0 depending on the different MR materials. 50,51 On a logarithmic graph, the experimental points of s y could be placed on a straight line with a slope of 1.0.…”
