Climbing Colloidal Suspension

Mixtures of powder and liquid are ubiquitous in nature as well industries exhibit complex flowing deforming behaviors, including sol to gel transition under shear stress. In order better understand the characteristic features this type mixture, we observed behavior a mixture colloidal silica particles water model system vibration. The showed different states, from powder-like viscous fluid-like, with increasing content water. At certain concentrations (around 70 wt. %) relatively faster vibration (over 17 Hz), that suspension climbed up wall container against gravity. main purpose paper is report how can observe climbing silica. rheological measurements demonstrated shear-thickening behavior, where force chain networks normal stress differences considered develop. Therefore, speculate transient formation breaking contribute occurrence suspension. tunable suspensions may help elucidate mechanism future.
