论文摘要
通过使用总润湿边界条件增强液体相对于表面的相互作用能量，液体对机械剪切应力的响应更强，并且在亚毫米尺度弹性特性下表现出。这项研究在这里扩展到具有强烈静电相互作用的液体，例如离子液体和顺磁性液体。我们表明，还可以在亚毫米尺度上识别和测量非零的低频剪切弹性。在液体中观察到的介质弹性特性通常被认为是粘离任何相位过渡的粘性，并且没有扩展的结构，这证实了将弹性相互作用视为在外部电场或磁场下将弹性相互作用视为有助于集体效应的相关性。
By reinforcing the interaction energy of the liquid with respect to the surface using total wetting boundary conditions, the response of liquids to mechanical shear stress is stronger and exhibits at sub-millimeter scale elastic properties. This study extends here to liquids with strong electrostatic interactions such as ionic liquids and paramagnetic liquids. We show that it is also possible to identify and measure a non-zero low-frequency shear elasticity at sub-millimeter scale. The observation of mesoscopic elastic properties in liquids generally considered as viscous away from any phase transition and the absence of extended structuring confirm the relevance of considering elastic interactions as contributing to collective effects under external electric or magnetic field.
