论文摘要
热力学平衡中的纯液体在结构上是均匀的。在液晶中，流动脉冲和光脉冲用于创建具有极性的可重构域。此外，通过仔细的工程工程，对局部的微流动流和局部光 - 热场，可以完全控制此类域的成核，生长和形状。实验，理论和模拟表明，只要液体保持在受控的非平衡状态，就可以无限期地稳定所得的结构。所得的雕刻液体可以在微流体设备中找到应用，以选择性地封装溶质和颗粒与与外部刺激相互作用的光学活性隔室。
Pure liquids in thermodynamic equilibrium are structurally homogeneous. In liquid crystals, flow and light pulses are used to create reconfigurable domains with polar order. Moreover, through careful engineering of concerted microfluidic flows and localized opto-thermal fields, it is possible to achieve complete control over the nucleation, growth, and shape of such domains. Experiments, theory, and simulations indicate that the resulting structures can be stabilized indefinitely, provided the liquids are maintained in a controlled non-equilibrium state. The resulting sculpted liquids could find applications in microfluidic devices for selective encapsulation of solutes and particles into optically active compartments that interact with external stimuli.
