摘要：
软界面在自然界中普遍存在，支配着润滑、稳定性和物质输运等典型流体动力学功能。本文展示了磁性-非磁性流体界面处的磁力场如何形成具有非线性弹性和可调粘性剪切特性的超软界面。磁压力、粘性应力与拉普拉斯压力之间的平衡导致形成变形且稳定的液-液管状结构，其表观弹性在2 kPa至10 kPa范围内，并可通过适当选择液体性质进一步扩展。这种具有任意形状、粘性剪切几乎消失的高变形性液-液界面，为独特的微流控现象、生物材料流动和复杂生物系统模拟开辟了新的途径。
英文摘要：
Soft interfaces are ubiquitous in nature, governing quintessential hydrodynamics functions, like lubrication, stability and cargo transport. It is shown here how a magnetic force field at a magnetic-nonmagnetic fluid interface results in an ultra-soft interface with nonlinear elasticity and tunable viscous shear properties. The balance between magnetic pressure, viscous stress and Laplace pressure results in a deformed and stable liquid-in-liquid tube with apparent elasticity in the range 2 kPa -10 kPa, possibly extended by a proper choice of liquid properties. Such highly deformable liquid-liquid interfaces of arbitrary shape with vanishing viscous shear open doors to unique microfluidic phenomena, biomaterial flows and complex biosystems mimicking.
