我们报告了一种产生直径在微米/纳米尺寸范围内的不混溶液体的稳定同轴射流的方法。这种复合射流是由电流体动力（EHD）力的作用产生的，直径范围从几十纳米到几十微米。最终的射流破裂产生单分散化合物液滴的气溶胶，外部液体包围或封装内部液体。按照这种方法，我们生产了直径在 10 至 0.15 微米之间变化的单分散胶囊，具体取决于运行参数。
We report a method to generate steady coaxial jets of immiscible liquids with diameters in the range of micrometer/nanometer size. This compound jet is generated by the action of electro-hydrodynamic (EHD) forces with a diameter that ranges from tens of nanometers to tens of micrometers. The eventual jet breakup results in an aerosol of monodisperse compound droplets with the outer liquid surrounding or encapsulating the inner one. Following this approach, we have produced monodisperse capsules with diameters varying between 10 and 0.15 micrometers, depending on the running parameters.
