我们提出了一种稳健的方法来创建具有可控壳厚度的多重乳液，该壳厚度可以在很宽的范围内变化。我们使用微流体装置来产生不混溶流体的同轴射流;使用滴落不稳定性，我们将射流分解成多重乳液。通过控制每层射流的厚度，我们调节了多重乳液的壳层厚度。相同的方法在由不能以其它方式可控乳化的流体（例如粘弹性流体）产生单分散乳液中也是有效的。
We present a robust way to create multiple emulsions with controllable shell thicknesses that can vary over a wide range. We use a microfluidic device to create a coaxial jet of immiscible fluids; using a dripping instability, we break the jet into multiple emulsions. By controlling the thickness of each layer of the jet, we adjust the thicknesses of the shells of the multiple emulsions. The same method is also effective in creating monodisperse emulsions from fluids that cannot otherwise be controllably emulsified, such as, for example, viscoelastic fluids.
