长圆柱体中的单分散泡沫具有有序的螺旋结构。我们已经制造了这种铁磁流体泡沫,并发现它们可以通过外部磁场以各种方式进行操纵。影响包括气泡形成过程中的形态变化、结构扭曲和尺寸控制。这提供了一种有前途的技术,用于在流体网络中有效地传输、切换和组合样品,可能在微流体规模上。
Monodisperse foams in long cylinders exhibit ordered spiral structures. We have made ferrofluid foams of this kind and find that they can be manipulated in a variety of ways by an external magnetic field. Effects include morphological changes, twisting of structures and size control in the bubble formation process. This offers a promising technique for the efficient transport, switching and combining of samples in fluidic networks, possibly on the microfluidic scale.
