Hollow C nanotubules are formed under high shear within the thin film of a vortex fluidic device (VFD) without the need for using auxiliary reagents, high temperatures and pressures, and/or requiring downstream processing. This novel bottom-up crystallisation process involves intense micro mixing of two liquids (toluene solution of C and anti-solvent, isopropyl alcohol) within a thin film in the VFD to precisely control the hierarchical assembly of C molecules into hollow nanotubules. The mechanism of self-assembly was consistent with them being a mould of the high shear double helical topological flow from Faraday waves coupled with Coriolis forces generated within the thin film.
中空碳纳米管是在涡旋流体装置（VFD）的薄膜内通过高剪切力形成的，无需使用辅助试剂、高温高压，也不需要下游处理。这种新颖的自下而上的结晶过程涉及VFD中薄膜内两种液体（碳的甲苯溶液和反溶剂异丙醇）的强烈微混合，以精确控制碳分子分层组装成中空纳米管。自组装机制与它们作为由法拉第波产生的高剪切双螺旋拓扑流的模具一致，该流与薄膜内产生的科里奥利力相结合。
