一些细菌以螺旋运动的方式移动，遇到来自周围水的阻力较小。在RNA聚合酶转位过程中也考虑了螺旋运动，已经观察到水和蛋白质的螺旋运动。我们发现，限制在金属有机骨架MIL-47中的苯分子以螺旋形的方式运动。这种壮观的扩散效应可以通过结合实验和计算工具来证明；两种实验技术，准弹性中子散射和氢核磁共振，覆盖了广泛的时间范围。
Some bacteria move with a corkscrew motion, meeting less resistance from surrounding water. A spiral movement is also considered during RNA polymerase translocation and it has been observed for water and proteins. We have found that benzene molecules confined in the metal organic framework MIL-47 move in a corkscrew fashion. This spectacular diffusion effect could be put into evidence by combining experimental and computation tools; the two experimental techniques, quasielastic neutron scattering and H-2 NMR, cover a wide range of time scales.
