New IBI-4 article in J. Chem. Phys.: When bigger is faster 


Generally, it is assumed that big particles diffuse slower than small particles. In a recent feature article of JCP we show that this assumption does not always hold.
Our video microscopy experiments on rod-like viruses show that large rods can diffuse faster than small rods, when they are embedded in a smectic phase consisting of layers of short host rods.
The reason is that the long rods do not feel the ordering potential of the layers, as they create their own space in adjacent layers.
