摘要: Fluorescence recovery after pattern photobleaching is used to measure the self-diffusion of surfactant molecules, along cylinders and perpendicular their main axis in an oriented hexagonal lyotropic phase. Unexpectedly, while motion diffusive, a superdiffusive behavior observed direction cylinder axis. Moreover, varying lattice parameter, we found that diffusion time governed only by number cross, providing experimental evidence for superdiffusion with bounded step length.
