Investigation of anisotropic water mobility in oriented sub-nanometer hydrophobic pores

DOI

Diffusion or transport of water under complex geometries or in low dimensions is essential for the immense number of applications. The goal of our study is detailed characterization of the water diffusion in one dimensional oriented hydrophobic channels. For our study we use zeolite AlPO4-5 with oriented pore structure, which form one-dimensional channels with diameter of about 8 Å. In the feasibility study we have conducted on LET in September 2013 we observed a remarkable difference between the signal with the momentum transfer Q across and along the pore (fig.1). In the proposed study we plan to investigate the detailed Q and temperature dependences of the quasielastic scattering to establish diffusion constants and activation energies for the motions across and along the channels. The results can have far-reaching implications for our general understanding of the dynamics of fluids.
