T. Yamaguchi et al., Preparation of anisotropic mesoporous glass and measurement of anisotropy in diffusion by traveling chemical waves, MACRO SYMP, 160, 2000, pp. 131-136
Anisotropic mesoporous glass of 30 nm pore diameter was prepared by stretch
ing the softened borosilicate glass along the z-axis before phase separatio
n (spinodal decomposition) took place. The anisotropy in diffusion was meas
ured from the velocity of the traveling chemical waves of the Belousov-Zhab
otinksy reaction that proceeded in the mesoporous glass.
