Lattice-dynamical study of the structure and elasticity of dodecasil-3Cat elevated temperatures

Do Zeolites Have Negative Poisson’s Ratios?

“…[35] Comparison of these predicted values with experimental data for dodecasil-3C with guest molecules N 2 , Ar, and N(CH 3 ) 3 in the framework cages imply that only a small effect on the elastic constants is expected due to the presence of guest molecules. The all-silica analogues have the advantage that, due to possessing a neutral charge, no cations would be expected within the framework cavities.…”
