Experimental Findings

Raman scattering has been employed to study the temperature and polarization dependence of the vibrational modes for the glass-forming halide salt mixtures xZnCl2-(1-x)AlCl3, with x = 0.8 and 0.6. The analysis has shown that the vibrational modes of the mixtures arise from a contribution of the vibrational modes of the pure components salts. Emphasis has also been given to the low-frequency modes (3 - 80 cm-1), and particular points related to the glass transition phenomenology are discussed in view of the experimental findings.

We determine how low frequency vibrational modes control the elastic shear modulus of Mikado networks, a minimal mechanical model for semi-flexible fiber networks. From prior work it is known that...
