Direct evidence of rigidity loss and self-organisation in silicate glasses (2005)
Vaills, Y., Qu, T., Micoulaut, M., Chaimbault, F., Boolchand, P.
The Brillouin elastic free energy change $DF$ between thermally annealed and quenched $(Na_2O)_x(SiO_2)_{1-x}$ glasses is found to decrease linearly at $x > 0.23$ (floppy phase), and to nearly vanish...
Correlation between floppy to rigid transitions and non-Arrhenius conductivity in glasses (2005)
Malki, M., Micoulaut, M., Chaimbault, F., Vaills, Y.
Non-Arrhenius behaviour and fast increase of the ionic conductivity is observed for a number of potassium silicate glasses $(1-x)SiO_2-xK_2O$ with potassium oxide concentration larger than a certain...

Percolative conductivity in alkaline earth silicate melts and glasses (2003)
Malki, M., Micoulaut, M., Chaimbault, F., Vaills, Y., Simon, P.
Ion conducting $(CaO)_x(SiO_2)_{1-x}$ glasses and melts show a threshold behaviour in dc conductivity near $x=x_t=0.50$, with conductivities increasing linearly at $x>x_t$. We show that the behaviour...
