It is generally well known that not only the sodium itself, but also the non‐bridging oxygen
(NBO) sites associated with sodium ions are largely responsible for the surface reactivity of …

Thermal poling of glasses induces structural and compositional modification and breaks
central symmetry of these initially isotropic media. In spite of numerous experimental data …

Motivated by the advantages of two-electrode flash sintering over normal sintering, we have
investigated the effect of an external electric field on the viscosity of glass. The results show …

The mechanical and mechanochemical properties of soda lime silica (SLS) glass surfaces
