Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts

open access: yesAdvanced Science, EarlyView.
The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that
