As a complement to real-time study of dynamic compression by in situ experiments and simulations, we will carry out recovery of shocked material and detailed characterization of the recovered products, in order to assess the possible formation of dense crystalline phases and recoverable changes upon impact in the structure of amorphous silicates, especially soda-lime glass. We will carry out new recovery experiments on isotopically-enriched starting glass, suitable for nuclear magnetic resonance characterization We will analyze recovered powders supplied by ONR from experiments conducted elsewhere alongside our starting materials and new recovery samples Both the existing and new samples will be studied by optical and electron microscopy, optical and X-ray Raman spectroscopy, X-ray diffraction, and NMR spectroscopy in order to characterize, at multiple scales from atomic-level upwards, the changes in structure and ordering after shock and recovery. The suite of analyses targets both bulk properties and element-selective properties and can be adapted to determine the local environment around O, Na, Al, Si, and Ca atoms.
