Structural and morphological behaviours of l-Asparagine monohydrate at shocked conditions

Studies on the dynamic shock impact on solids also provide a magnificent scope of understating the stability of materials that are needed for high-pressure applications. Based on the impending investigations arising out of the observed experimental results of the shock-wave impact on solids, it is very much revealed that the impact of shock waves on molecular crystals is not yet well understood; especially amino acid crystals. Hence the present work deals with the assessment of crystallographic phase stability of l-Asparagine monohydrate (C4H8N2O3·H2O) amino acid powder samples against shocked-conditions and the results have been analyzed by X-ray powder diffractometry and scanning electron microscopy. The results of XRD and SEM reveal that the mother crystallographic phase of the title sample has significantly changed without inducing any crystallographic phase-transition and the observed structural modifications are discussed on the basis of previous publications reported on the static high-pressure study on the title sample.
