Tuning of lower to higher crystalline nature of β-L-Glutamic acid by shock waves

Acoustic shock wave-induced dynamic recrystallization of amino acids: a case study on l-serine

“…Monohydrated l -asparagine undergoes significant lattice deformations, 27 whereas β- l -glutamic acid has a significantly higher degree of crystalline nature. 28 At the 50-shocked condition, l -leucine changes conformationally from phase-I (low-temperature P 2 1 ) to phase-II (high-temperature P 2 1 ), whereas phase-II remains unchanged up to 200 shocked conditions. 29 Similar shock wave recovery assessments have been carried out for non-polar acid materials such as glycine, 30 valine, 31 and isoleucine.…”

“…32 At this point in time, based on the current findings, the materials made of non-polar amino acids are more shock-resistant than those made of polar amino acids. 27–32 The literature indicates that, to date, there is no documentation of the shock wave recovery experiment conducted on l -serine. Furthermore, the title sample exhibits a high degree of potential scope to undergo polymorphic phase transitions under high pressure and temperature conditions without undergoing any chemical decomposition, as indicated by the static high-pressure results.…”

Experimental demonstration of acoustic shock-wave-induced solid-state morphological transformation from irregular to rod shape: a case study of l-tyrosine

“…14 Significant morphological changes have been observed following atomic structural transformations, particularly in materials containing amino acids. 15–18 In the case of β- l -glutamic acid, the degree of crystallinity has been found to increase with increasing number of shock pulses and with the original P 2 1 2 1 2 1 space group unaltered. 17 Conversely, a phase-I to phase-II transition has been observed for l -leucine subjected to 50 shock pulses.…”
