Implication

Investigates enantiomer separation in alanine solutions under high pressure, suggesting implications for chiral purity in extraterrestrial environments.

Key Points

The aim is to explore a mechanism for amplifying l-enantiomeric excesses in alanine under high pressure.
Examined solubilities of l-alanine and dl-alanine using a diamond anvil cell under high pressure.
Compressed alanine crystals in saturated aqueous solutions up to 2 GPa.
Measured crystal volumes and solubility differences at varied l:d ratios.
l-alanine's solubility increased by 24% with pressure; dl-alanine's increased by only 2%.
Crystallization of high-pressure ice phases occurred alongside alanine crystallization.
In l:d = 7:3 systems, dl-alanine preferentially precipitated, while excess l-alanine remained in solution.
