In the present article, we disclose shock wave induced crystallographic switchable phase transition of calcium carbonate nano particles (CaCO3 NPs). The observed profiles powder X-ray diffraction reveal that CaCO3 NPs undergoes transitions in sequential order from Calcite-I to Calcite-II and Calcite-III at 50 100 shocks, respectively. Interestingly, reversible have been 150 200 shocked conditio...

Liquid-liquid equilibrium (LLE) problems such as phase stability analysis, phase equilibrium calculations, chemical equilibrium calculations, binary interaction parameter identification of thermodynamic models and other problems of fluid characterization have been the core subject of many recent studies. This study introduces Cuckoo Search (CS), Firefly Algorithms (FA) and its variants as p...
