The structural. electronic. elastic and optic properties of NaYSi formed in the half-Heusler structure are studied by using ab-initio density-functional theory. The calculated equilibrium lattice constants are compaired with the available experimental and theoretical data. https://wfpwtch4aasx3.blog-kids.com/35128693/this-is-fine-the-impact-of-blowouts-on-subsequent-game-performance-in-the-national-hockey-league-nhl
