The melting and freezing of KI nanoparticles confined within zigzag single-walled carbon nanotubes based on molecular dynamics simulations

► The structures and properties confined KI nanoparticles are studied. ► The confined KI nanoparticles may have FCC or multishelled structure. ► The outermost layer of the confined (KI)N exhibits more order than the core. ► Some important thermodynamic and dynamic parameters are estimated.
