Unified model for the prediction of thermophysical properties of nanometals
2023, Solid State CommunicationsResearch on size dependent integral melting thermodynamic properties of Cu nanoparticles
2020, Journal of Chemical ThermodynamicsCitation Excerpt :However, the relation between the melting thermodynamic properties and the size of copper nanoparticles has not been reported. In the present size-dependent melting enthalpy and entropy relations [14–22], the melting enthalpy and entropy belong to the differential quantities at the initial melting temperature. When merely a few nanoparticles melt, the change in thermodynamic properties translates into a mole change.
A theoretical study on the size and morphology dependency of integral melting enthalpy and entropy of nanomaterials
2020, Journal of Physics and Chemistry of SolidsCitation Excerpt :To explore the melting thermodynamics of nanomaterials, various approaches, including theoretical models [7–9], molecular dynamics simulations [10,11] and experiments [12,13] have been utilized and the results have demonstrated melting temperature reduction for nanomaterials. To better understand the thermodynamic behaviors of nanomaterials during the melting process, plenty of theoretical models have been proposed to study the size dependent melting enthalpy and entropy of nanomaterials, including vibrational entropy model [14], bond energy model [15–17], lattice type sensitive model [18,19], Gibbs energy difference model [20]. Most of the previous researches focus on the size dependent melting enthalpy and entropy which are able to describe the melting behavior of nanomaterials at the initial melting stage but fail to the whole melting process.
