Description 1029-1039
To improve the use of nanoparticles, it is imperative to comprehend the patterns and mechanisms driving their melting.
The melting transformation thermodynamics has many formulas because of the phase equilibrium integrity and equilibrium
presupposition of the different models. The analysis of the melting temperature depression for the nanoparticles has been
done using a variety of melting models that have been published in the literature. These models include the following:
Pawlow theory; Homogenous growth model; Heterogeneous growth model; Liquid nucleation & growth model; Liquid shell
model; Homogenous melting and growth model; Bond order length strength model; Homogenous melting hypothesis;
Liquid skin melting model; Reiss melting model and Rie melting model; Liquid drop model; Gibbs Thomson equation;
Surface phonon instability model; and so on. In order to lower the melting point of the nanoparticles, this study reviews
several melting models. The melting models align with the observed value of minute particles. Furthermore, the relationship
between exact thermodynamic equations and their approximate counterparts is presented, as is the shift in melting
temperature that occurs when nanoparticles melt.
