Nanomaterial size and shape on melting entropy and enthalpy: A combined analysis through differential scanning calorimetry (DSC) Available to Purchase

This study used the Differential Scanning Calorimetry (DSC) method to examine the effect of nanoparticle size and shape on the fundamental thermal parameters, melting entropy and enthalpy. Nanoparticles with a wide variety of shapes and sizes (from spherical to rod-shaped to cuboidal) were synthesized and studied using differential scanning calorimetry (DSC). Melting entropy studies showed size-dependent patterns, with larger nanoparticles showing higher entropy. When it came to big nanoparticles, Sample A showed 16.9 J/g, medium nanoparticles 14.2 J/g, and small nanoparticles 12.5 J/g. Also, the melting enthalpy followed typical patterns that varied with nanoparticle size: 52.3 J/g for large nanoparticles, 48.9 J/g for medium nanoparticles, and 45.6 J/g for small nanoparticles were seen in Sample A. Results from Sample X demonstrated that different nanoparticle forms resulted in different enthalpy and entropy values. The values for the cuboidal, spherical, and rod-shaped nanoparticles were 16.5 J/g, 14.6 J/g, and 13.2 J/g, respectively. Likewise, there was a consistent pattern to the enthalpy values across all the types. These findings demonstrate how the thermal characteristics of nanoparticles are greatly affected by their size and shape. Insights into the creation of nanomaterials for specific applications reliant on precise thermal properties are also provided by these.
