Specific heat and melting entropy of nanomaterials: Investigating the influence of shape via differential scanning calorimetry (DSC) Available to Purchase

This research activity proposes to assess the influence of nanoparticle morphology on the specific heat capacity and melting entropies of nanomaterials using Differential Scanning Calorimetry (DSC). Several varieties of nanoparticles, including spherical, rod-shaped, and cuboidal particles, were created and examined, exhibiting their diverse thermal properties. In particular, rod-shaped nanoparticles had a somewhat lower specific heat capacity of 0.31 J/g°C, while spherical nanoparticles had an average specific heat capacity of 0.38 J/g°C. Cuboidal nanoparticles, on the other hand, had a substantially higher specific heat capacity, with an average of 0.45 J/g°C. Furthermore, the analysis of melting entropy data indicated significant discrepancies across types. Spherical nanoparticles, for example, had an entropy of 17.9 J/g°C on average, rod-shaped nanoparticles had an entropy of 17.2 J/g°C, and cuboidal nanoparticles had a substantially higher entropy of 23.6 J/g°C. The findings show that shape has a considerable effect on thermal features, in addition to the link between nanoparticle form, surface area-to-volume ratios, and distinct thermal behaviors. Understanding these interactions allows for the tweaking of designs in nanomaterial engineering for applications requiring precise thermal characteristics.
