Specific heat and enthalpy of nanomaterials: Analyzing the influence of size and shape with differential scanning calorimetry (DSC) Available to Purchase

The purpose of this research is to evaluate the impact that the size and shape of nanoparticles have on specific heat and enthalpy, which are basic thermal parameters that are essential in other applications. Through the use of Differential Scanning Calorimetry (DSC), nanoparticles of varying sizes (small, medium, and large) and forms (spherical, rod-shaped, and cuboidal) were produced and then subjected to a comprehensive thermal characterization. A size-dependent behavior was discovered by the analysis of specific heat capacities, which demonstrated increases as the size of the nanoparticles rose. For instance, Sample A exhibited specific heat capacities of 0.38 J/g°C (small), 0.42 J/g°C (middle), and 0.49 J/g°C (big). These values vary depending on the temperature. In a similar manner, measurements of enthalpy demonstrated similar patterns, with increases being associated to differences in nanoparticle size. Additionally, differences in nanoparticle form were noticed, which shed light on the fact that various shapes had varied specific heat capacities and enthalpies. As an example, the specific heat capacities of Sample X were 0.41 J/g°C for spherical, 0.37 J/g°C for rod-shaped, and 0.45 J/g°C for cuboidal. These results illustrate the enormous influence that the size and shape of nanoparticles have on specific heat and enthalpy, underscoring the need of designing nanomaterials in a customized manner for applications that are dependent on precise thermal characteristics.
