Neopentyl glycol (NPG) has been extensively used as solid-solid phase change materials (PCMs) for thermal energy storage applications. The objective of the present study was to evaluate the impact of biofield treatment on physical, spectral and thermal properties of NPG. The study was performed in two groups (control and treated). The control group remained as untreated, and treatment group was subjected to Mr. Trivedis biofield treatment. The control and treated NPG were characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and Fourier transform infrared (FT-IR) spectroscopy. XRD study revealed the decrease in crystallite size of treated NPG by 21.97% as compared to control sample. DSC studies showed slight change in melting temperature of treated NPG as compared to control sample. TGA analysis showed 55.66% weight loss in control NPG however, the treated sample showed reduction in weight loss (44.81%). Additionally, the maximum thermal decomposition temperature (Tmax) of treated NPG (160.40°C) was minimally increased with respect to control sample (159.72°C). This can be inferred as good thermal stability of biofield treated NPG with respect to control. FT-IR spectroscopy showed no structural changes in treated NPG with respect to control sample. The overall results showed that biofield treatment has affected the physical and thermal properties of treated NPG. Moreover, good thermal stability of treated NPG showed that it could be used as phase change materials for thermal energy storage applications.
In the present work biofield treatment has significantly affected the physical and thermal properties of the NG. XRD study revealed the increase in intensity of XRD peaks with respect to control. However, significant decrease in crystallite size of treated NPG with respect to control was observed. DSC analysis showed minimal change in melting temperature of treated NPG with respect to control sample. Moreover, decrease in weight loss of treated NPG was noticed as compared to control. Additionally, the Tmax was minimally increased in treated NPG as compared to control that corroborated the thermal stability of the sample. FT-IR spectroscopic results of treated NPG showed no structural changes with respect to control. The stable melting temperature and appreciable thermal stability showed that the treated NPG could be a potential candidate for fabrication of PCMs for thermal energy storage applications.
