Abstract
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. Trivedi’s 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 (159.72oC). 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.
Highlights
The global price rise of petroleum products and fossil fuel has led scientists to design new strategies for thermal energy regeneration and conservation
By considering the phase change property of neopentyl glycol (NPG), authors decided to investigate the influence of biofield treatment on its physical, spectral and thermal properties which could be further utilized for thermal storage applications
It is hypothesized that biofield treatment may induced long-range symmetrical pattern in the treated NPG as compared to control that led to increase in crystallinity
Summary
The global price rise of petroleum products and fossil fuel has led scientists to design new strategies for thermal energy regeneration and conservation. The latent heat storage devices (LTHS) prepared from phase change materials (PCMs) are interesting choice for thermal energy storage applications. The LTHS are widely used in several applications such as condensation heat recovery, building energy conservation, temperature regulating textiles and solar energy systems [1,2,3,4]. Many compounds have been used recently for fabricating the LTHS i.e., fatty acids, poly ethylene glycol (PEG), alcohols and mixture of them. Neopentyl glycol (NPG) was investigated as potential material for solid-solid PCMs [11]. By considering the phase change property of NPG, authors decided to investigate the influence of biofield treatment on its physical, spectral and thermal properties which could be further utilized for thermal storage applications
