Phenolic compounds are commonly used for diverse applications such as in pharmaceuticals, chemicals, rubber, dyes and pigments. The objective of present research was to study the impact of Mr. Trivedi’s biofield treatment on physical and thermal properties of phenol derivatives such as o-nitrophenol (ONP), m-nitrophenol (MNP) and p-tertiary butyl phenol (TBP). The study was performed in two groups (control and treated). The control and treated compounds were characterized using X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and surface area analysis. XRD analysis showed increase in crystallite size by 16.05% in treated ONP as compared to control. However, the treated MNP showed decrease in crystallite size by 16.17% as compared to control. The treated TBP showed increase in crystallite size by 5.20% as compared to control. DSC of treated MNP exhibited increase in melting temperature with respect to control, which may be correlated to higher thermal stability of treated sample. However, the treated TBP exhibited no significant change in melting temperature with respect to control. TGA analysis of treated ONP and TBP showed an increase in maximum thermal decomposition temperature (Tmax) as compared to control. However, the treated MNP showed slight decrease in Tmax in comparison with control sample. Surface area analysis of treated ONP showed decrease in surface area by 65.5%. However, surface area was increased by 40.7% in treated MNP as compared to control. These results suggest that biofield treatment has significant effect on physical and thermal properties of ONP, MNP and TBP.
