Abstract
Tellurium has gained significant attention due to its photoconductivity, piezoelectricity, and thermo conductivity properties. The aim of this study was to evaluate the effect of biofield energy treatment on thermal, physical and atomic properties of tellurium powder. The tellurium powder was equally divided in two parts: control and treated (T). The treated part was subjected to Mr. Trivedi’s biofield energy treatment, whereas the control part was remained untreated. Subsequently, the control and treated samples were characterized using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Fourier transform infrared (FT-IR) spectroscopy. The DSC data showed that latent heat of fusion was decreased by 14.13, 21.90, and 5.55% in treated samples T1, T2, and T3, respectively as compared to the control. However, the melting temperature did not show any change in treated samples as compared to the control. The TGA data showed that the peak width (difference in onset and endset) was increased from 213.67°C (control) to 234.82°C in treated tellurium sample. Besides, XRD results exhibited an alteration in lattice parameter, unit cell volume, density, atomic weight and nuclear charge volume of the treated tellurium powder as compared to the control. In addition, the crystallite sizes were significantly changed on crystalline plane (102) and (110) as 146.05→48.67 nm and 63.01→88.21 nm, respectively in the treated tellurium. The FT-IR spectra did not show any significant change in absorption frequencies in treated sample as compared to the control. Therefore, DSC, TGA and XRD data suggested that Mr. Trivedi’s biofield energy treatment has significantly altered the thermal and physical properties of tellurium powder. Thus, biofield energy treatment could be applied to modulate the thermal and physical properties in semiconductor and chalcogenide glass industries.
