“…O-nitrophenol (ONP) and m-nitrophenol are important compounds which have been used as a reagent for synthesis of organic compounds [2]. Moreover, few nitrophenols are used as promising material for nonlinear optical and optoelectronic applications [3,4]. In order to attain this goal, these compounds not only have the presence of their electron donor "-OH" and electron acceptor "-NO 2 " substituents but also they can form strong hydrogen bonds with other compounds [5].…”

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 (T max ) as compared to control. However, the treated MNP showed slight decrease in T max 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.

“…Therefore, we need to consider that the average transmittance average T and the average value of the transmittance at these three positions is 30.1% ((27.0% + 41.5% + 21.8%)/3 = 30.1%). We estimate that the amplitude of the electric field, [13]. This indicates that the amplitude of an electric field twice as large as that from ZnTe could be obtained from a high quality DAP + NP -NP crystal.…”

“…This indicates that the amplitude of an electric field twice as large as that from ZnTe could be obtained from a high quality DAP + NP -NP crystal. Furthermore, the linear spectrum of DAP + NP -NP shows higher transmittance around 1000 nm in the NIR range [13]. Compared with the case using 800-nm optical pulses as the pump, we propose that it is possible to use the optical pumping pulse output from a Yb-doped fiber laser to obtain THz radiation with a high electric field.…”

We report few-cycle THz pulses emission from a novel organic crystal 2,6-diaminopyridinium-4-nitrophenolate-4-nitrophenol (DAPNPNP). The observed amplitude of the THz electric field from a DAPNPNP crystal is comparable with that from a ZnTe single crystal under the same optical pumping conditions. Both the waveform and spectra of the THz radiation from DAPNPNP are similar to those from ZnTe. We conclude that a high quality DAPNPNP crystal would be a high potential candidate in THz generation and applications.

“…It was found by Vijayan et al, [21] that, the 8-hydroxyquinoline crystal is stable up to a temperature of 113 °C. Chen et al, [24] have reported that another NLO crystal, 2,6-diaminopyridinium 4-nitrophenolate 4-nitrophenol starts decomposition at a temperature of 155°C. Thus, 4-Nitrophenol urea crystal has sufficient thermal stability required for a NLO crystal.…”
