|Characterization of Physical, Thermal and Spectral Properties of Biofield Treated Date Palm Callus Initiation Medium|
The date palm is mainly cultivated for the production of sweet fruit. Date palm callus initiation medium (DPCIM) is used for plant tissue culture applications. The present work is intended to evaluate the impact of Mr. Trivedi’s biofield energy treatment on physical, thermal and spectral properties of the DPCIM. The control and treated DPCIM were evaluated by various analytical techniques such as X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy, particle size analyzer (PSA), surface area analyzer and ultra violet-visible spectroscopy (UV-vis) analysis. The XRD analysis revealed a decrease in intensity of XRD peaks of the treated sample as compared to the control. The crystallite size of the treated DPCIM (81.02 nm) was decreased with respect to the control sample (84.99 nm). The DSC analysis showed a slight decrease in melting temperature of the treated sample. Additionally, the latent heat of fusion of treated sample was changed by 45.66% as compared to the control sample. The TGA analysis showed an increase in onset degradation temperature of the treated sample (182ºC) as compared to the control sample (142ºC). This indicated the increase in thermal stability of the treated DPCIM. PSA results demonstrated an increase in average particle size (d50) and size showed by 99% of particles (d99) by 19.2 and 40.4%, respectively as compared to the control sample. The surface area analyzer showed a decrease in surface area of treated DPCIM by 13.4%, which was well supported by the particle size results. UV spectra of the treated sample showed the disappearance of absorption peak 261 nm in treated sample as compared to the control. Overall, the result showed that biofield energy treatment has a paramount influence on physical, thermal and spectral properties of DPCIM. Therefore, it is assumed that biofield treated DPCIM could be used as a better medium for plant tissue culture applications.

Date palm or Phoenix dactylifera is a flowering plant belongs to the family Arecaceae, cultivated for its sweet fruits . The species is widely cultivated and naturalized in many tropical and subtropical regions worldwide. Dates have been used as staple food in the Middle East and Indus valley [2, 3]. Date palms have numerous health benefits as they produce antioxidant flavonoids such as β-carotene, lutein, and zeta xanthin, which have the ability to protect the cells and structures in the body from harmful effects of oxygen free radicals. Additionally, it has anticancer, anti-inflammatory and anti-hyperlipidemic activities . Date palm callus initiation medium (DPCIM) is used as tissue culture medium for microbiology applications. The ingredients of this medium are presented in Table 1 . Micropropagation is a true to type propagation of a selected genotype using in vitro culture techniques . Plant tissue culture technology provides a mean for a rapid, large-scale multiplication of plants and has been used for the propagation of crop and ornamental plants . Additionally, DPCIM can also be used for agriculture applications for improving crop production and pathogen elimination .
Sterilization is a process that removes all form of living organisms such as prions, viruses, fungi, bacteria, etc. from the tissue culture medium. In general autoclaving is used for sterilizing the media . It was reported previously that heat treatment of complex culture medium may result in nutrient destruction either by direct thermal degradation or by reaction between the components . Hence, an alternative strategies should be designed which can avoid these shortcomings and maintain the nutrient value of the culture medium. Recently, biofield treatment a plausible approach was considered as an alternative method for physicochemical modification of organic compounds , pharmaceutical drugs , and polymers .
The prestigious National Institute of Health (NIH)/The National Centre for Complementary and Alternative Medicine (NCCAM), permits the use of Complementary and Alternative Medicine (CAM) therapies as an alternative in the healthcare field. It was also reported that majority of patients use alternative therapies in combination with conventional medicine . Recently, an area of alternative medicine that is particularly amenable to use in a complementary way is called biofield energy therapy . Therefore, it is suggested that human beings have the ability to harness the energy from the surrounding environment/Universe and can transmit into any object (living or non-living) around the Globe. The object(s) always receive the energy and responding in a useful manner that is called biofield energy.
Mr. Mahendra Kumar Trivedi is a well-known healer of biofield energy therapy who can alter the characteristics in various research fields such as biotechnology  and microbiology . This unique biofield energy treatment is also known as The Trivedi Effect®. Hence, by capitalizing on the unique biofield energy treatment and properties of DPCIM as plant tissue culture medium, this research work was pursued to investigate the impact of biofield energy treatment on the physical, thermal and spectral properties of this compound. The control and treated samples were analyzed for their physicochemical properties using various analytical techniques such as X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, Fourier transform infrared spectroscopy, particle size analysis, surface area analysis and ultra violet-visible spectroscopy analysis.

2. Materials and Methods
Date Palm Callus Initiation Medium (DPCIM) was procured from HiMedia Laboratories, India. The sample was divided into two parts; one was kept as the control sample while the other was subjected to Mr. Trivedi’s unique biofield energy treatment and coded as treated sample. The treated sample was in sealed pack and handed over to Mr. Trivedi for biofield energy treatment under laboratory condition. Mr. Trivedi gave the energy treatment through his unique energy transmission process to the treated samples without touching it.
2.1. X-ray Diffraction (XRD)
XRD analysis of control and treated DPCIM was evaluated using X-ray diffractometer system, Phillips, Holland PW 1710 which consist of a copper anode with nickel filter. XRD system had a radiation of wavelength 1.54056 Å. The average crystallite size (G) was computed using formula:
G = kλ/(bCosθ)
Here, λ is the wavelength of radiation used, b is full-width half-maximum (FWHM) of peaks and k is the equipment constant (=0.94). Percentage change in average crystallite size was calculated using following formula:
Percentage change in crystallite size = [(Gt-Gc)/Gc] ×100
Where, Gc and Gt are denoted as crystallite size of control and treated powder samples respectively.
2.2. Differential Scanning Calorimetry (DSC)
The control and treated DPCIM samples were analyzed using Pyris-6 Perkin Elmer DSC at a heating rate of 10ºC/min, and the air was purged at a flow rate of 5 mL/min. The predetermined amount of sample was kept in an aluminum pan and closed with a lid. A reference sample was prepared using a blank aluminum pan. The percentage change in latent heat of fusion was calculated using following equations:
Where, ΔH Control and ΔH Treated are the latent heat of fusion of control and treated samples, respectively.
2.3. Thermogravimetric Analysis-Differential Thermal Analysis (TGA-DTA)
A Mettler Toledo simultaneous TGA and differential thermal analyzer (DTA) was used to investigate the thermal stability of control and treated DPCIM samples. The rate of heating was 5ºC/min, and samples were heated in the range of room temperature to 400ºC under air atmosphere.
2.4. FT-IR Spectroscopy
The FT-IR spectra were recorded on Shimadzu’s Fourier transform infrared spectrometer (Japan) with the frequency range of 4000-500 cm-1.
2.5. Particle Size Analysis
The average particle size and particle size distribution were analyzed by using Sympetac Helos-BF Laser Particle Size Analyzer with a detection range of 0.1 micrometer to 875 micrometer. Average particle size d50 and d99 size exhibited by 99% of powder particles were computed from laser diffraction data table. The d50 and d99 values were calculated by the following formula:
Percentage change in d50 size = 100 × (d50 treated- d50 control)/d50 control
Percentage Change in d99 size = 100× (d99 treated- d99 control)/d99 control
2.6. Surface Area Analysis
The surface area of DPCIM was characterized using surface area analyzer, Smart SORB 90 BET, which had a detection range of 0.1-100m2/g.
2.7. UV-Vis Spectroscopic Analysis
A Shimadzu UV-2400 PC series spectrophotometer with 1 cm quartz cell and a slit width of 2.0 nm was used to obtain the UV spectra of the control and treated DPCIM samples. The spectroscopic analysis was carried out using the wavelength in the range of 200-400 nm and methanol was used as a solvent.
3. Results and Discussions
3.1. XRD Study
XRD is a non-destructive analysis technique that is used to evaluate the crystalline nature of the materials. The XRD diffractogram of control and treated DPCIM are presented in Figure 1. The XRD diffractogram of control and treated samples showed intense peaks that were due to their crystalline nature. XRD diffractogram of control sample showed peaks at 2θ equal to 11.66º, 12.73º, 13.14º, 15.52º, 16.72º, 18.84º, 19.57º, 20.37º, 20.82º, 22.03º, 23.51º, 24.74º, 25.21º, 29.38º and 30.99º. Additionally, the treated sample showed the presence of XRD peaks at 2θ equal to 11.67º, 12.68º, 13.14º, 15.46º, 16.71º, 18.80º, 19.56º, 20.35º, 20.81º, 22.00º, 23.50º, 24.72º, 25.18º, 29.35º and 30.97º. It was observed that 2θ angle (Braggs angle) of XRD peaks of treated sample were decreased at 2θ equals to 12.73º→12.68º, 15.52º→15.46º as compared to the control sample. Additionally, the result suggested the decrease in intensity of XRD peaks of treated sample as compared to the control. It was reported that atoms undergo thermal vibrations about their means positions even at the absolute zero temperature and amplitude of this vibration increase with elevation in temperature. The increase in temperature causes thermal vibration of atoms as a result unit cell may expand, causing changes in plane spacing d and thus, in the 2θ positions of XRD peaks . Additionally, this might cause a decrease in intensity of diffraction peaks. Thus, it is assumed here that biofield treatment may provide the thermal energy that led to increase in the unit cell, changes in plane spacing, and this ultimately decreases the intensity of the XRD peaks of the treated sample. The crystallite size was computed using the well-known Scherrer’s formula and data are presented in Figure 2. The crystallite size of the control sample was 84.99 nm, and it decreased up to 81.02 nm in the treated sample. The results suggested 4.67% decrease in crystallite size of the treated DPCIM as compared to the control sample. Additionally, researchers have also shown that occurrence of micro strain causes a decrease in crystallite size of the materials. Zhang et al. showed that presence of strain and increase atomic displacement from their ideal lattice positions causes a reduction in crystallite size . Moreover, Pavia-santos et al. also reported a uniform decrease in crystallite size with the increase in micro-strain . Thus, it is assumed that biofield energy treatment may cause micro strain in treated DPCIM molecules that led to the rapid displacement of an atom from their original lattice positions and ultimately decreases the crystallite size.
3.2. DSC Study
DSC studies were conducted to get the insights about the thermal nature, i.e. melting temperature and latent heat of fusion of the samples. The DSC thermogram of the control sample showed (Figure 3) an endothermic peak at 156.93ºC, which was due to melting temperature of the control sample. This peak was perhaps due to the melting of the sucrose content in the sample . The DSC thermogram of control sample showed another endothermic peak at around 172ºC that may be associated with thermal decomposition of the sample. However, the treated sample also showed two endothermic transitions in the DSC thermogram. The first endothermic peak was due to melting temperature (155.89ºC) and the second peak was due to thermal decomposition (166.66ºC) of the treated sample. Hence, the results suggested no significant change in melting temperature of the treated sample as compared to the control.
The latent heat of fusion was obtained from the DSC thermogram of control and treated samples. It was reported that energy required to overcome the intermolecular interaction between molecules is known as potential energy. This potential energy is stored in the material during its phase change from solid to liquid form. The control sample showed a latent heat of fusion of 129.75 J/g and it was decreased to 70.50 J/g in the treated sample. The result suggested that latent heat of fusion was decreased by 45.66% as compared to the control. It is presumed that the treated sample may present in the high-energy state that led to an alteration in latent heat of fusion of the treated sample. Recently, it was reported that biofield treatment has caused an alteration in latent heat of fusion of indole .
3.3. TGA Analysis
TGA is mainly used to investigate the thermal properties such as a change in weight loss, oxidation, and thermal decomposition pattern of the materials. TGA thermogram of control and treated samples are presented in Figure 4. The TGA thermogram of control DPCIM showed three steps thermal degradation pattern. The first thermal degradation commenced at around 153ºC, and it was terminated at around 183ºC. The second thermal degradation was started at around 225ºC and stopped at around 245ºC. Whereas, the third thermal degradation event was commenced at 285ºC and terminated at 315ºC. The sample lost 15.17, 7.63 and 15.14% weight during the first, second and third thermal degradation event, respectively. Contrarily, the treated DPCIM sample showed two-step thermal decomposition. The first step was started at around 154ºC and stopped at around 200ºC. However, the second thermal decomposition was started at 250ºC and terminated at 380ºC. The treated sample lost around 11.19 and 32.12% weight during these two decomposition steps.
DTG thermogram of control and treated samples are shown in Figure 4. The DTG thermogram of control sample showed maximum weight loss occurred at 142, 196, 298 and 355ºC. The weight loss from 196ºC was mainly due to the release of volatile matter and decomposition of the sample . Whereas, the treated sample showed maximum weight loss at 182 and 299ºC. Thus, based on DTG curve the control sample showed the onset of thermal degradation at 142ºC, and it was increased to 182ºC in the treated sample. This might be due to increase in thermal stability of the biofield treated sample as compared to control. Szabo et al. reported that thermal stability of doped poly (hexadecylthiophene) polymer was increased after γ-radiation treatment . They proposed that γ-radiation treatment causes conformational changes and crosslinking in side alkyl groups that led to increase in the thermal stability of the polymer. Therefore, it is hypothesized that biofield energy treatment perhaps caused crosslinking and conformational changes in treated DPCIM molecules that led to increase in thermal stability. Moreover, the high thermal stability of the treated DPCIM might improve the stability of nutrients during sterilization as compared to the control.
3.4. FT-IR Spectroscopy
FT-IR spectrum of control and treated DPCIM are shown in Figure 5. The sample contains various ingredients such as sucrose, activated charcoal, EDTA, and agar. The FT-IR spectrum of the control DPCIM showed O-H stretching vibration peaks at 3384, and 3332 cm-1. However, the treated sample showed O-H stretching vibration peak at 3384 and 3336 cm-1. These broad hydroxyl peaks were mainly due to the presence of sucrose and agar in the control and treated samples. The vibration bands for C-H stretching was observed at 2985 and 2941 cm-1 in the control and treated samples, respectively. The peak at 1768 cm-1 in control and treated samples were mainly due to lactone ring of the sucrose molecule. The IR peak observed at 1635, and 1672 cm-1 were attributed to the C=O group of the EDTA or sucrose present in the control and treated samples. The vibration peaks at 1417 and 1419 cm-1 were due to –CH bending peaks in the control and treated samples, respectively. The IR peak observed at 1380 cm-1 in the control sample, and 1379 cm-1 in treated DPCIM sample were attributed to N=O group from the ammonium nitrate or potassium nitrate in the sample . Similarly, the vibration peaks at 1344 cm-1 in control and 1348 cm-1 in treated sample were due to the sulfate (S=O) ions present in the samples . Moreover, the peak at 1236 cm-1 in control and treated samples were due to C-C stretching. The vibrational bands at 1060 and 1066 cm-1 were observed due to C-O stretching in the control and treated sample, respectively. Additionally, the vibration peaks for metal halide and aromatic stretching were observed at 682 cm-1, and 860 cm-1 in the control sample. However, these peaks were observed at 686 cm-1 and 860 cm-1 in the treated sample. Overall, the result showed no significant change in IR peaks of the treated sample as compared to the control sample. It is assumed that biofield treatment had not influenced the dipole moment, and force constant of the treated DPCIM.
3.5. Particle Size and Surface Area Analysis
PSA was accomplished using a laser particle analyzer and data are reported in Figure 6. The average particle size (d50) of the control sample was 18.38 μm, and it was increased upto 21.9 μm in the treated sample. However, the size exhibited by 99% of particles (d99) of the control sample was 263.44 μm, and it was increased substantially to 369.78 μm in the treated sample. The result suggested that d50 and d99 were increased by 19.2 and 40.4% respectively as compared to the control sample. It was reported that increase in annealing temperature increases the particle size of materials. For instance, Iqbal et al. reported that elevation in annealing temperature cause the particles to collide and coalesce to form bigger microparticles . Zhang et al. also suggested that higher annealing temperature resulted in increased particle size of cerium-zirconium binary oxide nanoparticles . Thus, we assume here that biofield energy treatment perhaps provided the thermal energy that causes collision and increase in particle size of treated DPCIM. Many reports suggested that higher water uptake of an organic product such as rice bran, mainly depends on its particle size [27-29]. It was envisaged that larger sized particles take up more water as compared to smaller particles . Albers et al., in a research study showed that Farinograph water absorption also decreased with decreasing particle size . Hence, bigger macroparticles are likely to show more water uptake and this property could improve its gelling properties. Thus, the treated sample might confer better properties as tissue culture medium.
The surface area of the control and treated sample was evaluated using BET analyzer. The surface area of the control sample was 28.49 m2/g, and it was decreased to 24.68 m2/g in the treated sample. The result demonstrated 13.4% decrease in surface area of the treated sample as compared to the control. Researchers have shown that particle size is inversely proportional to surface area . Hence, increase in particle size may cause a decrease in surface area and vice versa. Therefore, an increase in particle size of treated DPCIM sample caused a decrease in surface area as compared to the control.
3.6. UV Visible Spectroscopy
UV spectra of control and treated DPCIM samples are presented in Figure 7. The UV spectrum of control DPCIM showed absorption peaks at 210 and 261 nm. However, the treated sample showed similar absorption peak at 210 nm as showed by the control sample. Nevertheless, the second absorption peak originally present at 261nm in control was completely disappeared in the treated sample. According to Cinarli et al. the absorption peak appears in the region of 210-290 nm are mainly due to n→ π* and π – π* transition of the aromatic rings . Hence, it is assumed here that due to biofield treatment alterations occurred in electron i.e. bonding (n→ π* and π→π* transition) from the ground state to excited state that led to a disappearance of the absorption peak in the treated sample.
In summary, the XRD analysis showed a decrease in crystallite size of treated DPCIM as compared to the control sample. Moreover, the intensity of the XRD peaks of treated sample was decreased with respect to the control. It is assumed that presence of micro strain causes a decrease in crystallite size of the treated sample. The DSC analysis showed a decrease in latent heat of fusion of treated sample by 45.66% with respect to the control sample. It is assumed that treated sample might be present in the high-energy state that led to an alteration in latent heat of fusion of the sample. The TGA evaluation showed a substantial increase in onset temperature of treated sample (182ºC) as compared to the control sample (142ºC). The PSA analysis results showed a substantial increase in d50 and d99 by 19.2 and 40.4% respectively with respect to control. This was well supported by surface area result that was decreased by 13.4% in the treated sample. It is presumed that the high thermal stability and bigger particle size might improve DPCIM uses as tissue culture medium. Hence, it is presumed that biofield treated DPCIM could be used as a medium for plant tissue culture applications.
