“…Here, the TGA thermograms of the control and Biofield Energy Treated samples (Figure 3) exhibited four steps of thermal degradation, which was matched with the literature [47,48]. The % weight loss in the Biofield Energy Treated ferrous sulphate was significantly increased by 15.67% and 7.01% in the 1 st and 3 rd steps of degradation, respectively compared with the control sample.…”

Abstract:Ferrous sulphate is an inorganic salt of iron used to treat iron deficiency anaemia and maintain the overall health in our body. The current study was designed to evaluate the impact of The Trivedi Effect ® -Energy of Consciousness Healing Treatment on the physicochemical and thermal properties of ferrous sulphate using PXRD, PSA, DSC, and TGA/DTG analysis. Ferrous sulphate test item was divided into two parts, one part was considered as control (without Biofield Energy Treatment), whereas the second part received The Trivedi Effect ® -Biofield Energy Treatment remotely by the renowned Biofield Energy Healer, Alice Branton. The PXRD data revealed that the relative intensities and crystallite size of the characteristic diffraction peaks in the treated sample were significantly altered from -26.74% to 421.23% and from -24.93% to 42.91%, respectively compared with the control sample. The average crystallite size of the treated sample was significantly increased by 6.39% compared to the control sample. The particle size values at d 10 , d 50 , d 90 and D(4, 3) values were significantly increased by 30.43%, 35.94%, 19.49%, and 26.26%, respectively and the surface area was significantly decreased by 53.26% compared with the control sample. The melting temperature of the treated sample in the 1 st and 3 rd peaks was increased by 1.61% and 1.04% respectively, whereas decreased by 5.71% and 1.04% in the 2 nd and 4 th peaks, respectively compared with the control sample. Consequently, the total latent heat of fusion to transition from FeSO 4 •7H 2 O to FeSO 4 was decreased by 0.44% in the treated sample compared with the control sample. The TGA thermograms of both the samples exhibited four steps of thermal degradation. The total weight loss in the treated sample was increased by 0.62% compared with the control sample. The maximum thermal decomposition temperature (T max ) of treated sample was increased by 5.81% and 0.26% in the 1 st and 4 th peak respectively, but the T max of 2 nd and 3 rd peaks were decreased by 2.58% and 2.38%, respectively compared to the control sample. Overall, DSC and TGA/DTG of the treated sample showed that the thermal stability was changed compared with the control sample. The Trivedi Effect ® -Consciousness Energy Healing Treatment might lead to the production of a polymorphic form of ferrous sulphate, which would have better powder flowability and appearance with altered thermal stability compared to the control sample. Alice's Biofield Energy Treated ferrous sulphate would be useful to design better nutraceutical/pharmaceutical formulations, which could provide better therapeutic response against iron deficiency anaemia.

Summary Thermochemical heat storage materials offer high‐energy storage densities and clean means of long‐term solar energy storage. The aim of the study is to assess the potential heat storage efficiency of salt hydrates, based on sufficient hydration/dehydration performance, water sorption and cyclicability. MgSO4 7H2O, ZnSO4 7H2O and FeSO4 7H2O were evaluated based on preselected criteria. The main highlights of the dehydration result show that higher enthalpy was obtained for MgSO4 and ZnSO4, shows 2256 and 1731 J g−1 enthalpy, respectively. During hydration process, six water molecules were absorb by MgSO4 and ZnSO4 after pre‐dehydrated temperature 150°C and 120°C, respectively. The cycle stability of MgSO4 and ZnSO4 showed better performance which give rise 1210 g−1 and 1155 J g−1 enthalpy, respectively. It was expected that FeSO4 would show higher cyclicability due to their higher enthalpy (1400 J g−1) in the first round; however, overhydration does not permit it to released larger energy. The impact of relative humidity on water sorption performance and rate of hydration were reported which showed that MgSO4 and ZnSO4 can uptake maximum water under 85% and 75% relative humidity. Ongoing studies and the booming progress of ZnSO4 7H2O illustrate that likewise MgSO4 7H2O, it is also the potential candidate and can be use in thermochemical heat storage devices. To bring zinc sulfate heptahydrate into market, more detail studies in fields of evaluation of advanced materials and development of efficient and compact prototypes are still required.
