Physicochemical, Thermal and Spectroscopic Characterization of Sodium Selenate Using XRD, PSD, DSC, TGA/DTG, UV-vis, and FT-IR
Mahendra Kumar Trivedi, Kalyan Kumar Sethi, Parthasarathi Panda, Snehasis Jana
Marmara Pharmaceutical Journal , 2017, DOI: 10.12991/marupj.300796
Abstract: Sodium selenate is an important inorganic compound but lacks reliable and accurate physico-chemical and spectral characterization information. The study was carried out for the in-depth physicochemical, thermal, and spectroscopic characterization of sodium selenate using various analytical techniques. The powder X-ray diffraction spectroscopy analysis showed well-defined and sharp peaks indicated sodium selenate is crystalline in nature. The crystallite size was found to be in the range of 28.75 to 49.97 nm. The average particle size was found to be of 3.93 (d10), 14.44 (d50), and 40.648 (d90) μm with an average surface area of 0.676 m2/g. The differential scanning calorimetry showed the endothermic inflation at 588.81 °C with the latent heat of fusion 103 J/g. The thermogravimetric analysis revealed two steps of the thermal degradation process. Similarly, the differential thermogravimetric analysis exhibited the major peaks in the thermogram and disclosed Tmax at 852.65 °C. The UV-visible spectrum showed maximum absorbance at 205.1 nm (λmax). The Fourier transform infrared spectrum showed a peak at 888 cm-1 due to the Se-O stretching. This information would be very much useful in the field of nutraceuticals/ pharmaceuticals and other industries using sodium selenate as an ingredient.

Abstract: Methyl-2-napthylether (nerolin) is an organic compound and has the applications in pharmaceutical, and perfume industry. The stable isotope ratio analysis is increasing importance in various field of scientific research. The objective of the current study was to evaluate the effect of the biofield energy treatment on the isotopic abundance ratios of PM 1/PM (2H/1/sup>H or 13C/12C or 17O/16O) and PM 2/PM (18O/16O) in nerolin using the gas chromatography-mass spectrometry (GC-MS). The compound nerolin was divided into two parts - one part was control sample (untreated), and another part was considered as biofield energy treated sample which was received the biofield energy treatment through the unique biofield energy transmission process by Mr. Mahendra Kumar Trivedi (also known as The Trivedi Effect ). The biofield energy treated nerolin was analyzed at different time intervals and were represented as T1, T2, T3, and T4 in order to understand the effect of the biofield energy treatment on isotopic abundance ratio with respect to the time. From the GC-MS spectral analysis, the presence of the molecular ion peak C11H10O (m/z 158) along with major fragmented peaks C10H7O- (m/z 143), C10H8 (m/z 128), C9H7 (m/z 115), C7H5 (m/z 89), C5H3 (m/z 63), C4H3 (m/z 51), and C3H3 (m/z 39) were observed in both control and biofield treated samples. Only, the relative peak intensities of the fragmented ions in the biofield treated nerolin was notably changed as compared to the control sample with respect to the time. The isotopic abundance ratio analysis of nerolin using GC-MS revealed that the isotopic abundance ratio of PM 1/PM in the biofield energy treated nerolin at T1, T2, T3, and T4 was increased by 2.38, 138.10, 13.10, and 32.14%, as compared to the control sample. Likewise, the isotopic abundance ratio of PM 2/PM at T1, T2, T3, and T4 was increased by 2.38, 138.10, 13.10, and 32.14%, respectively in the biofield treated nerolin as compared to the control sample. Overall, the isotopic abundance ratios of PM 1/PM (2H/1H or 13C/12C or 17O/16O) and PM 2/PM (18O/16O) were significantly increased in the biofield energy treated sample as compared to the control sample with respect to the time. It is concluded that Mr. Trivedi’s biofield energy treatment has the significant impact on alteration in isotopic abundance of nerolin as compared to the control sample. The biofield treated nerolin might display different altered physicochemical properties and rate of reaction and could be an important intermediate for the production of pharmaceuticals, chemicals, and perfumes in the industry.
Optimization of Electrical Parameters for Production of Carbon Nanotubes  [PDF]
Sayantan Chattopadhyay, Kalyan Kumar Singh
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2012, DOI: 10.4236/jmmce.2012.1110095
Abstract: For more than two decades, there had been extensive research on the production of carbon nanotubes (CNT) and opti- mization of its manufacture for the industrial applications. It is believed that they are the strong enough but most flexi- ble materials known to mankind. They have potential to take part in new nanofabricated materials. It is known that, carbon nanotubes could behave as the ultimate one-dimensional material with remarkable mechanical properties. More- over, carbon nanotubes exhibit strong electrical and thermal conducting properties. In the process of optimizing the production in line with the industrial application, the researchers have found a new material to act as an anode i.e. coal, which is inexpensive as compared to graphite. There are various methods such as arc discharge, laser ablation, chemical vapour deposition (CVD), template-directed synthesis and the use of the growth of CNTs in the presence of catalyst particles. The production of carbon nanotubes in large quantities is possible with inexpensive coal as the starting carbon source by the arc discharge technique. It is found that a large amount of carbon nanotubes of good quality can be ob- tained in the cathode deposits in which carbon nanotubes are present in nest-like bundles. This paper primarily concen- trates on the optimising such parameters related to the mass production of the product. It has been shown through Sim- plex process that based on the cost of the SWNT obtained by the arc discharge technique, the voltage and the current should lie in the range of 30 - 42 V and 49 - 66 A respectively. Any combination above the given values will lead to a power consumption cost beyond the final product cost, in turn leading to infeasibility of the process.

Abstract: The current research work was designed to explore the impact of The Trivedi Effect - Energy of Consciousness Healing Treatment (Biofield Energy Healing Treatment) on magnesium gluconate for the change in the structural properties and isotopic abundance ratio (PM+1/PM and PM+2/PM) by using LC-MS and NMR spectroscopy. Magnesium gluconate was divided into two parts – one part was control, and another part was treated with The Trivedi Effect- Biofield Energy Healing Treatment remotely by seven renowned Biofield Energy Healers and defined as The Trivedi Effect Treated sample. The LC-MS analysis of the both control and treated samples revealed the presence of the mass of the protonated magnesium gluconate at m/z 415 at the retention time of 1.53 min with similar fragmentation pattern. The relative peak intensities of the fragment ions of the treated sample were significantly changed compared with the control sample. The proton and carbon signals for CH, CH2 and CO groups in the proton and carbon NMR spectra were found almost similar for the control and the treated samples. The isotopic abundance ratio analysis revealed that the isotopic abundance ratio of PM+1/PM (2H/1H or 13C/12C or 17O/16O or 25Mg/24Mg) in the treated sample was significantly increased by 34.33% compared with the control sample. Subsequently, the percentage change of the isotopic abundance ratio of PM+2/PM (18O/16O or 26Mg/24Mg) was significantly decreased in the treated sample by 64.08% as compared to the control sample. Briefly, 13C, 2H, 17O, and 25Mg contributions from (C12H23MgO14)+ to m/z 416; 18O and 26Mg contributions from (C12H23MgO14)+ to m/z 417 in the treated sample were significantly changed compared with the control sample. Thus, the treated magnesium gluconate could be valuable for designing better pharmaceutical and/or nutraceutical formulations through its changed physicochemical and thermal properties, which might be providing better therapeutic response against various diseases such as diabetes mellitus, allergy, aging, inflammatory diseases, immunological disorders, and other chronic infections. The Biofield Energy Treated magnesium gluconate might be supportive to design the novel potent enzyme inhibitors by using its kinetic isotope effects.

Abstract: Magnesium gluconate is a classical organometallic salt used for the prevention and treatment of magnesium deficiency diseases. The objective of the current research was to explore the influence of The Trivedi Effect - Energy of Consciousness Healing Treatment (Biofield Energy Healing Treatment) on magnesium gluconate for the change in the physicochemical, structural, thermal and behavioral properties using PXRD, PSD, FT-IR, UV-vis spectroscopy, TGA, and DSC analysis. Magnesium gluconate was divided into two parts – one part was control, while another part was treated with The Trivedi Effect - Energy of Consciousness Healing Treatment remotely by seven renowned Biofield Energy Healers and defined as the Biofield Energy Treated sample. The PXRD analysis exhibited significant alteration of the crystal morphology of the treated sample compared with the control sample. The crystallite size of the treated sample was remarkably changed from range -69.99% to 71.40% compared with the control sample. The average crystallite size was significantly decreased in the treated sample by 13.61% compared with the control sample. Particle size analysis revealed that the particle size in the treated sample at d10, d50, and d90 value was significantly decreased by 5.19%, 26.77%, and 18.22%, respectively compared with the control sample. The treated sample’s surface area was significantly enhanced (12.82%) compared with the control sample. The FT-IR and UV-vis analysis showed that the structure of the magnesium gluconate remained the same in both the treated and control samples. The TGA analysis revealed the four steps thermal degradation of the both samples and the total weight loss of the Biofield Energy Treated sample was increased by 0.55% compared with the control sample. The DSC analysis revealed that the melting temperature of the treated sample (171.72°C) was increased by 0.21% compared with the control sample (171.36°C). The latent heat of fusion was increased by 4.66% in the treated sample compared with the control sample. This result indicated that the thermal stability of treated sample was improved compared with the control sample. The current study infers that The Trivedi Effect - Biofield Energy Healing might lead to a new polymorphic form of magnesium gluconate, which would be more soluble, bioavailable, and thermally stable compared with the untreated compound. Hence, the treated magnesium gluconate would be very useful to design better nutraceutical/pharmaceutical formulations that might offer better therapeutic responses against inflammatory diseases, immunological disorders, stress, aging and other chronic infections.

Meeti Dehran, Indu Prabha Singh, Kalyan Singh, Rabindra Kumar Singh
Circuits and Systems (CS) , 2013, DOI: 10.4236/cs.2013.46057
Abstract:

A switched capacitor biquad filter using current differencing transconductance amplifier (CDTA) is presented in this paper. The proposed circuit employs only one CDTA, two virtually grounded capacitors and one switched capacitor. It is a resistorless circuit, so it is beneficial to IC implementation in terms of space consideration. The proposed circuit is a second order single input multiple output (SIMO) current-mode filter. This filter can simultaneously realize all basic filter functions high pass, low pass and band pass responses without any component-matching conditions. All the active and passive sensitivities are low. The natural angular frequency (ω0) and quality factor (Q) of proposed filter can be electronically controlled. Owing to current mode operation it consumes less power. PSPICE simulation results are used to verify the theoretical analysis.

It has been shown in this study, through simplex process that based on the cost of the SWNT obtained by the Arc Discharge Technique, the voltage and the current should lie in the range of 30-42 V and 49-66 A, respectively. Any combination above the given values will lead to a power consumption cost beyond the final product cost in turn leading to infeasibility of the process.

Chakraborty Kalyan,Roy Aloke Kumar
Indian Journal of Dermatology , 1998,
Abstract: Twenty patients of dulusion of parasitosis received oral pimozide (PMZ) 2 mg daily for 3 months. Trihexyphenydyl hydrochloride (THP) was administered in a dose of 4 mg daily in young adults and 2 mg daily in elderly patients for prevention of extrapyramidal side effects (EPS). Within 1-2 week of initiation of therapy, sixteen patients responded completely. In four patients, dosage of PMZ had to be increased to 4 mg daily and they responded 3-4 week after initiation of therapy. Treatment was continued for 3 months and all were symptom free. Following discontinuation of therapy, delusion reappeared but disappeared after reinstitution of PMZ therapy. EPS developed in two young patients resulting in discontinuation of pimozide.

Microwave Reactors: A Brief Review on Its Fundamental Aspects and Applications  [PDF]
Kalyan Kumar Rana, Suparna Rana
Open Access Library Journal (OALib Journal) , 2014, DOI: 10.4236/oalib.1100686
Abstract: Improved laboratory protocols for convenient and rapid transformations are highly desired in modern synthetic chemistry. Microwave irradiated reactions have received considerable attention in recent years and it is a subject of intense discussion in the scientific community. Microwave heating is more efficient in terms of the energy used, produces higher temperature homogeneity and is considerably more rapid than conventional heating methods. This technique as an alternative to conventional energy sources for introduction of energy into reactions has become a recognized practical method in various fields of chemistry. Microwave-assisted organic synthesis (MAOS) is known for the spectacular accelerations produced in many reactions as a consequence of the increased heating rate, a phenomenon that cannot be easily reproduced by classical heating means. As a result, higher yields, milder reaction conditions and shorter reaction times can often be attained. Its specific heating method attracts extensive interest not only because of rapid volumetric heating, but also for suppressed side reactions, energy saving, decreased environmental pollutions and safe operations. In this review, we will try to represent an overview on origin and fundamental features of microwave ovens and its usefulness in MAOS.
