Abstract:

Use of Vanga Bhasma can traced back from ancient era. Detailed description regarding the procedure is available in various Rasagranthas. Jarana is a special technique mentioned in recent Rasa treatises for Puti Lohas which is an intermediate stage between Shodhana and Marana. In this study, after performing both Samanya and Vishesha Shodhana, Vanga was subjected to Jarana using Ashwatha Twak as per the reference of Rasa Tarangini followed by Prakshalana to remove its alkaline nature. Later Vanga was subjected to Putapaka using Bhavana Dravya as Kumari Swarasa. Organoleptic and Elemental constitutions of both Jarita Vanga and Vanga Bhasma where analysed to see the differences and to observe the changes due to Samanya Shodhana and Vishesha Shodhana.

Abstract:

In this paper, the effect of size variation of cadmium sulphide nanocrystallites which have been prepared by precipitation method is analyzed. These prepared samples were studied using X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Energy dispersive analysis of spectroscopy (EDAX) techniques. SEM analysis represents the morphological nature of prepared samples and EDAX indicates the confirmation of elements present in the sample. XRD analysis determines the size of the samples and identifies the structure using miller indices (h k l values) of the nanocrystallies matches with JCPDS. From the XRD analysis, the size variation which depends on dopant, capping agent are discussed and corresponding results are reported in this paper.

Abstract:

IntroductionEnergy loss spectroscopy is a well known technique allowing elemental analysis in thin films. When an energy loss spectrometer is coupled with a STEM it is possible in addition to perform chemical mapping. The U314 INSERM laboratory is equipped with a C.M. 30 PHILIPS STEM coupled with an EDAX 9900 and a GATAN 666 parallel detection electron spectrometer.We describe a complete system including an additional A.T. microcomputer enabling simultaneous energy loss analysis and chemical mapping .Material and methodAn interface fitted with the bus connecting the GATAN electronics and the EDAX multichannel analyzer (MCA) allows to read the data during a photodiode read-out, and to send them via a parallel port into the host A.T microcomputer. To do this, only 18 bus lines are used and the proprietary communication protocol between the photodiode interface and the MCA is not affected. All the functions provided by the EDAX PVEELP software are preserved.

Abstract:

Macrocystis pyrifera was used for the recovery of Zn2+ and Cd2+ from slightly acidic solutions (i.e., pH 4). Sorption isotherms were obtained from mono- and bi-component solutions. For the study of metal desorption, EDTA, HNO3 and Ca(NO3)2 were used as eluents. Metal release (Ca2+, Mg2+, K+ and Na+) was monitored in order to evaluate ion exchange mechanisms. After metal sorption/desorption steps the sorbent was characterized using SEM-EDAX analysis. SEM-EDAX analysis also allowed identifying the presence of elements such as Si, Al, Co, Ag, S, P, and Fe in the cell wall. Zinc desorption was almost complete when using 0.1 M nitric acid solution and the sorbent was not significantly damaged by the acidic treatment. Cadmium was completely removed from loaded sorbent when using EDTA, but at the expense of a partial degradation of the biomass as evidenced by the decrease in the intensity of the C and O peaks (SEM-EDAX).

Abstract:

Abstract Nanoparticles (NPs) of covellite CuS have been synthesised using a modified polyol method at 160ºC - 165ºC without adding any extra surfactant. These NPs were charecterized by X-ray diffraction (XRD), Raman spectroscopy, Field Emission Scanning Electron Microscope (FESEM), Energy Dispersive Analysis of X-ray (EDAX), Zeta potential and Dynamic Light Scattering (DLS) techniques. XRD data and three Raman modes confirm P63/mmc space group and hexagonal crystal structure of CuS NPs. EDAX data of Cu:S was slight differed from nominal 1:1 ratio due to extra S taken in synthesis. FESEM images show sheet-like NPs. The zeta potential (ξ) data analysis shows that the stability of the NPs is dependent on the dispersion medium, with high stability observed above pH 8.93 in an acidic medium. At pH 10.95, a highest ξ value of -37.64 mV is recorded in de-ionized water (DIW), while the nanoparticles are found to be unstable in ethanol and propanol as dispersion mediums. According to the hydrodynamic diameter (HD) data, the particles tend to agglomerate more quickly in ethanol and propanol compared to DIW. These findings are expected to be useful in various applications such as pigments in paints, batteries, pharmaceuticals, ceramics, and waste water treatment.

Abstract:

Over the past ten years, the combination of scanning electron microscopy and energy dispersive analysis has proven to be a good and reliable tool for elemental characterization of the different components of gunshot residue. The technique evolved from a qualitative technique, involving a large amount of operator involvement, to a higher degree of quantification and automation allowing unattended analysis of gunshot residue samples.

Abstract:

Nanocrystalline ZnS and Ni doped ZnS powders were synthesized by a simple chemical co-precipitation method at room temperature using sodium sulfide and acetates of Zinc and Nickel. 2-Mercapto ethanol is used as a capping agent. Structural and optical properties of as prepared samples were characterized using X-Ray diffraction (XRD), Scanning electron microscopy (SEM), Energy Dispersive Analysis using X-rays (EDAX) and Photoluminescence studies (PL). EDAX measurements confirmed the presence of Zn, Ni and S in the prepared samples. XRD analysis reveals that the Zn1-xNixS (x= 0.00 and 0.01) nanoparticles crystallized in zincblende structure. The average particle sizes of the nanoparticles are in the range of 2-3 nm. Shifting of photo luminescence peak to higher wavelength along with intensity quenching is observed for doped ZnS nanocrystals (NCs).

Abstract:

Abstract PPy-FeWO4 composites were synthesized by polymerization of pyrrole in presence of varying weight percentage of FeWO4 nanoparticles using FeCl3 as both catalyst and dopant. The synthesized polymer composites were characterized by FTIR, XRD, FESEM-EDAX, TEM and TGA analysis. The XRD and FTIR analysis confirmed showing near pure samples were achieved. The FESEM-EDAX and TEM studies showed the presence of FeWO4 nanoparticles which were well dispersed in the polymer matrix. The thermal degradation studies showed similar stability of polymer matrix in the presence of nanoparticles. Interfacial solar water evaporation devices were fabricated by depositing the polymer composite on floatable PU sponges. The studies revealed that 50-50 wt% PPy-FeWO4 showed maximum solar to vapour conversion up to 86% with an evaporation rate up to 1.2 kg m−2 hr−1.

Abstract:

ZnO-NiO nanocomposite with epoxy coating on mild steel has been fabricated by the sol–gel assisted method. The synthesized sample was used to study corrosion protection. The analysis was performed by electrochemical impedance spectroscopy in 3.5% NaCl solution. The structural and morphological characterization of the metal oxide nanocomposite was carried out using XRD and SEM with Energy Dispersive Absorption X-ray (EDAX) analysis. XRD reveals the ZnO-NiO (hexagonal and cubic) structure with an average ZnO-NiO crystallite size of 26 nm. SEM/EDAX analysis of the ZnO-NiO nanocomposite confirms that the chemical composition of the samples consists of: Zn (8.96 ± 0.11 wt.%), Ni (10.53 ± 0.19 wt.%) and O (80.51 ± 3.12 wt.%). Electrochemical Impedance Spectroscopy (EIS) authenticated that the corrosion resistance has improved for the nanocomposites of ZnO-NiO coated along with epoxy on steel in comparison to that of the pure epoxy-coated steel.

A plate of Fe-30Cr (wt%) were subjected to isothermal furnace at 600 °C in flowing CO2 gas at total pressure of approximately 1 atm. The reacted samples morphology and microstructure were characterized by using visual inspection, optical microscope, SEM and EDAX. The weight change measurement showed a fluctuating result during the exposure. The significant weight loss was observed after five hours exposure due to oxide scale exfoliation. Formation of different oxide and element presents on the interface of the specimen such as Cr2O3, C and Fe3C were revealed by X-ray diffraction and with supported by EDAX analysis. This behavior of the high temperature corrosion on Fe-30Cr was discussed based on morphology and microstructure observation.

Abstract:

Due to low surface area and minimum possible state of energy, spherical nanoparticles are preferable over nanoparticles of other shapes. Use of nanoparticles in cancer therapy is an emerging field with wide varieties of applications. But, to retain within the cell for optimum anticancer activity, synthesized nanoparticles are required to be in proper shape and size. Plant phytochemicals reduce and cap metal ions to produce nanoparticles of different shapes and sizes. In this study, silver nanoparticles were synthesised using Ficus religiosa plant leaves aqueous extract. Synthesised material was characterised using Scanning electron microscopy (SEM), Energy dispersive X Ray analysis (EDAX), Transmission Electron microscopy (TEM) and Fourier transform infrared (FTIR) spectroscopy techniques. FTIR analysis showed presence of varied phytochemicals. SEM analysis of the sample elucidated morphological characteristics of the material while elemental analysis through EDAX technique reported silver metal ions in synthesised sample. TEM analysis confirmed nanoparticles size ranging from 21-27 nm. Result of the study showed decreased cell viability of A549 cells when treated with the green method to synthesise silver nanoparticles.

Full text

Abstract:

Resistance measurement, P–E hysteresis measurement, and transmission electron microscope and energy dispersive analysis of x-rays (TEM-EDAX) analysis were used to study the resistance failure of lead magnesium niobate-based multilayer ceramic capacitors (MLCC) under dc voltage. It was found that the failure rate of MLCC with 1/9 Pd/Ag internal electrodes was 10 times that of MLCC with 3/7 Pd/Ag electrodes after the temperature–humidity–bias test (THB). Voltage shifts of hysteresis loops showed that an internal bias field between electrodes of MLCC was formed after THB test. Ag diffusion from electrodes into the ceramics during cofiring was examined through TEM-EDAX analysis. It was also found that the degraded specimens could be partially restored after storing under natural condition. On the basis of these results, the failure mechanism was established that oxygen vacancies induced by Ag diffusion accumulated under the external bias field, which increased the concentration of electronic defects, thereby resulting in the resistance failure of MLCC.

Abstract:

Objectives: This investigation analyzes the microstructure, mechanical and corrosion characteristics of SMO 254 joints welded using constant current TIG (CCTIG) and pulse current TIG (PCTIG) with alloy 625 (ERNiCrMo-3) filler metal. Method: Optical microscopy and SEM with EDAX were employed for microstructural characterization and phase analysis. Mechanical properties were assessed through Vickers microhardness, tensile, and Charpy impact tests, followed by fracture analysis. Findings: EDAX point analysis indicates reduced Mo segregation and the absence of Nb segregation in PCTIG weldments. The overall corrosion resistance remains acceptable despite a slightly higher corrosion rate in PCTIG weldments. The study highlights the superior mechanical properties and microstructural control achieved with PCTIG welding, making it a preferable technique for SMO 254 joints. Novelty: Notably, the research establishes PCTIG as a superior method for welding SMO 254, demonstrating that it not only refines the grain structure but also significantly enhances mechanical properties, particularly toughness, by 50% compared to CCTIG.

Abstract:

Yttrium phosphate and dysprosium doped yttrium phosphate were synthesized from aqueous solutions using rare earth chloride, phosphoric acid, and traces of ammonium hydroxide. The synthesized material was then characterized for their structural investigations using powder X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM) supplemented with energy dispersive X-ray analysis (EDAX). The spectroscopic investigations were carried out using Fourier transform infrared (FTIR) spectroscopy. The thermal stability was studied using differential thermogravimetric analysis (DTA), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) techniques. X-ray diffraction analysis reveals that both yttrium phosphate and dysprosium doped yttrium phosphate belong to tetragonal system with lattice parameter Å, Å and Å, Å, respectively. The stoichiometry of the grown composition was established by energy dispersive X-ray analysis. The EDAX analysis suggests the presence of water molecules. The presence of water molecules along with orthophosphate group and metallic ion group was confirmed by FTIR analysis. Thermogravimetric analysis suggests that decomposition in case of yttrium phosphate takes place in three different stages and the final product stabilizes after 706°C, whereas in case of dysprosium doped yttrium phosphate the decomposition occurs in two different stages, and the final product stabilizes after 519°C.

Abstract:

The back-sheet shields the solar panel from UV rays, moisture, dust, and other environmental factors. With the enormous growth of the solar industry year after year, the demand for recycling is also increasing rapidly. In the present study, the back-sheet layer was extracted from a waste crystalline silicon PV module by thermally heating the module at 130˚C temperature. Various characterization techniques, including Raman, FTIR, SEM-EDAX, XRD, and TGA, were used to examine extracted back-sheet layer properties for its reuse. The Raman and FTIR spectra of extracted back-sheet are quite similar to those of reference PET back-sheet, indicating that no significant changes in composition occurred during the extraction process. The extracted back-sheet has a composition of carbon and oxygen as witnessed from EDAX spectroscopy. The extracted back sheet maintained its semicrystalline behavior as that of the reference back sheet, observed by XRD spectroscopy. Thermogravimetric analysis revealed that the thermal stability of extracted back-sheet is up to 252˚C in the air environment and up to 315˚C in the inert environment. Thermal degradation of extracted back-sheet is a two-step process in an air environment observed by differential thermogravimetry. The observed properties of extracted back-sheet are comparable to those of commercially available back-sheet, and the same may be reused in solar and polymer industries after appropriate processing.

Abstract:

Zinc oxide (ZnO) thin films are synthesized by using modified successive ionic layer adsorption and reaction techniques (SILAR) on glass substrate at room temperature. These as deposited thin films are characterized for structural, compositional, surface morphology and optical characterizations using X-ray diffraction (XRD), energy dispersive X-ray absorption spectra analysis (EDAX), atomic force microscopy (AFM) and Uv-vis absorption spectroscopy. From XRD pattern; the low intensity peaks indicate that the films consist coarsely fine grains and/or amorphous in nature. The diffraction peaks observed at 2θ = 31.71 ̊, 36.27 ̊and 56.29 ̊ are attributed to (100), (101) and (110) planes having hexagonal phase while EDAX shows elemental traces for Zn and O. Surface morphology observed from the AFM corresponds granular shape evenly distributed over substrate surface.

Abstract:

Purpose The aim of this paper is to study the hot corrosion behaviour of super 304H stainless steel for marine applications. Design/methodology/approach The investigation was carried out with three different combinations of salt mixture (Na2SO4, NaCl and V2O5) at two different temperatures (800 and 900°C). Findings The spalling and growth of oxide layer was observed more with the presence of V2O5 in the salt mixture at 900°C during experimentation than what was observed in 800°C. The mass change per unit area is calculated to study the corrosion kinetics and also the influence of salt mixture. Further, the samples are analysed through materials characterisation techniques using optical image, scanning electron microscope (SEM), energy dispersive X-ray (EDAX) and X-ray diffraction (XRD) analysis. The presence of V2O5 in the salt mixture was the most important influencing species for accelerating hot corrosion. Originality/value SEM, EDAX and XRD analysis confirmed the formation of Fe2O3 and Cr2O3 at 900°C showing contribution in corrosion protection.
