Applied Spectroscopy Reviews | Year: 2017

With the constant rising demand for pure water to meet the needs of the growing population particularly in developing countries, fluoride remediation from drinking water has emerged as an increasingly important matter of public concern. In the past decade, significant efforts and advances have been made for developing efficient adsorbents for fluoride removal from water. This review summarizes recent advances (2012–2016) in defluoridation techniques and highlights the challenges and opportunities for future research in the important field of fluoride removal. The spectroscopic techniques, used to develop adsorbents/adsorption mechanism, discussed in this review are X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, inductively coupled plasma mass spectrometry, atomic absorption spectrometry, inductive coupled plasma-optical emission spectroscopy, and X-ray photoelectron spectroscopy. The defluoridation techniques have been discussed in four categories: precipitation, membrane, ion-exchange, and adsorption techniques. Then recent research on fluoride removal using various adsorbents with their spectroscopic studies are summarized and discussed with regard to their synthetic chemistry, properties, and applications. The advantages and disadvantages of defluoridation techniques and adsorbents have been presented. Finally, the future needs and perspectives of fluoride removal are addressed. © 2017 Taylor & Francis Group, LLC.

Ethnopharmacological relevance The genus Anogeissus (axlewood tree, ghatti tree, button tree and chewing stick tree) belongs to Combretaceae, includes eight species that are distributed in Asia and Africa. Plants are used as an ethnomedicine in Asia and Africa to treat various ailments like diabetes, fever, diarrhoea, dysentery, tuberculosis, wound healing, skin diseases (eczema, psoriasis), snake and scorpion venom. Based on the traditional knowledge, different phytochemical and pharmacological activities have been at the focus of research. The aim of this review is to provide updated, comprehensive and categorized information on the ethnobotany, phytochemistry, pharmacological research and toxicity of Anogeissus species in order to identify their therapeutic potential and directs future research opportunities. Materials and methods The relevant data was searched by using the keyword “Anogeissus” in “Scopus”, “Google Scholar”, “Web of Science”, “PubMed”, and “ScienceDirect” databases. Plant taxonomy was validated by the databases “The Plant List” and A.J. Scott, 1979. Results This review discusses the current knowledge of the ethnobotany, phytochemistry and in vitro as well as in vivo pharmacological evaluations carried out on the extracts and isolated main active constituents of Anogeissus genus. Among eight species, most of the phytochemical and pharmacological studies were performed on four species. About 55 secondary metabolites are isolated from the genus. Stem bark, leaf, seed, fruit, root of the plants are used for the treatment of several health disorders such as diabetes, fever, diarrhoea, dysentery, tuberculosis, wound healing, skin diseases (eczema, psoriasis), snake and scorpion venom. Gum ghatti obtained from Anogeissus latifolia is used after delivery as tonic and in spermatorrhoea. Many phytochemical investigations on this genus confirmed that it is rich in phenolic compounds. Modern pharmacology research has confirmed that the crude extracts or the isolated active compounds of the genus Anogeissus possess antioxidant, antimicrobial, wound healing, antiulcer, anti-inflammation, anti-diabetics, hepatoprotective, hypolipidemic, antiparasitic and neuroprotective effects. Conclusions This review confirms that some Anogeissus species have emerged as a good source of the traditional medicine for wound healing, inflammation, skin diseases, microbial infection and diabetes. Many traditional uses of Anogeissus species have now been validated by modern pharmacology research. Intensive investigations of all the species of Anogeissus regarding phytochemical and pharmacological properties, especially their mechanism of action, safety and efficacy could be the future research interests before starting clinical trials. © 2016 Elsevier Ireland Ltd

An object representation of the open scene exists in the 3D form and to represent it on 2D plane or paper, reliable transformation is required. In this paper, a fuzzy rule integrated genetic modeling is provided for the 2D graph formation. The fuzzy rule definition is here applied on visibility, distance from the convex hull and cross point frequency. The population set for graph transformation is generated by setting the connecting vertex count. This population set is supplied to genetic process for early phase fitness formulation with length, distance and density parameters. While generating the new derived updated, the fuzzy rules are applied. This fuzzy rule is based on cross point and visibility distance observations. The experimental applies to multiple larger 3D graphs. The obtained results show that the model has provided the significant network generation in optimized time frame and provided the effective surface derivation. © 2016 IEEE.

As the people are shifting from offline to online in every perspective of life, the dependency on Web Applications is becoming rampant. Web Applications serve the people by easing their tasks. There are ample web applications distributed over the internet. But what matters a lot is the performance shown by them. Performance means the request response time, page load time, etc. In this paper we have discussed the behavior of MVC architecture based on PHP and.NET framework. The comparison helps us to distinguish among them that which technology performs better. We have used one Web Application testing tool. This tool helps us to evaluate the web application based on various metrics. © 2016 IEEE.

Carbon nanotubes (CNTs) were synthesized by the floating catalytic chemical vapor deposition technique using ferrocene in benzene as the hydrocarbon source. The functionalization of CNTs was carried out by oxidation (CNT-OX) and grafting with a tributyl phosphate (TBP) ligand (CNT-TBP). Various spectroscopic techniques including scanning electron microscopy (SEM), Fourier Transform Infra Red Spectroscopy (FTIR), BET surface area and X-ray photoelectron spectroscopy (XPS) were used to characterize the adsorbents. FTIR and XPS studies revealed the efficient grafting of the TBP ligand on the CNT surface. The effect of the initial pH and the contact time for the maximum adsorption of U(vi) with CNT-plain, CNT-OX and CNT-TBP was studied. The spontaneity of the sorption was confirmed by thermodynamic data. A pseudo second order model with a regression coefficient of >0.978 was obtained for CNT-TBP and equilibrium was reached within 3 h. The Langmuir maximum adsorption capacity of U(vi) at pH 5 for CNT, CNT-OX and CNT-TBP was found to be 66.6, 100.0 and 166.6 mg g-1 respectively. Using 0.1 M HCL as a desorbent, recyclability studies were carried out for three cycles. The probable mechanism of adsorption between U(vi) and CNT-TBP could be understood through FTIR and XPS techniques. © The Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2016.

The ab initio calculations were performed for CdGeP2 chalcopyrite in the body centered tetragonal (BCT) phase in an attempt to calculate the structural, electronic and optical properties by linearized augmented plane wave (LAPW) method as implemented in the WIEN2K. Furthermore, optical features such as dielectric functions, refractive indices, extinction coefficient, optical reflectivity, absorption coefficients, optical conductivities, were calculated for photon energies up to 40 eV. The six elastic constants (C11, C12, C13, C33, C44 and C66) and mechanical parameters were presented and compared with the available experimental data. The thermodynamic calculations within the quasi-harmonic approximation is used to give an accurate description of the pressureerature dependence of the thermal-expansion coefficient, bulk modulus, specific heat, Debye temperature, entropy and Grüneisen parameters. Based on the semi-empirical relation, we have determined the hardness of the materials for the first time at different pressure (0-8 GPa) and temperature (0-1000 K). Further, CdGeP2 solar cell devices have been modeled; device physics and performance parameters are analyzed for zinc chalcogenides (ZnX; X=S, Se, Te) buffer layers. Simulation results for CdGeP2 thin layer solar cell show the maximum efficiency (22.6%) with ZnSe as the buffer layer. © 2015 Elsevier Ltd. All rights reserved.

Abstract First principles calculations were performed by the linearized augmented plane wave (LAPW) method as implemented in the WIEN2K code within the density functional theory to obtain the structural, electronic and optical properties for CdSnP2 in the body centered tetragonal (BCT) phase. Furthermore, optical features such as dielectric functions, refractive indices, extinction coefficient, optical reflectivity, absorption coefficients, optical conductivities, were calculated for photon energies up to 40 eV. The six elastic constants (C11, C12, C13, C33, C44 and C66) and mechanical parameters were presented and compared with the available experimental data. The thermodynamic calculations within the quasi-harmonic approximation is used to give an accurate description of the pressure-temperature dependence of the thermal-expansion coefficient, bulk modulus, specific heat, Debye temperature, entropy and Grüneisen parameters. Further, CdSnP2 solar cell devices have been modeled; device physics and performance parameters are analyzed for zinc chalcogenides (ZnX; X = S, Se) buffer layers. Simulation results for CdSnP2 thin layer solar cell show the maximum efficiency (15.15%) with ZnSe as the buffer layer. Most of the investigated parameters are reported for the first time. © 2015 Elsevier Ltd.

We have performed ab-initio calculations for the structural, electronic, optical, elastic and thermal properties of the copper gallium chalcopyrite (CuGaSe2). The Full Potential Linearized Augmented Plane Wave (FP-LAPW) method is used to find the equilibrium structural parameters and to compute the full elastic tensors. We have reported electronic and optical properties with the recently developed density functional of Tran and Blaha. Furthermore, optical features such as dielectric functions, refractive indices, extinction coefficient, optical reflectivity, absorption coefficients, optical conductivities, are calculated for photon energies up to 30 eV. The thermodynamical properties such as thermal expansion, heat capacity, Debye temperature, entropy and Grüneisen parameter, bulk modulus and hardness are calculated employing the quasi-harmonic Debye model at different temperatures (0-1200 K) and pressures (0-8 GPa) and the silent results are interpreted. To check the potentiality of CuGaSe2 as future solar cell material, device modeling and simulation studies have been carried out with a variety of buffer layers over CuGaSe2 absorption layer. The band diagram and J/V curves are analyzed and device performance parameters i.e. efficiency, open circuit voltage, short circuit current, quantum efficiency are calculated for CdS, ZnS and ZnSe buffer layers. Simulation results for CuGaSe2 thin layer solar cell show the maximum efficiency (15.8%) with ZnSe as the buffer layer. Most of the investigated parameters are reported for the first time. © 2015 Elsevier Ltd. All rights reserved.
