Glycine doped potassium thiourea chloride (PTC) crystal has been grown by slow solution evaporation technique. The dielectric studies have been employed to examine substantial improvement in dielectric constant and dielectric loss of glycine doped PTC crystal. The etching studies have been performed to investigate the surface quality of this crystal. The Z-scan studies have been carried out at 632.8 nm to explore the third order nonlinear optical nature. The negative nonlinear refraction of glycine doped PTC crystal was found to be of 7.27 × 10-12 cm2/W. The origin of high magnitude of third order nonlinear optical susceptibility and reverse saturable nonlinear absorption have been investigated. The obtained results were explored to discuss the nonlinear optical applications of PTC crystal. © Wroclaw University of Technology.

The present article is focused to investigate the influence of L-cystine (LC) on linear-non-linear optical and laser damage threshold of cadmium thiourea acetate (CTA) crystal. The structural parameters of pure and LC doped CTA crystals have been determined using the single crystal X-ray diffraction technique. The functional groups of grown crystals have been identified by means of fourier transform infrared (FT-IR) analysis. The UV–visible spectral analysis has been done in the range of 200–900 nm to ascertain the uplifting influence of LC on optical properties of CTA crystal. The second harmonic generation (SHG) efficiency of LC doped CTA crystal is found to be higher than CTA and KDP crystal. The Z-scan technique has been employed to determine the third order nonlinear optical (TONLO) nature of LC doped CTA crystal at 632.8 nm. The self focusing tendency confirmed the strong kerr lensing ability of LC doped CTA crystal. The TONLO susceptibility (χ3), refraction (n2) and absorption coefficient (β) has been calculated using the Z-scan data. The laser damage threshold of pure and LC doped CTA crystals has been measured using the Q-switched Nd:YAG laser and its is found to be in range of GW/cm2. The surface analysis has been done by means of etching studies. © 2016 Elsevier Ltd

Ferrite of system, namely Ni1-xZnxFe 2O4 with x = (0.0, 0.2, 0.4, 0.6, 0.8, 1.0), have been prepared by solid state reaction to investigate the effect of gamma rays irradiations using Co60 source on the cation distribution, structural and magnetic properties. The unirradiated and irradiated samples were then subjected to characterization techniques such as X-ray diffraction, magnetization and AC susceptibility. The results of these characterizations are found to be different for irradiated from that of the pristine sample. The modifications in respect of irradiated samples are explained in terms of the ion-induced disorder. The important result of γ-irradiation on the cation distribution, structural and magnetic properties is the change of ratio Fe 2+/Fe3+. Possible reasons on the results are proposed. © 2010 Published by Elsevier B.V.

In current study doping of glycine (G) in potassium thiourea chloride (PTC) crystal has been firstly achieved and glycine doped PTC (G-PTC) crystal has been grown by slow solution evaporation technique. The unit cell parameters of crystals have been determined by means of single crystal X-ray diffraction technique. The functional groups of pure and G-PTC crystal have been identified using Fourier transform infrared analysis. In UV-visible studies, the increased optical transparency of G-PTC crystal has been measured within 200-900 nm and the optical constants have been determined using the transmittance data. The Kurtz and Perry test has been performed to confirm the enhancement in second harmonic generation (SHG) efficiency of G-PTC crystal as compared to KDP and PTC crystal. The temperature dependent dielectric analysis has been carried out to investigate the dielectric constant and dielectric loss of grown crystal. The thermal stability of the grown crystal has been determined using the thermogravimetric analysis. © 2016 Elsevier GmbH. All rights reserved.

Background: Diacerein and aceclofenac drug product combination is used for the pain management in osteoarthritis. The main aspects of the present study is to develop stability indicating, sensitive reverse phase high-performance liquid chromatographic method for the simultaneous determination of diacerein and ceclofenac in tablet dosage form. Were, the chromatographic separation was achieved on Kromasil C-18, 150 × 4.6 mm, 3.5-μm analytical column using mobile phase double distilled water (pH 2.7 with glacial acetic acid)-acetonitrile (45:55 v/v). Detector was set at 256 nm. Results: The described method shows excellent linearity over a range of 75–2.5 μg/mL for diacerein and 150–5 μg/mL for aceclofenac. The correlation coefficient for diacerein is 0.9999 and for aceclofenac is 0.9997. Conclusions: The proposed method was found to be suitable for simultaneous determination and stability study of diacerein and aceclofenac in tablet dosage form. © 2012, Shaikh et al; licensee Springer.

The ground water samples from three different locations were analysed regularly in every month for its Temp, pH, TDS, conductivity NO2, SO4, PO4, DO, Hardness, chlorides, CO2, MPN, Na+, K+ and COD. All values were found to be within permissible limit, except for COD. The values of COD were found to be high. The results reveal that no specific trend can be predicted for seasonal variation at the three stations. The values depend on location of site, its surrounding, depth of ground water tables, geothermal process etc. © Research India Publications.

The knowledge of biochemical compositions f any edible organism is extremely important. Since the nutritive value is reflected in its biochemical content. Lipid storage is advantageous to organisms since it can deliver eight times more calories per unit weight of energy to that from carbohydrates. During reproductive seasons lipids along with glycogen are channelled towards the gonads to meet the cost of active gametogenesis in crustaceans. The present study shows that the lipid content of Barytelphusa cuncularis to be more in gonads during winter (gonadal growth stage) and least during summer (spent stage).

Active pharmaceutical intermediates (API) in waste waters have adverse effects on aquatic life and environment. The API have high COD value and low BOD3 and hence difficult to treat biologically. In this study, advanced oxidation processes (AOPs) utilizing the H2O2/Fe+2, Fenton reactions were investigated in lab-scale experiments for the degradation of Atenolol containing waste water streams. The experimental results showed that the Fenton process using H2O2/Fe+2 was the most effective treatment process. With Fenton processes, COD reduction of wastewater can be achieved successfully. It is suggested that Fenton processes are viable techniques for the degradation of Atenolol from the waste water stream with relatively low toxic by-products in the effluent which can be easily biodegraded in the activated sludge process. Hence, the Fenton process with H2O2/Fe+2 is considered a suitable pretreatment method to degrade the active pharmaceutical molecules and to improve the biodegradability of waste water. © 2011.
