The liquid-liquid extraction of neodymium(III) from succinate media (0.06M) has been studied at pH 6.0 with the solution of 0.1M of N-n-octylaniline in xylene when equilibrium is maintained for 5min. The back-extraction of neodymium(III) has been performed by using 0.1M HClO4. The effect of various parameters, such as pH, equilibrium time, extractant concentration, stripping agents, organic diluents, and aqueous to organic volume ratio on the extraction of neodymium(III) has been studied. On the basis of slope analysis, the stoichiometry of the extracted species was determined as 1: 1: 2 [RR′NH2 + Nd (succinate)2 -](org). The method is free from interference of large number cations and anions. The method was used for the selective extraction of neodymium(III) from its binary mixture with U(VI), Zr(IV), Nb(V), La(III), Th(IV), Ce(IV), and Y(III). The proposed method is selective and was successfully applied to the synthetic mixtures to show the practical utility of the extractant. © 2012 Balasaheb N. Kokare et al. Source

A pure-phase anatase nanocrystalline TiO2 has been prepared at lower temperatures from aqueous peroxy titanium complex solution using titanium (III) chloride as precursor. The study on the reflux method has been carried out to investigate the effect of refluxing conditions on the characteristic properties of TiO2 and it has shown significant effects on the final product. The X-ray diffraction and UV-vis characterisations reveal that as refluxing time extended, the crystallite size increased and variation is found in bandgap energies. This is attributed to the effect of refluxing during the synthesis of nanocrystalline TiO2. A detailed study on the reflux method used for the synthesis of nanocrystalline TiO2 is reported. © The Institution of Engineering and Technology 2011. Source

Dysprosium doped Co-Zn ferrites were synthesized by sol-gel auto combustion method. These synthesized compounds were characterized by using XRD, SEM, FTIR, EDS, TGA-DTA and TEM. TGA weight loss in the region of 100-200°C and this loss is due to autocatalytic oxidation reduction reactions of nitrates with glycine. The composition Co 0.5Zn 0.5Fe 2-xDy xO 4 (x=0.075) shows fibrous reticulated mesh like morphology. The average grain size increases with increasing the Dy content in the Co-Zn ferrite. The XRD study of Dy doped Co-Zn ferrite shows in Cubic spinel phase. Particle size obtained from TEM analysis was found to be 30-40 nm. The FTIR spectra showed the characteristic of two strong absorption bands at 560 cm -1 corresponds to intrinsic stretching vibrations of the metal at the tetrahedral site and lowest band is observed at 455 cm -1 corresponds to octahedral site. © 2012 Elsevier B.V.

Objective: The aim of current work was to assess the total phenolic content (TPC), total flavonoid content (TFC), phenolic compounds and antioxidant properties of different extracts of four Cheilanthes sp.: Cheilanthes farinosa (Forssk.) Kaulf, Cheilanthes anceps Sw, Cheilanthes tenuifolia (Burm.f.) Sw, and Cheilanthes albomarginata Clarkewhich is collected from Northern Western Ghats of India. Methods: Analysis of the scavenging activity using 1, 1-diphenyl-2-picrylhydrazyl (DPPH), ferric reducing power assays and N, N-dimethyl-p-phenylendiamine (DMPD) radical cation decolorization assay. Results: Cheilanthes sp.whole plant with rhizome was analyzed for total flavonoids content (TFC) and phenolic content (TPC). The ethyl alcohol and water are the best solvents for the extracting phenols and flavonoids from the Cheilanthes sp. whole plant with rhizome (CSWPR).The antioxidant activities of Cheilanthes sp. whole plant with rhizomeextracts were a positive correlation between total flavonoids and phenolic content capacity and observed DPPH radical scavenging activity based on these results, the result signifies that the potentiality Cheilanthes sp. whole plant with rhizomeis one of the natural sources of antioxidant compounds. Conclusion: We have reported in thisstudy the cheilanthes species from whole plant with rhizome powder possess good antioxidant properties as well as their potential antioxidant capacity against DPPH radical, ferric reducing power and DMPDradical. Cheilanthes species whole plant with rhizome is a rich source of Phytochemicals including total antioxidant and phenoliccompounds and it offers to the development of value-added products from Cheilanthes species wholeplants so enhance today's opportunities in nutraceuticals and food applications for Human Health. © 2016, Asian Journal of Pharmaceutical and Clinical Research.

Objective: The present study was for the determination of bioactive volatile compounds from chloroform and ethanolic extract. Methods: For present investigation of the samples were carried out by using Shimadzu Make QP-2010 with nonpolar 60 M RTX 5MS Column. Interpretation on Mass-Spectrum GC-MS was conducted using the database of National Institute Slandered and Technology (NIST) having more 62,000 patterns. Results: In Ethanolic extract seven compounds and chloroform extract fourteen compounds were identified. The common compounds in these two extracts are Germacrene D; 1, 3-cyclohexanedione, 2-methyl-2 (3-Oxobutyl); Neoisolongifolene, 8, 9-dehydro. Coclusion: Present investigation emphasizes the efficacy of traditional remedies and that it inspires the people to realize the importance of natural resources for its potent pharmaceutical use. © 2015, Asian Journal of Pharmaceutical and Clinical Research.
