Abstract: Present study shows synthesis of Tin Oxide (SnO2) nanoparticles by simple precipitation method at room temperature. SnO2 nanoparticles were synthesized by using hydrated stannic chloride (SnCl4..5H2O) as precursor and sodium carbonate as precipitating reagent. Triton X-100 and Lauryl alcohol were used as surfactants. The precipitate was calcinated at 3250C for one hour. The size of the as prepared particles of SnO2 with and without surfactants was estimated using X-ray diffraction(XRD). The particle sizes with surfactants are found to be less than that without surfactants.

Keywords: Co-precipitation Tin Oxide nanoparticles, SnO2 with surfactant

Abstract: Semi empirical quantum mechanical calculations were carried out on the most stable structure for calculating the vibration frequencies and IR absorption intensities for normal coordinates of the cyclacene named mono (C56H28) and Carbon nanotube named tetra (C140H28)– ring layer of (7,7) armchair single wall carbon nanotube (SWCNTs) at their equilibrium geometries which were all found to have D7d symmetry point group. Assignment of the modes of vibration (3N-6) was done depending on the pictures of their modes by applying (Gaussian 03) program. Comparison of the vibration frequencies which are active in IR spectra of the two molecules. , the results showed that C-H stretching vibration frequencies value increased with increased of length nano tube (rings layer SWCNT).

Abstract: The inhibitive action and adsorption character of water extract of Solanum melongena (SM) on mild steel in 0.5 M H2SO4 was investigated using gravimetric and electrochemical techniques. The results revealed that the water extract of SM effectively inhibited mild steel corrosion in 0.5 M H2SO4 environment, with the effect becoming more vivid as water extract of SM extract concentration increased and as immersion time lengthened, from the polarization results, water extract of SM was seen to reduce the cathodic and anodic reactions as a result of the adsorption of the organic species from the extract on the metal/solution interface. Experimental data was seen to fit the Langmuir isotherm, the result obtained showed that water extract of SM could serve as an effective corrosion inhibitor for mild steel in 0.5 M H2SO4.

Abstract: In recent years, polymeric materials from renewable resources have received significant research attention because of their importance in environmental and economic viewpoints. Inexpensive triglyceride plant oils have been used for the production of biodegradable polymeric materials. Polymeric nanocomposites were synthesized from epoxidized castor oil-based polymer and montmorillonite (MMT) clay using an in situ polymerization reaction. The resultant nanocomposites were characterized using FTIR, XRD andSEM analysis. It was found that the desired polymer nanocomposite structure was achieved when the OMMT was loading at 1, 2and 3 wt%. All the nanocomposites were found to have improved mechanical properties as compared with ordinary polymer, which have been confirmed by mechanical analysis.

Abstract: The kinetics of oxidation of L-Leucine by cerium (IV) in presence of catalytic amount of potassium (K+) in acid medium has been studied significantly in the temperature range of (300-315) K. The reaction proceeds through the formation of an intermediate complex formation followed by the radical formation mechanism. The reaction followed first order kinetics with respect to L-Leucine, inverse order with respect to Ce(IV), and a positive fractional order with respect to potassium(K+). The major oxidation products are identified by spot test and FT-IR. The polymerization of acrylonitrile indicates the generation pf free radicals in the reaction system. A suitable mechanism has been proposed for the above reaction.

Abstract: Mixed ligand complexes of Mn(II) ion with some heterocyclic nitrogen bases and 1-cyano-1-carboethoxyethylene-2,2-dithiolate ion (CED2-) of the compositions, Mn(N-N)n(CED) and Mn(N-N)(CED)L2 [N-N = o-phen, n =2 or 3, CED2- = 1-cyano-1-carboethoxyethylene-2,2-dithiolate, L = H2O, pyridine (py), α-picoline (α-pic), β-picoline (β-pic) or γ-picoline (γ-pic)] have been isolated and characterized on the basis of analytical data, molar conductance, magnetic susceptibility, electronic and infrared spectral studies. The molar conductance data reveal non-electrolytic nature of the complexes in DMF. Magnetic moment values suggest high spin complexes. The electronic spectral data suggest octahedral stereochemistry around Mn(II) ion in these complexes. Infrared spectral studies suggest bidentate chelating behaviour of CED2- , 1, 10-phenanthroline while other ligands show unidentate behaviour in their complexes.

Keywords: Manganese (II), 1-cyano-1-carboethoxyethylene-2,2-dithiolate, Nitrogen donors, Mixed ligand complexes.

Abstract: A novel, simple, sensitive and rapid spectrophotometric method has been developed for the estimation of Gemifloxacin (GEM), Moxifloxacin (MOX), Tramadol (TRA) and Trimetazidine (TRI). The present spectrophotometric method is based on the bromination of the drug with a known excess of the bromate– bromide mixture under acidic conditions followed by the estimation of the surplus bromine by reaction with Methyl Orange dye, and measuring the absorbance at 508 nm. Beer's law was obeyed in the concentration range of 5-35μg/ml, 1.5-10.5 μg/ml, 3-30 μg/ml and 2.5-10 μg/ml for GEM, MOX, TRA and TRI respectively. The method was validated for accuracy, precision and recovery studies. Statistical analysis proved the method was Precise, reproducible, selective, specific, and accurate for analysis of GEM, MOX, TRA and TRI. The wide linearity range, sensitivity, accuracy, and simple procedure imply that the proposed technique demonstrated to be appropriate for routine analysis and quality control assays of tablets.

Abstract: This work aims at study the antioxidant activity of oils extracted using hexane and ethanol from the seeds of two types of red onion in Morocco, using the method of trapping the free radical DPPH° (2,2-diphenyl-1 picrylhydrazyl). This study was carried out by comparing it to a natural antioxidant ascorbic acid. Both ethanol extracted from the sample of Doukkala (EED) and sample Tetouan (EET) respectively show an effective concentration IC50 33.63 g / ml and 34.20μg / ml compared to the IC50 ascorbic acid, which is 10.79 g / ml with a reaction time reaches equilibrium TEC50 in 5 minutes, while the effective concentrations of EHD and EHT extracts have as IC50 values 54.40μg / ml and 57.11μg / ml. These results were confirmed by calculating the percentage of the anti-radical efficiency which shows that the EED and EET extracts possess anti-radical efficiency 11% higher than the EHD and EHT extracts (5%) are six times lower than that of ascorbic acid (69%).
