X-Ray Crystal and Molecular Structure Determination of Coumarin Derivatives - A Comparative Study[ ]


Coumarin is the simplest member of the group of oxygen heterocyclic compounds called benzo-2-pyrones. Coumarins are an important class of compound due to their presence in natural products as well as their medicinal applications, e.g. as anti-inflammatory, anti-viral, antioxidant, antibacterial, antifungal, anti-HIV and as anti-carcinogenic agents.

Effect of Amino Acid (L-Phenylalanine) on Growth and Characterization of Potassium Hydrogen Phthalate Crystals[ ]


Single crystals of Potassium Hydrogen Phthalate doped with L-Phenylalanine were grown by slow evaporation technique. The grown crystals were subjected to powder XRD analysis, and the results confirm its structure and lattice parameters. The Fourier Transform confirms the incorporation of L-Phenylalanine in to KHP crystal. The optical transparency of the grown crystal was studied by UV-Visible spectroscopy. Mechanical strength of the grown crystal was estimated by Vickers hardness Test. Both dielectric constant and dielectric loss decreases with increase in temperature at constant frequency.

Ab initio and density functional study of barrier heights of methyl group torsion and hyperconjugation in 1,2,3,5-tetramethylnaphthalene[ ]


Toxic, mutagenic and carcinogenic effects among tetramethylnaphthalene (TMN) may differ considerably and for that reason it is important to identify all changes in their structures. We have reported the results of ab initio and DFT calculations of equilibrium molecular geometry, vibrational spectrum and assignments in the ground electronic state of 1,2,3,5-tetramethylnapthalene(1,2,3,4-TMN). The structural parameters of 1,2,3,5-tetramethylnapthalene are analyzed and compared with those of the naphthalene molecule.

Studies on growth, structural, optical, etching and nonlinear optical a properties of L-arginine maleate dihydrate single crystal for NLO application[ ]


Single crystal of L-arginine maleate dihydrate (LAMD) was grown by slow evaporation solution technique (SEST) at a constant temperature of 40°C. The crystallinity of grown single crystal was confirmed by powder X–ray diffraction (PXRD) analysis. The strain in the lattice of the material was calculated using Hall-Williamson co-efficient relation for the first time.

Synthesis, growth, structural, optical, mechanical and dielectric properties of an organic crystal: 1H-Benzimidazolium Hydrogen tartrate[ ]


1H-Benzimidazolium Hydrogen tartrate (BMZHT) were grown from mixture solvent (methanol and water) using slow evaporation solution growth technique. The solubility of BMZHT was found out. The lattice parameters of the grown crystal were found from single crystal XRD analysis. The Functional groups present in BMZHT single crystal were analysed using FTIR measurements. The cut off wavelength is identified from UV-Vis spectrum.

EFFECT OF IRON DOPING ON STRUCTURAL AND OPTICAL PROPERTIES OF TIO2 THIN FILM BY SOL-GEL SPIN COATING TECHNIQUE[ ]


Thin films of iron (Fe) doped titanium dioxide (Fe:TiO2) were prepared on a glass substrate by sol-gel spin coating technique and further calcined at 450ï‚°C. The Structural and optical properties of Fe doped TiO2 thin films were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible spectroscopy (UV-vis) and Atomic force microscopic (AFM) techniques.

Synthesis and Characterisation of Pure and Doped Hydroxyapatite Nano Powders by Sol Gel Method[ ]


Hydroxyapatite (Ca10(PO4)6(OH)2) is the main inorganic component of human bones and teeth, showing a very good biocompatibility, bioactivity and osteoconductivity due to its nontoxic, and noninflammatory properties. Nanostructured Hydroxyapatite is extensively employed in orthopedics and dentistry the world over. Biological and physicochemical properties of HA can be improved by the substitution with ions usually present in natural apatites of bone.

Synthesis and characterization of fruit mediated silver nanoparticles using tamarindus indica fruit extract[ ]


The production of silver nanoparticles by chemical and physical methods is expensive and the reagents used are deleterious. Green syntheses of silver nanoparticles have more attention due to their eco-friendliness, least toxicity and cost effective. Tamarindus indica fruit was selected, because of its low cost, easily available and medicinal value. Silver nanoparticles are prepared using aqueous silver nitrate with tamarindus indica fruit extract as reducing and stabilizing agent.

INHIBITING EFFECT OF N,N-METHYLENE BIS ACRYLAMIDE ON ALUMINIUM CORROSION IN 0.3M HYDROCHLORIC ACID SOLUTION[ ]


Aluminium (Al) and its alloys are widely used in many industries such as reaction vessels, pipes, machinery and chemical batteries because of their light weight, high thermal and electrical conductivity as well as high resistance to corrosion in a wide variety of corrosive environments and low cost. Generally, the corrosion resistance of metals, such as Al in corrosive environments, may be attributed to the formation of a protective tightly adhered invisible oxide film on the metal surface. The film reduces the corrosion of such metals.
