In the present study solid dispersions of the antifungal drug Ketoconazole were prepared with Pluronic F-127 and PVP K-30 with an intention to improve its dissolution properties. Investigations of the properties of the dispersions were performed using release studies, Differential scanning calorimetery (DSC), X-ray powder diffraction (XRD) and Fourier transform infrared (FTIR). The results obta...

The metallic nanoparticles have great attention of Chemists, Physists, Biologists and Engineers who wish to use them for development of new generation nanodevices. In this present study silver nanoparticles were synthesized from aqueous silver nitrate (1mM) through a simple and ecofriendly route using leaf broth of Ocimum sanctum as reductant and stabilizer. The aqueous silver ions when exposed...

Chromium doped ZnS nanocrystals with pure and 10% compositions were synthesized by chemical co-precipitation route. Samples were characterized by X-ray diffraction (XRD) technique, Fourier transforms infrared spectroscopy (FTIR) and UV-Visible spectrometer. Lattice parameter ‘a’ decreases and grain size increases with increasing Cr concentration. XRD study shows that both the samples have cubic...

This paper reports the synthesis of CeO2/ZrO2 nanocomposite by wet chemical method using cationic surfactant (CTAB). The properties of the obtained nanocomposites were analysed by X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscoy (SEM), transmission electron microscopy (TEM), UV-Diffuse Reflectance Spectroscopy (UV-DRS) and photoluminescence (PL) spectrosco...

The graft copolymerization of methacrylic acid onto gelatinized potato starch has been carried out at 70 0 C using chromic acid as initiator. The different reaction parameters such as effect of temperature, initiator and monomer concentrations were optimized to determine the maximum percentage grafting. The maximum grafting efficiency of 87.5% was optimized at reaction temperature (60 0 C), mon...

Although various kinds of carbon nitride precursors have been proposed, s-triazine-based structures are hardly reported because of their unfavorable energy, higher than that of heptazine-based ones. In this study, we investigate the thermal stability of s-triazine-based melam processed at a high pressure of 5 GPa and a temperature of 400-700 °C and complete the analyses of the composition and s...

In this research Calcium fluoride nanoparticles and its different amount of cerium ion dopant (5%and 10%) were prepared. The mentioned nanoparticle were studied by fourier transform infrared spectroscopy (FTIR) , X-ray diffraction (XRD), absorption and photoluminescence spectra (PL) and Scanning electron microscopy (SEM). The XRD patterns indicate a typical cubic fluorite structure and no other...

Nano-bioapatite (BAP) powder was successfully acquired from chicken femur bones via chemical treatment followed by calcination. The isolation of nano-bioapatite powder from chicken bone has not been published so far. The bioapatite powder was chemically and structurally characterized by elemental analysis (AAS), X-ray diffraction (XRD), transmission electron microscopy (TEM), and Fourier transf...

In this paper the procedure for the preparation of inclusion compounds of bioactive substance 2-[(2-aminoetoxy)-methyl]-4-(2-chlorophenyl)-1,4-dihydro-6-methyl-3,5-pyridine dicarboxylic acid 3-ethyl-5-methyl esterbenzene sulfonate, called amlodipine besylate with β-cyclodextrin (β-CD) and their structural characterization was described. Molecular inclusion compound of amlodipine besylate is obt...
