X-ray diffraction methods are used routinely to identify detrital and authigenic minerals in bulk powders of marine sediment. Semiquantitative bulk XRD analysis, however, is difficult. We employed a mathematical technique using matrix singular value decomposition to solve for reliable normalization factors, thereby allowing accurate conversion of XRD data to relative mineral abundances. Calibra...

zinc oxide nanotubes were prepared by a hydrothermal method using zinc nitrate as a precursor. The synthesized nanotubes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) and their optical properties were characterized using UV -visible spectroscopy. The XRD analysis confirme...

Palladium nanoparticles of average size around 8 nm have been synthesized rapidly by UV irradiation of mixture of palladium chloride and potassium oxalate solutions. A rod-shaped palladium oxalate complex has been observed as an intermediate. In the absence of potassium oxalate, no Pd nanoparticles have been observed. The synthesized Pd nanoparticles have been characterized by powder X-ray diff...

p-Chlorobenzophenone (p-CBP) is the important chemical intermediate used for the synthesis of several pharmaceutical drugs like fenofibrate, cetirizine, alprazolam, and benzodiazepine. The aim of this study was set to evaluate the impact of biofield energy treatment on physicochemical and spectroscopic properties of p-CBP. The study was accomplished in two groups i.e. control and treated. The t...
