A method for the preconcentration of Au (III), Pd (II) and Cu (II) is proposed using a minicolumn filled with silica gel modified by 3-[2-(2-aminoethylamino)ethyl-amino]propyl group (AEAEAP-SG). The retained analytes on ...
A simple and enviromentaly benign method for synthesis of flavones is described via dehydrative cyclisation of o-hydroxydibenzoylmethane using silica gel supported NaHSO4 catalyst.
The classical boundary condition of fluid dynamics, i.e. the no-slip condition is violated during the flow of various complex fluids including polymer melts and polymeric suspensions. It is recognized that the dynamics of ...
Crystallographic studies have shown that the oxidation of 3 beta,6 beta-dihydroxy-5 beta-methyl-19-norsteroidal 9(10)-alkenes with chromium trioxide leads to 9 alpha,10 alpha-epoxides as minor products.

Information on atmospheric dust deposition is important for various types of research, including urban runoff and air quality modelling, ecosystem nutrient cycling and epidemiological studies. This paper presents heavy ...
Optical characterization of the charge transfer complex of 2,9,16,23-tetra neopentoxyphthalocyaninatozinc(II) with 2,3-dichloro-5,6-dicyano p-benzoquinone (DDQ) has been carried out using the transmittance T(lambda) and ...
The simultaneous spectrophotometric determination of ascorbic acid (AA) and acetylsalicylic acid (ASA) in effervescent tablets in the presence of the overlapping spectra was accomplished by the continuous wavelet transform ...
In the title compound, C10H7Br5O, prepared by bromination of 5- methoxyindane, all bond lengths and angles are in the usual ranges. However, the relatively wide range of Br - C - C angles [ 107.2 ( 5) - 117.0 ( 4)degrees] ...
