Dimerization of Butadiene with Aromatic Hydrocarbon-Sodium Complexes

Polycyclic Aromatic Hydrocarbon (PAH) formation in thermal degradation of Styrene Butadiene Copolymer (SBR)

This study has been initiated to quantify the release of the Polycyclic Aromatic Hydrocarbon (PAH) species from Styrene· Butadiene Copolymer (SBR) during gasification. The identification and quantification has been detennined experimentally using Gas Chromatography/ Mass Spectroscopy (GC/ MS) coupled to a Thenno-Gravimetric Analysis (TGA) unit. SBR samples were pyrolysed in a TGA unit in a Nz a...

Comparison of aromatic hydrocarbon measurements

Polycyclic aromatic hydrocarbon selected galaxies

Context. This is the fourth in a series of papers based on the ISOCAM Parallel Survey at 6.7 μm. While the first three papers have been devoted to active galactic nuclei (AGN), here we report on emission-line galaxies without AGN signatures in their optical spectra. Aims. Polycyclic aromatic hydrocarbon (PAH) emission has been found in both starbursts and modestly starforming galaxies, but the ...

BIVPLENT METAL COMPLEXES OF SODIUM ASCORBATE

The mode of coordination of8 manganese(fI), cobaltm, nickel(H), copper(II), zinc(H), lead(II) and cadmium(I1) to sodium ascorbate (NaHAsc) was investigated using IR, UV-visible, AAS, elemental microanalyzer, conductivity, magnetic and 'M and I3C NMR spectroscopic studies, NaNAsc is bidentate and coordination was through the carbonyl group and the oxygen atom of carbon-2 enolic hydfoxyl grou...

Biological effects of polycyclic aromatic hydrocarbon derivatives.

Polycyclic aromatic hydrocarbons (PAHs) are included in various environmental pollutants such as airborne particles and have been reported to induce a variety of toxic effects. On the other hand, PAH derivatives are generated from PAHs both through chemical reaction in the atmosphere and metabolism in the body.PAH derivatives have become known for their specific toxicities such as estrogenic/an...
