Gelation in Polycondensation of p-Xylylenedichloride with Aromatic Hydrocarbon

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 ...

Size and mass determination of clusters obtained by polycondensation near the gelation threshold

2014 The gelification process by polycondensation leading to self similar clusters of polyurethane is studied, near and below the gelation threshold. In dilute solutions, where light scattering experiments are performed, the interaction between clusters is a function of 03B5, the distance to the gelation threshold. This is a direct evidence of the swelling of the clusters. Thus, the experimenta...

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...
