Flame retardants (FRs) are used in many consumer products for fire safety reasons. Their use children’s car seats may result and vehicle occupants’ exposure to these compounds including inhalation through poor air quality. We have tested several from local retailers the presence of FRs. A number organophosphorus flame (OPFRs) were identified extracts (dichloromethane) eight foam materials taken...

California's furniture flammability standard Technical Bulletin 117 (TB 117) is believed to be a major driver of chemical flame retardant (FR) use in residential furniture in the United States. With the phase-out of the polybrominated diphenyl ether (PBDE) FR mixture PentaBDE in 2005, alternative FRs are increasingly being used to meet TB 117; however, it was unclear which chemicals were being ...

A series of new tetrasubstituted imidazoles 2-phenyl-3-(1, 4, 5-triphenyl-1H-imidazol-2-yl)-1H-indole derivatives substituted with –F, Cl, Br, I,-OCH3 and -NHCOCH3 were synthesized using a multicomponent reaction. The compounds were obtained in good yields by easy workup and with high purity

The title complex, [Cu(3)WBrOS(3)(C(18)H(15)P)(3)], a neutral heavily distorted cubane-like W/S/Cu cluster, was self-assembled from ammonium trithio-tungstate(VI), cuprous bromide and triphenyl-phosphane in N,N-dimethyl-formamide. The average Cu-Br, Cu-S and W-μ(3)-S bond lengths are 2.731 (2), 2.318 (2) and 2.256 (2) Å, respectively, in the distorted cubane-like skeleton. The W atom exhibits t...

Perylene bisimide and triphenyl diamine are prototypical organic dyes frequently used in organic solar cells and light emitting devices. Recent Forster-resonant-energy-transfer experiments on a bridged organic dyad consisting of triphenyl diamine as an energy-donor and perylene bisimide as an energy-acceptor revealed a strong fluorescence quenching on the perylene bisimide. This quenching is ab...

In recent years, the linear economic model and global warming have shown that it is necessary to move toward a circular model. this scenario, recycling of waste electrical electronic equipment (WEEE) with green processes one pending tasks; thus, in present review, advances solid–liquid liquid–liquid extraction processes, among most important for recovery metals from ores or WEEE, solvents such ...
