TL;DR: Phenanthrene, a 3-ring aromatic hydrocarbon, was used as a model substrate to analyze the effect of sorption on the bioavailability of polycyclic aromatic hydrocarbons (PAHs).

TL;DR: The successful synthesis of a threefold symmetric C78H36 molecule with 22 fused benzene rings is reported, which was characterized on an ultrathin insulating film with atomic resolution by scanning probe microscopy.
Abstract: The successful synthesis of a threefold symmetric C78H36 molecule with 22 fused benzene rings is reported. This clover-shaped nanographene was characterized on an ultrathin insulating film with atomic resolution by scanning probe microscopy.

TL;DR: This study investigates the cosolvency effect of ethanol on the aqueous solubility of mono- and polycyclic aromatic hydrocarbons, and presents a simple log-linear model to predict this effect under equilibrium conditions.

TL;DR: It is shown that typical 1,3-butadiene levels in engine exhaust are about 5 ppm at each of two engine conditions, and aromatic hydrocarbon levels show a dependence on engine operating conditions.
Abstract: A method for the quantitative analysis of individual hydrocarbons in the C1-C8 range emitted in engine exhaust gases is described. The procedure provides base-line or near base-line resolution of C4 components including 1,3-butadiene. With a run time of less than 50 min, the light aromatics (benzene, toluene, ethyl benzene, p- and m-xylene, and o-xylene) are resolved during the same analysis as aliphatic hydrocarbons in the C1-C8 range. It is shown that typical 1,3-butadiene levels in engine exhaust are about 5 ppm at each of two engine conditions. Aromatic hydrocarbon levels show a dependence on engine operating conditions, benzene being about 20 ppm at high speed and about 40 ppm at idle.
