A review on polycyclic aromatic hydrocarbons: Source, environmental impact, effect on human health and remediation

, 2016
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants generated primarily during the incomplete combustion of organic materials (e.g. coal, oil, petrol, and wood).

Supramolecular aromaticity

Journal of Molecular Structure, 2014
We report experimental and theoretical evidences for supramolecular aromaticity as a new concept to be widely used in researches about molecular crystals. CSD survey regarding frequently encountered resonance-assisted H-bonds (RAHBs) in formic acid, formamide, formimidamide, formic acid-formamide, and formamide-formimidamide dimers shows that ...

Global modeling of secondary organic aerosol formation from aromatic hydrocarbons: high- vs low-yield pathways [PDF]

, 2007
Formation of SOA from the aromatic species toluene, xylene, and, for the first time, benzene, is added to a global chemical transport model. A simple mechanism is presented that accounts for competition between low and high-yield pathways of SOA ...

An Aromatic Inventory of the Local Volume [PDF]

, 2010
Using infrared photometry from the Spitzer Space Telescope, we perform the first inventory of aromatic feature emission (AFE, but also commonly referred to as PAH emission) for a statistically complete sample of star-forming galaxies in the local volume.

On the Aliphatic versus Aromatic Content of the Carriers of the "Unidentified" Infrared Emission Features

, 2016
Although it is generally accepted that the so-called "unidentified" infrared emission (UIE) features at 3.3, 6.2, 7.7, 8.6, and 11.3 micrometer are characteristic of the stretching and bending vibrations of aromatic hydrocarbon materials, the exact ...
