Toxicities of Polycyclic Aromatic Hydrocarbons for Aquatic Animals

open access: yesInternational Journal of Environmental Research and Public Health, 2020
Polycyclic aromatic hydrocarbons (PAHs) are organic compounds that are widely distributed in the air, water, and soil. Recently, the amount of PAHs derived from fuels and from incomplete combustion processes is increasing. In the aquatic environment, oil

A review of epidemiological studies on neuropsychological effects of air pollution

open access: yesSwiss Medical Weekly, 2012
The aim of the present review is to provide an update of the epidemiological evidence of the effects of air pollution on neuropsychological development and impairment, as well as of the evidence on individual susceptibility to these effects. Animal

On the Origin of the 3.3 Micron Unidentified Infrared Emission Feature [PDF]

open access: yes, 2017
The 3.3 $\mu$m unidentified infrared emission feature is commonly attributed to C-H stretching band of aromatic molecules. Astronomical observations have shown that this feature is composed of two separate bands at 3.28 and 3.30 $\mu$m and the origin of ...

Individual and Combined Inhalational Sedative Effects in Mice of Low Molecular Weight Aromatic Compounds Found in Agarwood Aroma

open access: yesMolecules, 2021
Agarwood is known to have a sedative effect and the less studied volatile aromatic constituents it contains may have contribution to the activity. In this study, two Kyara grade (highest-grade agarwood in Japan) samples were extracted using headspace ...

Carbohydrate–Aromatic Interactions [PDF]

open access: yesAccounts of Chemical Research, 2012
The recognition of saccharides by proteins has far reaching implications in biology, technology, and drug design. Within the past two decades, researchers have directed considerable effort toward a detailed understanding of these processes. Early crystallographic studies revealed, not surprisingly, that hydrogen-bonding interactions are usually ...

Recovery and Utilization of Lignin Monomers as Part of the Biorefinery Approach

open access: yesEnergies, 2016
Lignin is a substantial component of lignocellulosic biomass but is under-utilized relative to the cellulose and hemicellulose components. Historically, lignin has been burned as a source of process heat, but this heat is usually in excess of the process

Hydrogenated polycyclic aromatic hydrocarbons: isomerism and aromaticity

open access: yesPhysical Chemistry Chemical Physics, 2020
A simple model based on adjacency matrices is introduced to study the stability of hydrogenated polycyclic aromatic hydrocarbons. Aromaticity governs their relative stability having the most stable isomers the higher number of non-hydrogenated rings.
