Bioassays with terrestrial and aquatic species as monitoring tools of hydrocarbon degradation [PDF]

open access: yes, 2016
In this study chemical analyses and ecotoxicity tests were applied for the assessment of a heavily hydrocarbon-contaminated soil prior and after the application of a remediation procedure that consisted in the stimulation of soil autochthonous ...

Photoconductivity of Polycyclic Aromatic Compounds [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1961
Abstract The voltage, light intensity, and temperature dependences for photocurrent in multi-ring compounds were studied as well as the photocurrent produced by the limited-area illumination. The photocurrent was found to be ohmic over the range of voltage employed.

Treatment of polycyclic armoatic hydrocarbone in agriculture

open access: yesمجلة بغداد للعلوم, 2005
Despite the multiple sources of polycyclic compounds in the agricultural environment, this study suggests that it is possible to adopt the events of plants and their associated microorganisms in the soil, such as mushrooms and bacteria in the ...

SigmaFormer: Augmenting transformer encoders with COSMO sigma profiles for pure component property prediction

open access: yesAIChE Journal, EarlyView.
Abstract Transformer‐based molecular models pretrained on SMILES strings demonstrate strong performance in property prediction. However, these model often lack explicit integration of molecular surface charge distributions that govern intermolecular interactions such as hydrogen bonding and polarity.

One-Pot Synthesis of Triazolobenzodiazepines Through Decarboxylative [3 + 2] Cycloaddition of Nonstabilized Azomethine Ylides and Cu-Free Click Reactions

open access: yesMolecules, 2019
A one-pot synthesis of triazolobenzodiazepine-containing polycyclic compounds is introduced. The reaction process involves a decarboxylative three-component [3 + 2] cycloaddition of nonstabilized azomethine ylides, N-propargylation, and intramolecular ...

Interactions between Zooplankton and Crude Oil: Toxic Effects and Bioaccumulation of Polycyclic Aromatic Hydrocarbons [PDF]

open access: yes, 2013
We conducted ship-, shore- and laboratory-based crude oil exposure experiments to investigate (1) the effects of crude oil (Louisiana light sweet oil) on survival and bioaccumulation of polycyclic aromatic hydrocarbons (PAHs) in mesozooplankton ...

Svjetlom do heteropolicikličkih spojeva; Reakcije supstituiranih furostilbena [PDF]

open access: yesKemija u Industriji, 2007
Synthetic organic photochemistry, the chemistry of excited states of a molecule, differs from the ground state chemistry and provides a simple pathway to complicated structures, heavily obtainable by a classic synthetic approach.

AhR-mediated activities of polycyclic aromatic compound (PAC) mixtures are predictable by the concept of concentration addition

open access: yesEnvironment International, 2014
Risk assessments of polycyclic aromatic hydrocarbons (PAHs) are complicated because these compounds exist in the environment as complex mixtures of hundreds of individual PAHs and other related polycyclic aromatic compounds (PACs).
