Role of Kekul\'e and Non-Kekul\'e Structures in the Radical Character of Alternant Polycyclic Aromatic Hydrocarbons: A TAO-DFT Study

, 2016
We investigate the role of Kekule and non-Kekule structures in the radical character of alternant polycyclic aromatic hydrocarbons (PAHs) using thermally-assisted-occupation density functional theory (TAO-DFT), an efficient electronic structure method ...

Polycyclic Aromatic Hydrocarbons in Corn Grains

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Food Science and Technology, 2019
Contamination of crop plants with organic pollutants raises a growing interest in recent years; among the investigated pollutants, polycyclic aromatic hydrocarbons (PAHs) are of special concern because some of them are toxic and carcinogenic.

Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

Effect of Binder on Physical Properties of Extruded Activated Carbon and Its Application to Levofloxacin Adsorption

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Bamboo charcoal–based extruded activated carbons were prepared via molding, pre‐oxidation, carbonization, and steam activation, with coal tar, phenolic resin, and their mixtures employed as binders based on practical availability and technical feasibility. This study focused on the regulatory effects of binders on the mechanical properties and

Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...

Endogenous melatonin partial metabolic clearance as a potential endogenous marker of CYP1A2 activity

British Journal of Clinical Pharmacology, EarlyView.
Aims Cytochrome P450 1A2 (CYP1A2) exhibits substantial interindividual variability, necessitating appropriate phenotyping strategies for personalized pharmacotherapy. This study evaluated endogenous melatonin partial metabolic clearance (CLm(MEL)), calculated from urinary 6‐hydroxymelatonin (6‐O‐MEL) excretion and plasma melatonin (MEL) exposure, as a ...
