Identification and Toxicological Evaluation of Unsubstituted PAHs and Novel PAH Derivatives in Pavement Sealcoat Products

open access: yes, 2016
Pavement sealcoat products contain high concentrations of unsubstituted polycyclic aromatic hydrocarbons (PAHs), but the assessment of the potential toxicological impact is limited without the inclusion of PAH derivatives.

Analysis of polycyclic aromatic hydrocarbons (PAHs) and their adsorption characteristics on activated sludge during biological treatment of coking wastewater

open access: yes, 2016
Experiments were conducted to investigate the concentrations of PAHs and their adsorption characteristics by activated sludge in this study. Influence of sorption time, sludge concentration, and pH on PAHs adsorption was evaluated.

Synergistic Molecular Modulation of ππ Stacking for High‐Performance Pitch‐Derived Hard Carbon Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A synergistic molecular strategy is demonstrated to disrupt intrinsic ππ stacking in pitch, boosting 6‐fold sulfonation, yielding a hard carbon with 0.371 nm interlayer spacing and maximized closed pores, and achieving a high reversible capacity, remarkable rate capability (205.6 mAh g−1 at 2 A g−1) and cyclic stability.

The hydrogen coverage of interstellar PAHs [PDF]

open access: yes, 1986
The rate at which the CH bond in interstellar Polycyclic Aromatic Hydrocarbons (PAHs) rupture due to the absorption of a UV photon has been calculated. The results show that small PAHs (less than or equal to 25 carbon atoms) are expected to be partially ...

Carbon Nanopatch‐Decorated Defect‐Rich Regions for Stable Zinc Metal Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
To improve the stability of Zn anodes, a carbon‐nanopatch strategy based on candle‐flame pyrolysis is proposed. After rinsing, carbon nanoparticles are mainly retained in defect‐rich regions on the Zn surface, where they help alleviate local field intensification, improve interfacial uniformity, and mitigate parasitic reactions.

Biomarkers of lung congestion and injury in acute heart failure

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 781-789, April 2025.
Abstract Acute heart failure (AHF) classification and management are primarily based on lung congestion and/or hypoperfusion. The quantification of the vascular and tissue lung damage is not standard practice though biomarkers of lung injury may play a relevant role in this context.
