First direct detection of large polycyclic aromatic hydrocarbons on asteroid (162173) Ryugu samples: An interstellar heritage

Natural Sciences
Polycyclic aromatic hydrocarbons (PAHs) are considered major players in the physics and chemistry of star‐ and planet‐forming regions. The interstellar PAH hypothesis is based on our understanding of the origin of the aromatic infrared bands (AIBs), a ...

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

PharmVar GeneFocus: CYP1A2—Clinical Impact, Genetic Variation, and Updated Nomenclature

Clinical Pharmacology &Therapeutics, EarlyView.
The Pharmacogene Variation Consortium (PharmVar) provides nomenclature for the highly polymorphic human CYP1A2 gene. CYP1A2 plays a crucial role in the biotransformation of several commonly used drugs, including antipsychotics, antidepressants, anxiolytics, and methylxanthines.

Polycyclic aromatic hydrocarbons (PAHs) in sugarcane juice

Food Chemistry, 2009
Abstract Sugarcane juice is a common beverage in many Brazilian cities. At harvesting season most sugarcane plantation is burnt and this procedure has been shown as an important source of PAHs emission. In the present study 80 samples of sugarcane juice collected from two Brazilian cities, in two different periods, were analysed for the presence of ...

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

ENERGY &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.

Investigation and Evaluation of Wax Deposition Treatment Methods in Large Natural Gas Plants

Energy Science &Engineering, EarlyView.
Problem: Wax blockage (Biphenyl, PAHs) in low‐temperature units crippled plant capacity. Solution: A novel Circulating Light Hydrocarbon Injection technology. Mechanism: Light hydrocarbons disrupt wax crystals via “like dissolves like” and are continuously recovered. Outcome: 1. Throughput dropped from 10 MMscmd to 3 MMscmd 2.
