3D and 2D aromatic units behave like oil and water in the case of benzocarborane derivatives

Nature Communications, 2022
2D/2D fusion of aromatic halves leading to a global aromatic is found in many polycyclic aromatic hydrocarbons, whereas 2D/3D aromaticity is difficult to achieve. Here the authors report a computational chemistry investigation showing that 3D/2D aromatic

Extraction of Coal Liquefaction Residue with Aliphatic Hydrocarbon Solvents and the Separation and Characterization of Extracts by n-Heptane

Taiyuan Ligong Daxue xuebao, 2022
The effects of four aliphatic hydrocarbon extractants (n-hexane, cyclohexane, petroleum ether, and n-heptane) on the extraction rate and properties of extracts from coal liquefaction residue were investigated by Soxhlet extraction experiments.

Alteration and release of aliphatic compounds by the polychaete Nereis virens (Sars) experimentally fed with hydrocarbons [PDF]

, 2001
In the laboratory, marine worms were fed with a mixture of algae and several aliphatic hydrocarbons for 15 days. After ingestion by the worms, 34.9% of hydrocarbons are found in the faeces and only 3.1% accumulated in the gut.

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

Advanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Diversity‐Oriented Two‐Step Annulative π‐Extension Enables Access to Structurally Complex Nanographenes

Angewandte Chemie, EarlyView.
Pd‐catalyzed C–H arylation of polycyclic aromatic hydrocarbons (PAHs) with various aryltrimethylsilanes enables the preparation of structurally complicated arylated PAHs, which can be further transformed to nanographenes in a manner of two‐step annulative π‐extension (APEX) reaction.

MONITORING OF POLYCYCLIC AROMATIC HYDROCARBONS IN PRUNUS SPINOSA TREE COMPONENTS FROM CLUJ-NAPOCA AREA, ROMANIA

Agricultura, 2022
Polycyclic aromatic hydrocarbons (PAHs) occur as contaminants in different types of food mainly as a result of environmental pollution, food packaging and processing. The levels observed in food are determined by the source of the contamination.
