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).

Characterizations of Size-segregated Ultrafine Particles in Diesel Exhaust
Size-segregated ultrafine particles (UFPs) in diesel exhaust were investigated to characterize carbonaceous substances, metals, and organic compounds originating from a medium-duty diesel engine dynamometer using the 13 driving mode.

Svjetlom do heteropolicikličkih spojeva; Reakcije supstituiranih furostilbena [PDF]
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.

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 ...

Chiral phosphoric acid catalyzed aminative dearomatization of α-naphthols/Michael addition sequence
Catalytic asymmetric dearomatization (CADA) reactions readily convert common aromatic compounds to diverse 3D chiral, polycyclic molecules. Here, the authors report an intermolecular asymmetric dearomatization of nucleophile-tethered α-naphthols ...
