Aryl radical addition–dehydrocyclization drives rapid polycyclic aromatic hydrocarbon growth
Nature CommunicationsPolycyclic aromatic hydrocarbons are ubiquitous in space, yet astrochemical models fail to reproduce their observed abundances because known growth mechanisms are far too slow. Here, we report a plausible pathway for rapid polycyclic aromatic hydrocarbon

Impact of dry weather discharges on annual pollution from a separate storm sewer in Toulouse, France [PDF]
, 2013 The city of Toulouse with its separate sewer system is ideal for studying stormwater. However, during dry weather, the storm sewer also discharges water into the environment, and it is the impact of these discharges on annual pollution from storm sewer ...

Carbon and Hydrogen, EarlyView.By tuning the initial mixing temperature from 0°C to 80°C, the crystal size of SAPO‐34 can be adjusted from micro to nanoscale, reflecting a shift from classical single‐crystal growth at low temperatures to non‐classical polycrystalline aggregation at high temperatures.

Carbon Energy, EarlyView.This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

A Comparison of Polycyclic Aromatic Hydrocarbon Mobilization from Environmental Matrices [PDF]
A method has been developed to analyse PAHs in solid environmental matrices using an in-situ PFE-GC-MS method. The method involves the use of 2 g of alumina as the in-situ clean-up sorbent, in order to remove interferences and impurities in the soils ...

Chemistry – A European Journal, EarlyView.A one‐shot Pd(II)‐catalyzed C─H activation strategy enables the rapid conversion of simple linear propiolamides into structurally diverse mono‐, di‐, and tri‐olefin‐bridged MPAEs. This cascade process orchestrates up to six sequential C–H activations in a single operation, providing streamlined access to highly conjugated architectures.
