We have investigated the electronic structure of environmentally persistent free radicals
(EPFRs) formed on two different metal oxides: Cu (II) O and ZnO. Cu (II) O is known to be …

Environmentally persistent free radicals (EPFRs) are stable organic radicals and pollutants
in atmospheric and soil particles. Knowledge of EPFR formation on pristine, unsupported …

Previous studies indicated that Environmentally Persistent Free Radicals (EPFRs) are
formed in the post-flame, cool zone of combustion. They result from the chemisorption of gas …

Environmentally persistent free radicals (EPFRs) have significant environmental and public
health impacts. In this study, we demonstrate that EPFRs formed on ZnO nanoparticles …

The formation of environmentally persistent free radicals (EPFRs) is usually related to
transition-metal oxides in particulate matter (PM). However, recent studies suggest that …

Environmentally persistent free radicals (EPFRs) are a class of composite organic/metal
oxide pollutants that have recently been discovered to form from a wide variety of substituted …

Environmentally persistent free radicals (EPFRs) are a newly emerging class of pollutants
that are known to be formed on metal oxides (MOs). Recent experimental investigations …

Previous studies have indicated environmentally persistent free radicals (EPFRs) are formed
when hydroxyl-and chlorine-substituted aromatics chemisorbed on Cu (II) O and Fe (III) 2O3 …

The formation of environmentally persistent free radicals in combustion system was
investigated from chemisorptions of chlorine-and hydroxy-substituted benzenes on transition …

We have examined the formation of environmentally persistent free radicals (EPFRs) from
phenol over alumina and titania using both powder and single-crystal samples. Electron …
