Electron Paramagnetic Resonance
John A. Weil,James R. Bolton +1 more
TL;DR: In this paper, the authors measured the microwave power absorbed when the electrons transition to a higher energy state using the bridge circuit to quantify the absorption of photons from the electromagnetic field, which is known as the resonant frequency due to similarities the system shares with classical resonant systems.
Journal ArticleDOI
Quinoid redox cycling as a mechanism for sustained free radical generation by inhaled airborne particulate matter
TL;DR: It is hypothesized that semiquinone radicals in PM(2.5) undergo redox cycling, thereby reducing oxygen and generating reactive oxygen species while consuming tissue-reducing equivalents, such as NAD(P)H and ascorbate, which cause oxidative stress at sites of deposition and produce deleterious effects observed in the lung.

Emissions of organic air toxics from open burning: a comprehensive review
TL;DR: In this article, a detailed literature search was performed to collect and collate available data reporting emissions of organic air toxics from open burning sources, including accidental fires, agricultural burning of Crop Residue, agricultural plastic film, animal carcasses, Automobile Shredder Fluff Fires, Camp Fires, Car- Boat-Train (the vehicle not cargo) Fires, Construction Debris Fires, Copper Wire Reclamation, Crude Oil and Oil Spill Fires, Electronics Waste, Fiberglass, Fireworks, Grain Silo Fires, Household Waste, Land Clearing

Combustion Products of Plastics as Indicators for Refuse Burning in the Atmosphere
TL;DR: 1,3,5-Triphenylbenzene and tris(2,4-di-tert-butylphenyl)- phosphate were found in detectable amounts in atmospheric samples where plastics and refuse were burned in open fires, and thus it is proposed these two compounds as specific tracers for the open-burning of plastics.

The Radicals in Cigarette Tar: Their Nature and Suggested Physiological Implications
TL;DR: The paramagnetism of cigarette tar is found to be associated with at least four different types of species, which indicates that the principal paramagnetic species in tar is not an organic monoradical (doublet) species but instead is a donor-acceptor excimer with a paramagnetic excited state and a diamagnetic ground state.
