Oxidative stress induced by zero-valent iron nanoparticles and Fe(II) in human bronchial epithelial cells.
To identify the mechanism through which nanoparticulate zero-valent iron (nZVI; Fe0(s)) damages cells, a series of experiments were conducted in which nZVI in phosphate-buffered saline (PBS) wasExpand

Carbon-Centered Free Radicals in Particulate Matter Emissions from Wood and Coal Combustion
Electron paramagnetic resonance (EPR) spectroscopy was used to measure the free radicals in the particulate matter (PM) emissions from wood and coal combustion. The intensity of radicals in PMExpand

Bent Silica Fiber Evanescent Absorption Sensors for Near-Infrared Spectroscopy
Silica optical fibers have been modified to improve their sensitivity as evanescent wave sensors for liquids. A section of fiber is stripped of its cladding and bent or coiled, which significantlyExpand

Increased cytotoxicity of oxidized flame soot
Abstract Combustion–generated particles released into the atmosphere undergo reactions with oxidants, which can change the particles’ physiochemical characteristics. In this work, we compare theExpand

The influence of thiophene on the selective reduction of NO by NH3
The selective reduction of NO by NH3 addition has been studied in a lean-burning oil-fired laboratory combustion tunnel with pyridine and thiophene added to the fuel oil. Two distinct butExpand

Total Organic Carbon Content in Aqueous Samples Determined by Near-IR Spectroscopy
We describe the application of near-infrared spectroscopy with partial least-squares (PLS) multivariate calibration to determine the total organic carbon (TOC) content of aqueous organic samples. WeExpand

Direct identification of free-radical products ofO-atom reactions with olefins, using high-intensity molecular beams
Direct identification of the major and minor products produced by the reactions of O atoms with ethylene, propylene, 2-butene (cis and trans), and isobutene has been accomplished in experiments inExpand
