Chemistry of carbonaceous aerosols : studies of atmospheric processing and OH-initiated oxidation
… information essential for understanding their atmospheric evolution and environmental effects. Samples of particulate matter < 2.5 pm in diameter (PM2.5) were collected from the Mexico City Metropolitan Area (MCMA) for both bulk compositional analysis and single particle characterization. …

Impact of atmospheric cycling on the release of iron and manganese into seawater from Saharan soil particles
Atmospheric transported dust is a major source of iron, manganese and other nutrients to the ocean. During atmospheric transport, dust containing iron and manganese undergoes cloud processes that can increase the reactivity and solubility of iron and manganese species when they enter into seawater. …

Cavity ring down: Construction, validation and experiments measuring the optical extinction of pure clays and their mixtures with salts and carboxylic acids under a range of atmospherically relevant conditions
… optical properties of laboratory generated, atmospherically relevant aerosols over a range of conditions. The CRD provides an absolute and unbiased in situ measurement of total extinction and can reduce uncertainties associated with aerosols having unusual chemical and physical …

Processing parameters and kinetics of phosphate-based dechlorination for electrorefiner salt waste
Pyroprocessing generates a salt waste stream of fission products dissolved in alkali chloride salts. Iron phosphate (FePs) glasses have been identified as candidate materials due to the high waste loading, good chemical durability, and lower processing temperatures. Phosphate-based dechlorination …

Photochemistry of Polycyclic Aromatic Hydrocarbons with Environmentally Relevant Metals
… extraction (SPE), and electrospray ionization/atmospheric pressure chemical ionization mass spectroscopy (ESI/APCI-MS). HULIS production is based on comparison to SRFA and is observed in short chain PAH following a surface dependent path through naphthalene derivative intermediate structures. …
