Estimates of the oxidation states of magmas are important to current investigations of the geo-chemical characteristics of their source regions and of evolved magmatic series created during differentiation. One means of achieving such estimates is to

The billions of tons of mineral dust released into the atmosphere each year provide an important surface for reaction with gas-phase pollutants. These reactions, which are often enhanced in the presence of light, can change both the gas-phase composi

Although organosulfates (ROSO3–) comprise a significant component of secondary organic aerosol (SOA) mass, their atmospheric formation mechanisms are not fully understood. Here, using methacrolein as a model organosulfate precursor, we present a ne
