Geiger Research Published in Nature Communications

July 17, 2017

A study by Professor Franz Geiger was published in Nature Communications. According to the study, the concentration of ultrafine particles less than 50 nanometers in diameter rose by one-third in the air of Sao Paulo, Brazil when higher ethanol prices induced drivers to switch from ethanol to gasoline. The paper was co-authored by Alberto Salvo, Joel Brito, and Paulo Artaxo. It is titled "Reduced ultrafine particle levels in Sao Paulo's atmosphere during shifts from gasoline to ethanol use."
