The synthesis and characterization of 15, 25, 50, and 70 nm thin iron films having chemical impurities below the detection limit of various analytical techniques even though they are prepared from low-grade iron sources is reported. Synthesis and Characterization of Chemically Pure Nanometer-Thin Zero-Valent Iron Films and Their Surfaces Danielle Faurie-Wisniewski and Franz M. Geiger J. Phys. Read More…

New collaborative work by the Martin, Thomson, and Geiger groups reports that half of the particle phase material produced from isoprene photooxidation via the HO2 pathway is accounted for by uptake of epoxydiol isomers. Uptake of Epoxydiol Isomers Accounts for Half of the Particle-Phase Material Produced from Isoprene Photooxidation via the HO2 pathway Yingjun Liu, Read More…

Collaborative work between Geiger and Salvo on the cover of Nature Geoscience. In this article, the authors describe results from a detailed analysis of measured air pollutants showing that ozone concentrations rose, and nitric oxide and CO concentrations fell, when motorists in the subtropical megacity of Sao Paulo, Brazil, used predominantly ethanol as opposed to Read More…

New paper in J. Phys. Chem. on binary mixtures of organic solvents at graphene surfaces over sapphire. Collaborative work between Geiger group member Jennifer Achtyl and and colleagues at the Oak Ridge Fluid Interface Reactions, Structures and Transport (FIRST) Energy Frontier Research Center (EFRC) shows that the extent to which hexanol/cyclohexane mixtures interact with sapphire Read More…
