High Resolution Fourier Transform Infrared Spectroscopy Studies of Multidimensional H Transfer in Tropolone/Tropolonoid Molecules-a Bridge to the Behavior in Biological Systems

Lead Institution
Texas Technical University
Principal Investigator
Richard Redington
Project type
Large-Scale EMSL Research
In the year 2000 high resolution infrared spectroscopy experiments conducted in EMSL at PNNL were initiated on the nonrigid gaseous tropolone molecule (2-hydroxy-2,4,6-cycloheptatrien-1-one). On the…

Fabrication of a Carbon Nanotube Thermionic Cathode

Gregory Szulczewski
Project type
Large-Scale EMSL Research
Hydrogenation of 1-nitro-1-cyclohexene on an Au/TiO2 model catalyst Titanium dioxide is a well-known material for metal-supported catalysis and photocatalysis. In particular, the use of Au…

Hygroscopic Properties of Aerosol Organics

Lead Institution
Desert Research Institute
Principal Investigator
Douglas Lowenthal
Project type
Large-Scale EMSL Research
While organics constitute a large fraction of ambient aerosol mass, their role and effect on particle hygroscopic growth and cloud nucleation remains unclear. Organics are most often present in…

Desiccation of Porous Media to Limit Contaminant Migration

Lead Institution
Auburn University
Principal Investigator
Jacob Dane
Project type
Large-Scale EMSL Research
The primary attribute of soil desiccation is the removal of excess moisture from the subsurface, thereby reducing potential downward migration of water and contaminant solutes within the vadose zone…
