ANALYTICAL METHODS
This work uses a portable mass spectrometer (MS) for lab-based water quality monitoring of organic compounds, which are present in highly toxic nuclear waste ponds. This is due to a number of effects that such species have on storage of radioactive w

Uranium oxide catalysts supported upon gamma-Al2O3 and amorphous and mesoporous silica have been tested for CO/O-2 and NO/CO conversions. Pre-calcination is deleterious to catalysts on a mesoporous support due to extrusion of the active uranium phase

The conversion of alcohols, ethers, and carbonyl compounds using zeolite β, zeolite ZSM-5, and zeolite Y are compared and contrasted. The proton form of zeolite β is found to be as active as H-ZSM-5 for this reaction, whereas zeolite Y is much less
