The study of soil chemistry through quasi-steady-state models: II. Acidity of soil solution
Geochimica et Cosmochimica Acta, 1990Abstract The acidity of three hypothetical soil solutions was studied with a quasi-steady-state model. Processes were assigned to one of three time scales: fast (processes at equilibrium), slow (processes for which the kinetics are specified explicitly), or very slow (processes that have a negligible effect on the steady-state solution).

Data on deposition and streamwater chemistry, obtained for the upper catchment of the River Duddon in the 1970s and 1980s, are reviewed. These data, together with soil chemical data, are used to deduce key processes in the deposition-catchment interaction, the analysis being based on current concepts of acidification.

Abstract Many reduced-model methods have been developed to alleviate the computational expense of simulating chemically reacting flows with detailed kinetics. However, it is still impossible to determine exactly the loss in accuracy relative to the full model when reduced kinetic models are used for predicting quantities of interest (typically state ...

Thin Solid Films, 1999
Abstract Polarization-modulated Fourier-transform infrared reflection absorption spectroscopy has been applied to the characterization of thin films of AlN and Al oxynitride (‘AlON’) on NiAl(111) and to the observation of surface chemical processes under steady-state conditions in a static NH 3 ambient of up to 200 Torr.
