A low pressure reactor (Knudsen cell) coupled to molecular beam modulated mass spectrometry was used to study the heterogeneous kinetics of the following three systems: (1) NO2 on amorphous carbon, (2) H2O vapor on ice and (3) gaseous HCl on ice. The first ...
In view of the uncertainty of the origin of the secular increase of N2O, we studied heterogeneous processes that contribute to formation of N2O in an environment that comes as close as possible to exhaust conditions contg. NO and SO2, among other constitue ...
Systematic errors due to the neglect of water and/or ethanol partition between liq. and gaseous phases are discussed for bioreactors equipped with or without a condenser. Both water vapor and ethanol vapor are present in the off-gas leaving the condenser. ...
The photothermal laser induced CVD of Cu from its hexafluoroacetylacetonate trimethylvinylsilane deriv. was studied as a function of added H2O vapor pressure. The height, width, elec. cond., and chem. compn. of the deposited Cu lines are measured. Under an ...
The conditional sampling formulation typically used in eddy accumulation flux measurements was tested at two sites using velocity, temperature, and specific humidity time series measurements. The first site was at Owen's Lake in southern California, and th ...
The low pressure chem. vapor deposition (LPCVD) of Cu from its bis-hexafluoroacetylacetonate was studied on oxidized Si substrates partially covered with a Pt seeding layer. With a known concn. of water vapor in the gas mixt., almost equal Cu film growth r ...
The selectivity of Cu deposition from bis(hexafluoroacetylacetonato)Cu(II) on SiO2 patterned with a Pt seeding layer was studied as a function of the reagent gas mixt. On Pt, the Cu film growth rate increases with the amt. of H2O vapor in the gas flow, and ...
A simple model based on the Monin-Obukhov surface layer similarity theory of heat and momentum transport can be used to predict the latent heat flux for a variety of atmospheric and soil moisture conditions. Experiments were carried out on the Campbell Tra ...
Low pressure CVD of Cu from its bis-hexafluoroacetylacetonate was studied on oxidized Si substrates locally seeded with a 2.5 .ANG. Pt prenucleation film. ...
Cavitation tests using models are essential to determine the full-scale machine cavitation behaviour. As erosion prediction is still very empirical, in practice a "safe" machine shows no visible cavitation on a model at sigma plant. However, this way of de ...
