The olefin refrigerants are designed to take advantage of the OH radical chemistry in the local air environment and react quickly to form new chemical species that can be removed by the natural water cycle.
In the presence of chemical species, changes in signal amplitude per wavelength of the QCL give a characteristic absorption spectrum of each analyte and therefore a definitive fingerprint for molecular identification.
Further, large differences in the concentration and time scale of various chemical species involved in the chemical reaction as well as stiffness problems in calculations lead to numerous issues in applying simple combustion simulations.
To observe the boron accumulation within the oxide layers, the depth profile and chemical species of the oxide layers were analyzed by XPS analysis.
Given the deposition reactor geometry, chemical species and growth condition parameters, CyberEpi predicts the film growth rate and thickness uniformity based on detailed chemical kinetics and mass/heat transfer models.
Topics discussed include plasmonic imaging of electrochemical impedance; light-addressable potentiometric sensors for quantitative spatial imaging of chemical species; and the role of antibody mimetics in bioanalysis.
The first one accounts for local flow conditions but cannot include turbulence-chemistry interaction, the second one solves reaction-diffusion equations in the mixture fraction (Z) space having a limited number of nodes and then computes the chemical composition in each cell by presuming a [ss]-PDF distribution for the chemical species which is function of Z and its variance Z" (2).
But the details of the mechanism involve a large number of chemical species c (microscopic point of view), which are difficult to measure in a few steps.
