Oxygen sensing changes

This variable has a physical sense of the motive power of isotopic exchange between oxygen molecules. If there were no isotopic exchange with catalyst oxygen the change of the fraction of the nonsymmetrical oxygen molecules (0 0 ) would be proportional to y. [Pg.290]

Simple heme-containing oxygen sensing molecules that respond to environmental changes are... [Pg.274]

According to this equation, for an amperometric oxygen-sensing electrode covered by a membrane of 100 pm thickness the steady-state current will be attained 38 s after changing the oxygen concentration (D = 3.9 10 cm Vs). Half of the steady-state value is reached at... [Pg.66]

Optical sensors based on UV-visible and fluorescence spectrophotometry and a visual color change in a material are other directions for mesoporous silicates application (Melde et al. 2008). Several examples of such sensors are presented in Table 8.2. Usually optical detection of gases in mesoporous silica-based sensors takes place through the use of an incorporated dye. In particular, oxygen sensing... [Pg.135]
