Compression costs are significant in large-scale adsorption systems for gases thus, pressure drop is critically important since it controls compression costs. A resonable gas velocity is 100 ft/min tSeider et al.. 20091. Pressure drop can be calculated from well-known correlations for flow in packed beds. For example, the pressure drop in a packed bed of rigid particle in laminar flow is tBird et al.. 1960 ...

In plasmon resonance gas sensors, which also usually operate at room temperatures, we have another situation. In these devices, in order to shift the operating point of the surface plasmon resonance toward an aqueous environment, a thin high-refractive index dielectric overlayer can be employed. The use of overlayers with higher refractive indexes allow for thinner overlayers and potentially better sensor sensitivity. Analysis of results obtained indicates that tantalum pentoxide, which has high refractive index (see Table 2.18) and good environmental stability, may be used for this purpose (Dostalek et al. 2001 Boozer 2003).

The rare imino and enol forms can lead to alternate base-pair combinations and thus cause mutations in replication. This type of mutation is called a tautomeric shift [2, 3]. Possible mismatches include iminoC-A, enolT-G, C-iminoA, and T-enolG. Tautomerization can occur in DNA by single or double proton transfer. In solution equilibrium, generally the keto form dominates, complicating efforts to study the properties of the individual forms. One approach to studying tautomeric properties is double-resonant gas-phase spectroscopy, as this technique offers isomeric selectivity. This chapter summarizes the results from such investigations.
