Langmuir cells

Langmuir cells (Fig. 8 h) are very similar to Knudsen cells. Here the vaporization of a solid from its uncovered surface can be measured in a similar way by thermo-gravimetric methods.

The surface motion is of many scales, spanning from mm-waves to meso-scale eddies. In our discussion perhaps the range 10 1 to 103 meters is of interest. Surface slicks are only observed for relatively low and moderate winds. The surface motion during slick conditions may, however, be the result of earlier wind induced turbulence and Langmuir cells in the upper ocean layer. Small scale motion (of the order of 10 cm or less) is probably due to a convective motion in a shallow surface layer (Gemmerich and Hasse 1992). 

This analogy depends on identifying one of Langmuirs cells, which can hold two electrons, with the modern notion of an atomic orbital. 

A Langmuir-Hanes plot based on the Monod rate equation is presented in Figure 8.7. The Monod kinetic model can be used for microbial cell biocatalyst and is described as follows ... 

Langmuir films have been generated not only from phospholipids but also from tetraether lipids (Fig. 14b). Tetraether glycerophospho- and glycoUpids are typical for ar-chaea, where they may constitute the only polar lipids of the cell envelope [154,155]. Tetraether lipids are membrane-spanning lipids, a single monolayer has almost the same thickness as a phospholipid bilayer.

Gorter and Grendel in 1925 [527], drawing on the work of Langmuir, extracted lipids from RBC ghosts and formed monolayers. They discovered that the area of the monolayer was twice that of the calculated membrane surface of intact RBC, indicating the presence of a bilayer. This was the birth of the concept of a lipid bilayer as the fundamental structure of cell membranes (Fig. 7.1). 

All the work we describe in this chapter was carried out in UHV on the rutile Ti02(l 1 0)1 x 1 surface. Exposures to vapors and gases are given in Langmuirs (L) where 1 L = 1.333 x 10 s mbar s. Coverages of defects or molecules adsorbed at the surface will be given in monolayers (ML), where 1 ML corresponds to the density of primitive surface unit cells.

Mann, Thurgood, and coworkers—Langmuir-Hinshelwood kinetic model for methanol steam reforming and WGS over Cu/Zn. Mann et al.335 published a complex Langmuir-Hinshelwood model for CuO/ZnO catalysts based on what one would encounter for a methanol steam reformer (MSR) for fuel cell applications. The water-gas shift rate, containing all MSR terms, was determined to be ...
