The One

The absorption and possible reaction paths during corrosion have been systematically identified at the molecular level by us-ing density functional theory calculations. The results show that the co-adsorbed water molecule has a two-fold impact on the corrosive kinetics process. The one is the solvation effect, where water molecule affects the various reactions through ion dipole interaction, without bond fracture and formation. Another is the H-transfer mediator, where the bond of co-adsorbed water molecule breaks and regenerates in order to transfer hydrogen atoms.

Excess Absorption

A general two-friction itinerant-oscillator model is given for molecular motion in dipolar fluids. The polarizability and relevant time-correlation functions are calculated by numerical methods. It is shown how the results of an earlier paper are obtained when the two frictions per unit inertia are equal. The model is compared with recent experimental measurements on hexanone-2 and acetonitrile obtained by using a new quasi-optical technique for frequencies intermediate between the MW and FIR spectral regions. This technique is described briefly; in particular, for a reasonable fitting of the theory to experiment the moment of inertia of the outer cage of molecules is always greater than that of the inner dipole in agreement with the original concept, namely a cage of dipoles surrounding a typical dipole. This is at variance with the earlier concept of the model where the friction on the encaged dipole is zero. There, for a good fit to experiment, the moment of inertia of the cage is always less than that of the dipole. This suggests that the two friction version should be used for such comparison. An analytical formula (analogous to the Rocard equation) for the polarizability derived earlier is shown to agree well with the result of numerical Fourier transformation of the response function. A distinct harmonic peak structure is noted in the FIR region of the spectrum when friction does not act on the inner dipole. The structure is damped out as this friction is increased. Thus only the first harmonic peak is significant when the frictions per unit inertia are approximately equal. Measurements in the frequency region (the intermediate region) lying between the microwave and the FIR for hexanone-2 in dilute solutions of cyclohexane are reported. These show a significant excess absorption over that predicted by the model in this region. It is suggested that the excess absorption arises from jumping of dipoles from well to well of the cosine potential of dipole-dipole interaction indicating that the effects of finite potential well depth must be incorporated in the model to explain the intermediate frequency absorption.

Permanent Form

An asymptotic theory of two-dimensional planetary solitary eddies is presented. Previous studies in one-and-a-half layer models have discovered special classes of radially symmetric structure which are associated with eddies of permanent form. We generalize these studies by including an active lower layer and by considering the effects of azimuthal structure. Accordingly, we stress two main results; namely, (i) permanent-form two-layer eddies with essentially arbitrary radial structure exist, provided that the eddy includes a weak imbedded dipolar asymmetry and an appropriate counter-rotating deep flow, and (ii) fluid trapped under an eddy in Taylor columns can significantly affect eddy properties if the trapped fluid possesses non-trivial potential vorticity.The structural permanency in our solutions arises from a balance between nonlinear steepening, driven by the continuity equation, and planetary dispersion. The structural asymmetries affect eddy propagation, either by dipole interaction within the layer (as occurs in modons) or by pressure forces acting between layers. The primary role of the deep counter-rotating flow is to balance the net upper-layer transport. The interesting layer-layer interaction, however, involves higher-order dynamics and is sensitive to the continuity of the potential-vorticity field. In general, these eddies trap fluid both in the upper thermocline and in the lower layer.The dominance of oceanic anticyclones over cyclones is relatively well known. A main conclusion of this study is that the class of long-lived anticyclones is considerably broader than previously realized. This may help explain the observed bias toward anticyclonic eddies. A second conclusion is that estimates of material transport by eddies may need to account for the movement of fluid outside the main bowl of the eddies.
