And surface topography

Noticing the fact that the formula for determining surface deformation takes the form of convolution, the fast Fourier transform (FFT) technique has been applied in recent years to the calculations of deformation [35,36]. The FFT-based approach would give exact results if the convolution functions, i.e., pressure and surface topography take periodic form. For the concentrated contact problems, however. 

The problems associated with the application of this (or any other) model have been discussed. Because of the form of the typical isotherm, which exhibits a broad plateau region, fitting of experimental results to the model requires that data be obtained over a very broad range of concentrations. This is often very difficult to accomplish in practice, especially when difference methods are used to determine the amount of polymer adsorbed. Evaluation of adsorption in real systems is further complicated by a lack of knowledge of the available solid surface area. The latter may be affected by particle size, shape and surface topography and by polymer bridging between particles.

Mechanism of Anisotropic Etching. The rich details as to anisotropic etch rates, nature of reactions, and surface topography indicate that a complex mechanism is involved in silicon etching in alkaline solutions. A coherent mechanistic model has to address three basic aspects (1) the physical cause of the difference in the removal rates of atoms from the surface of different crystal orientations, (2) the kinetic processes that actualize such physical cause, and (3) the surface condition that determines the global removal rate of the surface atoms. 

Most of the physics of lubrication is traditional mechanics and mechanical engineering. But there are also topics such as interfacial temperature, electrical resistance and capacitance of lubricant films, optics as applied to surface contact and surface topography, etc., as well as aspects which cannot be distinguished from physical chemistry. However, it is not with the formal classification of the interdisciplinary components that this book is concerned but rather with their mutual...

Processing equipment requires a source of SCF, which passes through an extractor unit to a restricted orifice positioned in a particle collection-precipitation vessel held at a lower temperature and pressure (often ambient) than the extractor unit. There are several primary factors found to influence the physical properties of particle size, shape, and surface topography of products. Those factors are...
