Interface thinning

This volume contains 50 articles describing analytical techniques for the characterization of solid materials, with emphasis on surfaces, interfaces, thin films, and microanalytical approaches. It is part of the Materials Characterization Series, copublished by Butterworth-Heinemann and Manning. This volume can serve as a stand-alone reference as well as a companion to the other volumes in the Series which deal with individual materials classes. Though authored by professional characterization experts the articles are written to be easily accessible to the materials user, the process engineer, the manager, the student—in short to all those who are not (and probably don t intend to be) experts but who need to understand the potential applications of the techniques to materials problems. Too often, technique descriptions are written for the technique specialist.

Often the production of new materials such as composite materials heavily involves processes at interfaces. Thin films on surfaces are often dominated by surface effects. Examples are latex-films, coatings, and paints. The flow behavior of powders and granular media is determined by surface forces. In tribology, wear is reduced by lubrication which again is a surface phenomenon.

The tracing of the oxygen species is usually performed by oxidation first in 16C>2 and then 18C>2 enriched gas in the gas/solid interface. Thin ( 20 A) oxide film growths on single crystal metals at moderate temperatures can be studied by oxygen isotope labeling combined with high-resolution microscopy. In the case of liquid/solid and electrochemical interfaces there is another complication that arises from the existence of an electric field and the presence of an electrolyte solution with adsorbable anions and solvents. 

As resistive heating elements of this electrothermic interface thin film platinum resistors and surface mount technology (SMT) resistors are used (Richter et al. 2003, 2009a). The hydrogel components can be heated and cooled also by Peltier elements (Yu et al. 2003b Luo et al. 2003a).

The problems to be solved in interfacing thin-layer chromatography to mass spectrometry (TLC-MS) are largely different to those experienced in LC-MS and other column separation techniques [95-99]. At the completion of the separation the chromatogram is fixed in time and space with the major portion of the mobile phase eliminated by evaporation. The thin-layer plate can be considered as a storage device effectively de-...

The film between the interfaces thins due to the action of the external force, For small Reynolds number the external force is balanced by the sum of the hydrodynamic drag force and the intermolecular forces - it is the so-called steady-state approach. In the lubrication approximation from Eq. (17) it follows that ...

Coatings have been historically used by scientists to improve the properties and biological responses of the material-host interface. Thin films in particular are becoming more widely used and researched as an alternative to traditional sprayed coatings because they have been shown to have a more uniform structure and therefore greater stability in vivo.

There is one problem that makes homogeneous chemical reactions especially troublesome. Most often, a mechanism to be simulated involves species generated at the interface, that then undergo chemical reaction in the solution. This leads to concentration profiles for these species that are confined to a thin layer near the interface—thin, that is, compared with the diffusion layer (see Sect. 2.4.1.1, the Nernst diffusion layer). This is called the reaction layer (see [1, 6, 8]). Simulation parameters are usually chosen so as to resolve the space within the diffusion layer and, if a given profile is much thinner than that, the resolution of the sample point spacing might not be sufficient. The thickness of the reaction layer depends on...

The topic of magnetic properties of surfaces, thin films, and thin film systems (such as multilayers and superlattices) is of tremendous scientific and economic importance, not only for well-known data storage devices but also for future electronics, which may utilize the electrons spin in addition to their charge. Surfaces, interfaces, thin films, and nanostractures often display magnetic properties fundamentally different from the properties of bulk crystals, which are thus important to understand principles of magnetism. Recent experiments probed local magnetic moments (and their temperature dependencies) of films and their sur-faces/interfaces, small clusters, as well as nanowires, nanodots, and single atoms deposited on solid surfaces.
