In comparison with other microscopy techniques such as optical microscopy or scanning electron microscopy, SPM offers a number of advantages in terms of resolution and magnification. However, due to image acquisition by raster scanning, the measurement is slower and the maximum image size is generally smaller as well. Table 1 list some of the more common applications for SPMs. 

By comparison, the distance between the hght source and sample in ctMiventional optical microscopy is on the order of millimeters. Not unlike other visitmaiy ideas ahead of their time, the technical difficulties associated with Synge s idea were only recently overcome at IBM in the mid-1980s, which marked the rediscovery of the technique now referred to as near-field scanning optical microscopy (NSOM, Figure 7.2). ... 

An unusually extensive battery of experimental techniques was brought to bear on these comparisons of enantiomers with their racemic mixtures and of diastereomers with each other. A very sensitive Langmuir trough was constructed for the project, with temperature control from 15 to 40°C. In addition to the familiar force/area isotherms, which were used to compare all systems, measurements of surface potentials, surface shear viscosities, and dynamic suface tensions (for hysteresis only) were made on several systems with specially designed apparatus. Several microscopic techniques, epi-fluorescence optical microscopy, scanning tunneling microscopy, and electron microscopy, were applied to films of stearoylserine methyl ester, the most extensively investigated surfactant. 

This book describes the applications of important new NMR spectroscopic methods to a variety of useful materials and compares them with results from other techniques such as adsorption, differential scanning calorimetry, thermally stimulated depolarization cmrent, dielectric relaxation spectroscopy, infrared spectroscopy, optical microscopy, and small-angle and wide-angle x-ray scattering. The text explores the application of NMR spectroscopy to examine interfacial phenomena in objects of increasing complexity, beginning with immodified and modified silica materials. It then describes properties of various mixed oxides with comparisons to individual oxides and also describes carbon materials such as graphite and carbon nanotubes.
