Microscopic observations were done on a Phillips High Resolution Scanning Electron Microscope. To reveal solid material inside the microcolumn, a freeze-fracture technique was used after samples were washed with methanol and dried under normal conditions.

The correlation coefficient is calculated by the technique of dipole or needle throwing. Consider a mixture of carbon black in PE with C average carbon black concentration. We fracture one peUet, and we take a photograph of the surface with the aid of a high resolution scanning electron microscope. We take a needle of length r and drop it onto the photograph. Four events can take place (1) both ends could land in carbon black particles with probability Pn (2) both ends could land in the PE matrix with probability P22, (3) the first end lands in carbon black and the second in PE with probability Pu, and (4) the opposite of the previous event with probability P2i- Nadav and Tadmor (1973) calculated the correlation coefficient as...

A CL system attached to a scanning electron microscope (SEM) provides a powerful means for the uniformity studies of luminescent materials with the spatial resolution of less than 1 pm. 

Run-of-the-mill instruments can achieve a resolution of 5-10 nm, while the best reach 1 nm. The remarkable depth of focus derives from the fact that a very small numerical aperture is used, and yet this feature does not spoil the resolution, which is not limited by dilfraction as it is in an optical microscope but rather by various forms of aberration. Scanning electron microscopes can undertake compositional analysis (but with much less accuracy than the instruments treated in the next section) and there is also a way of arranging image formation that allows atomic-number contrast, so that elements of different atomic number show up in various degrees of brightness on the image of a polished surface. 

Electron probe microanalysis functions by direct examination of the primary X-rays produced when the specimen is used as a target for an electron beam. Focused electron beams allow a spot analysis of a 1 pm3 section of the specimen. One current development employs the electron beam within a scanning electron microscope to provide both a visual picture of the surface of the sample and an elemental analysis of the section being viewed. Spectra obtained from primary X-rays always have the characteristic emission peaks superimposed on a continuum of background radiation (Figure 8.32). This feature limits the precision, sensitivity and resolution of electron probe microanalysis.
