But darkfield conventional transmission electron microscopy can now reveal monatomic steps directly, as the micrograph in Fig. 12 shows (71). Using this kind of approach it should be possible to ascertain quantitatively the extent of the interaction between a catalyst and its underlying support. 

Selective chemical staining of the rubber phase of the samples using chlorosulphonic acid and osmium tetroxide, preparation of ultrathin sections (about 0.1 xm thick) in a cryoultramicro-tome, and investigation of the sections by conventional transmission electron microscopy (TEM). 

There are currently two variants of STEM, depending on whether it is specifically designed for scanning microscopy operation or adopted from conventional transmission electron microscopy work. Figure 3.1 shows a... 

Wash-coat separated from the cordierite monolith by scraping was examined directly by two electron microscopy techniques CTEM (Conventional Transmission Electron Microscopy) and STEM (Scanning Transmission Electron Microscopy).

As in the field of condensed matter sciences, polymer research has made extensive use of conventional transmission electron microscopy (CTEM) ever since its invention. Polymer research focuses on materials that mainly consist of carbon and other light elements. These materials are relatively weak electron scatterers and therefore give low mass thickness and phase contrast. Mass thickness contrast may be enhanced using an objective aperture, staining, and/or low... 

There are two main classes of electron micro.s-copy (EM) techniques. In the first class, the electron probe is a stationary beam incident along a fixed direction. This incident beam can be parallel [conventional transmission electron microscopy (CTEM), high-resolution transmission electron microscopy (HRTEM), high-voltage transmission... 

TEM has two basic modes, one is conventional transmission electron microscopy (CTEM or TEM for short) mode using a broad beam, another one is scanning TEM (STEM for short) using a focused electron probe (by focusing the electron beam into a narrow spot) scanning across TEM specimen in a raster.

Conventional transmission electron microscopy is much preferable since it makes it possible to image very small domains and to obtain the corresponding electron diffraction pattern [11].
