Crystallization of ECSCs was isothermally carried out under high pressure using a piston cylinder high pressure cell with diamond window (PCDW) originally made by us. The formation of isolated ECSCs was confirmed by means of transmission electron microscopy (TEM). 

III. Transmission electron microscopy of radish seeds Transmission electron microscopy (TEM) of radish seeds was done as listed below For TEM preparations, the specimens after fixation and dehydration, were embedded in Epon 812 resin (Luft, 1961). Thick sections (ca. 1mm each) were stained with 0.1% toluidine blue and observed with a Zeiss light photomicroscope. Thin sections, obtained with a diamond knife on a Supernova microtome, were sequentially stained at room temperature with 2% uranyle acetate (aqueous) for 5 min and by lead citrate for 10 min (Reynolds, 1963). Ultrastructural studies were made using a Philips CM12 transmission electrone microscope (TEM) operated at 80 KV.

TEM (Transmission Electron Microscopy) analysis. This analysis was done on a Philips 420T microscope (120kV, maximum resolution 5A) equipped with an EDAX PV9900 EDS. The catalysts were ground to a powder, embedded in epoxy resin and then microtomed with a diamond l fe to obtain sections about 300A thick. Images were taken at 100 kV. Diameters of about 100 isometric-shaped Pt crystallites were measured for each sample. 

Microtomy refers to sectioning materials with a knife. It is a common technique in biological specimen preparation. It is also used to prepare soft materials such as polymers and soft metals. Tool steel, tungsten carbide, glass and diamond are used as knife materials. A similar technique, ultramicrotomy, is widely used for the preparation of biological and polymer specimens in transmission electron microscopy. This topic is discussed in Chapter 3. 

Thin sections for transmission electron microscopy were dry cut on a Reichert Ultracut ultramicrotome with a FC4D cryostatic unit temperatures were -100°C for the specimen and -80°C for the diamond knife. Sections stained with RuO vapor as well as unstained sections were viewed by means of a Zeiss EMIO electron microscope.

Field emission scanning electron microscopy (FESEM), glancing incidence x-ray diffraction (GIXRD), transmission electron microscopy (TEM), micro Raman scattering, Fourier transform inftaied (FTIR) spectrometry, Rutherford back scattering (RBS) studies and electron probe micro analysis (EPMA) have been carried out to obtain micro-structural and compositional properties of the diamond/p-SiC nanocomposite films. Atomic force microscopy (AFM) and indentation studies have been carried out to obtain film properties on the tribological and mechanical front. 

The degree of nanotube dispersion in polymer matrix was studied with transmission electron microscopy (LE0912 AB OMEGA, Germany). Microscopic sections with 70-100 nm width prepared with ultramicrotome Reichert-Jung Ultracut with diamond cutter at -80°C. Microscopic analysis was made with accelerating potential of about 100 kV without chemical sample staining. 

The octahedral pressure cells containing the samples were recovered from the multi-anvil experiment and either broken or cut in half, using a diamond wiresaw. In the latter case, the j -sialon samples were also halved in the axial direction. The specimens were then characterized with optical and scanning electron microscopy (SEM), transmission electron microscopy (TEM), electron probe microanalysis (EPMA), powder X-ray diffractometry (XRD), and microhardness testing using the Vickers method.
