Scanning electron microscopy-X-ray

Air-dry samples have been studied using the methods of scanning electron microscopy, X-ray microanalysis, thermal analysis and X-ray diffraction. The latter two methods are crucial for conclusions regarding thermal pre-treatment of samples to be exploited in power sources.

The use of photoresists to cover most of the metal surface and isolate individual pits has made possible detailed analysis of these entities, varying in radius from around 0.1 to 5 pm. The methods of examination include Auger spectroscopy, scanning electron microscopy, X-ray dispersive analysis, and atomic force microscopy (Ke and Alkyre, 1995). 

A final example of the role of additives is that of Larkins and Nordin.25 L12CO3 when added to MgO catalysts increases the selectivity to C2 hydrocarbons in oxidative coupling reactions of methane as has been found by others. Catalytic, scanning electron microscopy, X-ray powder diffraction, temperature programmed reactions and electron microprobe studies have been used to show that additives of both Zn and Mn can enhance selectivity to C2 hydrocarbons in these systems. 

The content of acid-soluble iron in paper is determined by TAPPI standard T434 (iron combined in clay and other complex compounds is presumed to be nonreactive). The presence of iron can be shown by the color produced upon wetting the paper briefly with warm 6N hydrochloric acid and then adding a solution of potassium ferrocyanide or thiocyanate localized specks of iron or rust are indicated by the more intense color formation. Complete analysis of paper for metallic elements has been accomplished by chemical procedures, emission spec-trography, scanning electron microscopy/x-ray, and neutron activation.

Nevertheless, despite these limitations, it will be evident from the succeeding chapters that great advances have already been made even though most of the research spans only a few decades. Modern techniques and instrumentation such as satellite imagery, scanning electron microscopy. X-ray analysis, electron and ion probes and computer assisted analysis are providing...

In the 1980s, the successful synthesis of elastomeric polyamides 120 of high molecular weight (d/n =10,000-18,000) was reported from the polycondensation of l,l -bis(/ -aminoethyl)ferrocene with diacid chlorides (Scheme 13). Also, polyureas 121 were prepared from the same ferrocene monomer and diisocyanates, and polyesters and polyurethanes were prepared from l,l -bis(/ -hydroxyethyl)ferrocene. However, the latter materials had much lower molecular weights and were characterized only by scanning electron microscopy. X-ray, and IR analyses. The introduction of ferrocenes in which the functional groups are separated from the cyclopentadienyl ring by at least two methylene units was crucial in order to reduce steric effects and to avoid the instability found previously in polymers of a-functionalized ferrocene due to the a-ferrocenyl carbonium ion stability.

Immediately after the interaction, debris was collected. The debris consisted of fine particulate suspended in the water and larger debris particles on the bottom of the chamber. The debris was subjected to a variety of analytical schemes that included scanning electron microscopy, x-ray diffraction, and photographic microscopy.

At the oil/water interface, however, we observed the formation of coherent, ultra-thin calcium carbonate films. These extended, two-dimensional crystalline stmctures were characterized by scanning electron microscopy. X-ray diffraction, and other techniques like interfacial-shear-rheology.
