The technique just described requires the porous medium to be sealed in a cell, so It cannot be used with pellets of irregular shape or granular material. For such materials an alternative technique Introduced by Eberly [64] is attractive. In Eberly s method the porous pellets or granules are packed into a tube through which the carrier gas flows steadily. A sharp pulse of tracer gas is then injected at the entry to the tube, and Its transit time through the tube and spreading at the exit are observed. A "chromatographic" system of this sort is very attractive to the experimenter,... 

Commercial versions of PR are available. Other contactless methods of electro-modulation are Electron-Beam Electro-reflectance (EBER) and Contacdess Electroreflectance (CER). In EBER the pump beam of Figure 2 is replaced by a modulated low-energy electron beam (- 200 eV) chopped at about 1 kHz. However, the sample and electron gun must be placed in an ultrahigh vacuum chamber. Contactless electroreflectance uses a capacitor-like arrangement. 

Modulation Spectroscopy has proven to be an important characterization method for semiconductors and semiconductor microstructures. The rich spectra contain a wealth of information about relevant materials, surfaces and interfrces, as well as device characteristics. In general, the apparatus is relatively simple, compact (except EBER), inexpensive (except EBER), and easy to use. One of the main advantages of Modulation Spectroscopy is its ability to perform relevant measurements at room...

It was mentioned earlier (Sec. 8.6) that for iodo-de-diazoniation no catalyst is necessary because the redox potential of the iodide ion (E° = 1.3 V) is sufficient for an electron transfer to the arenediazonium ion. The reaction was actually observed by Griess (1864 c). Four iodo-de-diazoniation procedures are described in Organic Syntheses. For the syntheses of iodobenzene and 4-iodophenol (Lucas and Kennedy, 1943, and Daines and Eberly, 1943, respectively) KI is used in equimolar quantity and in 1.2 molar excess. However, for 2-bromoiodobenzene and for 1,3,4-triiodo-5-nitrobenzene (replacement of a diazonio group in the 4-position by iodine), up to...

No drugs have been a more faithful companion to man throughout his history than salicylates, the forebears of aspirin. About 3,500 years ago the Ebers Papyrus recommended the application of a decoction of leaves of myrtle to the abdomen and back to get rid of rheumatic pains. Hippocrates championed the juices of the poplar tree and willow bark to treat fever and labor pains. These plants and trees are abimdant in compounds derived from salicylic acid, which gets its name from them (in Latin salix is a willow tree). For thousands of years on all continents they have helped to... 

In the earliest attempt to explain the reaction, Crowell (1929) used, in part, arguments based on the phase diagrams of the ZnO-PjOj-HjO system constructed by Eberly, Gross Crowell (1920). Later, Darvell (1984) advanced similar arguments using the phase diagrams of Salmon ... 

A number of innovations made in the 1920s and 1930s may be noted. Several attempts were made to reduce the dissolution of these cements in oral fluids and their adverse effect on the pulp by inclusion of oils and greases (Simon, 1929, 1932 Eberly, 1934). None have been considered beneficial (Palfenbarger, Schoonover Souder, 1938), a not surprising result because the inclusion of hydrophobic substances is bound to interfere in the setting of an aqueous cement. 

The silicophosphate cement originated with the dental silicate cement, for there is no doubt that early investigators experimented with mixtures of aluminosilicate glass and zinc oxide (Fletcher, 1878,1879 Eberly, 1928). It appears to have no particular advantages. As is often the case with hybrids, it can combine the worst features as well as the best of the parents, and often properties have intermediate values. Nevertheless, it continues to have a small but persistent usage arising from its one advantage over the...
