A number of manufacturers started commercial production of nickel—MH cells in 1991 (31—35). The initial products are "AA"-size, "Sub-C", and "C -size cells constmcted in a fashion similar to small sealed nickel —cadmium cells. Table 6 compares the Ovonics experimental cell and a similar sized nickel—cadmium cell. Ovonics also deUvered experimental electric vehicle cells, 22 A-h size, for testing. The charge—discharge of "AA" cells produced in Japan (Matsushita) are compared in Figure 22.

The situation is different for other examples—for example, the peptide hormone glucagon and a small peptide, metallothionein, which binds seven cadmium or zinc atoms. Here large discrepancies were found between the structures determined by x-ray diffraction and NMR methods. The differences in the case of glucagon can be attributed to genuine conformational variability under different experimental conditions, whereas the disagreement in the metallothionein case was later shown to be due to an incorrectly determined x-ray structure. A re-examination of the x-ray data of metallothionein gave a structure very similar to that determined by NMR. 

Rows 12-16 in Table 201 show that the acceleration by cadmium ion is not linear with concentration, becoming proportionally less as the concentration is increased. The last entry shows the magnitude of the experimental error in the acid-catalysed portion of the reaction for this result now indicates that cadmium ion has no effect on the acid-catalysed reaction. 

Generally, the experimental results on electrodeposition of CdS in acidic solutions of thiosulfate have implied that CdS growth does not involve underpotential deposition of the less noble element (Cd), as would be required by the theoretical treatments of compound semiconductor electrodeposition. Hence, a fundamental difference exists between CdS and the other two cadmium chalcogenides, CdSe and CdTe, for which the UPD model has been fairly successful. Besides, in the present case, colloidal sulfur is generated in the bulk of solution, giving rise to homogeneous precipitation of CdS in the vessel, so that it is quite difficult to obtain a film with an ordered structure. The same is true for the common chemical bath CdS deposition methods.

In a first part, experimental methods for studying formation, properties, structures and bonding in complex compounds of cadmium and mercury are briefly surveyed, usually with hints to reviews of the respective field and to examples of recent applications.

In this chapter, we characterize in situ vertical transfer process of LB films of cadmium octadecanoate and other amphiphiles by using a QCM as a dipping substrate. Experimental set-up is shown in Figure 1. A transfer amount of dry LB films (W, / ng), an incorporated amount of water during a lifting process (W2/ ng), and... 

The detachment experiments were carried out at the different surface tension of the water surface. The surface pressure was controlled in the range of 0-10 mN m-1 with ethyl tetradecanoate monolayer that was confirmed not to be transferred onto a substrate under the experimental conditions. The detachment amounts of cadmium octadecanoate LB films at various surface pressures are shown in Figure 19. At the high surface pressure (the low surface tension) the detached amount became negligibly small, which means the surface tension of water is the driving force of the detachment of LB films at the air-water interface. 

The reproductive systems of both males and females can be harmed by particular chemicals. In males certain chemicals cause the testes to atrophy and reduce or eliminate their capacity to produce sperm. Particularly striking in this regard is a now banned but once widely used pesticide called DBCP, residues of which persist in ground water supplies in a few regions of the country. Its pronounced impact on spermatogenesis is readily detectable in experimental animals and, unfortunately, has also been observed in some men once occupation-ally exposed to large amounts. The heavy metal cadmium is another substance effective at reducing sperm production.

When the D-value is experimentally found to be constant over a wide range of calcium and cadmium concentrations, the incorporation most likely proceeds by isomorphous substitution.

Cadmium sulfide is moderately toxic to experimental animals by aU routes of exposure. Toxicity in humans is low. It is, however, carcinogenic to humans.
