Associate formation

The authors considered three mechanisms, including (a) a regenerative (redox) mechanism like that of Weibel,359 (b) the associative (formate) mechanism of Shido and Iwasawa360,361 that has some aspects in common with the formate mechanism of Grenoble et al.229 and (c) a CO decomposition mechanism by Yao,345 which was deemed unlikely as CO generally adsorbed on the metal, and does not decompose. 

The decrease in the ammonia concentration at higher temperatures, above 350 °C, and the associated formation of N2 and H2 in a 1 3 ratio, on the other hand, are related to the decomposition of ammonia ...

The deviations from ideal behavior can be calculated for all thermodynamic and transport functions of mixtures of molten salts, and these reflect the phenomena which take place at mixing ion associations, formation of complex ions, etc.

Figure 56 uses the example of associate formation between the ionic defect O and the electronic defect h to emphasize that the strict treatment requires the solution of coupled diffusion-reaction relationships, describing the general (electro-)chemical reaction scheme with individual diffusion or rate constants as parameters (cf. Section VI. 2). Source terms (q) must be taken into account in the relevant continuity equations, e.g., for defect B that can be created by... 

The empty coordination sites on A1 and Zn are reversibly filled by electron pairs from alkoxide groups with intra- or intermolecular associate formation. The degree of association depends on the solvent, the type of metal M +, and the OR group in [(R0)4Al202M +] in benzene, n varies from 1 to 8. We assume that the monomers are inserted, with simultaneous ring opening, into the... 

The aggregates are polymerization inactive their formation is accompanied by a corresponding decrease in the polymerization rate [96], Aggregate formation is not limited to siloxane monomers and polymers. Independently, and in the same year, associate formation during anionic styrene polymerization was described by Worsfold and Bywater...

From an evolutionary perspective, the human cognitive architecture is far more likely to resemble a confederation of hundreds or thousands of functionally dedicated computers, dedicated to solving problems endemic to the Pleistocene, than it is to resemble a single general-purpose computer equipped with a small number of general purpose procedures such as association formation, categorization, or production-rule formation.
