Dimeric aggregates

The causes of the variations seen in Figs. 29, 30, and 31 are likely to result from a number of factors including the number of gold(I) ions involved in specific aggregates (dimers, trimers, extended chains, etc.), the distance between the gold(I) ions within any particular aggregate, the relative orientation... 

Changes in the solubility, ultracentrifugal behavior, number of SH groups and electron microscopic profiles in non-freeze stored or frozen myosins of rabbit and trout, as observed by Buttkus (50,51), supported those of Connell (91 ). The rate of aggregation was the highest around the eutectic point (-11°C) of the myosin-KCl-water system. Side-to-side aggregated dimers of rabbit myosin were observed by electron microscopy, as illustrated previously by Slayter and Lowey (92). 

In forming post-2000 theories of solutions, it is important to know what fraction of the ions in a solution are associated to form dimers and ttimers and perhaps higher aggregates. Dimers are not charged and will interact with the surrounding ions as... 

The initiation of styrene polymerization by r-butyl lithium in benzene is an apparent exception. The rates were found to be proportional to the first power concentration of the lithium compound and independent of the monomer concentration which was varied from 0.1 to 10-3 M172). This strange behavior is illustrated by Fig. 26. The authors proposed that the dissociation of r-butyl lithium into smaller, active aggregates, dimers or monomers, is the rate determining step of this process. However, the rate of initiation of isoprene by r-butyllithium in benzene shows a more conventional behavior it increases with increasing concentration of the monomer, although again it is proportional to first power concentration of r-butyl lithium. 

For very small aggregates (dimers, trimers, etc.) the value of A(o is negligibly small, for large aggregation numbers Aco can have significant values, because the net area of free monomers... 

In Chapter 3 the adsorption isotherms where discussed for some surfactant systems showing the formation of small aggregates (dimers or trimers) within the adsorption layer. There are quite a number of surfactants, which can be described by this model perfectly, for example the homologous series of fatty acids or alcohols or the alkyl sulphates [81],... 

VI, V2 and V3 are allosteric enzymes, which form aggregates. With increasing ion strength or solvent concentration, or in lyophilization, they can clump together to form larger aggregates (dimers, trimers, and so on), which have been demonstrated by electrophoresis. Both this new enzyme and the known ones have not only trans-...
