Water critical enhancements

BiCl3 is, however, little conducting in the liquid phase, and it resembles nonionic rather than ionic fluids. This may warn that specific interactions may destroy the peculiar effects of ionic criticality. Likewise, water (Tc = 647 K) shows Ising behavior [61]. At the critical point, autoprotolysis of water is enhanced by three orders of magnitude relative to ambient conditions [62]. 

The enhanced water solubihty, on the other hand, is caused by the existence of inverse micelles. The maximum size of these to allow maximum water solubilization depends critically on the alcohol/soap ratio in Figure lb maximum water solubility is obtained at a weight ratio of 5 2. 

The equation is given in dimensionless form with p = p/p and p = 317.763 kg m Values for the coefficients Hfj are listed in Table 14.15. The critical enhancement of the viscosity of steam occurs in a r on which covers approximately 1% in absolute temperature and 30% in density relative to the critical temperature and critical density, as shown in Figure 14.21. Inside this critical r on, the equations given above are used to rq>resent the background viscosity. In the case of water substance, it has been the practice to consider the relative critical enhancement, or viscosity ratio, rather than the absolute enhancement. The asymptotic behavior of the viscosity is written (Chapter 6) in terms of the correlation length f, which characterizes the spatial... 

Cyanoacrylate adhesives cure by anionic polymerization. This reaction is catalyzed by weak bases (such as water), so the adhesives are generally stabilized by the inclusion of a weak acid in the formulation. While adhesion of cyanoacrylates to bare metals and many polymers is excellent, bonding to polyolefins requires a surface modifying primer. Solutions of chlorinated polyolefin oligomers, fran-sition metal complexes, and organic bases such as tertiary amines can greatly enhance cyanoacrylate adhesion to these surfaces [72]. The solvent is a critical component of these primers, as solvent swelling of the surface facilitates inter-... 

The ORAC assay proposed by Ou and others (2001) is limited to hydrophilic antioxidants because of the aqueous environment of the assay. However, lipophilic antioxidants play a critical role in biological defense systems. Huang and others (2002) expanded the assay to the lipidic fraction by introducing a randomly methylated 13-cyclodextrin (RMCD) as a water-solubility enhancer for lipophilic antioxidants. Various kinds of foods, including fruit juices and drinks, fruits, vegetables, nuts, and dried fruits, have been evaluated with this method (Zhou and Yu 2006 Wu and others 2004 Kevers and others 2007 Wang and Ballington 2007 Almeida and others 2008 Mullen and others 2007).
