Also Formula common features

A common feature of aU the waiting-time formulas we have had, from the simple (25) to the general (51), is the presence of the factor 1 — p in the denominator. This is an important observation. As utilization at a station increases from 90% of capacity to 99%, waiting times [and so also loads, by (49)] typically increase by a factor of 10. 

A series of new Fe /Ln° clusters was successfully isolated under analogous conditions used to synthesise 6 [40]. This new cluster type has a general formula of [Fe 5Ln 4(bis-C[4])2(p4-0)2(p3-0H)2(p4-N03)2(dmf)8(H20)6](0H)3 (14, Ln = Gd, Tb or Dy, Fig. 25.5e). The metallic skeleton is best described as a square of Ln ions doubly-capped on distal edges by [Fe° 2(bis-C[4])]" moieties (Fig. 25.6e). The fifth Fe ion caps one side of the square, with two p4-nitrates and a p4-oxygen bridging the central metal ions. The capped square of Ln cations is another common structural feature observed upon moving from H4C[4] (cluster 5, Fig. 25.3d) to bis-H4C[4], and is also found in one other series of bis-C... 

Another important class of polar aprotic systems that can be relevant for magnesium electrochemistry is that of ionic liquids (ILs). Figure 13.4 presents formulae of relevant ionic liquids. This figure also includes tabulated physical properties of commonly used ILs in electrochemistry. The main important features of ILs are the possibility to obtain highly ionically conducting solutions with wide electrochemical windows, low...
