According to these consideration the diamino-substituted phosphenium (an alternative suggestion for its nomenclature is phosphanylium) cation, 5, and the phosphanetriylammonium (iminophosphenium) cation, 6, possess the largest intrinsic (gas phase) stabihties. Since in the X-ray structures the molecules are to a first-order isolated, this theoretical stability scale determined for the gas phase should also mimic the various trends of the stabilities of the cations and their chelation behaviour. The methylenephosphenium, 7, and the PjH cations, 8, suffer from poor stabihties. On the other hand the phosphirenium cation, 11, is considered to be fairly well stabilized. It is due to n-electron delocalisation of the positive charge in the phosphirenium cation. Intermediate cases in stabihty are the PO+ (9) and PS+ cations (10). Of further interest are the frontier orbital considerations, as shown in Fig. 2. 

Figure 7.5 shows phase stabihty relations in the binary system NaAlSijOg-CaAl2Si20g (albite-anorthite), based on the experiments of Bowen (1913), Greig and Barth (1938), and Osborn (1942).

The titaniuin oxides are of considerable technological interest, so different theoretical studies of electronic and atomic structure and properties have been performed both for Ti02 [100,323,596,597] and Ti20s [598,599] crystals. We are not aware of the existence of the electronic-structure calculations of TiO. The available publications focus attention primarily on description of the band structure and phase stabihty of titanium oxides and restrict the discussion of the nature of chemical bonding in these compounds to an analysis of Mulhken atomic charges and overlap populations. 

Copolymers are becoming increasingly important for high performance and new materials with specific mechanical, optical, and electrical properties. The bivariate composition and mass distribution controls many aspects of the materials behavior, such as tensile strength, processability, surface, phase stabihty, and so on. Nonetheless, determining the bivariate distribution can be time consuming and costly, and usually requires the use of complementary techniques, such as thermal field-flow fractionation [8], temperature rising elution fractionation (TREE) [9], Fourier transform infrared (FTIR) spectroscopy [10], and other methods [11] for...

There have been numerous studies with the object of gaining an understanding of the factors that influence the stability, stoichiometry, and H site occupation in hydride phases. Stability has been correlated with cell volume [8] or the size of the interstitial hole in the metal lattice [13] and the free energy of the a p phase conversion. This has been widely exploited to modulate hydride phase stabihty as discussed in Section 9.2.1.
