Liquid nonconventional structures

Details of applicable methods of statistical analysis of experimental data about thermophysical properties of gases and liquids are given in Refs. [0.4, 0.5, 0.29, 0.32, 1.3, 1.4, 3.2, 3.3, and 4.3]. The derivations of experimentally substantiated equations of state of the form (0.7) and (0.8) for Freons-21, -22, and -23 are given and discussed in the following chapters of the present handbook. Short commentary is given on references in which equations of state of nonconventional structure are derived for freons of the methane series under consideration. The specific searching techniques for the coefficients are also given there. 

This indicates that some kind of structure will be present in liquid water surrounding CH4 or alkane molecule, which would be indicative of hydrate structure (Tanford, 1980). These data are of current interest in the future (from nonconventional reservoirs) gas recovery from methane hydrate reservoirs. 

These metal-amine complexes are stable toward moisture and are soluble in organic solvents, leading to liquid precursors with appropriate viscosities for their deposition on substrates. Metal oxide thin films have been prepared from these amine-based precursors, including complex oxide thin films of titanium or bismuth-based perovskites, among others. The molecular structures of the titanium-amine and bismuth-amine complexes synthesized in a solution are shown in Scheme 27.6 [25-27]. In addition, the dative bond from the nitrogen toward the metallic center incorporates new functionalities into these types of molecules, such as photosensitivity, that can be used for nonconventional methods of synthesis of metal oxide thin films.
