The chemical constants may therefore be determined directly by the measurement of vapour pressures, especially at low temperatures. Equation (9), which is more general, shows that the chemical constant is determined for a. homogeneous gas as soon as we know A, and C, as functions of temperature, and the vapour pressure at one temperature. These data, especially vapour pressures at very low temperatures, are not very well known at present, and some other method must therefore be used in the determination of the chemical constant. Several such methods have been proposed by Nernst (loc. cit. cf. also Haber, Thermodynamics of Technical Gas Reactions, pp. 88—96 Weinstein, Thermodynamik and Kinetik III., 2, pp. 1064—1074). 

At first, Clara tried to continue her work in chemistry. She attended chemistry seminars and events, translated two articles from English to German, and helped her husband with his 1906 book, Thermodynamics of Technical Gas Reactions. In an unusual move by a German scientist at the time, Haber dedicated the book to her To my loving wife Clara Haber, Ph.D., thanks for the quiet helping work. ...

Haber s work embraced the physical chemistry of gas reactions, following on from the equilibria studies of Le Chatelier and other chemists. Furthermore, Haber, in common with many leading German academic chemists, was well aware of the rewards that might accrue from successful industrial application of laboratory results. Haber s acute awareness of the industrial potential came over in his 1905 book Thermodynamik technischer Gasreaktionen (published in English as Thermodynamics of Technical Gas Reactions) His credentials and background were well suited to the needs of BASF.

The first five years of the new century were Haber s most productive period, both in terms of the total number of publications (almost fifty) or the variety of topics he researched. He pursued different kinds of electrochemical studies (ranging from electrolysis of solid salts to the invention of the glass electrode for determining the acidity of liquids), researched the loss of energy by various prime movers (steam engines, turbines, internal combustion engines), and probed the luminous inner core of the Bunsen flame. In 1905 he published a book on the thermodynamics of technical gas reactions, which was soon translated into English. ... 

NaCl, interact with the sulphur and vanadium oxides emitted from the combustion of technical grade hydrocarbons and die salt spray to form Na2S04 and NaV03- These conosive agents function in two modes, either the acidic mode in which for example, the sulphate has a high SO3 thermodynamic activity, of in the basic mode when the SO3 partial pressure is low in the combustion products. The mechanism of coiTosion is similar to the hot coiTosion of materials by gases widr the added effects due to the penetration of tire oxide coating by tire molten salt. 

Abstract. This section is an introduction into materials that can be used as Phase Change Materials (PCM) for heat and cold storage and their basic properties. At the beginning, the basic thermodynamics of the use of PCM and general physical and technical requirements on perspective materials are presented. Following that, the most important classes of materials that have been investigated and typical examples of materials to be used as PCM are discussed. These materials usually do not fulfill all requirements. Therefore, solution strategies and ways to improve certain material properties have been developed. The section closes with an up to date market review of commercial PCM, PCM composites and encapsulation methods.

It is known that the less irreversible the chemical reactions, the closer they occur to the thermodynamic equilibrium. Unfortunately, the equilibrium of technical combustion processes is usually at such high temperatures that the materials which enclose the reaction volume cannot withstand these temperatures. 

Capillarity — (a) as a branch of science, it concerns the thermodynamics of surfaces and - interfaces. It is of utmost importance for - electrochemistry, e.g., treating the electrode solution interface (- electrode, - solution), and it extends to several other branches of physics, chemistry, and technical sciences [i]. The thermodynamic theory of capillarity goes back to the work of Gibbs, (b) In a practical sense capillarity means the rise or fall of a liquid column in a capillary caused by the interplay of gravity and -> interfacial tension and also phenomena like capillary condensation [ii]. 

Interactions between soluble polymer and colloidal particles control the behavior of a large number of chemical products and processes and, hence, their technological viability. These dispersions have also attracted considerable scientific interest because of their complex thermodynamic and dynamical behavior—stimulated by the synthesis of novel polymers, improved optical and scattering techniques for characterization, and a predictive capability emerging from sophisticated statistical mechanical theories. Thus, the area is active both industrially and academically as evidenced by the patent literature and the frequency of technical conferences.
