Sialons — Promising Refractory and Ceramic Materials

Available data on the chemical composition and structure of sialon phases are reviewed. Properties of the phases and their potential applications are discussed.     

Solid Solutions in the LnAlO3–CaTiO3 (Ln = Dy, Y, Lu) Systems

The phase equilibria in the LnAlO₃–CaTiO₃ (Ln = Dy, Y, Lu) systems are investigated and their phase diagrams are constructed for the first time. The thermal stability of the prepared solid solutions with a perovskite structure is studied.     

Dual-purpose technologies in view of diversification of the military-industrial complex of Russia

Current problems in scientific-information support of the process of diversification of the military-industrial complex (or defense-industrial complex, DIC) of Russia are considered, which can facilitate the effective usage of dual-purpose technologies in various civilian fields of the national economy. In this context, the program of the 7th Specialized Exhibition “Dual-Purpose Products and Technologies: DIC Diversification,” which was held in Moscow in October 2006, is analyzed.     

Undesirable sensory properties of the dried pea (Pisum sativum). The rôle of saponins

The rôle of saponins in the undesirable sensory properties of the dried pea P sativum is reported. The sensory properties of isolated soyasaponin I are defined and described as bitter, astringent and metallic. The distribution of saponin in various air-classified pea flour fractions shows that the protein-rich fraction may contain sufficient saponin to cause undesirable tastes.
