Variational-lagrangian Irreversible Thermodynamics of Initially-stressed Solids with Thermomolecular Diffusion and Chemical Reactions

A GENERAL principle of virtual dissipation in irreversible thermodynamics is applied to a solid under initial stress with small non-isothermal incremental deformations and coupled thermomolecular diffusion and chemical reactions. Dynamical field and Lagrangian equations are obtained directly by variational procedures. In addition, the treatment embodies new fundamental concepts and methods in t...

Composition Control of Low-Volatility Solids Through Chemical Vapor Transport Reactions. I. Theory of Selective Chemical Vapor Transport

A new method is proposed for controlling the composition (nonstoichiometry) of low-volatility inorganic compounds. It is based on the introduction/elimination of one of the components into/ from the low-volatility compound using reversible selective chemical vapor transport. The conditions for composition control through selective chemical vapor transport are deduced from the principles of none...

Low Energy Nuclear Fusion Reactions in Solids

The DD fusion reactions in various materials have been studied, and enhancements in the rate of the D(d,p)T fusion reaction over the Gamow function were clearly seen in the materials. Of particular interest is the fact that the reaction rate of the D+D reactions at 2.5 keV in PdO is 60 times (and in Pd 10 times) larger than in Ti, and the deduced screening energy amounts to 600 eV (300 eV). Fur...

Chemical salt reactions as algebraic hyperstructures

A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations. Hyperstructure theory is studied from the theoretical point of view and for its applications. In this paper, we provide some examples of hyperstructures associated with salt m...
