Ordering in lattice gases at low temperature

We show that for generic short-range classical lattice gas models the third law of thermodynamics holds-entropy goes to zero with temperature. The most fundamental aspect of low-temperature matter is its highly ordered (crystalline) structure, which distinguishes it from the fluid state and is necessary for most of the characteristic features of solids. Attempts to discover the causes of this o...

An Empirical Investigation of Value Ordering for Finding All Solutions

Traditional backtracking search algorithms for solving constraint satisfaction problems select a variable and then construct a separate branch for each value in the variable’s domain: the order in which the values are assigned then has no effect on the overall search, when finding all solutions. Constraint solvers such as ILOG Solver and ECLPS instead use binary branching in constructing search...

Investigation of Complexation Mechanisms in Some Cation Solutions

Metal cations represent a considerable part among surface water and land pollutants. Industrial and agronomic effluents, containing in the most cases mercury, cadmium, lead and other cations, until now have been treated by mechanical, physicochemical and biological methods. Biological treatments are the most effective and economically suitable method. Anyway, even biological treatment could not...

Cation Ordering Transformations

Single-phase perovskites were formed in the (1−x)Ba(Zn1/3Nb2/3)O3–(x)La(Zn2/3Nb1/3)O3 system for compositions with 0.0 ≤ x ≤ 0.6. Although the stability of the trigonal ‘‘1:2’’ ordered structure of the Ba(Zn1/3Nb2/3)O3 end member is very limited (0.0 ≤ x < 0.05), low levels of lanthanum induce a transformation to a cubic, ‘‘1:1’’ ordered structure that has a broad range of homogeneity (0.05 ≤ x...

An Iridatropylium Cation: Investigation of Electronic Structure

A study of the [C6 H6 Ir(PH3 )3 ]+ iridatropylium cation structure based on frontier orbital analysis, thermodynamic analysis, and natural bond orbital (NBO) theory is the main aim of the present research. Also, HOMO, LUMO energies, hardness, electrophilicity and chemical potential were calculated. Structural analysis indicated the optimized geometry shows a good agreement with the experimental...
