Pages: 675-678

Abstract >>
By analogy with thermodynamic notions, implying that the possibility for a reaction to proceed is determined by Gibbs' energy, which is equal to the difference of the energies for the final and initial products, it is proposed to calculate the difference of the sums of mean orbital electro-negativities for the final an initial products. A linear correlation has been established between Gibbs' energies of reactions and the mentioned differences, on the basis of vast experimental material for various reaction types. This correlation can be used to estimate the possibility of a reaction between the compounds for which thermodynamic data are unknown, in particular for complicated multi-component compounds.

Abstract >>
Physicochemical properties of non-equilibrium solid solutions in metal systems obtained mechanochemically are investigated by means of high-resolution microscopy, X-ray diffraction and differential scanning calorimetry (DSC). It is demonstrated that nano-crystalline non-equilibrium solid solutions possess the excess free energy due to the presence of non-equilibrium non-stoichiometric defects and high density of inter block boundaries. The whole set of these defects creates synergetic effect in chemical activity.

Abstract >>
A fibrous material composed of filamentary crystals of iron carbide Fe3C or metal iron encapsulated in graphite shells is synthesized. Combined investigation of the structure of the obtained material is performed by means of electron microscopy, powder X-ray diffractometry and Mössbauer spectroscopy. It is discovered that current-voltage characteristics of auto-emission properties of nanoparticles differ from the properties of pure carbon nano-tubes, which is explained by different adsorption characteristics of these materials.

Abstract >>
Iron (II) complexes with 1,2,4-triazoles are promising thermochromic materials. New complexes of iron (II) perrhenate and dodecahydro-closo-dodecaborate with 1,2,4-triazole (Htrz) and 4-amino-1,2,4-triazole (NH2trz) of the composition FeL3An × mH2O (n = 1, 2; m = 4, 5) are synthesized and investigated. The compounds are studied by means of magneto-chemistry, XPA, electron and IR spectroscopy. Magnetochemical data show that the complexes possess 1A1 <=> 5T2 spin transition. The spin transition is accompanied by thermo-chromism (change of colour from pink to white).
