An X-ray diffraction study is performed of the structure of Al-Ge melts containing 0 at.%, 10 at.%, 20 at.%, 30.3 at.%, 40 at.%, 50 at.%, 60 at.%, 70 at.%, 80 at.%, and 100 at.% Ge near the liquidus line at 1273 K. The melts containing 40 at.%, 70 at.%, and 80 at.% Ge are studied in the temperature range up to 1823 K. The structural factor (SF) curves of the melts have a shoulder on the high-angle side of the first maximum at contents above 20 at.% Ge; the position of the shoulder coincides with that on the SF curve of liquid germanium. An increase in temperature leads to gradual smoothening of the shoulder because of the increase in the structural homogeneity of the melts, which is attributed to the metallization of the residual covalent bonds between germanium atoms. The structure of the melts is found to be microheterogeneous for germanium contents above 20 at.%, which is due to the coexistence of microclusters of liquid germanium and those of the melt with 20 at.% Ge, which provides a satisfactory description of the experimental SF curves in the concentration range 20-100 at.% Ge at temperatures near the liquidus line.

The method of molecular dynamics is used to investigate the effect of monohydric alcohols on the formation of the local structure of ionic liquids based on the dimethylimidazolium cation at T = 400 K. The intermolecular interaction energies are analyzed to find that the increase in the length of the alkyl chain in the alcohol molecule reduces the influence of the solute molecule on the formation of the local structure of the dmim⁺/Cl^--solute molecule systems. An analysis of the radial distribution function shows that the change in the structure and physical characteristics of the solute molecule does not affect the interaction between the hydroxyl group proton of the alcohol molecule and the ionic liquid anions, whose interactions form the hydrogen bond H^alcohol…Cl^- with a length of 2.3 Å.

Thermodynamic characteristics are calculated for aqueous diamine solutions prepared by substituting an amino group for the hydroxyl group of amino alcohols. Patterns are revealed in the change of the structural properties of the mixtures. The correlation between the entropy and enthalpy characteristics of the water-diamine systems and the excess packing coefficients suggests that the universal interactions determine the structural and energy properties of aqueous solutions of the studied diamines. The form of the concentration dependences of the structural and thermodynamic characteristics in the studied systems is found to be symbatic with the data for the mixtures of water with aprotic amides. The reasons for this are discussed by comparing the results with our previously published data for aqueous solutions of aprotic amides.

A method is proposed for determining the hydration number of an individual ion within the approach (V. P. Korolev, J. Struct. Chem. , 55, No. 3, 463 (2014)).

A structural interpretation of the catalytic action of carbon nanotubes on the curing of epoxy polymers is proposed. It is based on the fractal analysis ideas. It is shown that essentially the only factor determining the kinetics of the curing process is the microgel structure characterized by its fractal dimension. The most important conclusion from the obtained results is the fact that the reaction rate dependences on the structural parameters are described by the same correlation for the epoxy polymer curing reaction both in the presence and absence of carbon nanotubes. This means that the catalytic effect of carbon nanotubes consists in a change in the structure of microgels.
