Low-Resistance Bi/Pb Ceramics Containing Ts = 295К-315k Phases Synthesized In A Solar Furnace (Parkent), Gulamova Dilbara, Gulamov Timur
CHEMISTRY AND CHEMICAL ENGINEERING
The aim of this work is to obtain bulk textured superconducting ceramics based on glass-crystalline precursors of the Bi1.7Pb0.3Sr2Ca(n-1)CunOy (n=5-9) series. Technologies for obtaining superconducting materials are presented. The advantages of melt methods and “Super Fast Aloys Quenching–T” technology is shown. Compositions, methods of synthesis and study of properties of precursors and ceramics obtained by solar energy are presented. The interrelation of the morphology of glass-crystalline precursors and superconducting ceramics based on them is revealed. It is shown that nano-sized nuclei are the basis on which superconducting phases with Ts = 295-315K are formed as a result of the peritectic …

CHEMISTRY AND CHEMICAL ENGINEERING
With the aim of determination of electronic and geometrical structures of mixed-ligand complexes, theoretical modeling of the structures of coordination compounds of transition metals with dialkyldithiophosphate chelating ligands with aminobenzimidazoles carried out using quantum chemical methods. Using BIOVIA Materials Accelrys Studio 2017 software packages, the geometry, electron density distribution, and frontier orbitals calculated for the mixed ligand complexes Zn(II), Cu(II), Ni(II), Fe(III), which is necessary for understanding the electronic structure of coordination compounds with chelating ligands.

CHEMISTRY AND CHEMICAL ENGINEERING
Considering that many derivatives of bis carbamates have different biological activity, it was intuitive to produce a targeted synthesis of new derivatives of bis carbamates by the interaction of hexamethylene diisocyanate with 3,5-diode-4-hydroxybenzoic acid and 2,4,6-triiodophenol (1: 2 mol, respectively) in freshly distilled dry pyridine at 95-110 оC for 6 hours, the corresponding derivatives were obtained - methylene bis carbamates. Experimental studies have been conducted to identify the acute toxicity and radiopaque properties of the synthesized new N, -hexamethylene bis (2,6-diode-4-carboxyphenylcarbamate).
