Tkacheva T.A., Salikova A.N. RECEIVING, ESTABLISHMENT OF STRUCTURE AND DETERMINATION OF THE ETILENDIAMINOV SPECTROSCOPIC PROPERTIES OF THE S DIPIRIDOHINOKSALINOM CO (II) AND NI (II) COMPLEXES [№ 10 ' 2015] Complex transition metal compounds are of interest as systems with directional charge transfer and energy. It is known that the d-elements such as palladium and platinum to form such compounds. For the first time metal chelate compounds of Co (II) and Ni (II) with dipiridohinoksalinom of interest for further research. Improved previously known methods for the synthesis of ligands and metal complexes thereof. The physical parameters of ethylenediamine complexes of Co (II) and Ni (II) with dipiridohinoksalinom. Low temperature melting intervals confirm purity of compounds obtained. Information on the solubility of the compounds needed for further research. IR spectroscopy is informative enough to establish the structure of the compounds obtained, finding connections and functional groups in their structure. Confirmed structure of the synthesized compounds. Changes in the set of functional groups by complexation. The optical properties of the substances. Comparison of the absorption spectra of the free ligands and metal complexes indicates that complexation leads to a shift of the maxima in the spectrum at longer wavelengths (bathochromic shift). Type is set to electronic transitions in accordance with the Koopmans theorem. It is shown that electronic transitions of the metal-ligand absent.
Belousov A.A., Salikov M.P. INCREASE OF POWER EFFICIENCY OF THE SINGLE-PHASE ASYNCHRONOUS ENGINE WITH THE DISCONNECTED STARTING WINDING [№ 1 ' 2013] It is shown that properties of the single-phase asynchronous engine with disconnected starting winding can be improved considerably without its alteration, having left its starting winding after start-up included in network through the condenser of small capacity. The offered scheme is expedient for using for engines which are in operation, and at engine design.
Salikova S.P., Stadnikov A.A., Nikiyan A.N. ATOMIC-POWER MICROSCOPE AS A NEW OPPORTUNITY OF CARDIOMYOCYTES STUDYING [№ 1 ' 2003] The article considers the atomic-power microscope work main principles and its application results when studying rats' myocardium cells surface. Atomic-power method advantages are mentioned. Atomic-power method application allows not only to visualize the cell surface but to gain information on its different properties.
