The article is devoted to the research and working out of calculation method of thermodynamic data and phase diagrams of pentonary alloy materials of low-melt
The equations for evaluation of the stationary state of lactic acid microbiological synthesis have been received. The kinetic dependencies for specific biomass growth rate, consumption of the substrate are given. The particular qualities of growth of homofermentative lactic acid producer Lactococcus lactis CH5 depending on the composition nutrient medium: glucose and yeast autolysate concentration are examined. The influence of the method of cultivation on the productivity and the speed of the lactis acid synthesis are analyzed
Data of the application of researches of vegetative components in reception of drinks from dairy whey of a functional purpose are shown
In the article, we have investigated a number of characteristics of the sorption materials, the possibility of their use for the treatment of surface and waste water from oil and oil products. The rules of the cleaning oily water, the analytical solution for sorption purification process that takes into account the processes of filtration and sorption are listed. We have also estimated sorption capacity of sorbents and analyzed factors that influence it; the optimal conditions of the sorption process, depending on the conditions and the facilities for cleaning are sorted out. The possibility of purification of oil-contaminated water from heavy metal ions with the synthesized non-organic sorbent is shown
3-Pyrrol-1-ylthieno[3,2-b]pyridin-2-carboxylic acid[(phenyl, 1,3-benzodioxol-5-yl)methylen]-hydrazides were synthesized by the reaction of
3-pirrol-1-ilthieno[2,3-b]pyridine-2-carbohydra-zides with aromatic aldehydes
The present review highlights the theoretical founda-tions of electric activation of aqueous solutions, their characteristics and properties
In the article we have estimated sorption capacity of sorbents and analyzed the factors influencing it; we have also selected the optimal conditions for the sorption process, depending on the circumstances and nature of the treatment facilities. The possibility of purification of oil-contaminated water from heavy metal ions synthesized inorganic sorbent has been shown
The method of nanoemulsions obtaining with acoustic chemistry method has been considered in the article, the nanoemulsion formula has been found. The researches for emulsion stability and particle sizes determination have been fulfilled. The antioxidant effect of the obtained emulsion and a possibility to use it in meat-vegetable products have been researched
Correlations between values of the differences of first
potentials ionization of atoms and molecules (ΔE) and
valency angels α for three coordinated molecules of
types ЭХ3 (Э=N, P, As, Sb are carried out; X=F, Cl,
Br, I, CH3), and also ЭХ2 (Э=O, S, Se, Te;
X = CH3, SiH3, GeH3) are described in this article.
It is shown, that the entered value ΔE can serve as
additive measure of change of the valency angle α in
the basic and raised stances. We have also established
that the functional dependences correlate with changes
in the of hybridization of orbitals and the R
parameters characterizing the interaction of electronic
pairs near the central Э atom
In the article we have optimized reaction conditions of furfurilidenatseton with epichlorohydrin in the presence of a catalyst of tin chloride and held hydrogenation of double bond of 2-methylene -2 - [(2-furyl]-X-1,3 – dioxolan; we have also given the
biological activity of some unsaturated furan 1,3- dioxolans
