Chromatographic Determination of Azodyes Based on Carbo- and Heterocyclic Alpha-Dicarbonyl Compounds 10.22184/2227-572X.2025.15.1.58.62
Over the last 20 years, liquid chromatography has become one of the most used methods for the investigation of natural and synthetic colorants in various objects. It is very important to control the content of azo dyes, based on phenanthrenequinone and hydrazine derivatives, which can potentially have a negative impact on human health. This article is devoted to the possibility of chromatographic separation of some azo dyes based on carbo- and heterocyclic alpha-dicarbonyl compounds. Optimal conditions for the analysis (solvents, eluent and its flow rate, temperature, wavelength) are selected; detection limits and linear ranges of determination of the studied compounds are established.

Development of a Method for Accelerated Quality Control of Electrochromic Devices doi.org/ 10.22184/2227-572X.2025.15.1.50.56
This article presents a method for non-destructive quality control of architectural electrochromic devices capable of regulating light and heat flows in residential premises. A distinctive feature of these devices is their high thermal efficiency, which is 80% higher than that of conventional double-glazed windows. However, the issue of quality control of electrochromic devices, which was previously based on long-term cyclic tests, has remained unresolved. The result of the study was a new method that allows reducing the diagnostic time of electrochromic products from several weeks to 40–50 minutes.

Birth of the Colloidal Electrochemical Laboratory. To the 95th Anniversary of the Frumkin IPCE RAS The Colloidal Electrochemical Laboratory (LACE), from which the Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences grew, was organized by academician Vladimir Alexandrovich Kistyakovsky in Leningrad in 1929. When preparing the material, the author studied the published documents of the Presidium of the USSR Academy of Sciences from the Russian State Library and documents from the Archive of the Russian Academy of Sciences.
