The Chemical Industry Chooses Advanced Development The past year, 2025, marked an anniversary for the international exhibition Chemistry. Exactly 60 years ago, the USSR began introducing chemical technologies into the national economy: their readiness was reviewed at the first exhibition in this industry. Years have passed, and the international exhibition Chemistry has transformed into a meeting place for chemical product and service manufacturers and equipment suppliers with consumers from around the world. In this article, we will discuss how it was held in 2025 at its new location – the Timiryazev Centre Exhibition Complex.

Artificial Intelligence Helps Discover Substances and Materials. Second Conference Artificial Intelligence in Chemistry and Materials Science
Is it possible to teach a neural network to recognize the structure of a substance from a photograph of crystals, speed up instrument data processing tenfold, and enhance materials discovery by thousands of times? Scientists sought answers to these questions at the second scientific conference «Artificial Intelligence in Chemistry and Materials Science,» which took place from November 17 to 21, 2025, at the N. D. Zelinsky Institute of Organic Chemistry of the Russian Academy of Sciences and became one of the most notable events of the year in the field of digital chemistry.

35 Years of the Analitika Association: Preserving Values While Creating the Future This article explores the key milestones in the development of the Analitika Association of Analytical Centers. It highlights the Association“s key role in establishing an objective and recognized accreditation system in Russia based on international principles. It also highlights the significant work carried out in the field of chemical analysis metrology, translating and adapting documents from several international organizations and developing a national terminology for chemical measurements. The Association“s mission, enshrined in its Charter, and its guiding principles are outlined. The program for annual meetings of the Association“s members, which currently number over a hundred, is described in detail. The role of the website and Telegram channel in its ongoing work is highlighted. The article also discusses the work on issuing regulatory documents for the Technical Committee for Standardization TC 325 Analytical Control, established within the Association.

Digital Transformation

Crystal Chemistry in the Era of Digital Transformation The article examines the impact of digital transformation on crystal chemistry – a discipline originally based on data processing. It traces the evolution of crystal chemistry from solving the inverse problem of interpreting experimental data to explain structure and properties to solving the direct problem of engineering materials with desired properties. The main focus is on analyzing current trends and challenges in the digitalization of two key components of crystal chemistry: the methodological part (obtaining structural data) and the descriptive part (interpreting data). It is shown that the future of crystal chemistry and related fields depends on solving the problem of data reliability and verifiability, as well as on a conscious ethical approach to the application of artificial intelligence and statistical methods. The article highlights the risk of devaluation of fundamental knowledge and expertise against the backdrop of a growing number of publications based on low-quality data or superficial analysis. The article serves as a critical review of the current state and challenges facing crystal chemistry in the era of science“s digital transformation.

PLGA Nanospheres with Incorporated Warfarin Warfarin is a highly effective orally administered anticoagulant. However, its use is limited by the high risk of bleeding. Its extremely low solubility in biological fluids is another limitation of its practical use. Consequently, it has low bioavailability. This study proposes a method for increasing the hydrophilicity and bioavailability of warfarin by producing a suspension of nanospheres in which the drug is incorporated into a lactic-glycolic acid copolymer shell. This method also prevents bleeding because the drug is released gradually, resulting in a prolonged action. The study examined the physicochemical properties of the suspension and the kinetics of drug release.
