As part of the scientific and industrial forum "Golden Valley", which is held by Novosibirsk State University, employees NSU Center for Artificial Intelligence presented a framework for managing artificial intelligence models.

"Our framework is for managing and testing datasets and AI models, which must be done before they are included in any workflow. To make this more clear, we also showed examples of the framework's operation with several datasets we already have," said Evgeny Pavlovsky, PhD, a leading researcher at the NSU Center for Artificial Intelligence.

One such example is a project implemented with the State Public Scientific and Technical Library.

The framework was loaded with digital library card data and its markup, and a model for card recognition and bibliographic information structure recognition, created by the center's own staff, was tested.

"We are currently in the process of handing over the framework to the client. Its implementation will significantly automate the work of the State Public Scientific and Technical Library staff in creating new cards. In the future, we plan to add an algorithm to the framework that will allow it to scan a new book and automatically extract the necessary bibliographic information from it, without the involvement of a library employee," explained Evgeny Pavlovsky.

There will be some “advantages” for readers, first of all, the process of finding the necessary books published before 2000 will be significantly simplified.

"Currently, this task requires a rather complex approach. For example, it took me about half an hour to find a book about Al-Khwarizmi, published in Tashkent in 1968. But I was very motivated to search. Modern users don't always spend 30 minutes searching for a single book. Therefore, with our framework, we've significantly simplified this process; you can find the book or article you need much faster, without resorting to specialist help," Pavlovsky emphasized.

There are other examples of the framework's use, all related in one way or another to smart city technologies, which are the specialty of the NSU Center for Innovative Research. This primarily applies to developers of artificial intelligence models, those who have a good understanding of their clients' needs and are currently in the model development stage. For example, when modeling heat distribution in a city, the client clearly understands the objectives, structure, and capabilities of the city's heating networks and the entire housing and utilities infrastructure, but also needs a model to optimize certain processes and parameters.

As is well known, some AI models can sometimes produce incorrect data, or, as they say, hallucinate. In such cases, a framework will be needed that allows developers to test models and understand which ones are usable and which are not.

But, as the developers emphasize, the range of its potential applications is much broader. This was confirmed by the interest the development generated among visitors to the exhibition organized as part of the Golden Valley forum.

For the first time in Russia, a ready-made air handling unit with a recuperator offering absolute frost resistance—it can withstand temperatures down to -90°C—has been introduced. The unit can be used in both individual construction projects and large industrial facilities. It reduces peak and overall building energy consumption for temperature maintenance by 70% year-round, significantly reducing costs not only during building operation but also during the design phase. The control electronics for this unit were developed by students and graduates of the NSU Faculty of Information Technology (FIT).

To reduce heat loss during ventilation, recuperators are used—heat exchangers that operate by transferring thermal energy from exhaust air to supply air supplied to the room. This process heats or cools the supply air, saving energy on heating and cooling the air. However, in freezing temperatures, existing recuperators freeze over, significantly increasing the energy costs of heating the supply air. This led to the idea of creating an innovative recuperator that combines the features of two main types of such devices—plate and rotary.

"All recuperators freeze—it's a matter of physics. But unlike others, our recuperator—a heat exchanger—is designed so that, rotating at a specific speed—approximately one revolution per hour—it moves frozen areas from the cold zone to the warm zone, where they thaw naturally," said Vladimir Fedorov, founder of the developer, Giplar, and a graduate of the Physics Department at NSU.

Novosibirsk developers have created the world's first recuperator with continuous self-defrosting without compromising efficiency. It is used to produce air handling units with a consistently high recuperation efficiency of 70%, and their efficiency is unaffected by freezing temperatures (down to -90°C) or the humidity of ventilated spaces. This reduces peak and overall energy consumption of buildings for temperature maintenance by 70% year-round.

The next step was to develop control electronics to ensure the coordinated operation of all the system's components. None of the ready-made solutions available on the market were suitable, as the recuperator was unique, so a custom control module had to be developed. This task was tackled by graduates and students of the NSU Faculty of Information Technology, led by Ilya Epishin.

"Our electronics control the heat exchanger's operation: our task was to monitor the inlet and outlet temperatures, control the power of the supply and exhaust fans, rotate the heat exchanger rotor at a specific time, and provide feedback on its position to detect any issues that may arise during rotation or during operation; and monitor the filter status using a set of sensors. We also implemented several operating modes, one of which is "Breeze," which allows us to configure the heat exchanger so that, at temperatures close to the dew point (when water vapor condenses into liquid), the air in the room is cooled using the laws of physics, rather than the air conditioner," explained Ilya Epishin.

FIT students, under the guidance of Ilya Epishin, developed a control board, wrote code for the microcontroller, programmed the board and display, and developed the interface, which required some knowledge of industrial design. They used the open-source LVGL library.

"The unique feature of the control electronics is its modular architecture, meaning it can be expanded with any number of modules, increasing its functionality, and adding an additional board. The architecture is based on a pass-through bus with a desi-chain mechanism, which enables the integration of various modules in our design. This year, my student Matvey Potapov, who also actively participated in this project, will be defending his thesis on this topic. This approach allows the controller to automatically detect an additional module when connecting it, and if the code supports it, new functions become available to the user or the system's operating logic changes automatically. It's somewhat reminiscent of plug-and-play on a computer, but applied to industrial automation. This fits well with the system itself—the heat exchanger is also modular, and for larger spaces, devices can be assembled from several modules, increasing the air volume that can be passed through it and allowing for cost-effective use in industrial facilities," Ilya explained.

The introduction of such air handling units will allow for a wider geographic reach, for example, in regions of the Far North, where recuperators are not used due to severe frosts. However, reducing heating costs is a pressing issue in these areas. This will also reduce building costs even at the design stage, when the innovative air handling units used allow for lower energy consumption requirements.

The 4th School of Young Scientists on Synchrotron Research Methods in Materials Science is taking place at Novosibirsk State University from November 13-15. The project is supported by the Federal Scientific and Technical Program for the Development of Synchrotron and Neutron Research. The event was organized by the Siberian Branch of the Russian Academy of Sciences, the Boreskov Institute of Catalysis, the Siberian Ring Photon Source (SKIF) Collective Use Center, and Novosibirsk State University. Over 100 young researchers from Novosibirsk, Moscow, St. Petersburg, Kaliningrad, Koltsovo, Ufa, Tomsk, Barnaul, Dolgoprudny, Kemerovo, Krasnoyarsk, Yekaterinburg, and Troitsk participated in the school.

NSU Rector and RAS Academician Mikhail Fedoruk welcomed the School participants. He noted that this is the second year in a row that the event has been held at NSU, but this year, the School participants will be hosted in a new classroom building, which opened on September 1st.

"The school's program is becoming more extensive year after year, and the geography of its participants is expanding. I'm confident that with the commissioning of SKIF, the intensity and richness of the events at future schools will only increase. The current school's program offers unique content, including master classes from leading experts in synchrotron radiation research, as well as lectures from leading scientists," said Mykhailo Fedoruk.

The work of the School opened with a lecture by the chief researcher of the SKIF Center for Use, Associate Professor of the Department of Solid State Chemistry of the Faculty of Natural Sciences of NSU and the Department of Physical Methods for Solid State Research of the Faculty of Physics of NSU, Doctor of Physical and Mathematical Sciences Jan Zubavichus, “Source of synchrotron radiation of the SKIF Center for Use: stages of commissioning and implementation of the Scientific Program,” in which he highlighted the main milestones of the construction of SKIF, introduced its design, instrumentation and technical equipment, visually presented the general scheme of the megascience installation with first-stage stations and spoke in detail about each, especially focusing on station 1-7 “Basic methods of synchrotron diagnostics”, intended for educational, research and innovation activities, as well as to increase the efficiency of the educational process and solve research problems for NSU students using the capabilities of a modern synchrotron radiation source. At this experimental station, it is planned to jointly implement several research methods: powder and single-crystal X-ray diffraction, X-ray absorption spectroscopy and X-ray fluorescence analysis. This research complex will allow solving a wide range of scientific problems for various fields of science, including physics, biology, chemistry, geology, archeology and medicine and will become a main element in the practical training of scientific and technical personnel for synchrotron research. In their research, NSU students will be able to use equipment from other stations, in particular, a wide range of high-temperature cells for conducting in situ/operando experiments, unique superconducting undulators developed by the BINP SB RAS for generating superbright beams with a high degree of spatial coherence in the energy range 3-12 keV, as well as a unique electromagnetic undulator with switchable polarization developed by the BINP SB RAS. It is possible to generate X-ray beams with a circular cross-section; the station also has unique optical elements for focusing X-ray beams to submicron sizes developed by IKBFU. Kant and IPM RAS and unique ultrafast X-ray detectors for monitoring fast development processes at the Institute of Nuclear Physics SB RAS. The areas of research for which the station is designed are wide and varied: functional chemical technologies and materials, catalysis, geology, ecology, structural materials and materials for energy, structural biology, pharmaceuticals.

Completion of this experimental station is scheduled for December of this year. At that time, work on the Generation 4 synchrotron radiation source will be completed, and the integrated commissioning phase and design parameter acquisition will begin.

Each day of the school begins with plenary lectures from leading experts in the field of synchrotron radiation. Alexander Trigub, PhD (NRC Kurchatov Institute, Moscow), spoke about the study of local atomic and electronic structure using X-ray absorption spectroscopy; Ivan Bataev, Doctor of Engineering (Novosibirsk State Technical University), discussed the use of synchrotron radiation in specialized materials analysis; and Konstantin Kuper, PhD (National Research Center of Nuclear Physics, Siberian Branch of the Russian Academy of Sciences), discussed X-ray microscopy and tomography using synchrotron radiation.

On the final day of the school, there will be lectures by Evgeny Sterkhov, PhD (Chemistry), (N.A. Vatonin Institute of Metallurgy, Kyrgyz Republic, Russian Academy of Sciences, Yekaterinburg), on the analysis of the symmetry of modes of distorted structures of layered perovskites, and Igor Chernykh, PhD (Physics and Mathematics), (Institute of Computational Mathematics and Mathematical Geophysics, Siberian Branch of the Russian Academy of Sciences), on how artificial intelligence can help in chemistry and materials science.

The plenary lectures will be followed by presentations by young scientists – students and postgraduates from Novosibirsk State University, Boreskov Institute of Catalysis SB RAS, International Tomography Center SB RAS, Budker Institute of Nuclear Physics SB RAS, Voevodsky Institute of Chemical Kinetics and Combustion SB RAS, A.V. Nikolaev Institute of Inorganic Chemistry SB RAS, A.V. Rzhanov Institute of Semiconductor Physics SB RAS, M.A. Lavrentiev Institute of Hydrodynamics SB RAS, SKIF Collective Use Center, Tomsk Polytechnic University, Federal Research Center for Coal and Coal Chemistry SB RAS (Kemerovo), V.V. Engelhardt Institute of the Russian Academy of Sciences (Moscow), and others. This year, a representative of the Republic of Belarus, Ivan Grekov, from the Scientific and Practical Center for Materials Science of the National Academy of Sciences of Belarus (Minsk), is participating in the school.

"We consider presentations by young researchers an important part of our school, whose goal is not only to provide young researchers with the opportunity to attend lectures by recognized experts in the field but also to present the results of their research. Therefore, the speakers include not only graduate students but also fourth-year undergraduates. For many of them, this is their first experience of publicly speaking to the scientific community, and this is crucial, as the ability to present their research results to an audience is a crucial skill for every scientist. Some young researchers, on the other hand, are presenting reports on their work over the past year, as this school is a logical continuation of the previous one. However, the program of each school differs from previous ones, so new topics are added and the lineup of speakers is updated," explained Sergei Tsybulya, Head of the Department of Physical Methods for Solid State Research at the Faculty of Physics, Chief Researcher of the Catalyst Research Department at the Boreskov Institute of Catalysis, and Doctor of Physical and Mathematical Sciences.

As part of the School, young scientists will present approximately 40 oral and more than 20 poster presentations.

Master classes are an important part of the School, and young scientists are particularly interested in them. While at previous Schools they were held in parallel, this year the organizers decided to hold them sequentially: participants expressed a strong desire to attend several master classes at once, or even all of them, as part of the School's program. This year's School will feature four master classes: "Refining Structural Models Using Powder Diffraction Data in the GSAS-II Software Package," "Creating Models of One-Dimensional Disordered Crystals and Calculating X-ray Diffraction Patterns Based on Them Using the XD1DD Software," "Processing X-ray Photoelectron Spectroscopy Data," and "Determining Parameters of the Local Atomic Environment from EXAFS Spectra." During the master classes, young researchers are taught, using practical examples and specific software, how to solve problems they will encounter in their work using synchrotron radiation methods.

The SKIF Center for Collective Use will be operational at the end of next year. It will be able to accommodate 2,000 scientific groups annually, so developing a user community is particularly important for us. This community should be comprised of researchers who understand how to use synchrotron radiation and how to use it to solve various interdisciplinary problems. I am confident that virtually every scientific and educational organization would be interested in collaborating with the SKIF Center for Collective Use, so it is crucial to provide the scientific community with the fullest possible information about its capabilities and to train specialists capable of using them. This school fully meets these goals. We value our ongoing and effective collaboration with NSU in organizing and developing the school's program and believe that this work has become increasingly important.

The school's program offers a balanced combination of theoretical knowledge and practical training. It is relevant and modern. The lecture program is very well-designed, covering various synchrotron research methods and the basics of synchrotron physics. Master classes on key X-ray synchrotron methods, using specialized data processing software, are offered in NSU computer labs. These classes are taught by world-class specialists, leading Russian experts in the relevant fields. This is crucial for preparing the SKIF Center for Collective Use's user community, said Jan Zubavichus.

The school is a satellite event of the International Conference "SKIF Center for Collective Use Users Congress: Advanced Research Using Synchrotron Radiation," which will be held from November 17 to 21 at the Boiling Point Center in Novosibirsk Academpark.

Today, as part of the 3rd Zolotaya Dolina Scientific and Industrial Forum, an agreement was signed between the Sistema Charitable Foundation and Novosibirsk State University. The two organizations plan to actively collaborate in the field of education. This collaboration can be considered to have kicked off with the MTS True Tech Day conference, "The World of IT from Within," which the MTS digital ecosystem and the Sistema Charitable Foundation are holding at the Zolotaya Dolina site as part of the regional sociocultural festival, Sistema FEST.

"One of the key principles of the Sistema Charitable Foundation in supporting young talent is systematic collaboration with educational institutions in the regions. We plan to continue our work with Novosibirsk State University, which boasts a strong scientific school, to facilitate the development of students' scientific and technical potential and professional self-fulfillment," said Larisa Pastukhova, President of the Sistema Charitable Foundation and Corresponding Member of the Russian Academy of Education.

"The university's strategy envisions actively developing collaboration with industrial partners, in various formats—from the joint development of new technologies and solutions to the implementation of educational programs. To address modern challenges and solve the problems facing the Russian economy, it's important for companies to actively engage in the educational process and directly participate in training highly qualified specialists through internships and joint projects. In this way, we jointly build a talent pool that determines the competitiveness of the region and the country in science and technology. The festival, held at NSU, is a powerful model for such partnerships between education, science, and industry," commented Mikhail Fedoruk, Rector of Novosibirsk State University.

Novosibirsk, November 13, 2025: Today, the 3rd Scientific and Industrial Forum "Golden Valley 2025" opened at Novosibirsk State University. It is a key event in Siberia, bringing together representatives of science, industry, high-tech companies, and government agencies. This year, the forum brought together over 1,000 participants from across the country, including Khabarovsk, Barnaul, Kemerovo, Tomsk, Omsk, Kazan, Rostov-on-Don, St. Petersburg, Moscow, and other cities.

"This forum continues the glorious traditions established here in Akademgorodok by the founding fathers—the idea of close collaboration between education, science, and industry. The forum's overarching theme is the 125th anniversary of Mikhail Alekseevich Lavrentiev. His contribution to science and the organization of science is, of course, invaluable for our entire country. November 19 marks the birthdays of two great scientists and statesmen—Mikhail Alekseevich Lavrentiev and Mikhail Vasilyevich Lomonosov. Therefore, holding the 'Golden Valley' forum on the eve of this momentous occasion is highly symbolic," noted NSU Rector and RAS Academician Mikhail Fedoruk.

The forum will discuss technology trends in key areas, divided into six sections: "Aviation and Unmanned Systems," "Microelectronics and Critical Technologies," "Energy," "Industrial Innovation," "Medicine and Longevity," and "Smart City Technologies and AI." Special attention will also be paid to the role of artificial intelligence in various areas of human activity. The forum will include panel discussions, roundtables, and open lectures.

"The forum's central theme is the anniversary of Mikhail Alekseevich Lavrentiev, the founder of the Siberian Branch. But this year, as we all know, we also celebrate the centenary of Gury Ivanovich Marchuk, who also laid the foundations for scientific fields in Akademgorodok. Since the founding of the Siberian Branch in 1957 and the subsequent establishment of the university, both science and education in our region have developed inextricably. Then, innovative structures—technology parks—began to emerge. Currently, Novosibirsk and Akademgorodok boast several growth areas, including, of course, Novosibirsk State University, Akadempark, and the Siberian Branch of the Russian Academy of Sciences. I am confident that the forum will gain momentum. Novosibirsk is rightly called the scientific capital of Russia; it fully deserves this title and will, I am confident, continue to uphold it," emphasized Dmitry Markovich, First Deputy Chairman of the Siberian Branch of the Russian Academy of Sciences and Academician of the Russian Academy of Sciences.

It's worth noting that this year's event is taking place in the new classroom building, which officially opened on August 29 with the participation of Russian Deputy Prime Minister Dmitry Nikolaevich Chernyshenko. The building accommodates approximately 1,700 students and features four classrooms, one of which, with a capacity of 400, is the largest at NSU. It also houses a research library with a collection of over 1 million books. The building offers excellent conditions for student learning and project activities, as well as for hosting such large-scale events.

"We are honored to bring together the best minds in science, representatives of leading educational institutions, corporations, innovative companies, and industrial enterprises within the walls of Novosibirsk State University, in the heart of our Akademgorodok. This forum is a clear embodiment of our key goal: the integration of academic science, higher education, and high-tech business. The regional government sees its role as purposefully creating an environment conducive to such interaction. We place a special emphasis on supporting technological entrepreneurship and the commercialization of developments. To this end, we are implementing and developing a range of support measures: from grants for startups and incentives for innovative companies to expanding the infrastructure of our technology park. Our shared goal is to build effective 'tech elevators' that will enable Novosibirsk know-how to quickly move from a scientific idea and laboratory prototype to a sought-after product on the global market. It is here, at the forum, that the foundations for their launch are laid," emphasized Vadim Vasiliev, Minister of Science and Innovation Policy of the Novosibirsk Region.

Representatives of leading companies will speak at the forum, including the United Engine Corporation, Gazprom Neft, 2GIS, Novosibirsk Generating Company, and others. On the first day, a strategic session, "Innovations in the Fuel and Energy Sector," will be held, along with a meeting between industrial leaders and the leadership of Novosibirsk State University and SB RAS institutes, with the participation of the Office of the Presidential Plenipotentiary Envoy to the Siberian Federal District and the Interregional Association "Siberian Agreement." The second day will feature a strategic session, "Using Artificial Intelligence Technology to Solve Public Sector Problems," with the participation of the Novosibirsk Region Ministry of Digital Development, and the MTS True Tech Day conference, "The World of IT from Within."

The forum will also feature opening lectures: on the first day, Mikhail Lavrentyev, Corresponding Member of the Russian Academy of Sciences, will deliver a lecture entitled "Academician Mikhail Alekseevich Lavrentyev: Milestones in His Life," while Pyotr Marchuk will speak about the 100th anniversary of Academician Gury Ivanovich Marchuk. On the second day, Academician Sergei Alekseenko will present a lecture entitled "Extreme and Catastrophic Climate Events: Relationships with Energy," and Academician Dmitry Zharkov will discuss how cells repair genes.

The forum's partners included the Siberian Branch of the Russian Academy of Sciences, the Council of Rectors of the Novosibirsk Region, the "Commonwealth. Efficiency. Development" (CED) Business Club of Enterprise Managers, the NSU Alumni Association, the Novosibirsk Academgorodok Technopark, the Sistema Charitable Foundation, and the MTS digital ecosystem. The forum is supported by the Government of the Novosibirsk Region.

Comet 3I/ATLAS is the third interstellar object discovered by the American ATLAS automated telescope system. Unlike the previous interstellar objects—the asteroid 1I/Oumuamua and comet 2I/Borisov—which remained very faint throughout their entire period of visibility, comet 3I/ATLAS is comparatively bright, reaching a maximum brightness of approximately 10th magnitude, making it observable even with amateur telescopes, at least with relatively large ones.

The main feature of this comet is the pronounced hyperbolicity of its orbit, which makes it an interstellar object. The shape of an object's orbit around its center of mass is determined by its eccentricity. If the eccentricity is less than one, the orbit is closed; it can be closer to circular when the eccentricity is near zero, or, conversely, an elongated ellipse if the eccentricity approaches one. The orbits of objects gravitationally "bound" to the Sun are either elliptical (like planets, asteroids, and periodic comets) or near-parabolic. The latter case refers to non-periodic or long-period comets from the hypothetical Oort cloud, which is believed to be a cluster of cometary nuclei surrounding the Solar System at a distance of approximately 100,000 AU. The orbits of comets that fly from this cloud into the solar system have an eccentricity value of about 1 (i.e. their orbit is very close in shape to a parabola), which means that, while in the Oort cloud, they have a near-zero velocity relative to the Sun and generally move around the center of our Galaxy together with the Sun.

Comet 3I/ATLAS has an eccentricity of 6.14. This is the highest eccentricity ever discovered for a celestial body. It indicates that the comet was already moving at a fairly high velocity when it passed through the Oort Cloud, which increased further as it moved further into the inner Solar System. This suggests that this comet does not originate from the Oort Cloud, which would classify it as a Solar System object, but likely originates from another solar system. It encountered the Solar System by chance on its long journey through our Galaxy. It will pass through it and, unlike solar comets, will not remain in the Oort Cloud, but will continue on its way.

The exact origin of this comet is currently impossible to determine, including the star from which it came, as its age is estimated at several billion years, during which time it has traveled a very long distance in orbit around the center of the Galaxy. However, it was likely ejected from a stellar system as a result of gravitational disturbances during its approach to a large planet in that system or to the star itself.

Otherwise, aside from the hyperbolic orbit, 3I/ATLAS is a fairly ordinary comet. Some peculiarities in its composition have been identified, such as the relatively large amount of carbon dioxide it emits, and spectral analysis has revealed the presence of atomic nickel in the absence of iron, although these two elements typically occur in pairs in cosmic objects. However, nothing particularly out of the ordinary has been observed for this comet, either in its composition or appearance. Even some comets in the Solar System are far more unusual in this regard. However, comet 3I/ATLAS still deserves considerable attention from scientists, as its observation and study presents a good opportunity to study the composition and dynamics of an object that has arrived from very distant lands.

The template effect of a small amount of additives of compounds with a similar structure (various saturated carboxylic acids and alkanes) on the process of self-assembly and crystallization of the channel trigonal structure of carbamazepine using a mechanochemical approach, crystallization in solution and melt was demonstrated by a first-year master's student in the Chemistry program and the training profile "Methodological support for physicochemical studies of condensed phases" Faculty of Natural Sciences of Novosibirsk State University (NSU Natural Sciences Department) Daria Zheltikova, under the supervision of Evgeny Losev, a research fellow at the Boreskov Institute of Catalysis SB RAS, senior lecturer in the Department of Solid State Chemistry at the NSU Natural Sciences Department, and candidate of chemical sciences. The key focus of her research was studying the phenomenon of polymorphism and the conditions for the formation of new solid forms of medicinal compounds, particularly carbamazepine, as well as methods for their controlled production. The effect of the compounds examined in the study on carbamazepine had never been previously studied.

Polymorphism is the ability of the same substance to exist in different crystal structures (polymorphic modifications). These structures differ in the arrangement of atoms (or molecules) and may have different physicochemical properties (e.g., solubility, melting points).

"The pharmaceutical industry is focused on studying the conditions for the formation of new crystalline forms of medicinal compounds, investigating their structures and physicochemical properties, and their interconversions. These processes address such important issues as the reproducibility of obtaining the desired substances, establishing the stability of drugs prone to polymorphism, and improving fundamentally important pharmaceutical characteristics: dissolution rate, bioavailability, storage stability, hygroscopicity, and other properties. To screen new crystalline forms, we primarily used a mechanochemical approach. This is a common method for screening the conditions for obtaining new solid forms of molecular compounds. Thanks to the wide range of parameters available for mechanochemical experiments, researchers can comprehensively study a selected system and draw conclusions about the putative mechanism of the processes occurring during the experiment. In recent years, mechanochemical reactions and transformations initiated by mechanical stress have been actively studied using various in situ methods using synchrotron radiation," explained Daria Zheltikova.

The young researcher's object of study was carbamazepine, a drug with antiepileptic and anticonvulsant properties, widely used in the treatment of nervous system disorders. According to the biopharmaceutical classification system, carbamazepine belongs to class II drugs, meaning it has low solubility in aqueous solutions and high intestinal permeability. Currently, five polymorphic modifications of this drug are known, which is quite unique and places carbamazepine in the class of highly polymorphic molecular compounds. Each polymorphic modification has a different crystal structure and molecular packing. In 1987, polymorphic modification II of carbamazepine, which has a trigonal space symmetry group, was first isolated and characterized. A distinctive feature of the crystalline structure of this form is the presence of extended tubular voids (channels) formed by the CH groups of the benzene fragments of the carbamazepine molecules. This substance is a good model object for studying the influence of experimental parameters on the selective production of specific polymorphic modifications and crystalline forms. The knowledge and patterns gained can be further transferred to other systems prone to polymorphism.

— The trigonal structure of carbamazepine, since its elucidation in 1987 and for several decades, was considered a polymorph. However, using a combination of physicochemical methods, it was recently established that the trigonal structure, which should have consisted solely of carbamazepine molecules, is a host-guest inclusion compound, where the carbamazepine molecules form a channel-type framework with solvent molecules embedded within the voids. The inclusion molecules will vary depending on the experimental conditions. It is the inclusion molecules that stabilize the trigonal crystal structure and enable its formation. Currently known inclusion compounds of carbamazepine are characterized by the presence of a small number of guest molecules in a highly disordered state, making their study quite labor-intensive. Various inclusion bodies of the trigonal form of carbamazepine can be classified as clathrates—compounds in which molecules of one substance (the "guest") are trapped within the crystal lattice of another substance (the "host"). The host molecules form a framework, while the guest molecules are located within it and held in place by weak intermolecular interactions, explained Daria Zheltikova.

Research into carbamazepine polymorphism and its formation of various crystalline forms began quite some time ago and was conducted as part of several projects implemented over the years with support from the Russian Foundation for Basic Research, the Russian Science Foundation, and the Priority-2030 program. The results were published in peer-reviewed international journals. This study continues work conducted earlier in the previous stages of the NSU Physics Faculty's youth competition "X-ray, Synchrotron, and Neutron Methods of Interdisciplinary Research," with support from the Priority-2030 program.

The aim of this study is to optimize the conditions for obtaining single crystals of carbamazepine clathrates with various guest molecules using various crystallization techniques and their analysis using a set of physicochemical methods.

Such exploratory work, despite its significant fundamental component, often leads to the establishment of the existence of new, previously unknown polymorphic modifications of medicinal compounds, which has direct practical significance, and also establishes correlations between the parameters and results of crystallization experiments, which can be useful in the study of systems similar in structure and properties.

One of the new scientific results obtained in this study is the demonstration of the template effect of small amounts of structurally similar compounds on the self-assembly and crystallization of the channel trigonal structure of carbamazepine using various methods—a mechanochemical approach, solution crystallization, and melt crystallization. Saturated carboxylic acids and alkanes—compounds containing a long, unbranched carbon chain—were used as structurally similar compounds. The template effect observed in the preparation of carbamazepine clathrates is based on the ability of the template (in this case, various carboxylic acids and alkanes) to organize the reactant (carbamazepine) molecules around itself, enabling the formation of a seed cluster, which serves as a precursor for the targeted formation of the final crystalline structure. All newly obtained compounds are clathrates of the trigonal form of carbamazepine, that is, the structure of carbamazepine contains inclusion molecules of the corresponding acids and alkanes.

— Currently, we are focused on optimizing methods for obtaining single crystals of various carbamazepine clathrates for further study and investigation of their stability at elevated temperatures. We obtained nine clathrates with saturated carboxylic acids and alkanes under various conditions. Our study examined six carboxylic acids and three alkanes. We have focused on only a few compounds from each group, as obtaining single-crystal samples for each individual compound is quite labor-intensive due to differences in formation conditions and certain experimental details. The compounds obtained have an acicular morphology—in simpler terms, they are thin, needle-like crystals. In some cases, the needle size is so small that it precludes single-crystal X-ray diffraction analysis using laboratory diffractometers. For this reason, not all of them have had their crystal structures determined yet. We characterized compounds whose crystal structures had not been obtained using Raman and NMR spectroscopy, said Daria Zheltikova.
