The results of the joint competition “X -ray, synchrotron, neutron methods for solving the problems of materials science” were summed up. This competition was organized by the Novosibirsk State University and the Siberian Department as part of the implementation of the research program (project) “Scientific justification and creation of infrastructure based on the use of synchrotron radiation for the diagnosis of functional and gradient materials”. It was attended by 29 projects in several relevant scientific areas, in particular, new and adapted methods for diagnosing the structure of the phase composition of functional-gradic materials, as well as materials obtained by the method of electron-beam additive production using synchrotron radiation, including the time of the study of the evolution of structural-phase composition and monitoring high -speed impulse impact. Also, the submitted projects touched on the hardware and technical equipment of experimental stations on the existing synchrotron infrastructure (stage) for their further adaptation on the source of the generation 4+ (TsKP SKIF). Also in youth projects, the results of comprehensive studies of the structure and properties of structural materials, metals, alloys obtained by the method of electron-beam additive production using synchrotron radiation were presented. Some works were devoted to the development of software, new approaches and algorithms for processing experimental data obtained using synchrotron radiation.
Projects were evaluated on a ten-point scale. Leading specialists from the Siberian Branch of the Russian Academy of Sciences, research institutes, and the Siberian Ring Photon Source Center for Collective Use evaluated the competition entries and assigned scores. The competition committee was chaired by Academician Vasily Fomin, Deputy Chairman of the Siberian Branch of the Russian Academy of Sciences and Scientific Director of the S. A. Khristianovich Institute of Theoretical and Applied Mechanics. Based on the number of points earned, 12 projects by 13 authors were selected. The top six winners received a one-time financial award of 180,000 rubles, while those finishing in 7th through 12th place received 120,000 rubles each.
The diplomas were presented to the competition winners at a meeting of the Presidium of the Siberian Branch of the Russian Academy of Sciences. Presenting the diplomas to the winners, SB RAS Chairman Academician Valentin Parmon expressed his hope that their work would be put into practice and, on behalf of the entire Siberian Branch of the Russian Academy of Sciences, congratulated the young scientists on their victory. Academician Vasily Fomin explained that the Siberian Branch of the Russian Academy of Sciences won a major grant, which NSU is also participating in. He clarified that the project's terms of reference stipulate that NSU will regularly hold competitions for young scientists for three years. Vasily Fomin also emphasized the importance of the current competition, the theme of which was related to their involvement in future work at the SKIF Collective Use Center.
"The winning projects primarily focus on the development of various diagnostic methods using X-ray and synchrotron radiation, as well as some materials research using these methods.

The competition winners briefly described their projects:
Grigory Zhdankin:
My project is dedicated to the design and calculation of the second-stage optical station at the SKIF "Monocrystal" Center for Collective Use. As its author, I needed to understand which combination of optical elements is optimal for generating a synchrotron radiation beam of the required size and intensity. Its key objective is to study molecular crystals using X-ray diffraction analysis under high pressure and low temperature conditions. Such studies are important for identifying the relationship between the structure of the substance being studied and its properties. Understanding this process will enable the development of new and improved drugs, as different polymorphic modifications have different properties that are important for the pharmaceutical industry. Photocrystallographic experiments under high pressure and low temperature conditions are also important for the creation of molecular switches. Winning this competition will help me realize my project.
Dmitry Shakirov:
The novelty of our project to create a digital twin of the adjustable mask at the SKIF Center for Collective Use lies in the fact that the entire facility (SKIF), including its components, is unique equipment, and digital twins of such equipment do not currently exist. The digital twin of the adjustable mask will be part of a comprehensive digital twin of the entire SKIF Center for Collective Use, which is being developed at the Institute of Computational Mathematics and Mathematical Geophysics (ICM&MG) SB RAS. The digital twin will significantly reduce the cost of servicing the facility and enable personnel training without damaging the physical product. The digital twin will enable virtual experiments and determine the performance of the facility in various situations, including emergency situations. The primary objective of achieving our project's stated goal is the creation and training of a neural network, which will serve as the basis for the digital twin of the adjustable mask. We decided to use a neural network to enable the simulation of virtual experiments in real time.
Stanislav Lukin:
The project I presented involves preparing samples of a particulate-filled polymer composite and conducting preliminary studies of their mechanical properties, taking into account the interfacial layer at the interface between the matrix and filler particles. Based on the results of this study, a preliminary design for an experiment at the synchrotron radiation source will be developed for in-situ investigation of the failure mechanisms and internal structure changes in the prepared samples under uniaxial tension. Further implementation of the experiment at the synchrotron radiation source will allow us to characterize changes in the properties of particulate-filled polymer composites under mechanical loading, and, consequently, changes in the properties of parts made from these materials during their use.
Artur Asylkaev:
— As part of the SKIF Center for Collective Use project, Station 1-3 "Fast Processes" will be installed by the end of 2025 to study phenomena such as the propagation of shock or detonation waves in a medium. Therefore, it is important to develop a method using synchrotron radiation to study the shock-wave compressibility of inert materials such as polytetrafluoroethylene (PTFE). Given the widespread use of inert materials (including in aircraft construction), it is essential to study their response to ultra-high pressures (which can be achieved using explosives). The practical significance of my work lies in determining the density dynamics of PTFE under high shock-wave loads, since synchrotron radiation, unlike traditional methods, allows us to determine the process dynamics.
Alexander Gorkusha:
My project is devoted to developing a diffraction technique for studying functionally graded materials based on nickel alloys. Its novelty lies in adapting a traditional X-ray analysis approach to specific objects—relief samples with uneven surfaces, where classical approaches often produce significant errors. The project's importance lies in creating a laboratory technique that will enable highly accurate determination of crystal lattice parameters and quantitative phase analysis, which is critical for the development and testing of new materials.
Ilya Gertsel:
Thermal stability is a fundamental property that determines the reliability and durability of materials in various industries. My method, using synchrotron radiation, allows for experiments that closely approximate the operating conditions of materials (temporally resolved thermal loading of materials). This allows us to determine the operating temperature range of real products before they are put into service. Currently, both the experimental methodology itself and the software for data processing are underdeveloped; these issues will be addressed in the future as part of the project.
I am very pleased to have won this competition, as it now provides the opportunity to develop the proposed methods using the unique SKIF facility.
Yuri Khomyakov:
— The title of my project is "Optical Design of the RFA-Geology Station at the SKIF Collective Use Center." The second-stage RFA-Geology station is currently the only planned station at the SKIF Collective Use Center with a high-field shifter (8 T) as an insertion device. It is expected to operate in the energy range of ~40-120 keV with SR beam transverse dimensions from ~10 μm to ~10 cm. The station will implement the following methods: energy-dispersive diffraction, microdiffraction, micro-XRF (including in a confocal configuration), and computed tomography.
The deep penetration of hard X-rays with photon energies of approximately 100 keV opens up broad prospects for geological research, including the study of natural materials, enabling non-destructive analysis of dense macroscopic samples (minerals, melts) containing significant concentrations of high-atomic-number elements. Such samples include, for example, mantle xenoliths (including diamond-bearing ones), as well as fragments of alkaline rock complexes associated with deposits of rare and rare-earth metals.
The combination of hard X-ray methods available at the RFA-Geology station will enable visualization of the internal structure of rock samples and the spatial distribution of mineral phases, identification of individual minerals, including new ones, and determination of the relative orientation of crystalline grains. Furthermore, the station will be used to study the structure and physical properties of mantle matter, determine fundamental constants and PVT equations of state for crystalline substances, liquids, and fluids, and study the kinetics of chemical reactions in situ at high pressures and temperatures.
The objective of this study is to develop a coordinated X-ray optical design for the RFA-Geologiya station for the use of SR in the hard band. The study will address the following objectives: substantiated selection and optimization of the insertion device; selection of the optical design; matching of the X-ray optics to the source; description of the station's hardware and technology; and X-ray optical calculations.
The research results will be incorporated into the conceptual design of the RFA-Geology station, which will serve as the basis for developing technical documentation and manufacturing unique scientific equipment.
