JSC Advanced Research Institute of Inorganic Materials named after Academician A.A.Bochvar, the peer of the Soviet and Russian nuclear industry, began its activity by solving material science and technological problems. Established as the Institute of Special Metals of the NKVD (this is its first of eight names), it took part in the most important state projects in the nuclear industry. Its scientific staff contributed to the first Soviet atomic project implementation. The Institute developed fuel for the first nuclear power plant in Obninsk, the first fast neutron reactor, and for the world’s first nuclear icebreaker "Lenin". In 1994, ARIIM was granted the status of the State Scientific Centre of the Russian Federation. On the eve of the 80th anniversary of the Institute, which was named NII-9 in Soviet times for security reasons, Leonid Alexandrovich Karpyuk, Director General of ARIIM JSC, answered our questions.

MOTORIZED SAMPLE POSITIONING SYSTEM EQUIPPED WITH AN OPTICAL MODULE DOI: https://doi.org/10.22184/1993-8578.2025.18.7-8.410.418
Scanning capillary microscopy is becoming increasingly important in the study of living objects, as it enables direct, non-contact visualization of cell and tissue morphology in a natural aqueous environment. Nanometer-scale, non-contact imaging and functional analysis of fragile biological samples are becoming a cornerstone of modern biomedical research. The unique capabilities of SCM for live-cell imaging, combined with multiparametric analysis and nanoscale delivery, make this method indispensable for life sciences, electrochemistry, biotechnology, and medicine. In this paper, we will discuss in detail the implementation of a mechanical system capillary microscope.

PROMISING SENSOR MATERIALS BASED ON IRON (III) HEXACYANOFERRATE MODIFIED WITH NANOSIZED SILVER DOI: https://doi.org/10.22184/1993-8578.2025.18.7-8.458.465
As part of the study, a method for modifying materials based on iron hexacyanoferrates (III) with nanoscale silver (HCF Fe–Ag) was developed. Iron (III) hexacyanoferrate (HCF Fe) was obtained by chemical co-precipitation in aqueous solutions. The presence of a basic crystalline phase of iron (III) hexacyanoferrate with a cubic face-centered crystal lattice (Fm3m) was found in the samples by powder diffractometry. To modify iron (III) hexacyanoferrate samples with silver, silver nitrate was used as a precursor, which was reduced with sodium borohydride. It has been established by powder diffractometry, scanning electron microscopy, and energy-dispersive X-ray spectroscopy that silver on the surface of iron hexacyanoferrate (III) is in the form of two crystalline phases – in the form of silver nanoparticles and silver hexacyanoferrate (III), which is formed as a result of the interaction of silver precursor with iron hexacyanoferrate (III) on the surface of a colloidal particle.

DEVELOPMENT OF A MICRO-OPTO-MECHANICAL PRESSURE SENSOR BASED ON THE MACH-ZEHNDER INTERFEROMETER DOI: https://doi.org/10.22184/1993-8578.2025.18.7-8.420.431
In this paper shows the possibility of creating sensitive elements based on integrated optical technology and MEMS structures. A prototype of a pressure sensor operating on the principle of optical interference is presented. The sensor’s sensing element is based on a Mach-Zehnder interferometer, one of the arms of which is located on a deformable membrane. The optical scheme of the interferometer is implemented on Si3N4 integrated waveguides. In the course of the study, a theoretical assessment of the effect of membrane deformation on waveguide geometry was performed. The calculations performed were tested during experimental studies of models of a micro-opto-mechanical pressure sensor with different configurations of the interferometer arms. As a result of the research, a technological basis for integrated optical sensors based on silicon nitride waveguides and MEMS technology for the formation of membranes on silicon substrates has been developed.

STUDY OF MECHANICAL PROPERTIES OF MOISTURESATURATED SILICA GEL GRANULES DOI: https://doi.org/10.22184/1993-8578.2025.18.7-8.450.456
The feasibility of mechanical testing of soft, water-saturated silica gel granules using the commercially available NanoScan-4D nanohardness tester was demonstrated. A method for determining the strength and elastic properties of silica gel granules under compression by flat punches was developed and tested. Load ranges reliably causing specimen failure were experimentally established. An analysis of the loading diagrams obtained during testing allowed for determining the elastic modulus and estimating the adhesion forces between the silica gel and punch surfaces. A fatigue testing method for granules at the resonant frequency of the nanohardness tester’s mechanical system is proposed, enabling the evaluation of mechanical property degradation under cyclic loading. The research results confirm the applicability of the nanomechanical approach for quantitatively assessing the strength properties, elastic modulus, and adhesion characteristics of hydrated porous materials. The proposed method can be used in the development and optimization of silica gel adsorbents, catalyst carriers and composite materials operated under conditions of cyclic loads, variable humidity and temperature.
