For the second year, under the guidance of associate professor, Ph.D. Galina Okolnikova, graduate students Georgy Tikhonov and Grigory Grishin have been engaged in research at RUDN at the junction of two priority areas - construction and nanotechnology. In the laboratories of the Engineering Academy, they study characteristics of modified concrete - nano-concrete. In 2018, both students became participants of the “RUDN International Scholarship” academic mobility support program, which allowed them to expand their knowledge and gain new experience from leading scientists at the University of Al-Farabi KazNU (Kazakhstan). Internship in Almaty was not limited to lectures and practical modules. They presented the results of their research in poster presentations at the International Conference "Problems of Technological Combustion", where they were praised by the competent jury. The chairman of the jury was Zulhair Mansurov, winner of the UNESCO award for his contribution to the development of nanoscience and natotechnology.
“My research is devoted to the study of manufacturing technology of valves with a new four-row sickle profile AV500P. It is able to compete in foreign markets with expensive screw fittings. In quality, this class of reinforcement is not inferior to foreign analogues, and in production it is much more economical, because standard rolling equipment may be used. The armature has already been rolled at the Tula Metal Rolling Plant and the West Siberian Metallurgical Plant in the city of Novokuznetsk, ”said Georgy Tikhonov.
“Nanobeton opens up new opportunities for design and construction. It is distinguished by its durability, lightness, and resistance to thermal extremes, which makes it possible to reduce the cost of building new objects and to facilitate the restoration of old structures. High physical and mechanical characteristics are created due to special particles - nanoiCiators In my research, I present the technology of reinforcement of structures with composite fibers, which is the use of basalt and carbon nets as part of nano-concrete, ” said Grigory Grishin.
Students’ internship at Al-Farabi Kazakh National University lasted a month. During this time, they were able to replenish their knowledge with relevant information, visit laboratories of research institutes, such as the Kazakhstan Road Research Institute and the Institute for Problems in Combustion, and demonstrate the results of their scientific work. Full of new impressions and experiences, they plan to continue their research at RUDN.
Since September 2018, the first joint educational project of RUDN and Al-Farabi Kazakh National University has been implemented - the master's program of dual diplomas in the framework of the SCO University program “Nanotechnology”. In October of the same year, a joint master’s program of inclusive education in the “Construction” area was launched, and in November 2018, the delegation signed a new Agreement on inclusive training in “Nanotechnologies and microsystem technology”, defining the next level of joint work in the upcoming 2019.
A chemist from RUDN University has developed a catalyst for the production of eugenol acetate, a substance that destroys the larvae of mosquitoes transmitting dangerous diseases, being a safe chemical for human health.
RUDN soil scientists have revealed a direct correlation between the rate of soil formation of carbon dioxide, called CO2 emissions, and the content of microbial biomass in it. It is known that CO2 emission from soil is mainly conditioned by respiration of soil microorganisms and plant roots. The more CO2 soil emits, the more microbial biomass it usually contains. It was shown that CO2 emission by chernozem of different ecosystems (or different types of land use) correlates with the content of microbial biomass, and most closely with the rate of its microbial respiration. And the soil with good microbial properties has the “best quality”, is more fertile, provides the highest yield of crops and other plant biomass.
A RUDN chemist has synthesized a catalyst for the production of gamma-valerolactone — an energy-intensive “green” biofuel. The catalyst based on zirconium dioxide and zeolite has shown high efficiency in converting the waste of wood plant materials — methyl levulinate — to gamma-valerolactone.
