RUDN gathers leading experts at the International Urban Soil Symposium in New York (USA)
200 participants from Europe, America and Asia gathered at the New York Institute of Technology to share scientific insights on recycling urban waste, restoring the soil cover of territories, urban agriculture and developing urban green infrastructure.
“Soil pollution with heavy metals is one of the main negative consequences of urbanization and industrialization, which remains relevant for regions with different climatic conditions and level of economic development. The problem of soil pollution is relevant for issues of ecology, health, engineering preparation of territories and development of territories,”said Elvira Dovletyarova, deputy chairman of the organizing committee, director of the Department of Landscape Design and Sustainable Ecosystems (LPAUE).
RUDN scientists presented studies in the analysis of sustainable functioning of megacities' green infrastructure. The studies are based on the assessment of the state of soil cover, vegetation and climatic indicators of urban ecosystems. “The methods include both traditional and new approaches based on in situ analysis, i.e. in place. The results provide a list of indicators of ecological functions and ecosystem services of urban ecosystems, ”said associate professor Vyacheslav Vasenev and junior researcher Ramilla Gadzhiagayeva, who presented the project to the participants of the symposium.
The plenary sessions were also addressed by representatives of the municipal organizations of the city of New York, the US Department of Agriculture, and leading scientists from US universities - Cornell, Columbia, and New York. Various reports of speakers raised the issues of waste recycling, the effects of soil pollution on people, ways of creating and maintaining city improvement.
All participants noted the need for joint research activities of scientists from different countries. Within the framework of the symposium sections, they outlined the main areas of interaction for further research collaborations. Research will include problems of remediation and recultivation of urban soils, collection of data for analyzing the impact of urbanization on soil cover in various megalopolises of Europe and America, and recommendations for sustainable development of urban ecosystems. Field research will take place next year in the territory of urban ecosystems of Russia together with scientists from the USA, Germany and France.
The results of the joint work are planned to be discussed at the Soil Fest next year in New York. The festival will also be organized by RUDN University and the Institute of Urban Soils of New York.
A team of chemists from RUDN University suggested a universal method to synthesize thienoindolizine derivatives. Because of their special properties, these substances can be used to manufacture antibacterial and antitumor drugs, as well as new materials for optoelectronics.
Even if a black hole can be described with a mathematical model, it doesn’t mean it exists in reality. Some theoretical models are unstable: though they can be used to run mathematical calculations, from the point of view of physics they make no sense. A physicist from RUDN University developed an approach to finding such instability regions.
Chemists from RUDN University synthesized soluble biopolymers based on chitin from crab shells. Together with palladium, they form effective catalysts for organic reactions, and their nanoparticles can be re-used over ten times.
