The high-power and long-pulse operation of tokamak will cause excessive particle flux and heat load on the divertor target plate. The surface of the target plate will be subject to intense sputtering, and the thermal load of the target plate will exceed the material/component limit.

Credit: Kazan Federal University Problems for eigenmodes of a two-layered dielectric microcavity have become widespread thanks to the research of A.I. Nosich, E.I. Smotrova, S.V. Boriskina and others since the beginning of the 21st century. The KFU team first tackled this topic in 2014; undergraduates started working under the guidance of Evgeny Karchevsky, Professor of the Department of Applied Mathematics of the Institute of Computational Mathematics and Information Technology. In this paper, the researchers discuss a model of a 2D active microcavity with a piercing hole and the possibility...

 E-Mail Scientists from Tomsk Polytechnic University and Université Grenoble Alpes (France) have proposed a more accurate method for loading capability assessment of power transformers. As an example, the scientists defined the loading capability of the power transformer in Tomsk and Grenoble. The research findings are published in the International Journal of Electrical Power and Energy Systems (IF: 3,588, Q1). The cost of a power transformer can reach a few hundred million rubles that makes it the most expensive element of an electrical grid. Therefore, power engineers tend to use the lo...

Scientists at Skoltech Center for Energy Science and Technology have developed an enriched and scalable approach for increasing the capacity of a broad range of metal-ion battery cathode materials. An important advantage of the approach is its scalability. The process requires no sophisticated conditions and is relatively safe. Additionally, the reducing agents can be recycled after they react with the cathodes because their redox chemistry is reversible. These features make the method promising for large-scale applications.
