1. Wires made of an aluminum alloy and a small amount of zirconium can withstand heating up to 400 ° C without deterioration. Testing the wire showed that after adding zirconium, the heat resistance almost doubled, and the electrical conductivity practically did not decrease. According to scientists, increasing the heat resistance of the alloy will allow it to be used not only for power lines, but also in various aircraft, where it is critical to minimize the mass of all parts.



2. Researchers from Russia and the Czech Republic for the first time were able to create liquid crystal polymers, the surface topography of which can be controlled using lasers. Scientists used polymethacrylate as the basis of polymers. Such materials will find application as non-contact surface modifiers.



3. Tomsk Polytechnic University became an associate member of the collaboration with the Large Hadron Collider at the European Center for Nuclear Research (CERN) - NA64. In this collaboration, scientists at the Tomsk Polytechnic are involved in analyzing data from the accelerator, modeling experiments, and general work. In NA64, scientists from different countries using the SPS accelerator try to create the conditions under which dark photons could form.



4. Russian scientists from ITMO University, together with their American counterparts, have created a program that allows you to quickly and efficiently find similar sites in the genomes of different animals. This is necessary in order to understand how two species are close to each other and how far they diverged from a common ancestor during evolution.



5. Researchers at the Institute of Advanced Materials Physics of the Ufa State Aviation Technical University have developed scientific and technical approaches and a way to increase the strength of VT8M-1 titanium alloy. The advanced alloy is characterized by an ultrafine-grained structure and increased strength. Increased strength properties are critical parameters for the latest generation aircraft engines. It is assumed that such an alloy can be used, inter alia, in the production of a new domestic aircraft engine PD-14.
