On 5 December, the Moscow Chamber of Commerce and Industry held an award ceremony for the winners of the Award by the all-Russian Society of Inventors and Innovators “RSII 2023”. Among the winners was Dmitry Zhukalin, Associate Professor at the Department of Semiconductor Physics and Microelectronics.
This year, 722 applications were submitted for the competition of Russian inventors. 224 inventors from 36 regions of the Russian Federation were selected during the regional stage of the competition. The expert jury then chose 10 laureates of the RSII Award and 10 laureates of the RSII Youth Award.
The authors of the best project presented by VSU, “Streamer nanoperforator”, are members of the Department of Semiconductor Physics and Microelectronics of the Faculty of Physics Dmitry Zhukalin, Igor Dolgikh, and Larisa Bityutskaya.
“In our project we suggest a compact and energy-efficient device for controlled microperforation of paper. The device allows for the non-contact (i.e. without any impurities) microperforation of any type of paper with a controlled diameter and depth. Using cold microperforation with a pulsed magnetic field we can obtain holes of up to 5 µm (smaller than those obtained using laser perforation) without the carbonisation of the edges of the holes. Perforated paper has various usages (e.g., filter paper, medical face masks). It is a disposable material which is more practical to manufacture on site using compact portable equipment, rather than to transport it from production plants”, said Dmitry Zhukalin.
