These anodes allow increasing the specific energy of lithium-ion batteries up to 250–300 W∙h/kg Two types of textile shields for protection against electromagnetic radiation (EMR) in the radio frequency range have been proposed: fabrics modified with metal nanoparticles and hybrid knitted fabrics with knitted steel threads. The screen shielding efficiency is 5–20 dB, which is assessed as "good" on the scale of shielding of textiles of general use (FTTS-FA-003-2005). The textiles can be used to protect people and electronic equipment from non-ionizing EMR During the work for the manufacture of multifunctional textile material, it is proposed to use the structure of two-layer knitwear, which allows the use of two types of raw materials providing their clear separation in two different layers. The physical and mechanical properties of the developed samples of knitted fabrics have been investigated, their resistance to one-time action of an open flame is established and expediency of use in production of underwear for protection against thermal influences is analyzed The technologies for the production of polymer composites based on polylactic acid filled with graphite and carbon fiber for 3D printing of technical products and thermoplastic starch using epoxidized soybean oil and wood flour as modifiers have been developed. The technology based on PVA and PVAc in a composition with starch, chitosan, gelatin to obtain ultra-thin fibers by electrospinng also have been developed. The technology of fire-protective polymer coating of reactive type for steel structures has been developed, which provides the limit of fire resistance of 120 min and has a service life of up to 25 years Product Description popup.authors Ielina Tetiana V Ishchenko Olena V Arabuli Arsenii T Arabuli Svitlana I Barsukov Viacheslav Z Butenko Oksana O Halavska Liudmyla Ye Dzikovich Тetiana A Dmytrenko Liudmyla A Kalafat Kostiantyn V Kyzymchuk Olena P Kyslova Olha V Koliada Maksym K Kuryptya Yaroslav A Liashok Iryna O Makieieva Iryna S Medvedieva Svitlana Yu Plavan Viktoriia P Savchenko Bohdan M Senyk Ilona V Slieptsov Oleksandr O Sova Nadiia V Tverdokhlib Viktor S Khomenko Volodymyr G Chernysh Oksana V popup.nrat_date 2022-03-09 Close
