Документ Energy Spectra of the Graphene-based Fibonacci Superlattice Modulated by the Fermi Velocity Barriers(2016) Korol, Anatoliy; Litvynchuk (Vorontsova), Svitlana; Baglyuk, Sergey; Isai, ValeriyThe energy spectra of the Weyl-Dirac quasi-electrons for this SL are calculated with the help of the transfer matrix method in the continuum model. The Fibonacci quasi-periodic modulation in graphene superlattices with the velocity barriers can be effectively realized by virtue of a difference in the velocity barrier values.Документ Über zwei gruppen von relaxationsübergängen im polybutadien und seinen copolymeren oberhalb der glastemperatur(1988) Shut, Nikolai; Baglyuk, Sergey; Lazarenko, Mykhailo; Bartenev, GeorgijWe studied the continuous spectra of relaxation time, spectra of internal friction and heat capacity of atactic polybutadiene and its copolymers, which contained 26 and 50% acrylonitrile units. The physical nature of relaxation transitions above the glass transition temperature identified and calculated their characteristics.Документ The effect butadiene and acrylonitrile components on the relaxation properties of butadiene-akrylonitrile copolymers(1988) Bartenev, Georgij; Shut, Nikolai; Baglyuk, Sergey; Tulinova, V.The majority of relaxation transitions in poly (butadiene-co- acrylonitrile) that are observed above the glass transitions temperature are connected with the butadiene component. The acrylonitrile component affect the glass transitions temperature and temperature of chemical decomposition of the polymer, and it leads also to the occurrence of the relaxation process connected with the mobility of local dipole-dipole cross bonds.
