Item Nanotechnology in medicine(Sumy State University, 2017) Svikolnik, A.In today's world often facing humanity faces global problems. Significant help in solving various problems can provide nanotechnology. In some biology and other sciences often use them is crucial.Item MD simulation of AlCoCuFeNi high-entropy alloy nanoparticle(Sumy State University, 2016) Kushnerov, O.I.High entropy alloys (HEA) are metallic compounds containing from 5 to 13 metallic elements in equiatomic ratios. In HEAs, because of the high mixing entropy, formation of brittle intermetallic phases is usually avoided and simple solid solutions are rather stabilized (BCC and/or FCC). This study used molecular dynamics (MD) package LAMMPS to simulate the AlCoCuFeNi nanoparticle (NP) crystallization.Item A self-assembly of nanoparticles(Sumy State University, 2014) Ющенко, Ольга Володимирівна; Ющенко, Ольга Владимировна; Yushchenko, Olha Volodymyrivna; Бадалян, Анна Юріївна; Бадалян, Анна Юрьевна; Badalian, Anna Yuriivna; Bratash, S.O.Nanotechnology achievements are often connected to material science because the design of a wide range of advanced nanostructured materials will reduce the size of the components of many devices. But nanoscience today is more interested in the formation of nanoassemblies and further coupling of them into the nanostructured materials.Item Effective Landau-Lifshitz-Gilbert equation for a conducting nanoparticle(Сумський державний університет, 2013) Денисов, Станіслав Іванович; Денисов, Станислав Иванович; Denysov, Stanislav Ivanovych; Бабич, Ганна Валеріївна; Бабич, Анна Валерьевна; Babych, Hanna ValeriivnaWe study the role of conductivity in the magnetization dynamics of single-domain ferromagnetic particles. Our approach is based on the coupled system of Maxwell’s and Landau-Lifshitz-Gilbert (LLG) equations. We show that the effective LLG equation for a conducting particle contains two additional terms compared to the ordinary LLG equation. One of them is responsible for the conductivity contribution to the damping parameter.

In this study, for the first time a novelactinomycete strain Streptomyces glaucus71 MD isolated from a soy rhizosphere in Georgiais for the first time extensively characterized and utilized for the synthesis of silver nanoparticles. Scanning Electron Microscope (SEM) allowed observing extracellular synthesis of nanoparticles, which has many advantages from the point of view of applications. Production of silver nanoparticles proceeded extracellularlywith the participation of another microorganism, bluegreen microalgae Spirulinaplatensis (S. platensis). In this study it is shown that the production rate of the nanoparticles depends not only on the initial concentration of AgNO3 but also varies with time in a nonmonotonic way. SEM study of silver nanoparticles remaining on the surface of microalgae revealed that after 1 day of exposure to 1 mM AgNO3 nanoparticles were arranged as long aggregates along S. platensiscells strongly damaged by silver ions. However, after 5 days of exposure to silver S. platensiscells looked completely recovered and the nanoparticles were distributed more uniformly on the surface of the cells.
