  • Amperometric glucose biosensor with the IrNPs/Ludox – modified enzyme matrix 
    Shkotova, L.V.; Woloshina, I.M.; Kovalchuk, V.V.; Zhybak, M.T.; Dzyadevych, S.V. (Вiopolymers and Cell, 2018)
    Aim. To develop an amperometric biosensor based on glucose oxidase (1.1.3.4) from Aspergillus niger immobilized in the IrNPs/Ludox/GOx matrix for glucose detection. Methods. To achieve a highly selective and sensitive ...
  • Cluster morphology silicon's nanoparticle 
    Kovalchuk, V.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2007)
    It is proposed to use silicon polyhedral atomic clusters (ACs) in the study of nanoparticles. A scheme of the parametrized density functional theory for calculations of the atomic and electronic structures of these ...
  • Polymorphism in chalcogenides of alkalineearth metals 
    Drozdov, V.А.; Pozhivatenko, V.V.; Drozdov, М.А.; Kovalchuk, V.V.; Moiseev, L.M.; Moiseeva, V.O. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2005)
    Calculations of structural phase transitions В1 - В2 under pressure in chalcogenides of alkaline-earth metals were carried out on the basis of approach of the local density functional theory, where as a fitting used was ...
  • Theoretical investigation of light absorption and scattering by nanoparticles 
    Pokutnyi, S.I.; Kovalchuk, V.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2000)
    In the framework of the dipole approximation we predict theoretically high magnitudes of: (1) oscillator strength transitions, and (2) the resonance light cattering (σss(w, a)) and absorption (σabs(ω, a)) cross-sections. ...
